About Four-stroke engine
Four Stroke Cycle Engines. A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.
Intake stroke:The piston moves downward to the bottom, this increases the volume to allow a fuel-air mixture to enter the chamber.
Compression stroke:The intake valve is closed, and the piston moves up the chamber to the top. This compresses the fuel-air mixture. At the end of this stroke, a spark plug provides the compressed fuel with the activation energy required to begin combustion.
Power Stroke:As the fuel reaches the end of it’s combustion, the heat released from combusting hydrocarbons increases the pressure which causes the gas to push down on the piston and create the power output.
Exhaust stroke:As the piston reaches the bottom, the exhaust valve opens. The remaining exhaust gas is pushed out by the piston as it moves back upwards.
What are four stroke engines used for
The four-stroke engine is the most common types of internal combustion engines and is used in various automobiles (that specifically use gasoline as fuel) like cars, trucks, and some motorbikes
Why is 4 stroke engine better
Two-stroke engines don’t live as long as four-stroke engines. The lack of a dedicated lubrication system means that the parts of a two-stroke engine wear-out faster. Two-stroke engines require a mix of oil in with the gas to lubricate the crankshaft, connecting rod and cylinder walls.
.The product comes with a water cooling channel, but the external water-cooled pipe and the external water pump need to be purchased separately. You can also purchase the water-cooling kit of this shop. With the use of it, the conversion potential is large, and you don’t need to reprocess the water cooling channel yourself.
.Small and powerful,It weighs 395.5g, CDI and spark plug kits are not included in the startup and need to be purchased separately. CDI and spark plug sleeves are common conditions, and CDI and spark plug kits of other similar products can also be used for this product.
.If you use gasoline above No.92, the gasoline needs to be proportioned to the oil. The oil is 2T (2-stroke engine oil, the type used for ordinary motorcycles), which is adjusted from 1:25 to 1:30. A litre of petrol needs 40ml of oil
.Working Principle:Using methanol as fuel. The process of moving from one end of the cylinder to the other when the piston reciprocates within the cylinder is called a stroke
.The four-stroke engine is divided into an intake stroke, a compression stroke, a power stroke and an exhaust stroke
