ABSTRACT:
A vehicular powertrain includes a conventional gasoline internal combustion engine, a continuously variable ratio transmission, and a feedback control system and engine speed sensor for regulating the power produced by the engine to a value selected by the vehicle operator. The feedback control system operates the engine at wide open throttle and a lean burn air-fuel ratio over a wide range of operating conditions of the vehicle, with the control system adjusting the transmission ratio to regulate the engine speed to a value corresponding to the power selected by the operator. As a result of the extensive engine operation at wide open throttle and a lean burn air-fuel ratio, exhaust emissions are held to a low level while fuel economy is significantly increased.
