Abstract

PURPOSE:To prevent firing of an ignition plug or deterioration of catalyst, by increasing the amount of air through a valve provided in an air-bleede path upon cut of fuel supply while reducing or stopping lubricant thus reducing consumption of lubricant. CONSTITUTION:During deceleration or reduced cylinder operation of engine, fuel supply is cut while a valve 25 is functioned to open thus to open an air- bleed path 24. Air-bleed is fed to the lubricant feed paths 20, 21 to reduce or stop supply of lubricant to be injected through nozzles 22, 23. Since combustion is not performed because of cut of fuel supply, consumption of lubricant can be reduced by the amount corresponding to the amount of lubricant to be consumed through combustion. Consequently, firing of ignition plugs 10, 11 can be suppressed while deterioration of catalyst can be prevented.

(Structure of the Invention) In order to achieve the above object, the technical solution of the present invention is to supply the lubricating oil from the metering oil pump to the working chamber through the lubricating oil supply passage, and at the same time, during a specific operation of the engine. In the rotary piston engine, which covers the supply of fuel 1181 to the working chamber, the air bleed passage that supplies bleed air is joined to the lubricating oil supply passage, and the air bleed passage that supplies bleed air is opened and closed to the soil ablation passage. In addition to installing a valve c), a control device is installed to control the operation of the valve c) in the opening direction so that the amount of air bleed from the air bleed passage increases when the fuel supply is stopped. As a result, when the fuel supply is cut, the supply of lubricating oil is reduced or stopped due to the air bleed amount (19'Jff) due to the opening operation of the inter-open valve, so that excess lubricating oil is removed from the working chamber. It was designed to eliminate the supply of

Therefore, according to the present invention, a rotary piston engine that reduces the supply of fuel to the working chamber during specific operations such as when the engine is decelerating or when the engine is running without cylinders.
5, when the fuel supply is cut, the supply of lubricating oil to the working chamber is reduced to 100% or more, so it is possible to reduce the amount of lubricating oil consumed by supplying excess lubricating oil. At the same time, it is possible to prevent the ignition plug from smoldering, and if the exhaust passage is equipped with a catalyst device, it is possible to prevent the deterioration of the catalyst.Furthermore, the lubricating oil supply control described above can be controlled by -L. Since it is performed by increasing/decreasing control at the abride level, it also has the advantage that the viscosity can be well controlled.

It should be noted that the present invention (not limited to the embodiment described in j1),
It also includes various other modifications. For example,
As shown by the imaginary line in Fig. 1, ■ Abbreviation passage 2/l
A bypass passage 34 that bypasses the on-off valve 25 is provided (in comparison with the bypass passage 3/I, a bypass passage 35 is provided to J3,
Even during normal operation, the throttle 35 is
1. Bleed air for the specified purpose measured by 1. Second
Lubricant "oil supply j'1120, 2+ to supply it properly ri1
lubricating oil 4--to the working chamber 6, and on the other hand, a specific luck II+/, lli? that reduces the fuel supply. Between the on-off valve 25 ('+ movement, the above-mentioned bypass passage 34
In addition, bleed air may also be supplied from the soil azolead passage 24 to increase the amount of air bleed, thereby reducing or stopping the supply of lubricating oil to the working chamber 6. Further, the on-off valve 25 is interposed in either the '1st or the second branch passage 248.24b of the king abduct passage 24, and the on-off valve 25 is controlled to open and close according to the operating state. good.

J. In the above embodiment, two lubricating oil supply passages 20, 21, the first and second, are provided, and the low-load intake passage 12 is provided from the '1d3 and the second oil supply nozzles 22, 23, respectively.
The type that supplies lubricating oil to the working chamber 6 through a or directly has been described above, but only from either one! I
It goes without saying that this method can also be applied to types that supply lubricating oil.
