System and method for the control of an internal combustion engine

A valve control system (3 Fig. 1) controls a valve 30 located in a flow path between an ancillary inlet 25 of an intake manifold 18 and a crankcase 15 of an internal combustion engine 10. The system has a controller which receives a request signal that a vehicle operation condition has been met. The controller then sends a first control signal to the valve and restricts flow through the flow path. The vehicle operation conditions can include engine shut-down, engine start-up, engine overrun, eco-stop and engine shut-down preparation. The first control signal may cause the valve 30 to close, and an engine throttle 19 may also close either in response to the first signal or a second signal from the controller. A request that an engine condition has been met for engine shutdown can cause the throttle, which is located in a flow path between the air intake 16 and the intake manifold, to close and to stop the fuel supply to the engine. The valve control system may form part of a vehicle control ...

INTERNAL COMBUSTION ENGINE WITH PURGING OF CYLINDER CASING

Recirculation valve

In a recirculation valve, a first support target portion receives a biasing force of a biasing member on a first stepped surface and moves to one side in an axial direction, such that a first opening is blocked. The first support target portion moves to the other side in the axial direction against a biasing force of the biasing member due to a negative pressure on a downstream side with respect to an upstream side, such that the first opening opens.

Engine equipped with breather mechanism

Breather mechanism includes a breather passage opening into a crankcase, a breather chamber communicating with the crankcase via the breather passage, and a valve provided in the breather chamber and openable to allow blow-by gas to flow from the crankcase into the breather chamber once inner pressure of the crankcase exceeds a predetermined value. When the engine is placed in a laterally laid-down position, entry, into the breather chamber, of lubricating oil is prevented by the breather passage. When the engine is placed in a vertically upright position, an outlet end portion of the breather passage is located above an inlet end portion of the breather passage.

Methods and apparatuses for missing filter detection and prevention in rotating coalescer designs

Systems and methods for detecting a missing coalescing element in a CV system are described. In some arrangements, the described systems and methods prevent the assembly and/or re-assembly of the CV system without an appropriate coalescing element positioned within the CV system housing (e.g., during a coalescing element service operation).
