  2. Variable valve timing - Wikipedia

    en.wikipedia.org/wiki/Variable_valve_timing

    Variable valve timing (VVT) is the process of altering the timing of a valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical ...

  3. Variable camshaft timing - Wikipedia

    en.wikipedia.org/wiki/Variable_camshaft_timing

    Right-hand side VCT oil control solenoid and harness from a Ford 4.6L SOHC 3V V8 engine. Variable camshaft timing (VCT) is an automobile variable valve timing technology developed by Ford. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts.

  4. Variator (variable valve timing) - Wikipedia

    en.wikipedia.org/wiki/Variator_(variable_valve...

    Variator (variable valve timing) Variable valve timing (VVT) is a system for varying the valve opening of an internal combustion engine. This allows the engine to deliver high power, but also to work tractably and efficiently at low power. [1] There are many systems for VVT, which involve changing either the relative timing, duration or opening ...

  5. VVT-i - Wikipedia

    en.wikipedia.org/wiki/VVT-i

    The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust ...

  6. Active valve control system - Wikipedia

    en.wikipedia.org/wiki/Active_valve_control_system

    The active valve control system (AVCS) is an automobile variable valve timing technology used by Subaru. It varies the timing of the valves by using hydraulic oil pressure to rotate the camshaft, known as "phasing", [1] in order to provide optimal valve timing for engine load conditions. The system is closed loop using the camshaft sensors ...

  7. Nissan VVL engine - Wikipedia

    en.wikipedia.org/wiki/Nissan_VVL_engine

    Nissan VVL engine. Nissan Ecology Oriented Variable Valve Lift and Timing (commonly known as VVL & VVT) is an automobile variable valve timing technology developed by Nissan. VVL varies the duration, and lift of valves by using hydraulic pressure switch between two different sets of camshaft lobes. VVT varies the valve timing throughout the RPM ...
