Abstract

The present invention provides a two-stroke engine. According to the invention, the operations of air-intake and air-exhausting are combined at the end of power stroke and at the front end of compression to be conducted simultaneously. The two-stroke of compression and power includes a process of explosion which has the advantages of a four-stroke engine. A piston in the cylinder head is used to divide the waste gas from the combustible mixture gas. The air-intake operation and the exhaust discharge operation are carried out simultaneously. A bottom dead center (BDC) below a reciprocating piston engine is formed with an air discharge aperture and installed with an exhaust pipe for discharging air. The cylinder head is installed with an intake manifold and a check valve. The hydraulic pressure pushes the piston for performing the air discharge and air-intake operations. A spark plug ignites the compressed fuel gas mixture, and the explosion pushes the piston to move up-and-down. Subsequently, the connecting rod crankshaft rotates for 120 degrees. The hydraulic pressure from the cylinder head pushes the piston to perform an air discharge operation. At this time, the crankshaft rotates for 120 degrees and passes through the connecting rod to push the piston for performing the up-and-down movements in order to compress the mixture gas. The compressed air passes through the piston sleeve and enters the combustion chamber, thereby completing each working cycle of two up-and-down strokes of the piston. That is, the crankshaft rotates one cycle of 360 degrees.

Description

Intake and exhaust disc piston three-cylinder two-stroke gasoline engine

The two-stroke engine is subject to exhaust The influence of flow resistance and combustion chamber volume, so the residual exhaust gas remaining in the cylinder at the end of the exhaust gas is hindered to the intake stroke of the next cycle, so the exhaust gas is required to be as clean as possible, at the top dead center of the engine The cylinder head device discharges the intake piston, and the cylinder wall has a vent hole and an exhaust pipe at the bottom dead center. The hydraulic system pushes the exhaust piston to the bottom dead center to exhaust the residual exhaust gas, and the cylinder head has a check valve and an intake valve. The hole, combined with the fuel mixture entering the cylinder, is beneficial to the fuel mixture in the cylinder, the compressed fuel mixture and the spark plug ignite the fuel mixture, the explosion pushes the piston, and the residual exhaust gas remaining in the cylinder is clean, the combustion efficiency is the same as the four strokes. The engine is the same and the horsepower and torque are large. The vent hole only occupies one-fifth of the piston stroke. The piston's explosive force in the cylinder does not affect the power output loss. The mixed fuel gas does not need to enter the cylinder through the crankcase, but directly enters the cylinder. The engine is circulated and lubricated, and the oil pump presses the oil to the place where lubrication is required.

Two-stroke engine output power is the same size The four-stroke engine is large. Because the four-stroke engine has one power output per four strokes, and the two-stroke engine has two times, the four-stroke gasoline engine passes through four processes of intake, compression, combustion, and exhaust to complete a working cycle, during which the piston is on, Four strokes are reciprocated between the bottom dead center, and the crankshaft rotates two times accordingly. The single cylinder four-stroke engine has only one stroke force per working cycle (two rotations of the crankshaft), which inevitably results in poor uniformity of rotation between the internal combustion engine and the working machine. Improve the smoothness of operation and improve the balance. The automobile engine generally adopts a combination of multiple single-cylinder machines. In the two-stroke gasoline engine cylinder of the present invention, only half of the four-stroke gasoline engine can improve the running stability, and the four-stroke gasoline engine has a cylinder.

At the end, there is no force to rotate the crankshaft, and the exhaust gas pushes down four-fifths of the piston stroke through the disc piston, and reciprocates with the cylinder piston to guide the exhaust gas. According to the scope of the patent application, the intake and exhaust disc piston three-cylinder two-stroke gasoline engine device, wherein the crank arm is at a position corresponding to three cylinders, the crank arms are at an angle of 120 degrees, the crankshaft and each corresponding cylinder The first cylinder is the power explosion power stroke, the second cylinder is the intake and exhaust stroke, and the third cylinder is the compression stroke. According to the third cylinder of the second application, the three cylinders are connected in parallel, and each cylinder completes the two-stroke cycle operation, in which the explosion stroke, the cylinder piston passes through the compression stroke terminal, and the spark plug ignites the casing tube. The fuel mixture, the flame passes through the casing tube, the vent hole of the casing tube, to the combustion chamber between the disc piston and the cylinder piston, ignites the fuel mixture of the combustion chamber, and the explosion expansion gas separates the cylinder piston and the disc piston. The cylinder piston pushes the crank arm and the crank arm pushes the crankshaft to rotate. According to the second cylinder of the second application, the three cylinders are connected in parallel, and each cylinder completes the two-stroke cycle operation, in which the intake and exhaust strokes, after the combustion explosion, push the cylinder piston down, the cylinder wall is filled with exhaust gas, and the other One cylinder is starting at the compression stroke, the hydraulic cylinder and the connecting rod device are forced by the cylinder piston, the hydraulic oil is injected into the other cylinder hydraulic cylinder through the hydraulic pipeline, the connecting rod pushes the disc piston downward, and the exhaust gas in the cylinder wall is discharged through the exhaust hole When the disc piston is pushed down, the cylinder body space above the disc piston generates a negative pressure to push the intake port back valve device, and the fuel mixture is sucked into the cylinder. According to the second aspect of the patent application scope, three cylinders are connected in parallel, and each cylinder completes a two-stroke cycle operation, in which the compression stroke and the three crank arms are each at a 120-degree angle, one of which starts when the explosion power stroke starts. The crankshaft is connected to push the crankshaft arm of the other cylinder to start the compression stroke. The cylinder piston contacts the disc piston and pushes to the top dead center of the cylinder head. The fuel mixture is compressed by the disc piston and enters the combustion chamber between the disc piston and the cylinder piston through the casing tube.
