摘要： A method for energy ignition management of a spark-ignition engine includes receiving, by a controller, at least one ignition energy characteristic to affect control of at least one combustion cylinder. The method further includes controlling the at least one combustion cylinder via the controller. Controlling the at least one combustion cylinder via the controller includes adjusting the at least one ignition energy characteristic in response to at least one operating condition of the engine. The at least one ignition energy characteristic is a magnitude of one of a current or voltage of spark energy.

摘要： The invention relates to a method for controlling an exhaust gas recirculation circuit for an internal combustion engine of a motor vehicle. The engine is linked to an air intake circuit and to a gas exhaust circuit linked to the air intake circuit by the recirculation circuit. A first valve controls the flow of air upstream from the recirculation circuit, and a second valve controls the flow of exhaust gases that are recirculated within the recirculation circuit. The method comprises the following steps: a) the first valve is closed, and the second valve is gradually opened; b) if the second valve is opened at an angle greater than a value between 25° and 35°, the first valve is gradually opened concomitantly to the opening of the second valve. As a result of the invention, the EGR rate is easily controllable.

摘要： An engine includes an EGR apparatus which refluxes a portion of exhaust gas from an exhaust manifold to an intake manifold as EGR gas. A differential pressure sensor detects a differential pressure between intake pressure of the intake manifold and exhaust pressure in the exhaust manifold. The differential pressure sensor is mounted on a head cover which covers an upper portion of a cylinder head. An intake pressure taking-out passage which is in communication with the intake manifold is formed in the cylinder head. An intake pressure introducing passage which is connected to the differential pressure sensor is formed in the head cover. The intake pressure taking-out passage and the intake pressure introducing passage are in communication with each other.
