Overview
VVT-i replaces the previous VVT system and varies the timing of the intake valves to improve engine efficiency. The technology has been widely adopted by various brands, including Toyota, Lexus, Scion, Daihatsu, Subaru, Aston Martin, Pontiac, and Lotus Cars. The VVT-i system works by applying engine oil pressure to an actuator to adjust the camshaft position. The system is controlled by the engine's computer, which monitors various parameters such as engine speed, load, and temperature to optimize the valve timing. The technology has been used in various racing applications, including the 24 Hours of Le Mans. The development of VVT-i was a collaborative effort between Toyota's engineering teams and its partners, including Denso and Aisin.
🎵 Origins & History
The concept of intelligent intake was first introduced with the launch of the 2JZ-GE engine in the Toyota Crown and Crown Majesta. This technology replaced the previous VVT system, varying the timing of the intake valves by adjusting the relationship between the camshaft drive and intake camshaft, resulting in improved engine efficiency.
⚙️ How It Works
The VVT-i system works by applying engine oil pressure to an actuator to adjust the camshaft position. This adjustment in the overlap time between the exhaust valve closing and intake valve opening results in improved engine efficiency. The system is controlled by the engine's computer, which monitors various parameters such as engine speed, load, and temperature to optimize the valve timing. For example, Honda has also developed its own version of variable valve timing, known as VTEC, which has been used in various Honda models, including the Civic and Accord.
