Engine with central axis elliptical rotor and compressed air bridged fuel oil clamped injection

Abstract

The invention discloses an engine with central axis elliptical rotor and compressed air bridged fuel oil clamped injection, and relates to a central axis elliptical rotor engine device. The engine is characterized in that: four travels, namely air inlet, compression, work doing and exhaust are simultaneously alternately finished in spaces with periodically changed volume, and two-time work doing travels are finished when a rotor rotates a circle. The engine has the advantages that: 1, a mode that high-temperature high-pressure compressed air performs fuel oil clamped injection replaces a novel combustion mode that premixed gas is subjected to compression ignition, so that the problem of high oil consumption is solved, and the fuel adaptability of the engine is improved; 2, a fixed displacement pump supplies fuel oil according to the actual condition, so that high-efficiency combustion work doing with a variable air-fuel ratio can be realized; 3, a central axis elliptical rotor replaces an eccentric axis triangular rotor, so that the processing cost of parts is reduced while stability is improved; and 4, contact surfaces of two ends of the elliptical rotor and the inner wall of a cylinder are lubricated and sealed by a roller, and sliding friction is changed into rolling friction, so that system loss and operating cost are effectively reduced.

Description

technical field [0001] The invention relates to a central axis elliptical rotor engine device, which is characterized in that the four strokes of air intake, compression, sitting power, and exhaust are respectively completed alternately in a space where the volume changes periodically, and the elliptical rotor completes two times of work when it rotates once. journey. Background technique [0002] At present, the four strokes of the traditional piston engine are completed sequentially in the same space. Its structure is complex, large in size and heavy in weight. The four strokes of the "eccentric shaft triangular rotor engine" invented by Dr. Wankel in Germany are continuous in three spaces. It has the characteristics of simple structure, small size and light weight. The triangular rotor engine developed by Japan Mazda has 1. It can only compress the pre-mixed gas of air and fuel, and the compression ratio is not high. 2. High fuel consumption and high operating costs. 3. ...
