The four strokes of the four-stroke engine are intake stroke, compression stroke, combustion stroke and exhaust stroke respectively. Among them, only the combustion stroke is external work, and the other three-strokes rely on the inertia of the crankshaft (flywheel) to maintain operation.
The engine's completion of air intake, compression, work and exhaust is called a working cycle. It takes four strokes to complete this working cycle, and the crankshaft rotates twice, so it is called a four-stroke engine.In order to complete this work cycle, it is necessary to have a gas distribution mechanism to realize the regular opening and closing of the valve.
Two reciprocations, the first movement from the upper stop point to the lower stop point is inhalation. The second movement from the lower stop point to the upper stop point is compression, the third movement from the upper stop point to the downward movement is the workmanship stroke, and the last movement from the lower stop point upwards is the exhaust stroke, a total of four strokes, and the piston moves up and down in the cylinder twice.
The four strokes are intake stroke, compression stroke, work stroke and exhaust stroke. Except for the work stroke, the other three are powerless output strokes, that is, ineffective strokes. The operation of the engine depends on the inertia of the flywheel and the working stroke of the engine.
Exhaust stroke: the piston moves from the bottom up, and the flywheel rotates for half a week (relying on inertia).
1. Intupstroke 2. Compression stroke 3. Do the work stroke 4. Exhaust stroke. In the intake stroke In this stroke, the intake valve opens, the exhaust valve is closed, the cylinder is connected to the carburetor, the piston moves from the upper stop point to the working point, and the volume above the piston increases, resulting in the necessary vacuum degree in the cylinder.The combustible mixture is sucked into the cylinder.
2. Four strokes include (inhalation stroke, compression stroke, work stroke, exhaust stroke). The cycle begins at the upper stop point, that is, the piston is at its top position. Introduction When the piston is in its first downward movement (air intake stroke), the mixture of fuel and air is injected into the cylinder through one or more valves.
3. The four strokes of a four-stroke engine are intake stroke, compression stroke, workstroke and exhaust stroke. Intake stroke: the stroke of the piston falling to inhale the mixed gas (fuel-containing air) into the cylinder. Compression stroke: the stroke of the piston rising to the upper stop point and compressing the mixture.
In a four-stroke piston engine, the stroke of the work is ().
Inhalation, compression, explosion, exhaust. The explosion is working. Power the machine.
The stroke of converting internal energy into mechanical energy during the working process of a four-stroke diesel engine is the working stroke.
Work stroke In this journey, the intake and exhaust valves are still closed all the time. When the piston approaches the upper stop point, the spark plug installed on the cylinder block or cylinder head emits an electric spark to ignite the compressed combustible mixture. When the combustible mixture burns, a large amount of heat energy will be released, and its pressure and temperature will be rapid. Increase.
The four strokes of a four-stroke engine are intake stroke, compression stroke, workstroke and exhaust stroke.
1. It is called a stroke. Most ordinary internal combustion engines are four-stroke internal combustion engines. It is divided into intake stroke, compression stroke, work stroke and exhaust stroke. There are mainly four-stroke gasoline engines and four-stroke diesel engines. The fuel used by the earliest four-stroke internal combustion engine was gas.
2. The four strokes of the four-stroke engine are intake stroke, compression stroke, workstroke and exhaust stroke. The stroke is interpreted as the journey, the process from one position to another. The stroke of the automobile engine refers to the process of the piston from the upper stop point to the lower stop point in the cylinder, and also refers to the process of the piston from the lower stop point to the upper stop point.
3. The stroke generated by the power of the four-stroke engine is the working stroke, which is the third stroke of the work of the stroke engine.The four strokes of the four-stroke engine are intake stroke, compression stroke, workstroke and exhaust stroke.
