Abstract

PURPOSE:To reduce the consumption of fuel, by installing a pressure accumulation valve for delivering compressed air to an outside pressure accumulation chamber and by installing an exhaust gas suction valve for delivering exhaust gas to a working chamber. CONSTITUTION:A pressure accumulation valve 8 serves to deliver compressed air to an outer pressure accumulation chamber 10. An exhaust gas suction valve 9 serves to deliver exhaust gas to a working chamber. During the rotation of a rotor 2, air is sucked in through an inlet hole 6 and the pressure accumulation valve 8 is opened to deliver the compressed air to the pressure accumulation chamber 10. The exhaust gas suction valve 9 is then opened to deliver exhaust gas to a working chamber. At that time, an eccentric shaft 5 is turned as a result to take out the pressure of the exhaust gas as an output. Subsequently, the inlet hole 6 is opened to suck in a mixture and the pressure accumulation valve 8 is opened to deliver the compressed air from the pressure accumulation chamber 10 to the working chamber. Ignition is then caused by a spark plug 14 so that an expansion takes place. Since the output stroke is reduced by half and the air and the mixture are compressed in two stages, the consumption of fuel is diminished.

る。However, by compressing the room air and the air-fuel mixture in two stages to compensate for the resulting reduction in output, the average effective pressure is increased, and the combustion is completed and what was previously released into the atmosphere as exhaust gas is sent into the working chamber. The purpose of the present invention is to provide a method for improving a rotary engine by which the exhaust gas pressure can be taken out as output and compensate for the decreased output.

以下、作動原理を第３図を使用し、１つの作動室に注目

After this state, the intake hole is covered by the side of the rotor and closes, ending the intake. As the rotor rotates, the volume of the working chamber is gradually reduced as ■-■-〇-■, sending compression chamber air into the pressure accumulation chamber, and the pressure accumulation valve closes.

残りは排気吸入弁まで導かれる。The volume of the working chamber reaches its minimum at ■, and after ■, the exhaust intake valve opens and the exhaust gas is sent into the working chamber, which has sent compressed air into the pressure accumulation chamber, and the exhaust gas pressure applies pressure to the surface of the rotor. ■-〇-O and exhaust gas pressure continue to apply pressure to the rotor surface and the exhaust intake valve closes with O. At this time, the eccentric shaft is rotated, and the exhaust gas pressure can be extracted as output. ■Opens the exhaust hole provided around the rotor housing■－＠－

When the intake hole opens after ①, the intake of the air-fuel mixture begins, and as the rotor rotates, the intake hole provided on the side wall of the side housing gradually opens wider and sucks in the air-fuel mixture, and at the same time the working chamber opens. -■-〇The volume increases and becomes maximum at O.

Then, the air-fuel mixture is gradually reduced in size, and when the air-fuel mixture is compressed to zero, the spark is emitted by the ignition cylinder and the air-fuel mixture is ignited. The air-fuel mixture ignited in the state of ■ increases in volume and pressure as it burns, and continues to expand as follows.The combustion energy applies pressure to the surface of the rotor, causing the eccentric shaft to rotate. This is the shaft output. ■
As the volume of the working chamber decreases, the exhaust holes installed around the rotor housing open and some of the air is released into the atmosphere.
The rest is led to the exhaust intake valve.

It can also be used as a compression ignition engine because it can increase the average effective pressure.
