方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for improving a rotary engine, in which the output stroke is halved and an accumulator valve and an exhaust intake valve are installed.
従来のローターが１回転する間に３回の出力行
程であつたものを、半分の、ローター２回転に対
し３回の出力行程にし、燃費軽減を図る。 The conventional rotor takes 3 power strokes per revolution, but this is halved to 3 power strokes per 2 rotor revolutions to reduce fuel consumption.

ー・エンジンの改良方法を提供する目的である。 However, by compressing the air and air-fuel mixture in two stages, the resulting reduction in power output is increased to increase the average effective pressure, and what was previously released into the atmosphere as exhaust gas after combustion is sent into the working chamber. The object of the present invention is to provide a method for improving a rotary engine in which the exhaust gas pressure can be taken out as output and compensate for the decreased output.

へ放散され、残りは排気吸入弁まで導かれる。 When the working chamber is at the position, the rotor rotates, the intake hole opens, and air begins to be taken in. As the rotor rotates, the intake hole provided on the side wall of the side housing gradually opens wider and sucks in air. At the same time, the volume of the working chamber increases to -, which reaches its maximum and opens the accumulator valve, and when the state of - is passed, the intake hole is covered by the side of the rotor and closed.
Finish inhaling. As the rotor rotates, the volume of the working chamber is gradually reduced, compressed air is sent into the accumulator chamber, and the accumulator valve is closed.
The volume of the working chamber becomes minimum at , and after ,
The exhaust intake valve opens, the exhaust gas is pumped into the working chamber which pumped compressed air into the accumulator chamber, the exhaust gas pressure applies pressure to the surface of the rotor, and the exhaust gas pressure applies pressure to the surface of the rotor. Then the exhaust intake valve closes. At this time, eccentric
Rotating the shaft reduces exhaust gas pressure,
It can be extracted as output. The exhaust hole provided around the rotor housing opens.
-- and as the volume of the working chamber decreases,
Exhausted. This means that the rotor has rotated once. When the intake hole opens, the air-fuel mixture begins to be taken in. As the rotor rotates, the air-fuel mixture opens gradually, and as the rotor rotates, the intake hole on the side wall of the side housing gradually opens wider and sucks in the air-fuel mixture. At the same time, the working chamber... The volume increases and becomes maximum at 〓〓. When the state of 〓〓 is passed, the intake hole is covered by the side of the rotor and closed, and after the intake of the air-fuel mixture is finished, the volume of the working chamber is gradually reduced, and the pressure accumulating valve is opened to send the pressurized air into the working chamber. Increase the average effective pressure. As the rotor rotates, the volume of the working chamber gradually decreases as follows: 〓〓－〓〓－〓〓－〓 ignite. The air-fuel mixture ignited in the state of 〓〓 increases its volume and pressure as it burns, and continues to expand as 〓〓-〓〓-, and the combustion energy applies pressure to the surface of the rotor, causing the eccentric shaft to rotate. This results in shaft output. At 〓〓, the exhaust hole provided around the rotor housing opens, and as the volume of the working chamber decreases, some of it is dissipated into the atmosphere, and the rest is It is led to the exhaust intake valve.
この時の排気ガスがを過ぎた時に作動室に送

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