Description
ロータリーエンジンを搭載した自動車や2輪車、電車、飛行機船舶等の乗り物や発電機、ポンプ、コンプレッサーなど。Vehicles such as automobiles, motorcycles, trains, airplane ships, etc. equipped with rotary engines, generators, pumps, compressors, etc.
近年、益々自動車のエンジンは小型化、高出力化、低燃費が求められ、エンジンの高効率化が求められている。In recent years, more and more automobile engines are required to have smaller size, higher output, and lower fuel consumption, and higher efficiency of the engine is required.
ロータリーエンジンは4サイクルエンジンと比較して小型高出力と言う特徴を持つが、燃費が悪いと言う欠点を持つ。エンジンの冷却を高めてエンジンの温度を低くすると線膨張係数によって混合気が収縮するため、混合気の圧縮工程で圧力が低下し、ポンピングロスが下がるが、混合気が爆発して膨張するときにロータリーエンジンのハウジングに熱を奪われて爆発後の燃焼ガスの温度が低下し、ロータリーエンジンの燃焼室の圧力が低下し、ローターを押す力が低下してエンジン出力が低下する。つまり冷却ロスが大きくなり、出力や燃費が低下し、実行効率が低下する。本発明はロータリーエンジンのハウジングの温度の制御によって実行効率の高いロータリーエンジンを提供する。A rotary engine has a feature of small size and high output as compared with a four-cycle engine, but has a disadvantage of poor fuel consumption. Increasing engine cooling and lowering engine temperature causes the air-fuel mixture to contract due to the coefficient of linear expansion, which reduces the pressure during the air-fuel compression process and reduces pumping loss. The heat of the rotary engine is deprived of heat, the temperature of the combustion gas after the explosion decreases, the pressure of the combustion chamber of the rotary engine decreases, the force pushing the rotor decreases, and the engine output decreases. That is, the cooling loss increases, the output and fuel consumption decrease, and the execution efficiency decreases. The present invention provides a rotary engine with high execution efficiency by controlling the temperature of the housing of the rotary engine.
4サイクルエンジンは同一シリンダー内で混合気を圧縮し燃焼してピストンを押し下げてエンジン出力が発生する。しかしロータリーエンジンは混合気の圧縮室と燃焼室が分かれているため、ロータリーエンジンの圧縮室の部分はハウジングのウォータージャケットに冷却水を流して冷却して混合気の圧力を下げてポンピングロスを低下させ、燃焼室の部分はハウジングのウォータージャケットに排気ガスを流して排気熱で燃焼室を加熱し、燃焼室内の燃焼ガスの温度低下を抑制することによって燃焼室内の冷却損失による圧力低下を抑制して高いエンジン出力が得られる。The 4-cycle engine compresses and burns the air-fuel mixture in the same cylinder and pushes down the piston to generate engine output. However, since the rotary engine has a separate compression chamber and combustion chamber, the compression chamber portion of the rotary engine is cooled by flowing cooling water through the water jacket of the housing to lower the pressure of the mixture and lower the pumping loss. The combustion chamber part controls the pressure drop due to the cooling loss in the combustion chamber by flowing the exhaust gas through the water jacket of the housing and heating the combustion chamber with exhaust heat to suppress the temperature drop of the combustion gas in the combustion chamber. High engine output.
ロータリーエンジンの実行効率が向上し、燃費とエンジン出力向上を同時に改善でき、4サイクルエンジンよりも小型高出力、低燃費エンジンが得られる。The execution efficiency of the rotary engine is improved, and the fuel efficiency and the engine output can be improved at the same time. A compact, high output and low fuel consumption engine can be obtained compared to the 4-cycle engine.
