| Abstract: | Engine using variable valve timing technology can improve the intake charge,so that coefficient of charge increase,engine torque and power can be further improved.This paper analyzes the Honda VTEC engine's variable valve timing technology,developed a modular timing camshaft.This modular flexibility to change the cam outside the contour length,started to change the valve timing and valve openings at the maximum duration,can be used to improve the effectiveness of the engine valve. |
