How does a six stroke engine work?

The working principle of a two-stroke engine is that there are three holes in the engine cylinder block, namely the air intake, exhaust and ventilation holes, which are closed by the piston at a certain time.

First stroke: the piston from top dead center to bottom dead center. Complete two actions.

1. The spark plug is ignited, and the work is done - exhaust.

2. Close the air intake, press the air mixture from the lower part of the piston into the crankcase, and then enter the cylinder from the upper part of the piston.

Second stroke: The piston goes from bottom dead center to top dead center. Complete two actions.

1. Close all intake and exhaust air and compress the mixture.

2. To complete a work cycle, the piston needs to move two strokes, so it is called a two-stroke.

Advantage 1, two-stroke engines do not have valves, which greatly simplifies their structure and reduces their own weight.

2. The two-stroke engine is ignited once every rotation, while the four-stroke engine is ignited once every other rotation. This makes the two-stroke engine an important power base.

3. The two-stroke engine can run in any direction, which is important in some equipment such as chainsaws. A standard four-stroke engine can fail when the oil is shaking, unless it is upright. Solving this problem greatly increases the flexibility of the engine.

These advantages make two-stroke engines lighter, simpler, and cheaper to manufacture. The two-stroke engine also has the potential to pack twice as much power into the same space, as it has twice the power stroke per revolution. The combination of lightness and double power gives it an amazing "thrust-to-weight ratio" compared to many four-stroke engines.

There are three holes in the engine cylinder block, namely the air intake, exhaust and vent, which are closed by the piston at a certain moment. Its duty cycle consists of two strokes: Schematic diagram 1 of a two-stroke engine

The first stroke: the piston moves upwards from the bottom dead center, and after the three air holes are closed at the same time, the mixture entering the cylinder is compressed; When the air intake hole is exposed, the combustible mixture flows into the crankcase. 2.

Second stroke: When the piston is compressed near the top dead center, the spark plug ignites the combustible mixture, and the gas expands to push the piston down to work. At this time, the air intake hole is closed, and the combustible mixture sealed in the crankcase is compressed; When the piston approaches the bottom dead center, the exhaust hole is opened, and the exhaust gas is flushed out; Then the vent is opened, and the pre-pressurized combustible mixture punches the cylinder to expel the exhaust gas and carry out the ventilation process.

The average four-stroke engine dissipates the energy of 3 4 in the form of heat. Six-stroke engines use some of the heat energy emitted to produce steam, which is part of the energy that would otherwise be lost.

After the four strokes of an ordinary four-stroke engine, the water is sprayed into the red-hot cylinder, and the water immediately becomes steam with a temperature of up to 816 degrees, and the volume expands sharply by 1,600 times.

At the same time, the pressure in the cylinder increases dramatically, pushing the piston to work again – so that 2 out of every 6 strokes occur without the same amount of fuel consumed. By the 6th stroke, the engine discharges the water vapor to a cooler, where the water vapor turns back into water.

How a two-stroke engine works:

The working principle of the two-stroke engine is that the piston moves upwards from the state and the wild lease, and after the three holes are closed at the same time, the mixture entering the cylinder is compressed; When the air intake hole is exposed, the combustible mixture flows into the crankcase. When the piston is compressed near the top dead center, the spark plug ignites the combustible mixture, and the gas expands to push the piston downward. At this time, the air intake hole is closed, and the combustible mixture sealed in the crankcase is compressed; When the piston approaches the bottom dead center, the exhaust hole is opened, and the exhaust gas is flushed out; Then the vent is opened, and the pre-pressurized combustible mixture is rushed into the cylinder to expel the exhaust gases and carry out the ventilation process.

Two-stroke engines produce a lot of pollution, and pollution comes from two sources. The first is the combustion of lubricating oil. In a way, the lubricant fills all two-stroke engines with smoke, and a very worn two-stroke engine can release large clouds of oily fumes.

The second reason is not obvious. Whenever a large amount of fresh air fuel is injected into the combustion chamber, some of it leaks out of the exhaust port. That's exactly why you'll see a glossy lube around any two-stroke jet ski.

The release of hydrocarbons from new fuel mixed with leaking lubricant is a major problem for the annular ridge flare.

There are three holes in the cylinder block of the two-stroke engine, namely the air vent, the exhaust hole and the air intake hole, and these three holes will be closed by the piston for a certain period of time when working brother. So how does a two-stroke engine work?

The two-stroke principle consists of two stroke duty cycles

First stroke: It mainly refers to the piston when it slowly moves up from the bottom dead center, then the three holes will be closed at the same time, and the mixture will be compressed when it enters the cylinder. When the air intake hole is exposed, a combustible mixture flows into the crankcase.

Second stroke: When the piston is about to be compressed to the top dead center, the spark plug will ignite the mixture, and when the gas is in the process of expansion, it will slowly push the piston downward, and the air intake will be closed. On the contrary, when the piston is close to the bottom dead center, the exhaust hole will be opened to exhaust all the exhaust gas inside, and then the vent will be opened, and when the combustible mixture is pre-pressurized, it will flow into the cylinder, and the exhaust gas will be discharged.
