EVALUATION OF J. BITTLE AMERICAN, INC. 1.5 ROLLER ROCKER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION « J. Bittle American, Inc. (JBA) of 9630 Aero Dr., San Diego, California 92123, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their 1.7 Roller Rocker, part nos. 2341, 2343, 2321, and 2331 for installation on 1992 and older Ford Motor Company vehicles. JBA has submitted a completed application and all the required information, as well as exhaust emissions test data performed at Crane Emissions Laboratory. II. CONCLUSIONS ‘ Based on the submitted information and results of the emission tests performed at Crane Emissions Laboratory, the staff concludes that the J. Bittle American, Inc. 1.7 Roller Rocker will not adversely affect exhaust efiisaions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that J. Bittle American, Inc. be granted an exemption as requested and that Executive Order D—216—7 be issued. IV. 1.7 ROLLER ROCKER DESCRIP:ION( The JBA 1.7 Roller Rocker is designed to increase the rocker arm ratio of the small block Ford V—8 gasoline engines with 289 to 351 CID engine sizes from a 1.6:1 to 1.7:1. The 1.7 Roller Rocker operates in conjunction with the original equipment manufacturer‘s (OEM) emission control systems already certified with the stock engines. The purpose of using the modified 1.7 Roller Rocker is to increase the overall engine performance by modifying the valve characteristics.

v. BISCUSSION OF THE 1.7 ROLLER ROCKER JBA submitted emission testing conducted at Crane Emissions Laboratory. A 1991 Ford Mustang powered by a 302 CID engine was used as the test vehicle for the 1.7 Roller Rocker. The dynamometer inertia weight and loading used during the testing were 3625 lbs. and 7.7 hp; respectiyely. Emissions testing consisted of one cold—start CVS—75 Federal Test Procedure in the modified configurations evaluated against the vehicle‘s emission standards. The test results are shown in Table 1. Table 1 CVs—75 TEST RESULTS (Crane Emissions Laboratory) Test Exhaust Emissions (gm/mi) Mode BC co NOx Standard 0.41 3.4 1.0 1.7 Roller Rocker | 0.19 1.95 0.41 Difference ~0.22 —1.45 —0.59 The CVS—75 emissions test results at Crane Emissions Laboratory indicate that HC, CO and NOx emissions of the 1.7 Roller Rocker are below the emission standards for that vehicle. The test results do demonstrate that the installation of the 1.7 Roller Rocker for all 1992 and older Ford Motor Company vehicles powered by a 289 to 351 CID V—8 gasoline engines will —2—

not adversely affect the exhaust emissions. Results were not confirmed by the ARB; however, the test results are consistent with previous testing conducted on similar rocker arms with increased ratio of 1.7. JBA has submitted all the required information and fulfilled the requirements for an exemption. The test resuits and engineering evaluation confirmed that JBA 1.7 Roller Rocker, part nos. 2341, 2343, 2321, and 2331 meet the requirements for the exemption.
