摘要： A combustion engine comprises a suction valve system for discharging blow-by gas from the crankcase into an air inlet channel for the cylinders. The suction valve system is driven by an electromotor which is connected to a power source. The system comprises a rev counter which measures the rpm of the suction valve system, as well as a control unit which is connected to the power source, the rev counter and the engine management system. The control unit can set predefined engine conditions as well as the power flowing to the suction valve system to have this system rotate at a predefined speed. The value of the set power is a measurement for the blow-by.In lieu of regulating the power flowing to the suction valve system, the control unit can also set the power flowing to the suction valve system to a predefined value. The rev counter then measures the rpm of the suction valve system, which is a measurement for the blow-by.

摘要： Methods and systems are provided for flowing crankcase gases through an aspirator arranged in a PCV line. The aspirator regulates PCV flow, and may also generate vacuum depending on a position of a pintle extendable across a horizontal passage of the aspirator. When regulating PCV flow and not generating vacuum, the aspirator is fully closed and crankcase gases in the horizontal passage are metered through an orifice in the pintle. When generating vacuum, the aspirator is at least partially opened and PCV flow through the horizontal passage generates vacuum at a vacuum port of the aspirator.

摘要： A control system for an engine includes first and second modules. The first module determines an oxygen concentration within an intake manifold of the engine. The second module regulates a flow of exhaust gas recirculation (EGR) into the intake manifold based on the determined oxygen concentration. In a homogeneous charge compression ignition (HCCI) engine, the second module may also disable an HCCI combustion mode of the HCCI engine based on the oxygen concentration.

摘要： In a breather device for engine, in which an inlet of a breather chamber communicates with a crank chamber through a reed valve, the reed valve being formed of: a fixed stopper plate arranged so as to be opposed to a valve seat formed on an end face of the inlet facing the breather chamber; and an elastic valve plate fixed at one end thereof to the stopper plate and capable of bending elastically to change its position from a closed position in which the elastic valve plate closes the inlet by seating on the valve seat to an opening limit position in which the elastic valve plate opens the inlet and abuts against the stopper plate, the stopper plate is provided at a center part thereof with an oil discharge hole through which oil present between the elastic valve plate and the stopper plate is pushed out when the elastic valve plate is pushed toward the opening limit position in which the elastic valve plate abuts against the stopper plate by pressure in the crank chamber. Accordingly, it is possible to prevent the elastic valve plate from sticking to the stopper plate even if oil mist adheres to the elastic valve plate or the stopper plate of the reed valve.
