JPS5882016A - Internal-combustion engine having parting plate in combustion chamber - Google Patents

Abstract

PURPOSE:To turn the internal-combustion engine stably at low speed by dividing the combustion chamber into two by the easily slidable parting plate, introducing air into one chamber and fuel into the other one during a suction stroke, and injecting fuel or air into the other one through a bypass during an expansion stroke. CONSTITUTION:In the suction stroke, a fuel induction valve 7 and an air induction valve 5 are opened during the falling of a piston 10, and gassy fuel and air are each sucked to the upper and lower air chambers of the parting plate 1 at a theoretical air-fuel ratio. In a compression stroke, all valves are closed, and fuel and air are compressed at a compression ratio where spontaneous ignition is generated. In the expansion stroke, an air pump 3 is operated when the piston reaches a top dead center, air from the lower air chamber is injected to the upper air chamber through the bypass 2, and fuel and air are burnt through spontaneous ignition. In an exhaust stroke, burnt mixture is discharged from an exhaust valve 9 in response to the rise of the piston 10. In this case, burning velocity can be controlled at the speed of injection by means of the pump 3, and stable revolution at low speed is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an internal combustion engine whose combustion rate can be controlled.

An example in which this invention is applied to 4 cycle V and V professional engine IcIJii will be explained based on Fig. Wc as follows.

The one shown is a well-known 4-cycle V sidero engine with a partition plate 1, a bypass 2, an air pump 5, an air intake hole 4, and an air intake pulp 5 added, and the conventional intake hole and intake pulp replaced with a fuel intake hole 6. This is an embodiment of the present invention in which the fuel intake pulp 7 is used as the fuel suction pulp 7.

The rotation of this engine is divided into four strokes: intake, compression, expansion, and exhaust, and the operation of each part is explained as follows.

Suction stroke: While the piston 10 moves from the top dead center to the bottom dead center, the fuel suction pulp 7 and the air suction pulp 5 are opened to supply gaseous fuel to the air chamber above the partition plate 1 and the 9 IC chamber below. Let the air breathe. The ratio of fuel and air is such that when mixed, there is complete combustion.

Compression line li: When the previous stroke ends and the piston 10 reaches the bottom dead center, all pulps are closed until it reaches the top dead center again. Set the compression ratio to a value that will cause spontaneous ignition.

Erosion stroke: When the previous stroke ends and the piston 10 reaches the top dead center, all the pulps are kept closed and the air is pumped through the bypass 2 with the air bonder 3 until the piston 10 reaches the bottom dead center. Inject all the air from the chamber into the air chamber containing the fuel. At this time, combustion occurs due to spontaneous ignition.

Exhaust stroke: When the previous stroke ends and the piston 10 reaches the bottom dead center, the exhaust pulp 9 is opened until the piston 10 reaches the top dead center again to exhaust the inside of the aerobium where combustion took place.

As explained above, in this invention, the combustion speed can be controlled by the injection speed of air or fuel injected through the bypass 2, and a more stable low-speed rotation than the conventional engine can be obtained, and there are many types of fuel that can be used.

Claims (1)

[Claims] 1 The combustion chamber is divided into two air chambers with a partition plate that moves easily due to the slight pressure difference between the vacuum chambers and cancels out the difference, and during the intake stroke, air is separated from one air chamber and fuel is separated from the other air chamber. An internal combustion engine that performs combustion by injecting fuel or air from one air chamber to the other through a bypass provided between the vacuum chambers during the expansion stroke.
