Abstract

PURPOSE:To prevent unstableness of an air-fuel ratio, in a system where an air control valve is provided on a passage which penetrates an intermediate housing and is communicated to the operating chamber of each cylinder, by providing a means by which opening operation of the air control valve is relaxed. CONSTITUTION:In a serial two cylinder rotary engine, a communicating passage 12 is formed in an intermediate housing 3 which is located between two rotor housings 2a and 2b, and in the position closed by rotors 6a, 6b a set value later than that for intake ports 7a, 7b opened on both side surfaces of the housing 3. And communicating state is repeated through this communicating passage 12 between the operating chamber during the compression process of a cylinder 5a (5b) and the operating chamber during intake process of the cylinder 5a (5b). In addition, an air flow control valve 13 is provided in the communicating passage 12, and it is opened/closed by a diaphragm type actuator 14 for responding to an intake pipe negative pressure, and a negative pressure delay valve 16 is interposed in the pressure leading passage toward a negative pressure chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION [0414] The present invention provides an output control leg sizing straightening 11-1-Kihan 1〈Kal type It relates to a rotary engine (y, below, simply referred to as rotary engine).

Conventionally, in terms of the power of the OH temple, there is no need for thermal engineering to generate energy. The meeting is lost as a loss of law, loss of machine capture, etc. (each loss of chain, etc.) Loss O
- Pump loss increases during the suction stroke.
When the pump J is lost, the abrasive load is more than 30% when the load is 1 high. The engine is better to improve fuel efficiency by arranging warehouses.

On the other hand, if the same vehicle has a smaller engine, the fuel efficiency will be better. One of the major reasons for this is that the engine is relatively expensive, so the loss of engine power is hft. Tsuchizu's engine, if you make a low-load engine with a low-stroke engine with a low-load engine and a low-load engine, you will be able to buy a high-load 11J) Ando Dekamono 114F. D4I/) Please think about improving the cost of grinding and twisting the pump J.

In other words, it is necessary to reduce the pump loss at low loads), and to prevent the loss of the throttle valve due to the suction pressure that freezes in the suction stroke and valve opening. Pass anus. This is true not only for eL-moving piston engines, but also for rotary piston engines, as well as N-type rotary engines.

'1 It's during the process of firing that the operating room begins to form a loaf or a loaf, and the process begins with the left lever, and it becomes an extremely small spade eating process, which leads to my warehouse. The load is relatively higher than that of the 9 engine. 6 strands of thread are used for the fire, and the pump loss is 1 h.

While I was trying to solve the problem, I got very excited, and it was written in Japanese Patent Application Laid-Open No. 63-25321. → Pass through the i passage on the left and move to the left.
The language is fixed, and then the valve is placed on the long axis of the trochoid, and the injection valve is closed and the loaf is closed. I'm b-t to the middle school 0 fraud ν2 burn) h?
