SUMMARY Turbo International, of 7091A Beigrave Avenue, Garden Grove, California 92641 has applied for exemption from the prohibitions in Vehicle Code Section 27156 of their add—on turbocharger kit number 45000. The kit is intended for installation on the following General Motors Corporation vehicles powered by a 454 CID engine: 1. 1978 through 1983 model—year heavy—duty vehicles (G¥W over 8,500 Tbs). 2. 1977 and older model—year heavy—duty vehicle (GVW over 6,000 Ibs). 3. 1978 and 1979 model—year medium—duty vehicles (GYW of 6,001 through 8,500 Tbs). Emission test results submitted by Turbo International and generated by the ARB test facility indicate that the add—on turbocharger kit number 45000 will not significantly affect emissions from vehicles for which exemption is requested. Based on the above, the staff recommends that Turbo International be granted an exemption as requested and that Executive Order D—112—2 be granted.

INTRODUCTION Turbo International, of 7091A Belgrave Avenue, Garden Grove, California 92641 has applied for exemption from the prohibitions in Vehicle Code Section 27156 of their add—on turbocharger kit number 45000. The kit is intended for installation on the following General Motors Corporation vehicles powered by a 454 CID engine: 1. 1978 through 1983 model—year heavy—duty vehicles (G¥W over $,500 1bs). 2. 1977 and older model—year heavy—duty vehicle (GYW over 6,000 1bs). 3. 1978 and 1979 model—year medium—duty vehicies (GVW of 6,001 through 8,500 Tbs). Turbo International has submitted data from back—to—back emission tests conducted on a 1982 General Motors Corporation heavy—duty Sferra pick—up truck at Custom Engineering Performance and Emissions Laboratory in Garden Grove, California. Confirmatory tests were conducted on the same vehicle at the Air Resources Board (ARB) laboratory in E1 Monte, California. II. CONCLUSION Emission test results submitted by Turbo International and generated by the ARB test facility indicate that the add—on turbocharger kit number 45000 will not significantly affect emissions from vehicles for which exemption is requested.

III. RECOMMENDATIONS Based on the above conclusion, the staff recommends that Turbo International be granted an exemption as requested and that Executive Order D—112=2 be granted. IV. TURBOCHARGER KIT DESCRIPTION AND OPERATION The purpose of turbocharging an engine is to increase its volumetric efficiency by forcing more air into an engine than it would take in under naturally aspirated conditions. The major components of the Turbo International kit are a Rajay turbocharger model number E10 (now manufactured by Rotomaster) with an A/R ratio of 1.0, a replacement exhaust manifold (right bank), a crossover pipe, an EGR vaIve, replacement primary and secondary metering rods, a carburetor—to—intake manifold adapter box, and a water injection system. The components are packaged with installation hardware and instructions and sold as a kit. The crossover pipe routes exhaust from the left cylinder bank (driver‘s side) to join the right cylinder bank at the Turbo International replacement manifold. The turbine inlet of the turbocharger mounts directly to the exhaust manifold. Intake air/fuel mixture, taken from the carburetor, is compressed by the compressor and returned to the intake manifold through the carburetor—to—intake manifold adapter box. The original primary and secondary metering rods in the carburetor are replaced by metering rods #52P and #AX, respectively. Turbo International, who supplies the replacement metering rods, claims that the new rods increases fuel delivery for proper and efficient operation of the kit. Turbo International also claims that the additional secondary fuel will suppress detonation during power demand operations. — 2 —

Water injection is employed to suppress detonation. Water is piped from a small plastic reservoir through a solenoid to the adapter box. The solencid is activated by a signal from a pressure sensor located on the adaptor box at the compressor outlet. When 1 psig of pressure is sensed, the solencid injects water into the adapter box, ahead of the turbocharger, through a 0.042 inch orifice. Maximum positive manifold pressure is lTimited to 7 psig by the size of the compressor inlet. No wastegate or other active boost limiting device is used. An EGR vaive is mounted on the engine to control NOx exhaust emissions. The EGR valve, part number PF7041427, is furnished by Turbo International to be mounted on the intake manifold {right hand side). The vacuum lHine from the EGR valve is connected to the vacuum/thermo switch located at front, top of the vehicles water pump. Vacuum signal to the vacuum/thermo switch is obtained from ported vacuum source at the carburetor. No modifications to the vehicle manufacturer‘s tune—up specifications are required when the turbocharger kit is installed. All OEM emission controls, including the air injection to BOTH exhaust banks, are left intact. V. TURBOCHARGER KIT EVALUATION A 1982 General Motors Corporation heavy—duty Sferra pick—up truck powered by a 454 CID engine was used for the evaluation of the turbocharger kit. A description of the vehicle and test parameters is given in the Appendices. Evaluation consisted of comparative (without and with the kit installed on the test vehicle) cold—start CVS-75 and hot—start Highway Fuel Economy tests for measuring exhaust emissions and fuel economy. Tests were performed under contract by Custom Engineering for Turbo International and confirmed by the ARB Taboratory.

A synopsis of the test data is tabulated in the Appendices. V. BISCUSSION Heavy~duty engines are emissions tested for certification on engine dynamometers. Because exhaust emission tests on engine dynamometer are more time consuming and cumbersome than chassis dynamometer tests, it was decided that chassis dynamometer exhaust emission tests would be more practical for evaluating the effects the add—on turbocharger would have on emissions. The original design installation instructions of the turbocharger kit recommended that the vehicle‘s carburetor be retained unmodified and the air injection to the right bank be disconnected. As a result, HC and CO exhaust emissions were adversely affected during the cold transient phase of the CYS—75 emisstons test. Driveability problems (stalls and poor acceleration) were a1s§ noted during cold engine operations. In order to improve cold driveability and reduce emissons (to be comparable with baseline emissions), Turbo International installed different primary and secondary metering rods and reinstalled the right bank air injection tubes,. According to Turbo International, the replacement metering rods will increase the fuel delivery and improve driveability. They also claim that reinstalling the air injection, at the right bank, will reduce HC exhaust emissions. The emissions results with these modifications are shown in the tables (Appendices) and superscripted with (2).
