  2. Valve timing - Wikipedia

    en.wikipedia.org/wiki/Valve_timing

    With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers ...

  3. VarioCam - Wikipedia

    en.wikipedia.org/wiki/VarioCam

    VarioCam is an automobile variable valve timing technology developed by Porsche. VarioCam varies the timing of the intake valves by adjusting the tension on the timing chain connecting the intake and exhaust camshafts. VarioCam was first used on the 1992 3.0 L engine in the Porsche 968.

    en.wikipedia.org/wiki/Toyota_S_engine

    The third-generation engine uses the Toyota C20b turbo, which was of the same design as the second-generation but with a slightly improved turbine housing and larger compressor wheel. A factory BPV is installed on all applications. The intake charge is cooled by a water-to-air top-mounted intercooler similar in shape to the ST185RC WTA.

  5. Variable valve timing - Wikipedia

    A possible downside to early intake valve closing is that it significantly lowers the temperature of the combustion chamber, which can increase hydrocarbon emissions. [3] Early intake valve opening Early intake valve opening is another variation that has significant potential to reduce emissions. In a traditional engine, a process called valve ...

  7. Four-stroke engine - Wikipedia

    en.wikipedia.org/wiki/Four-stroke_engine

    Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.

  9. Stroke (engine) - Wikipedia

    en.wikipedia.org/wiki/Stroke_(engine)

    The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine.It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.
