Abstract: A system for mounting an engine to a frame in a manner to permit measurement of its torque by a transducer which is isolated from loads induced by installation misalignments, frame deflections and acceleration induced forces. One embodiment of the system is compatible with widely used automotive resilient elastic engine mounts without engine or frame modifications.

Abstract: In a closed loop fuel management system for an internal combustion engine, a gas sensor is positioned in the intake manifold and is responsive to a characteristic of the fuel mixture for generating an electrical control signal for controlling the metering of the fuel to the mixture. In the preferred embodiment, the air and fuel are mixed together and the resultant mixture passes by an oxygen gas sensor prior to being distributed to the cylinders through the intake manifold system. The output signal of the sensor is used for controlling the metering of the fuel. Fuel delivery correction delays due to transport lag in conventional closed loop fuel management systems using oxygen gas sensors are eliminated.

Abstract: In a fuel injection system for an internal combustion engine, a gas sensor is positioned in the intake manifold and is responsive to a characteristic of the air mixture entering the intake manifold to generate electrical control signals for controlling the injecting of the fuel to the engine. In the preferred embodiment, the air and the recirculated exhaust gas (EGR) are mixed together in a throttle body and the resultant mixture passes by the gas sensor prior to being distributed throughout the manifold system. The output signal of the sensor is used in controlling the injection time of the fuel injectors. Fuel delivery correction delays due to transport lag in conventional closed loop fuel injection systems using oxygen gas sensors placed in the exhaust system are greatly minimized.
