  1. Diesel Engine • The only difference between diesel engine and a four-stroke • gasoline engine is: • No sparkplug on Diesel engine. • Has a higher compression ratio. • (14:1 to 25:1) • Better fuel mileage.

  2. Diesel Engine Intake Stroke: • Piston moves from TDC to BDC • creating vacuum in the cylinder • Intake valve opens allowing only • air to enter the cylinder and • exhaust valve remains closed

  3. Diesel Engine Compression Stroke • Both valves stay closed • Piston moves from BDC to TDC, • compressing air to 22:1 • Compressing the air to this extent • increases the temperature inside the • cylinder to above 1000 degree F.

  4. Diesel Engine Power Stroke • Both valves stay closed • When the piston is at the end of • compression stroke(TDC) the injector • sprays a mist of diesel fuel into the • cylinder. • When hot air mixes with diesel fuel • an explosion takes place in the cylinder. • Expanding gases push the piston • from TDC to BDC

  5. Diesel Engine Exhaust Stroke • Piston moves from BDC to • TDC • Exhaust valve opens and the • exhaust gases escape • Intake valve remains closed

  6. Diesel Engine Four Strokes of Diesel Engine
