State of California ATR RESOURCES BOARD September 30, 1977 Staff Report Evaluation of Almquist Manufacturing, Ltd. "Ram Jet Mint—Charger" device for Compliance with the Requirements of Section 27156 of the Vehicle Code Introduction Almquist Manufacturing Ltd., Milford, PA 18337 has submitted an application (see Appendix A) requesting an exemption from Section 27156 of the Californta Vehicle Code for its "Ram Jet Mini—Charger" device for installation on all 1977 and older mode} vehicles equipped with positive crankcase ventilation systems (PCY) except for the following: a) engines smaller than 140 cubic inch displacement b) Volkswagen vehicles c}) fuel injection gasoline powered vehicles d) diesel or supercharged vehicles Section 27156 of the Vehicle Code prohibits the installation, sale or advertisement of any device or mechanism which alters the performance or design of the vehicle‘s emission control systems. The Air Resources Board is empowered to exempt any device from this prohibition if a finding shows the device will not reduce the effectiveness of the emission control system.

Evaluation of Almquist Manufacturing, Ltd. "Ram Jet Mini—Charger" device for Compliance with the Requirements of Section 27156 of the Vehicle Code September 30, 1977 II. System Description and Function The "Ram Jet Mini—Charger" is an air bleed device installed in the hose between the PCV valve and intake manifold. (See Appendix A Page 3.) The device consists of an acetal copolymer cylindrical ribbed body with barbed inlet and outlet fittings, (that can be installed in either direction) a stainless steel spring, a nylon ball valve, a polyurethane filter, a stainless steel screen, and an acetal copolymer adjustable knob. The device permits filtered air to enter the PCV line. The amount of air is dependent on a combination of manifold vacuum and an adjustable knob setting which acts on the spring and ball valve which in turn limits the flow of intake air. The applicant has submitted a letter dated September 26, 1977 (Appendix B) stating that he will supply an 80 pores per inch (PPI) polyurethane filter with each device. Although the pore size is larger (0.012 inches) than the ARB criterion of 20 microns (.0008 inches), the staff is of the opinion that this pore size is in conformity with previously exempted air filters.

Evaluation of Almquist Manufacturing, Ltd. "Ram Jet Mini—Charger" device for Compliance with the Requirements of Section 27156 of the Vehicle Code September 30, 1977 III. System Evaluation The applicant did not supply any information concerning the air flow at various adjustment levels. Previous. exempt devices of a similar nature were non—adjustable. The staff therefore performed its own flow tests. The adjustable knob was first fully tightened and the device installed according to the diagram in Figure 1. Vacuum was varied from 18 inches of mercury down to 3 inches and back up to 18 inches. The knob was turned counterclockwise in one quarter turn increments up to 2 1/2 revolutions. The corresponding air flow was measured in cubic feet per hour with the greatest flow occuring when the knob was a quarter of a turn from the fully closed position. When decreasing vacuum from 18 in. Hg. to 3 in. Hg. the air flow ranged from 0.28 SCFM to 0.17 SCFM. With increasing vacuum, the air flow ranged from 0.53 SCFM at 3 in. Hg., to a maximum 1.2 SCFM at 7 inches Hg. and decreased rapidly to 0.17 SCFM between 7 to 8 inches of Mercury. Between 8 thru 18 inches of Hg. it remained constant at 0.17 SCFM (Figures 2 and 3). The ARB criteria is 0.5 SCFM (maximum) at greater than 7 inches of Hg. for engines greater than 140 cubfjc inches. The device met this criteria except for the range between 7 in. of Hg. and 8 in. of Hg. The staff is of the opinion that the effect of this narrow range . on emissions would not be significant (Figure 2).

Evaluation of Almquist Manufacturing, Ltd. "Ram Jet Mini—Charger" device for Compliance with the Requirements of Section 27156 of the Vehicle Code September 30, 1977 The applicant submitted 30 MPH and 50 MPH steady state emission data, dated January 2, 1974, which were performed by the Scott Research Laboratories, Inc. (see Appendix C). The official test procedure is the CVS test cycle and therefore the staff did not consider this data significant since it did not show emissions during acceleration or deceleration or at low speeds. IV. Manufacturer‘s Claims The manufacturer made the following advertising claims (Appendix A): a) "Guaranteed increased gasoline mileage——greatest fue! savings have been experienced in older and high mileage vehicles operating under Tow manifold vacuum/high load operating conditions." b) "Guaranteed smooth engine performance especially in older and high mileage vehicles or with engines that have over—rich fuel mixtures." The ARB staff belfeves that the device will not give significant benefits in fuel economy. Past experience has shown that for a typical engine in normal operating condition this amount of air will have an insignificant effect on the air—fuel ratio and there— fore no significant effect on fuel economy or emissions. For an older engine with rich carburetion there may be some small leaning effect at low speeds and loads.

Evaluation of Almguist Manufacturing, Ltd. "Ram Jet Mini—Charger" device for Compliance with the Requirements of Section 27156 of the Vehicle Code September 30, 1977 Y¥. Conclusion.and Recommendations Based on the ARB test data and the information submitted by the applicant, the staff concludes that the installation of this device in the specified vehicles will not result in increased emissions and recommends that Almquist Manufacturing Ltd. be granted an exemption for the "Ram Jet Mini—Charger" from the prohibitions of Vehicle Code Section 27156 for the 1977 and older model vehicles except those listed in Section I of this report and the following: ‘ ‘ e) Chrysler Electronic Lean Burn System f) Volvo 3—way catalyst g) Variable Venturi Carburetor Systems The staff therefore recommends adoption of Executive Order D—77.

Page 1 MINI—CHARGER "Ramjet Series" WHAT IT IS: The MINI—CHARCER is a patented (no. 3,118,435 and patent pending) device designed to function both as an intake manifold air bleed valve and liquid emissions vap— orizer. The device will also function as a "T" fitting for use with a vacuum gauge as described below.* *OPTIONAL FEATURE The clean—out knob may be removed at anytime and replaced with a special screw—in CONNECTOR for installation of a vacuum gauge or closed vacuum switch for use with a dash—mounted, economy driving, indicator lignt. ' YEHICLE APPLICATION AND ENGINE LIMITATIONS Two models fit all popular 1977 and older American and imported cars and light trucks equipped with PCY systems. Exceptions are engines smaller than 140 CID, Volkswagons, fuel injection, diesel or supercharged vehicles. HOW THE MINI—CHARGER WORKS: The MINI—CHARGER is designed to function automatically in the following two wayss 1. The spring—loaded ball valve opens whenever engine vacuum drops %below 4"Hg) which is when the carburetor‘s power circuit cuts in and the fuel—air mix becomes richer than necessary for optimum power and fuel economy. (Such "over—rich" carburetion commonly occurs when the vehicle is under hard acceleration, climbing hills, pulling heavy loads or when driven "hard"at high speeds or when "over—accelerating" which is a frequent driving error,.) Our tests indicate that the MINI—CHARGER has the capabllity of improving air—fuel ratios when the engine is operating under high load con— ditions without over—leaning or degrading performance., 2. The MINI—CHARGER‘s "smog trap" collects wet blow—by condensates containing heavy hydrocarbons for later aerating and vaporizing by lighter blow—by gases that pass through the internal baffling system. This feature is especially important during and prior to engine warm—up because this is when the blow—by contains the most water vapor and heavy < oil and fuel particles which otherwise interfere with complete combustion and may cause increased engine deposits and wear.

Knob can be replaced with threaded barb (available from factory) for quick and easy attachment of vacuum gauge or to a closed vacuum switch for use with a permanently dash—mounted driving light which will function as a driving indicator. (A vacuum gauge is recognized as one of the best means of accomplishing economical driving habits.) *NOTE: All performance claims are based on actual user reports (which may be MORE or LESS depending on vehicle make, ° mileage, age, condition, optional equipment and when, where and how the vehicle is driven.) f DOUBLE GUARANTEE The MINI—CHARGER is guaranteed to improve mileage and performance as advertised or purchase price will be refunded by dealer anytime during the first year after purchase. The MINI—CHAPGER is further guaranteed by the factory agsinst defect in material or workmanship for as long as purchaser owns vehicle or replacement will be made free of charge. a

Page 3 INSTALLATION INSTW.UCTICNS The MINI—CHARGER can be installed easily in just minutes directly in the PCV vent line in most cars and light trucks (1963 to present)*. Here;s how : 1. After engine is warmed to normual operating temperature, shut off engine and lift hood. Remove air cleaner if necessary. 2. Locate the large PCV vent line {which is usually a rubber hbse about the diameter of your finger) that leads from the PCV valve to a point of entry near the carburetor base. Cut PCV vent hose with a sharp knife as close to carburetor as possible———allowing room so MINI—CHARGER will not touch any moving or hot parts. 3. Insgert and clamp MINI—CHARGER nipples snugely into cut ends of PCV HOSE. If hose appears old or hard or partially clogged, replace it. The MINI—CHARGER may be installed in any angle or direction *NCTE: Some engines require aAspecial adaptor kit which includes a short length of PCY vent hose which is supplied free of additional charge.

Page 4 ADJUSTMENT The MINI—CHARGER is factory adjusted to fit all popular cars in good mechanical condition,. However, valve action should always be checked immediatley after installation or cleaning, tobesurevalve closes when the engineis_ _idling. _ CHECK VALVE ACTION with engine idling by placing finger over end of air inlet. A "popping" sound should be heard when finger is removed. If a steady "swishing" or "hissing" sound of air is heard at idle, turn knob counter—clockwise until air hiss sound stops——indicating that the valve is closed. Remember,_ + the air valve must always CLOSE at idle. SERYICING: Remove filter ring and clean filter element in suitable solvent every 5,000 miles (sooner if vehicle is driven in dusty areas). Also check PCY line and clean or replace PCV valve at regular intervals as recommended in your car owners manual. The MINI—CHARGER valve may be cleaned without removing the device from the line by simply screwing out the knob and pouring in a small amount (equivalent to a tablespoon} of any good carburetor cleaner to flush out the valving mech— anism. Use a wipe cloth to catch excess solvent that flushes out the MINI—CHAPCER‘s air intake as you rotate it. Do this only when the engifie is shut OFF. # # 4# 4# THE MINI~CHARGER IS MANUFACTURED BY ALMGUIST MFG. COMPANY, MILFORD, PA. 18337

Page 5 PRICE: Average retail price of the MINL—CHARGER is $9.95 installed. This includes inspection and cleaning of the PCV valve and blowing out the PCY vent hose. Extra lengths of approved PCY hose are included in all dealer shipments so that replacement can be made of part or all of the present PCV line since we find that approximately 50% of all PCV hoses are partially clogged or deteriorated beyond further use. NOTE: Labels will have product name, patent number and patent pending. Aluminum snap ring will be changed to plastic with short "ears" for easy grasping and removal of filter element. Extra filter elements will be supplied with each unit.

SRL 1415 01 0174 (Revised 2/8/74) 1.0 INTRODUCTION Scott Research Léboratories, Inc. performed a series of steady state emission and economy tests on a vehicle provided by the sponsor on January 2, 1974. The objective of the tests was to determine the effect of the sponsor‘s two prototype devices on the exhaust emitted and fuel consumed by the test vehicle. Described below are the test vehicle, devices, procedures, and results obtained. 2.0 DESCRIPTION OF TEST VEHICLE All tests were performed using the sponsor‘s 1971 Monte Carlo (VIN 138750B175149) which had an automatic transmission, a 2 bbl carburetor, and an eight cylinder 350 CID engine. Following each test idle speed was 580 rpm in drive, dwell was 28.5, and timing was 7° erpc. All tests were performed using Indolene #30 gasoline. The odometer registered 73,568 miles at the start of testing. 3.0 DESCRIPTION OF DEVICES Scott performed tests using two different prototype devices referred to by fhe‘sponsor as "Fuel Tool" devices. Device A was con— structed of clear plastic and had an inlet air adjustment. Device B was black plastic and had no inlet air adjustment. Either device could be installed in the hose between the vehicle‘s PCV valve and carburetor. Each device allowed varying amounts of air (dependant on vacuum) to be bled into the vehicle‘s carburetor through the PCV line. 4.0 DESCRIPTION OF TESTS AND TEST PROCEDURES Upon receipt of the test vehicle Scott measured idle speed, timing, and dwell to insure compliance with manufacturer‘s specifications. A side tank of Indolene #30 gasoline was installed and the vehicle was warmed—up by operating it on a dynamometer at 50 mph and road load {4000 pounds inertia). Emission and fuel economy tests were then performed with and without the sponsor‘s device installed while operating the vehicle at 50 and 30 mph. Two tests were perfomed at an increased load setting (18.4 rhp at 50 mph) at the sponsor‘s request. All other tests were per— formed at road load (12.0 rhp at 50 mph). SCOTT RESEARCH LABC®‘TORIES, INC

SRL 1415 01 0174 Each test consisted of measuring the emissions of unburned hydrocarbons, carbon monoxide, and carbon dioxide on a grams/mile basis. Fuel economy was then calculated on a miles per gallon basis using the —emission data and the Environmental Protections Agency‘s carbon balance formula. 4.0 SUMMARY OF TEST RESULTS Economy and emission data for each test is summarized in Table 1. Table 2 presents the calculations used to derive the Table 1 data. XK‘l! SCOTT RESEARCH LABORATORINS, INC, n Nt | —

MANUFACTURERs: Almquist Mfg. Ltd. Date: August 26, 1977 ADDLTIONAL INFORMATION FOR "Ramjet Mini—Charger" PCV Hose Attached Device (1) New label as shown (2) With adjustment set at maximum air flow (knob screwed clockwise IN), device permits no air flow at manifold vacuums higher than four (4),inches of mercury. At vacuums lower than four inches of mercury, the air flow is lesgs than similar PCY connected air bleed devices {such asthe Ball—Matic Air Injector and Albano Air Jet which have already received exemption from the air resources board). When the engine is not operating, the ball closes against the upper valve seat to prevent crankease vapor from escaping into the atmosphere,. The ball valve also closes against its upper seat in the event of an engine back—fire. (3) The part number, name, specifications and material of all the working components are as follows: Partf# MS2 — 2A———Body: Acetal Copolymer (Celcon) virgin quality, Note that this material can withstand continuous use temperatures of 220°F with intermittent temperatures of between 220° to 300°F without sacrifice of properties. Part# MS2 — 2B———End Pieces 121; (same material as above body). ~ Part# MS2 — 2C———Adjusting Enob: (same material as above body). Part# MS2 — 2D———Ball. Valve: 7/16" diameter plus and minus ,010". NYLON (Dupont"s Zytel 101 Composition). Maximum usable temperature is 360°F. Res1stant to attack from oil, gasoline and the weak acids in crankcease blow—by. Part# MS—E Spring: Stainless, Speel. Part# MS—F Screen: Stainless Steel 010" wire diameter %£ 40 X 40 mesh. Part# MS2—G Filter Element: Porous polyurethane foam #45PPI. Page 1 of 2

(4) We call your particular attention to pages 14 thru 21 in the enclosed.book containing specifications of engineering resins, You will. note that the material {(Acetal Copolymer) that we use for body parts compares favorably and often surpasses nylon with respect to resistance to heat, stress, gasoline and oil. From this data you can see that our device will easily outlast the neophrene—buna vent hose to which it is attached. Celenese Corporation engineers originally recom— mended the use of Celcon (Acetal Copolymer) for our specific automotive application, We based our lifetime of car guarantee on field experience of over two years that proved that the plastic parts will not deteriorate even after prolonged use. We also made numerous tests with prototypes made from Celcon,. These test included the followings (A) Soaking for over 180 days in gasoline and old {dirty) crankease oil solution which proved no apparent deterioration of materials. (B) Over 50 cycles of intermittently freezing and . boiling the device (in water) to determine the effect on material and press fit of parts (all tesats were positive). (C) Striking assembled..device with heavy rubber mallet at freezing, 100, 150, 220°F temperatures (all tests were positive). (D) Actual working production models have satis— factorily operated for 55,000 to over 100,000 miles in six American made cars without deterioration of _either the Acetal Copolymer or the Nylon. (E) Numerous 12 to 24 month "heat" tests were made with actual working production models placed flush against the intake manifolds and valve covers on Chevrolet, Ford and Plymouth automobiles. In no case was there any deterioration of material. Page 2 of 2
