摘要：Self-adaptive hydraulic variable valve timing system for an internal combustion

diesel engine, comprising an electronic control unit, an oil pump, a pressure regulatingreversing valve, an oil return tube, an oil line, an oil supply main tube, an oil supply branchtube, and a self-adaptive pushrod length changing assembly. When the engine's oilexceeds 70° C., and engine's rotational speed is greater than or equal to 1300 r/m, andengine's load is greater than or equal to 50%, the control unit is configured to sendinstructions to the pressure regulating reversing valve to switch oil flow directiontowards the oil line which leads to the self-adaptive pushrod length changing assemblyand thereby put the engine in an operating mode.
