How Does a 2 Cylinder Diesel Engine Work?
A 2 cylinder diesel engine works based on the principle of compression ignition. The process involves four main strokes: intake, compression, power, and exhaust.
- Intake Stroke:
- Air enters the cylinder through an open intake valve.
- The piston moves downward, creating space for air to fill the cylinder.
- Compression Stroke:
- The piston moves upward, compressing the air inside the cylinder.
- The compressed air becomes hot due to increased pressure.
- Power Stroke:
- Diesel fuel is injected into the heated air in the cylinder.
- The fuel ignites spontaneously because of the high temperature.
- The explosion pushes the piston down, generating power and motion.
- Exhaust Stroke:
- The exhaust valve opens as the piston moves upward again.
- Burned gases are expelled from the cylinder through the exhaust valve.
Each cylinder of the engine follows this cycle in a balanced sequence. The alternation ensures constant power output. The process is efficient and generates ample torque for tasks like operating small machines or vehicles.
A two-cylinder design simplifies the operation and reduces weight. Despite its simplicity, it provides enough performance for light-duty applications. This makes the 2 cylinder diesel engine a preferred option for many industries.
