Advantages and disadvantages of CVVT engines
The CVVT engine is English Continue Variable Valve Timing acronym, translated into Chinese is continuously variable valve timing mechanism of engine, it is one of the many variable valve in recent years has been gradually applied in the modern car is in a. The engine from low speed to high speed conversion, the computer will automatically be machine oil to the intake camshaft driving gear inside the small turbine, under pressure, small turbine rotating a certain angle gear relative to the shell, so that the camshaft in the range of 60 degrees forward or backward rotation, thereby changing the inlet valve the opening moments, to achieve the purpose of continuous valve timing adjustment.
The utility model has the advantages that the opening and closing of the valve can be controlled according to the actual working condition of the engine, and the fuel can be burnt more fully, so as to enhance the power and reduce the oil consumption
Disadvantages: only control valve timing, there is no control valve lift function. Therefore, the engine will only change the suction and exhaust time difference, can not change the intake.
