An evaluation was conducted on an Army M-151 1/4 ton truck, which had minor modifications made to the emission control system. The Army M-151 is tested with an inertia weight of 3,000 lbs. Calculated from the actual weight of the vehicle. The engine used in these tests was a 141 CID four cylinder with 3 inch bore and 3 7/8 inch stroke, developed by the Ford Motor Company. In order to provide low emissions from this engine, several modifications were made in the control systems. A very close control over fuel air ration was required, therefore, an air throttle system was developed to provide a 17:1 air-fuel ratio. Exhaust gas recirculation was added to reduce the amount of oxides of nitrogen. This engine was provided with a thermal reactor. The air-fuel ratio control was an experimental unit and did not contain an ambient pressure compensator.
