||An evaluation was initiated of the Ford stratified charge engine, using as the test vehicle, an Army M-151 1/4 ton truck equipped with a four wheel drive system with the front wheel drive portion controlled by the driver. The engine, a 141 CID four cylinder with a 3 inch bore and 3 7/8 inch stroke, is the 'low emission' version of the Ford stratified charge combustion system. Ford's basic stratified charge system uses an unthrottled air intake with fuel injected directly into the cylinder. Descriptions are given of the modifications made to the control systems to provide low emissions. The emission performance of the test vehicle was evaluated by using the 1975 LA4-S4 test cycle. Test results are discussed and tabulated.
