Fuel regulation system for combustion engine with cylinder injection

摘要

The system contains an inlet air-flow sensor, a crank angle sensor, and a fuel injection arrangement installed in each cylinder of the combustion engine for a direct fuel injection. An exhaust fume feedback arrangement regulates a quantity of exhaust fume led back from an exhaust fume conductor to an inlet conductor. An electronic control arrangement determines control sizes for the fuel injection arrangement and the exhaust fume feedback arrangement. The system contains an inlet air-flow sensor for detecting an inlet air flow which is supplied to the combustion engine, and a crank angle sensor for detecting a rotational speed of the combustion engine and its crank angle. A fuel injection arrangement is installed in each cylinder of the combustion engine for a direct fuel injection. An exhaust fume feedback arrangement regulates the quantity of exhaust fume led back from an exhaust fume conductor of the combustion engine to an inlet conductor. An electronic control arrangement determines control sizes for the fuel injection arrangement and the exhaust fume feedback arrangement on the basis of the detected information.
