Abstract: A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing extending in a horizontal plane and having an upper planar horizontal surface, a lower planar horizontal surface, and side surfaces extending between the upper and lower surfaces. A planar horizontal flat panel filter element extends parallel to the upper and lower surfaces. The housing has an upper plenum between the flat panel filter element and the upper surface, and a lower plenum between the flat panel filter element and the lower surface, an inlet receiving oil and air from the diesel engine and supplying same along an inlet path to the upper plenum to flow downwardly through the flat panel filter element to the lower plenum, a first outlet outputting air along a first outlet path from the lower plenum, and a second outlet outputting oil along a second outlet path from the lower plenum.

Abstract: A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing having an inlet receiving oil and air from the diesel engine, an outlet returning air to the engine, a drain returning separated oil to the engine, and a flat panel filter element in the housing receiving the oil and air from the inlet, separating the oil from the air, and passing the air to the outlet and passing the oil to the drain.

Abstract: The present invention provides a knock sensing system for an internal combustion engine which utilizes only a single knock sensor associated with one of the engine cylinders. Operation of the engine is controlled such that the cylinder which is equipped with a knock sensor will be the first cylinder to experience combustion knock as compared to the remaining engine cylinders. This can be done by various methods, such as advancing the ignition timing on the designated cylinder. The knock sensor is then monitored by the engine control module in order to sense premature detonation on the designated cylinder, knowing that it is highly unlikely that knocking will occur on the other engine cylinders if knocking is not occurring on the designated cylinder. When knocking is sensed, appropriate action, such as shutting down the engine, may be taken by the engine control module. The knock sensor is preferably mounted to a capscrew which couples the intake manifold to the cylinder head.

Abstract: A vented, unitary sealing grommet for establishing a first liquid-tight interface between a ignition coil and a spark plug adapter tube and a second liquid-tight interface between the ignition coil and a valve cover includes a hollow main body portion having a substantially cylindrical shape with a longitudinal axis and including a pair of annular sealing ribs, a planar flange portion which is disposed within a geometric plane which is substantially perpendicular to the longitudinal axis, the main body portion being designed to fit between the ignition coil and the spark plug adapter tube such that the annular sealing ribs are compressed due to the interference fit. The planar flange portion is designed to fit between ignition coil and the valve cover.

Abstract: The lip of the combustion bowl of a piston for an internal combustion engine has different radii in different sections of the bowl. Most of the lip is sharp to reduce emissions. The part of the lip above the piston pin bore is less sharp to reduce the mechanical stresses that otherwise would accumulate there in a sharp lip, cracking the piston. The lip has a smooth transition between the two radii to avoid creating additional stress.

Abstract: The present invention provides a very simple structure to delay high fuel delivery to a turbocharged engine until a sufficient turbocharger boost pressure is available for adequate combustion, by providing a simple dashpot to limit movement of the throttle shaft. A brea-away throttle lever is used so that the operator can position the control lever at any position, even though the position of the throttle shaft itself is being limited by the dashpot. Preferably, the damping structure is entirely housed within the fuel injector pump, where it will be safe from debris, and constantly flushed with clean fuel.
