A hydrogen engine using fuel gas containing hydrogen, including: a cylinder; a piston movable within the cylinder; a cylinder head forming a combustion chamber with the piston, and including an intake port connected to the combustion chamber and a fuel sup...

A variable valve timing apparatus, and internal combustion engine incorporating the same, that allows the timing of the opening and/or closing of intake and/or exhaust cylinder valves to be altered relative to a reference timing. As a result, the timing of...

In a dual fuel engine using the FCT technology, a new FCT configuration of an FCT shaft (42) is used to allow transitioning between a liquid fuel mode and a gaseous fuel mode at higher engine loads. According to the new configuration, a liquid fuel main in...

The device has a tilt lever (2) connected on one side via a valve actuating bridge (4) to a delay device (E) and on the other directly to a play compensating telescopic device (T) on a push rod (1). The delay device has a cylindrical bush (Z) on the actuat...

An exhaust gas reflux apparatus for an internal combustion engine (E) includes one-way connection means (26) provided between an intake rocker arm (14i) and an exhaust rocker arm (14e). The one-way connection means moves between a non-operating position (A...

The system has a cam assembly to move an intake valve (32) between two positions to stop and to allow a flow of fluid, respectively. A fluid actuator stops the valve from moving to one of the positions. A directional control valve is placed between a sourc...
