In the compression process, the valve opening at the bottom dead center and closing before the top dead center is related to the opening / closing state of the passage to the empty space {the above, 6 What is a cycle gasoline engine? [A 6-cycle engine consisting of a diesel engine and a gasoline engine (Japanese Patent Application No. 417964). The rotary valve is a six-cycle gasoline engine according to

In the compression process, the air-fuel mixture is less likely to be exhausted from the valve a. Therefore, during the compression process, at a low rotation, or at a low rotation, a medium rotation, a medium load In addition, the amount of the real air-fuel mixture in the cylinder can be increased at the time of high rotation and high load.

しかし、ここで言う発明は、開閉装置の型、は関係がなく、弁aの通路bを、低回転時、又は、低負荷時よりも、中回転時、又は、中負荷時、さらに、高回転時、又は高負荷時に、多く閉じる事である。 However, the invention referred to here has nothing to do with the type of the opening / closing device, and the passage b of the valve a is set at a higher speed at a middle speed or at a middle load than at a low speed or at a low load. Close during rotation or high load.
また、ピストンバルブを用いた6サイクルガソリンエンジンの、横断面図、縦断面図は描かれていないが、ピストンバルブを用いた4サイクルガソリンエンジンと、開閉装置の動きは同じなので、ここでは省く。 Also, although a cross-sectional view and a vertical cross-sectional view of a 6-cycle gasoline engine using a piston valve are not drawn, the movement of the switchgear is the same as that of a 4-cycle gasoline engine using a piston valve, so it is omitted here.
そして、ピストンバルブを用いた6サイクルガソリンエンジンの、2回目の吸気工程の時の弁も、ピストンバルブを用いた4サイクルガソリンエンジンに、空気専用の吸気弁を付け加えれば、ピストンバルブを用いた6サイクルガソリンエンジンの、横断面図、縦断面図が描ける。 And the valve at the time of the 2nd intake process of the 6-cycle gasoline engine using the piston valve is the same as that of the 4-cycle gasoline engine using the piston valve. A cross sectional view and a longitudinal sectional view of a cycle gasoline engine can be drawn.
さらに、弁aを、圧縮工程の時に開け過きた時の対策として、膨張工程の時、膨張し過ぎて回転の抵抗になる(膨張工程の時、膨張し過ぎてシリンダー内の気圧が1以下になり、クランク・シャフトを回転させる事の抵抗になる事。)前に開き、下死点で閉じる弁は、ピストンバルブを用いた4サイクルガソリンエンジン、ピストンバルブを用いた6サイクルガソリンエンジンに、該弁を付け加えれば、横断面図、縦断面図が描ける。 Further, as a countermeasure when the valve a is opened excessively during the compression process, the valve a is excessively expanded during the expansion process and becomes resistance to rotation (at the expansion process, the pressure in the cylinder is reduced to 1 or less. The valve that opens before and closes at bottom dead center is applied to 4-cycle gasoline engines using piston valves and 6-cycle gasoline engines using piston valves. If a valve is added, a transverse sectional view and a longitudinal sectional view can be drawn.
また、弁aの通路bを、エンジンの爆発回転数が、低回転時には閉じず、中回転時、高回転時と、回転数に因って、閉じる量を多くする事は、ロータリーバルブを用いた4サイクルガソリンエンジン、ロータリーバルブを用いた6サイクルガソリンエンジンにも、応用ができる。 In addition, the passage b of the valve a is not closed when the engine explosion speed is low, and it is necessary to increase the amount of closing depending on the number of revolutions, such as medium speed and high speed. It can also be applied to conventional 4-cycle gasoline engines and 6-cycle gasoline engines using rotary valves.
また、弁aの通路bを、エンジンの爆発回転に対しての抵抗が、低負荷時には閉じず、中負荷時、高負荷時と、負荷の量に因って、閉じる量を多くする事は、ロータリーバルブを用いた4サイクルガソリンエンジン、ロータリーバルブを用いた6サイクルガソリンエンジンにも、応用ができる。 In addition, the passage b of the valve a is not closed when the engine is rotated at a low load, and the amount of closing is increased depending on the amount of load, such as a middle load and a high load. It can also be applied to a 4-cycle gasoline engine using a rotary valve and a 6-cycle gasoline engine using a rotary valve.
さらに、ピストンバルブを用いた6サイクルガソリンエンジン、ロータリーバルブを用いた6サイクルガソリンエンジンの、2回目の吸気工程の時の弁(空気専用の吸気弁)、2回目の吸気工程の時の吸気口(空気専用の吸気口)は、膨張工程の時、膨張し過ぎて回転の抵抗になる前に開き、下死点で閉じる弁、気口と兼用できる(気口を兼用すると言うのは、同じロータリーバルブの気口を使用するのではなく、同じ物質を吸気するので、同じロータリーバルブに、2つの気口を設ける事である。)。 Furthermore, a 6-cycle gasoline engine using a piston valve, a 6-cycle gasoline engine using a rotary valve, a valve at the time of the second intake process (air intake valve), and an intake port at the time of the second intake process (Air intake port) can be used as a valve or air port that closes at the bottom dead center and closes at the bottom dead center. Instead of using the mouth of the rotary valve, the same substance is inhaled, so there are two mouths on the same rotary valve.)
本発明は、以上説明した様に構成されているので、以下に記載される様な効果を奏する。 Since the present invention is configured as described above, the following effects can be obtained.
弁aの通路bを、エンジンの爆発回転数が、低回転時には閉じず、中回転時、高回転時と、回転数に因って、閉じる量を多くする事に因り、圧縮工程の時、筒内にある本当の混合気の量が、低回転時よりも、中回転時、さらに、高回転時の方が多くなり、低回転時には、燃焼効率重視、中回転時、さらに、高回転時には、パワー重視のエンジンができる。 The passage b of the valve a is not closed when the engine explosion speed is low, but during the compression process, due to the increase in the amount of closing, depending on the rotation speed, during the middle speed and high speed, The amount of the actual air-fuel mixture in the cylinder is higher at medium speed and at high speed than at low speed. At low speed, combustion efficiency is important. At medium speed and at high speed A power-oriented engine can be created.
また、弁aの通路bを、エンジンの爆発回転に対しての抵抗が、低負荷時には閉じず、中負荷時、高負荷時と、負荷の量に因って、閉じる量を多くする事に因り、圧縮工程の時、筒内にある本当の混合気の量が、低負荷時よりも、中負荷時、さらに、高負荷時の方が多くなり、低負荷時には、燃焼効率重視、中負荷時、さらに、高負荷時には、パワー重視のエンジンができる。 Further, the passage b of the valve a is not closed when the engine is rotated at low load, but the amount of closing is increased depending on the amount of load at the time of medium load and high load. Therefore, during the compression process, the amount of the actual air-fuel mixture in the cylinder is higher at medium load and at high load than at low load. At the time of high load, you can create an engine that emphasizes power.
そして、動力にはならないが、低回転時には、燃焼効率重視、と言う事は、低回転時には燃料の消費が少なく、燃料の消費が少ないと言う事は、低回転時には、低公害につながる And, although it does not become power, it means that combustion efficiency is important at low revolutions, meaning that fuel consumption is low at low revolutions, and that fuel consumption is low, which leads to low pollution at low revolutions.
さらに、動力にはならないが、低負荷時には、燃焼効率重視、と言う事は、低負荷時には燃料の消費が少なく、燃料の消費が少ないと言う事は、低負荷時には、低公害につながる。 Furthermore, although it does not serve as power, the importance of combustion efficiency at low loads means that fuel consumption is low at low loads, and that fuel consumption is low leads to low pollution at low loads.
また、動力にはならないが、低回転時、又は、低負荷時には、燃焼効率重視、と言う事は、低回転時、又は、低負荷時には燃料の消費が少なく、燃料の消費か少ないと言う事は、低回転時、又は、低負荷時には、省資源、省エネルギーにつながる。 In addition, although it does not become power, it means that combustion efficiency is important at low revolutions or low loads, which means that fuel consumption is low and fuel consumption is low at low revolutions or low loads. This leads to resource saving and energy saving during low rotation or low load.
