摘要： A variable valve system for an internal combustion engine includes a drive shaft rotated by an engine crankshaft, a drive cam integrally mounted on the drive shaft, first and second swing cams mounted on first and second engine valves in each engine cylinder, a valve lift mechanism for converting a rotational movement of the drive cam into swing movements of the first and second swing cams to open and close the first and second engine valves, and a control mechanism for controlling the operating position of the valve lift mechanism to vary the valve lifts of the first and second engine valves according to engine operating conditions. The valve lifts of the first and second engine valves are different from each other when the control mechanism performs minimum lift control on the valve lift mechanism to control the valve lifts of the first and second engine valves to minimum lifts.

摘要： A ‘Blackburn Cycle’ or 8 stroke and 4 stroke cycle change piston engine has a separate fuel/air inlet duct and valve in a cylinder where the throttle means admits a small volume, namely less than 10% of the cylinder capacity, needed for a low idling speed. A separate ‘air only’ inlet duct and valve admits alternate ‘air only’ inductions in each cylinder when less than half load is needed. The preferred plug type of throttle can be disc or cone shaped or shaped to substantially fill the volume between the closed throttle and the inlet valve seat. For higher power the throttle moves away from the inlet valve to open the inlet port. Fuel is injected into the small volume between the throttle and the inlet valve where engine heat helps vaporize the fuel without heating a large mass of the inlet air.

摘要： The invention relates to a method for controlling the opening and closing of the intake valves of an internal combustion engine with a direct fuel injection system, comprising at least one first intake valve and a second intake valve per cylinder, wherein each valve respectively opening or closing a first and second intake duct per cylinder can be controlled independently of the other valve, wherein at least one of the ducts is supplied with fuel and at least one of the other ducts is not supplied with fuel. According to the invention, said method consists in controlling the valve or valves corresponding to the intake ducts supplied with fuel during the time intervals when the injection system does not function. The invention also relates to a system for the application of said method.

摘要： An exhaust gas recirculation (EGR) system for use in a four-stroke, internal combustion, compression-ignition engine having at least one engine cylinder, at east one combustion chamber, at least one intake valve and a crankshaft. The EGR system includes at least one exhaust gas intake valve that is opened during at least a portion of an engine intake stroke when the exhaust gas pressure is greater than the pressure of gas in the combustion chamber, thus allowing exhaust gas to flow into the combustion chamber to establish internal EGR. A cam-operated intake rocker arm assembly has the form of both a first class lever and a second class lever. The first class lever directly communicates motion of the intake rocker arm assembly to open the intake valve, and the second class lever communicates motion of the intake rocker arm assembly through a hydraulic transfer assembly to open the exhaust gas intake valve.
