Implementations
- Alfa Romeo - Double continuous variable valve timing. CVVT is used on inlet and exhaust valves.
- BMW - Double VANOS.
- BMW/PSA Peugeot Citroën - Continuous variable valve timing (CVVT)
- Chrysler - dual Variable Valve Timing (dual VVT). Used on Chrysler GEMA "World" engine.
- Daihatsu - Dynamic variable valve timing (DVVT)
- Ford - Variable valve timing (VVT)
- General Motors - Variable valve timing (VVT) provides continuous variable valve timing.
- Geely - Continuous variable valve timing (CVVT)
- Kia - Continuous variable valve timing (CVVT)
- Honda - The i-VTEC system uses VTC (Variable Timing Control) to provide continuous timing variation of the intake camshaft on DOHC i-VTEC engines. On the VTEC-E engines, an SOHC 3 valve, an oil pressure actuated solenoid activated when certain conditions are met and the second of the two intake valves opens and closes with the first.
- Hyundai - Continuous variable valve timing (CVVT) - provides continuous variable valve timing on Intake, Fuel System and Exhaust all independently controlled
- Mazda - S-VT - The ECU calculates intake timing and actuates an oil control valve to modulate oil pressure.
- Mitsubishi - MIVEC system for the 4B1 engine family - intake and exhaust cam timing is continuously and independently controlled
- MG Rover - Variable Valve Control (VVC)
- Nissan - Continuous Variable Valve Timing Control System (CVTCS). The ECU adjusts the engine's timing continuously to prevent detonation/pinging and optimize gas mileage.
- Porsche - VarioCam and VarioCam Plus.
- Proton (carmaker) - Cam Profile Switching (CPS).
- Toyota - Variable Valve Timing with intelligence (VVT-i), Variable Valve Timing with Lift and Intelligence (VVTL-i).
- Volvo - Continuous variable valve timing (CVVT)
