Abstract: A control system for an engine includes a variable valve timing device configured to selectively adjust opening and closing of an exhaust valve of the engine, a sensor configured to generate a signal indicative of a condition associated with pre-ignition of air and fuel in a cylinder of the engine, and a controller in communication with the variable valve timing device and the sensor. The controller is configured to control the variable valve timing device to selectively initiate a conventional valve timing or a quick-open valve timing based on the signal. In the quick-open valve timing the exhaust valve is moved from a closed position to a maximum lift position in a shorter amount of time than in the conventional valve timing.

CPC classification number: F02M26/43
Abstract: A multi-cylinder engine including a donor cylinder, a non-donor cylinder, at least one intake manifold, and at least one camshaft is provided. An intake valve of the donor cylinder controls a flow of air into the donor cylinder. The donor cylinder fluidly communicates exhaust gases to an exhaust gas recirculation (EGR) system. An intake valve of the non-donor cylinder controls a flow of air into the non-donor cylinder. The at least one camshaft controls an opening and closing of the intake valve of the non-donor cylinder such that the intake valve of the non-donor cylinder is maintained open for a first intake duration. The at least one camshaft controls an opening and closing of the intake valve of the donor cylinder such that the at least one intake valve of the donor cylinder is maintained open for a second intake duration which is greater than the first intake duration.

Abstract: An engine control system having quick-open valve timing is disclosed. The engine may have a cylinder, a piston slidably disposed in the cylinder, and an exhaust valve configured to open and close an exhaust port. Operation of the engine may include directing air and fuel into the cylinder, and combusting the air and fuel to force the piston between a TDC position and a BDC position. Operation may further include cyclically opening and closing the exhaust valve during piston movement according to a first valve timing. Operation may also include receiving a signal indicative of a condition associated with pre-ignition of the air and fuel, and selectively opening and closing the exhaust valve according to a second valve timing, based at least on the signal. In the second valve timing, the exhaust valve may be moved from a closed position to a maximum lift position in a shorter amount of time than in the first valve timing.
