Understanding the Basics of Two Cylinder Diesel Engines
Two cylinder diesel engines operate on the principle of internal combustion, employing a compression ignition mechanism. This design features two cylinders, which are crucial for converting fuel into mechanical energy. The engine’s efficiency is achieved through a series of strokes: intake, compression, combustion, and exhaust.
Internal Components
The main components of a two cylinder diesel engine include:
- Cylinders: Houses the pistons and facilitates the combustion process.
- Pistons: Moves up and down within the cylinders, converting pressure into mechanical energy.
- Crankshaft: Converts linear motion from the pistons into rotational motion.
- Fuel Injector: Sprays fuel into the combustion chamber for ignition.
Working Principle
The operation begins with the intake stroke, where air enters the cylinder. During the compression stroke, the piston compresses the air, increasing its temperature. Fuel is injected into the high-temperature air, causing ignition and resulting in a power stroke. Finally, the exhaust stroke expels combustion gases.
