摘要： The present invention involves a system and method of compensating sensor error of a differential pressure sensor on an exhaust gas recirculation passage for a calculation of a flow rate of recirculated exhaust gas into a vehicle engine. The method includes providing data representing default output of the differential pressure sensor based the coolant temperature of the engine and providing a predetermined threshold deviation of the default output. The method further includes determining the engine coolant temperature and an actual idle output of the sensor, when the engine is at an idle engine speed for a predetermined period of time, and calculating an actual error value of the sensor based on observing the actual idle output and engine coolant temperature. The method further includes utilizing the actual error of value of calculating the flow rate of the recirculated exhaust gas into the vehicle engine at off-idle conditions.

摘要： A method for engine start-up reducing white smoke and the start-to-idle time. The method includes the combination of producing two sub-fuel injections into the cylinders of the internal combustion engine at different points in the position of at least one injection valve of the engine and reducing the number of combusting cylinders in half. The two sub-fuel injections reduce the start-to-idle time. Once the engine is idling, the half cylinder operation reduces the white smoke emitted therefrom. The two sub-fuel injections are also employed when in half cylinder operation to reduce noise.
