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.

発明が解決しようとする課題Problems to be solved by the invention

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.

課題を解決するための手段Means for solving the problem

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.

発明の効果Effect of the invention

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.

本発明のロータリーエンジンの断面概念図である。１はハウジング、２はローター、３はエキセントリックシャフト、４はスパークプラグ、５は排気ポート、６は吸気ポート、７は燃焼室、８は圧縮室、９は加熱ジャケット、１０は水冷ジャケットである。１のハウジングの中の壁に沿って反時計回りにローター２が回転し、ローター２が自転しながら公転することによってエキセントリックシャフト３が反時計回りに回転し、外部に動力を出力する。ローターの回転によって圧縮室８の体積が拡大するときに吸気ポート６から混合気が入り、次に燃焼室の体積が狭くなるとともに混合気が圧縮され、混合気の体積が小さくなって高圧になった時にスパークプラグ４が点火し、混合気が燃焼する。混合気が燃焼して高温になることによって圧力が上昇し、燃焼室７の体積が膨張しながらローター２が進角し、ローター２のギアを反してエキセントリックシャフト３に回転力が伝わる。そして燃焼室の体積が収縮するときに排気ポート５から燃焼ガスが排出され、また吸気ポート６から次の混合気の吸気が始まる。圧縮室８を冷却するため、１０の水冷ジャケットに外部の空気によって冷やされた流体が流れる。一方、燃焼室７の温度を高温に保つため、加熱ジャケット９に排気熱によって加熱した流体が流れる。It is a section conceptual diagram of the rotary engine of the present invention. 1 is a housing, 2 is a rotor, 3 is an eccentric shaft, 4 is a spark plug, 5 is an exhaust port, 6 is an intake port, 7 is a combustion chamber, 8 is a compression chamber, 9 is a heating jacket, and 10 is a water cooling jacket. The rotor 2 rotates counterclockwise along the wall in the housing 1, and the eccentric shaft 3 rotates counterclockwise as the rotor 2 revolves while rotating to output power to the outside. When the volume of the compression chamber 8 expands due to the rotation of the rotor, the air-fuel mixture enters from the intake port 6, and then the volume of the combustion chamber decreases and the air-fuel mixture is compressed. The spark plug 4 ignites and the air-fuel mixture burns. When the air-fuel mixture burns and becomes high temperature, the pressure rises, the volume of the combustion chamber 7 expands, the rotor 2 advances, and the rotational force is transmitted to the eccentric shaft 3 against the rotor 2 gear. When the volume of the combustion chamber contracts, the combustion gas is discharged from the exhaust port 5 and the intake of the next air-fuel mixture starts from the intake port 6. In order to cool the compression chamber 8, a fluid cooled by external air flows through 10 water cooling jackets. On the other hand, in order to keep the temperature of the combustion chamber 7 at a high temperature, the fluid heated by the exhaust heat flows through the heating jacket 9.
