 This Executive Order is granted based on results from ecissions tests
 conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
 However, the ARB finds that reasonable grounds exist for believing that use
 of some components of the kit may adversely affect emissions of motor
 vehicles when operating under conditions outside the parameters of the
 previously prescribed test procedures.  Accordingly, the ARB reserves the
 right to conduct additional emission tests, in the future, as such tests are
 developed, that will more adequately measure emissions from all cycle
 phases.   If such test results demonstrate that the Turbocharger Kit
 adversely affects emissions during off—cycle conditions {defined as those
 conditions which are beyond the parameters of the Cold—Start CVS—75 Federal
 Test Procedure), this Executive Order shall be effectively rescinded as of
 the date the test results are validated.  Further, if such test results or
 other evidence provides the ARB with reason to suspect that the Turbocharger
 Kit will affect the durability of the emission control system, Dinan
 Engineering,   Inc.   shall be required to submit durability data to show that
 the durability of the vehicle emission control system is not, in fact,
 affected and/or that the add—on or modified part demonstrates adequate
 durability.

 In addition to the foregoing, the ARB reserves the right in the future to
 review this Executive Order and the exemption provided Lerein to assure that
 the exempted add—on or modified part continues to meet the standards and
 procedures of Title 13, California Code of Regulations section 2222 et seq.
 and any future amendments thereto.

I.      INTRODUCTION

        Dinan Engineering,    Inc.   (Dinan) of 81 Pioneer Way, Mountain View,

California 94041 has applied for an exemption from the prohibitions in

Vehicle Code Sections 27156 and 38391 for their Turbocharger Kit part

numbers D800—7500, D8O0—8500, and D800—8502 for installation on the

foliowing model—year BMW 5.0L vehicles:

D800—8502      1991—1992             8501                Manual

The Dinan Turbocharger Kit consists of Warner/Ishi turbocharger model

RHBS2/5T—503, new larger capacity Bosch Motronic electronic fuel injection,

Turbotronics III Prom, Turbotronics V electronic fuel enrichment computer,

new smaller air cleaner, new intake plumbing, air—to—air intercooler, new

PCV tubing, new evaporative canister for BMW 750iL only,      an electronic

ignition control computer, Turbotronics III ECU ignition prom, new exhaust

manifold, and new head pipes.

II.     CONCLUSION

        Results from tests conducted at Milton Roy Company in Orange,

California, showed that emissions from the test vehicle did not exceed

California‘s new vehicle certification standards with the Dinan‘s

Turbocharger Kit installed.     Due to time constraints, the Air Resources

Board (ARB) could not perform confirmatory testing on the test vehicle.

Based on the low emission levels from the independent laboratory testing,

staff concludes that the installation of fhe Dinan‘s Turbocharger Kit will

not reduce the effectiveness of the emission control systems of the

applicable vehicles.


This conclusion is also based on the available test cycles under the Federal

Test Procedure.

III.      RECOMMENDATION

          The staff recommends that the exemption be granted as requested and

that Executive Order No. D—176—3 be issued, permitting the advertisement,

sale and installation of the Turbocharger Kit on vehicles shown above.

Iv.       DEVICE DESCRIPTION

          The purpose of the Dinan turbocharger kit is to increase the power

output of the 5.0L BMW engine by compressing the intake air charge to a

pressure above that of the atmosphere,     and thereby increasing the volumetric

efficiency of the engine.      This is accomplished by using exhaust gas to spin

a turbine which in turn spins a compressor.     Compression of the intake air

increases its charge density providing more oxygen for combustion.      The

increased air flow requires more fuel in order to maintain the proper

air/fuel ratio for optimum combustion.      In order to better manage the demand

for extra fuel, Dinan uses larger capacity fuel injectors; Turbotronics III,

a modified electronic control unit (ECU) prom program to re—curve the fuel

injection and ignition systems; and Turbotronics V, an electronic fuel

enrichment computer to provide proper fuel delivery under boost conditions.

          The Warner/Ishi turbocharger used by Dinan in their kit is of the

radial flow type with area ratio (A/R) of 0.59; area of throat of 2.46

square inches; and distance from centroid area to center of vortex of 2.75

inches.    The turbocharger achieves a maximum boost pressure of 10 psi with

the stock engine‘s 9:1 compression ratio.


        Other modifications to the vehicle‘s emission control system are:

(1) Replacement of stock air cleaner with smaller air cleaner due to space

limitation,    (2) Installation of new intake plumbing to accommodate the

intercooler,    (3)   Installation of an air—to—air intercooler between the

turbocharger and intake manifold to reduce the intake charge temperature,

(4} Re—routing the PCV to a new location to prevent exposure to boost

pressure,   (5) Replacing the evaporative canister in 750iL BMW with another

canister of the same storage capacity and relocating it using new hoses with

the appropriate length,      (6) An electronic ignition control computer and a

new detonation sensor are used to prevent detonation,      (7) A modified ECU

prom program (Turbotronics III) is used to re—curve the ignition system to

match the requirements of the turbocharged engine,      (8) Installation of new

exhaust manifolds, and (9)     Installation of new head pipes.

v.      DEVICE EVALUATION

        The aéplicant has submitted test results conducted at Milton Roy

Company, an independent test laboratory,     in Orange, California.   One CVS—75

test was conducted on a 1990 BMW 750iL powered by a 5.0L engine.      All BMW

models included in the application have the same emission standards and are

equipped with the same emission control system as the test vehicle.

        According to the literature submitted by Dinan, the turbocharger

boost begins at engine speed of 1600 RPM.      In order to determine if the

turbocharger would cause any adverse effect on the emissions control system

during boost, the test vehicle was driven for twenty miles to bring it to

full operating temperature.      Following the mileage accumulation, a steady—>

state test similar to the Smog Check was conducted at 2500 RPM.


Emissions from both tests were compared with new vehicle certification

standard and the Smog Check standard for the test vehicle model—year.

                               CVS—75 Test Results

Due to time constraints, the ARB could not perform confirmatory testing with

the Dinan Turbocharger Kit.        The exemption of the Turbocharger Kit is

therefore based on the test results from Milton Roy Company which showed

that the device did not produce any adverse effect on the test vehicle.
