What is the working principle of 2-stroke engine?
What is the working principle of 2-stroke engine?
Overall, a two-stroke engine contains two processes: Compression stroke: The inlet port opens, the air-fuel mixture enters the chamber and the piston moves upwards compressing this mixture. A spark plug ignites the compressed fuel and begins the power stroke.
What are the applications for 2-stroke engine?
For these reasons, two-stroke engines are ideal in applications such as chainsaws, weed eaters, outboard motors, off-road motorcycles and racing applications. Due in part to their design and lack of an oil sump, two-stroke engines are also easier to start in cold temperatures, making them ideal for use in snowmobiles.
Which type of lubrication system is used in 2-stroke engine?
mist lubrication
In two-stroke engines, mist lubrication is used where crankcase lubrication is not suitable. In a two-stroke engine, as the charge is compressed in the crankcase, it is not possible to have the lubricating oil in the sump. Hence, mist lubrication is adopted in practice.
Which fuel is used in 2-stroke engine?
Fuel for a 2-stroke engine has a small amount of oil mixed into it. It is called a “2-stroke” because just one up and down movement of the piston—the 2 strokes—performs the full cycle of intake, compression, combustion and exhaust.
How many ports does a 2-stroke engine have?
three ports
Detailed Solution. A two-stroke engine has three ports: Suction Port: It is the port through which the engine gets the fuel. It is generally connected to the carburetor in the case of an SI engine.
Which type of lubrication system is used in 2 stroke engine?
How many cylinders does a 2 stroke engine have?
The three-cylinder, opposed-piston, two-stroke engine configuration has slightly overlapping gas-exchange events, resulting in a phenomenon known as cross charging. In a two-cylinder configuration, however, the gas-exchange events are too timely separated.
