Problems solved by technology
[0002] At present, the continuously variable valve timing mechanism of the known piston internal combustion engine can only control the opening and closing time of the intake and exhaust valves by changing the timing of the intake and exhaust valve camshafts, but cannot control the intake and exhaust valves from opening to closing. duration and valve lift
This limits the further improvement of the effective power and thermal efficiency of the internal combustion engine, the reduction of fuel consumption and the improvement of pollutant emission performance through the continuously variable valve timing system

A piston type internal combustion engine with continuously variable valve timing valve mechanism features the main inlet camshaft and sub inlet camshaft simultaneously controlling air inlet air valve start-stop and start-stop duration and valve stroke through compensated bogie. Said invention not only can continuously change air valve timing to control air inlet / outlet valve start-stop time, change but also air inlet / outlet valve start-stop time duration and valve stroke, thereby further raising internal combustion engine effective power.
Description
Technical field [0001] A continuously variable valve timing valve mechanism piston type internal combustion engine, especially a continuously variable valve timing valve mechanism piston type internal combustion engine which continuously changes the opening and closing, duration and valve lift of intake and exhaust valves. Background technique [0002] At present, the continuously variable valve timing mechanism of the known piston internal combustion engine can only control the opening and closing time of the intake and exhaust valves by changing the timing of the intake and exhaust valve camshafts, but cannot control the intake and exhaust valves from opening to closing. duration and valve lift. Thereby limiting the further improvement of the effective power and thermal efficiency of the internal combustion engine through the continuously variable valve timing system, the reduction of fuel consumption and the improvement of pollutant emission performance.
