 Pursuant to the authority vested in the undersigned by Sections 39515 and
 39516 of the Health and Safety Code and Executive Order G—45—5;

 IT IS ORDERED AND RESOLYED:     That the installation of the Preheat. Duct Tube
 Kit device manufactured by Custom Products Speed and Marine has been found

                                  summary


        Custom Products Speed and Marine of 27933 Adon Avenue, Canyon

Country, CA 91351, submitted an application for exemption from the

 prohibitions in Section 27156 of the California Vehicle Code for the

bcompany's Preheat Duct Tube Kit device.    The applicant has requested that

exemption be granted for the installation of this device on all 1974 and

older model—year vehicles originally equipped with a heated air intake

system and retrofitted with exhaust headers.    This device is intended to

replace the function of the original equipment manufacturer‘s (OEM) hot

air duct and stove when the OEM exhaust manifold is replaced by exhaust

headers,

       The staff evaluated the device and found that the Preheat Duct

Tube Kit device will not have a significant adverse effect on emissions

from 1974 and older mode1-yeaf vehicles retrofitted with exhaust headers.

       The staff, therefore, recommended that the ARB issue Executive

Order D—149, allowing the installation of the Preheat Duct Tube Kit

device on all 1974 and older model—year vehicles originally equipped with

a heated air intake system retrofitted with exhaust headers.

EVALUATION OF CUSTOM PRODUCTS SPEED AND MARINE‘S PREKEAT DUCT TUBE KIT
DEVICE FOR EXEMPTION FROM THE PROHIBITIONS IN VEKICLE CODE SECTION 27156
IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA
ADMINISTRATIVE CODE


1.    INTRODUCTION

      Custom Products Speed and Marine of 27933 Adon Avenue, Canyon

Country, CA 91351, submitted an application for exemption from the

prohibitions in Section 27156 of the California Vehicle Code for the

company‘s "Preheat Duct Tube Kit" device.   Vehicle Code Section 27156

prohibits the installation of any device or mechanism which reduces the

effectiveness of required emission control systems on any California

certified vehicle.   This code also authorizes the Air Resources Board

(ARB) to exempt a device from the prohibitions if it‘can be demonstrated

that the device, upon installation on the engine, will not adversely

affect the performance of existing emission control systems.   The

applicant has requested that the exemption be granted for the installation

of this device on all vehicles requiring heated air supply system.

II.   CONCLUSION

      The staff evaluated the device and found that the "Preheat Duct Tube
Kit" device will not have a significant adverse effect on emissions from

the vehicles originally equipped with a heated air intake system which was

connected to the OEM exhaust manifold.


III.   RECOMMENDATION

       Based upon engineering evaluation made on a sample device, sales

brochure and technical data submitted by the applicant, the staff recommends

that the ARB exempt the "Preheat Duct Tube Kit" device from the prohibitions

of Vehicle Code §ection 27156 and that Executive Order D—149 be issued,

allowing the installation of "Preheat Duct Tube Kit" device on all 1974 and

‘earlier model—year vehicles retrofitted with exhaust headers and originally

equipped with a heated air intake system which was connected to the OEM

exhaust manifold.

IV.    SYSTEM DESCRIPTION

       The Preheat Preheat Duct Tube Kit device consists of a fabricated heat

box, two mounting stainless steel clamps, and a 17—in. long light aluminum

flex tubing, with its diameter properly selected to match the air cleaner‘s

original stove pipe attachment.   The heat box, which is the heart of this kit,

was formed (Figure 2 of Appendix A ) from 1/32 inch thick sheet metal.     It

measures 7/8 inch high, 2 inches wide and 3—1/2 inches long.     A 1—1/2 inch

diameter by 7/8 inch long, 3/32 inch wall thickness steel tube is welded at

the center of the heat box to accommodate one end of the aluminum flex tubing;

the other end of the tubing is connected to the air cleaner.     The heat box is

fastened on one of the header pipes.   Air in the engine compartment is drawn

into the air cleaner through a 2.38 square inches opening* between the heat

box and the header pipe during cold engine starting operation.




*See the air flow area calculation on Appendix D, pp. 8—9.


          This device was designed to duplicate the function of the OEM system to

 enhance the formation of a homogeneous fue]-air mixture in its gaseous state

 and to hasten the combustion process during cold engine starting operation.

 ¥.       DISCUSSION

          The ambient air from the engine compartment is conveyed through the heat

 box, flex tubing, and air cleaner to the carburetor where it is mixed with the

 fuel.    This air/fuel mixture then goes into the intake manifold and is

 distributed to each cylinder.     The minimum cross—sectional flow area of this

 device is 2.38 square inches compared to the OEM‘s 1—1/2 square inches.        The

 air passing through the heat box gains heat by conduction, convection and

 radiation from the surfaces of hot engine parts including the exhaust header

 pipes.     The temperature of the inlet air to the engine during engine cold

 starting operation is anticipated to be equal or higher than that with the OEM

 heat riser system.    The use of the device for maintaining good cold start

 engine performance, therefore, does not seem to have any adverse effect on

 exhaust emissions from 1974 and older vehicles retrofitted with exhaust

'headers.

  Dear Mr. Crispin de la Cruz,

  We mounted a stock T.A.C. type air cleaner from a 350 C.I.D.
  chevrolet on a superflow flow bench, through inlet nozzel we
  took a baseline reading at 1 1/2" water and flow rate 100 C.F.M.,
  then with vacuum pump actuated the T.A.C. value to simulate
  cold start mode:           Results through stock 350 C.I.D. manifold with
  preheat stove (factory unit)               the flow at 1        1/2" water was 30 C.F.M.
  we also tested flow at 5" water flow 52 C.F.M.. Our preheat ducts
  tube kit installed on same air cleaner and as instalied on head—
  ers at   1       1/2" water flow 35 C.F.M., at 5" water flow 63 C.FP.M..
