(This report has been reviewed by the staff of the California Air Resources
Board and approved for publication. Approval does not signify that the
contents necessarily reflect the views and policies of the Air Resources
Board, nor does mention of trade names or commercial products constitute
endorsement or recommendation for use. )

    Condensator, Inc. has requested that their 1978 Executive Order

D—69—1 be updated to include 1983 and older model—year vehicles and that

their new Model C device receive limited exemption.

     The Board performed comparative exhaust emission tests on the Model

B device and an engineering evaluation of the Model C device and

determined that neither device would reduce the effectiveness of the

engine‘s emission control components for the vehicle models as requested.

     The staff, therefore, recommends that the requested exemptions be

granted and that Executive Order D—69—2 be adopted.

                                 AIR RESOURCES BOARD

      Evaluation of Condensator, Inc.‘s Models B and C Condensator
Supplementary Carburetor for Exemption from the Prohibitions of Vehicle Code
Section 27156


        Condensator, Inc., 2010 Trimble Way, Sacramento, CA 95825, has applied

for update exemption for Model B and Model C Condensator Supplementary

Carburetor.      Exemption is sought for use of these devices on the vehicles, by

model, listed below:

Model B

        i)     1983 and older model—year gasoline powered motor vehicles equipped

              with either three—way catalyst with feed—back controls or oxidation

               catalyst emission controls.

Model C

      11)      1983 and older model—year motor vehicles.

        The two models differ slightly in that the Model B is a combination air

bleed and oil separator while the Model C is an oil separator only.

        The Board performed comparative exhaust emissions tests on the Model B

device and evaluated the operating principles of the Model C device.      This

report describes the test results and evaluation of both devices.


        The results of the Board‘s comparative exhaust emission tests revealed

that no significant emissions increase was found with the use of the Model B

device.      Testing was performed on a vehicle equipped with three—way catalyst

and feed—back controls which could be sensitive to the effects of the device.

The Model C device was found, through an engineering evaluation, not to reduce

the effectiveness of the poliution control devices found on vehicies in which

the Model B is not applicable.


       Based on no adverse emissions impact with the use of either Model B or

Model C Condensator Supplementary Carburetor, the staff recommends that

Condensator, Inc., be granted exemption from the prohibitions in Yehicle Code

Section 27156     for the vehicles as requested and that Executive Order B—69—2

be adopted.


       The Condensator Supplementary Carburetor Models B and C are similar in

appearance.     Both have a metal body with three internal passages leading

through an absorbant separator containing small beads retained by wire mesh to

an enclosed collector.      Two of the passages allow for a series connection to

the vacuum hose of the positive crankcase ventilation (PCV) system between the

PCY valve and intake manifold.     The third passage is vented to the atmosphere

and has a 0.040 inch fixed orifice.      The collector is a one quart glass jJar

with a threaded mouth which screws onto the bottom of the metal body.      The

external opening of each passage is threaded to accept a fitting.      The Model C

maintains the same two connections to the PCV system but seals the third

passage to the air bleed vent.

       In operation, blow—by gases from the crankcase which normally are pulled

into the intake manifold are routed through the device.      The crankcase gases

combined with suspended oil particles are separated as they circulate in the

device.     The entrapped oil fs accumulated at the bottom of the jar while the

gases proceeds to the intake manifold.      The manifold vacuum aiso pulls air

into the device through the device‘s air bleed vent.     The incoming air

combines with the crankcases gases and dilutes them.     The diluted blow—by

gases is then mixed with the fresh air/fuel mixture in the intake manifold and

is subsequently burned during combustion in the cylinders.


     Two test vehicles were selected for the evaluation of the Condensator

Model B device.     Each vehicle was chosen from local rental fleets and is

described in Table 1.     Comparative CVS—75 tests were run, two tests without

the device (baseline) and two tests with the device, for direct comparison.

All tests were performed according to the procedures as given in the Code of

Federal Regulations Part 86:00.

     The averaged comparative exhaust emission and fuel economy results are

found in Table 2.    All tests were performed at the Board‘s Haagen—Smit

Laboratory in El Monte, California.

        The Board has evaluated Condensator devices since their inception in

1976.    The earliest Condensator device, the Model A, is similar to the

present Model B device except that it uses a 0.060 inch orifice air bleed

vent.    The size of the orifice used in the Condensator devices is of

concern.     Late model—year vehicles are calibrated to operate on precise

adjustments of the engine‘s emission controlling components.         The addition

of an air bleed vent may upset the designed function of these components

and may cause emissions to increase.       Such was the case for Vehicle #1 when

tested with the device, its comparative NOx emissions increased.         The

probable reason for the NOx increase is the resulting leaner air/fuel ratio

as evident from the decrease in CO emissions, and the effect it had on the

performance of the three—way catalyst.         The comparative emissions of

Vehicle #2 were not adversely affected with the use of the device.            This,

possibly is due to the feed—back controls which compensate, within their

limit of authority, for the changes in air/fuel ratio caused by the device.

      Since it was found through this evaluation that the device adversely

affects some vehicles and does not affect others, the application of the

device was subsequently changed from the original request.   The revised

application requests that the Model B be used only on vehicles which have

compensating feed—back controls (like Vehicle #2) and ones not equipped

with TWC only (like Vehicle #1) while the Model C device be used on all

other vehicles.   _
      The Model C is a simple ol separator.    The oil separator portion of

the device has been appraised by staff not to reduce the effectiveness of

the PCY system and therefore does not cause an adverse emissions impact.

The applicant‘s claimed benefit for the device is to prevent engine oil
from reaching the cylinders and forming carbon deposits.

      During the Board‘s evaluation of the Model B device which accumulated

approximately 100 miles of use on each vehicle, the collectors were

inspected for oil deposits.   One vehicle was found to have a trace of oil

in the collector while the other had none.    There seems no short term

benefit of removing oil from tfie crankcase gases as apparent from the

comparative exhaust emissions or the fuel economy results.    It is not

known, however, from this evaluation if long term benefits could be

obtained with the device.
