| Abstract: | A new developed electrical control VVT system is presented which uses a tensioner with variable working position to change the intake valve-closing angle. It has many advantages such as its simple structure, less modification to engine and low cost etc. The test results show that the engine performance improved distinctly, especially in respects of torque at low speed, the power at high speed, the fuel economy and the emission in some working conditions. This VVT system is suitable for high-speed automotive gasoline engines with DOHC. |
