Abstract: The present invention discloses a prechamber jet disturbance intensified combustion system, comprising a main combustion chamber and a main fuel injector, the lower end of a fuel nozzle of the main fuel injector is located inside the main combustion chamber; a plurality of prechambers are arranged outside the main combustion chamber, the prechambers are connected with the main combustion chamber by prechamber channels, an auxiliary fuel injector is arranged outside each prechamber, and the lower end of a fuel nozzle of the auxiliary fuel injector is located inside the corresponding prechamber. The present invention abandons layout and combustion process idea of an existing heavy-duty diesel engine combustion system, which remarkably increases the mixing rate of fuel and air and the combustion rate by using autonomous and controllable parts, materials and process conditions.

Abstract: Self-adaptive hydraulic variable valve timing system for an internal combustion diesel engine, comprising an electronic control unit, an oil pump, a pressure regulating reversing valve, an oil return tube, an oil line, an oil supply main tube, an oil supply branch tube, and a self-adaptive pushrod length changing assembly. When the engine's oil exceeds 70° C., and engine's rotational speed is greater than or equal to 1300 r/m, and engine's load is greater than or equal to 50%, the control unit is configured to send instructions to the pressure regulating reversing valve to switch oil flow direction towards the oil line which leads to the self-adaptive pushrod length changing assembly and thereby put the engine in an operating mode.
