Abstract

The invention provides an ultrahigh-pressure air inlet oxygen-enriched combustion two-stroke internal combustion engine, and relates to the technical field of internal combustion engines. Comprising a plurality of internal combustion engine bodies, each internal combustion engine body comprises a cylinder, a piston, a cylinder cover, a crankshaft and a piston lower space, and a sensor is arranged on a crankshaft output shaft; a spark plug, an oil sprayer, a high-pressure air inlet and an exhaust valve are arranged on the cylinder cover, the exhaust valve is externally connected with an exhaust manifold through an exhaust pipe, and an outlet of the exhaust manifold is connected with the turbine side of the waste gas turbine; a pressure reducing valve and a pressurizing valve are arranged on two sides of the lower space of the piston, the pressure reducing valve is externally connected with an air outlet header pipe through an air outlet pipe, and the pressurizing valve is externally connected with an air inlet header pipe through an air inlet pipe; the gas outlet header pipe and the gas inlet header pipe are connected with a suction inlet and an exhaust outlet in the gas compression side of the waste gas turbine. High-pressure air is directly sprayed into the air cylinder through the high-pressure air inlet, and the internal combustion engine can have higher power density without compression work; through a waste gas turbine structure, exhaust energy of the air cylinder is converted into piston motion kinetic energy for acting, and the power of the internal combustion engine is increased.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an ultra-high pressure intake air oxygen-enriched combustion two-stroke internal combustion engine. Background technique [0002] In recent years, the aggravation of environmental protection issues and the relative shortage of petroleum resources have caused various relevant departments to invest more energy in the development and utilization of new energy, the improvement of power plants, and the formulation of stricter regulations to achieve the effective use of resources and discharge pollutants. decrease. At present, the internal combustion engine is still the most important power machinery, and the ship power system, some power generation systems and automobile power systems are still dominated by engines. [0003] Due to the structural principle, the loss of fresh gas is large during the ventilation process of the two-stroke engine, and the exhaust gas ...
