Cycles of a 2 stroke Diesel Engine

What are the cycles of a 2 stroke Diesel Engine? Chronologically.
1. Compression. 2. Injection. 3. Power. 4. Exhaust. 5. Scavenge. 6. Post-Scavenge
1 of 8
Describe 1st cycle of a 2 stroke Diesel Engine, including angle
1-2 COMPRESSION. 110° BTDC. The EXHAUST VALVE is closed and the piston is moving up the cylinder.
2 of 8
Describe 2nd cycle of a 2 stroke Diesel Engine, including angle
2-3 INJECTION. 8° BTDC. Just before TDC fuel is injected into the cylinder. This injection carries on until just after TDC.
3 of 8
Describe 3rd cycle of a 2 stroke Diesel Engine, including angle
3-4 POWER. 10° ATDC. The expanding gas from burning fuel pushes the piston downwards in the cylinder, turning the crankshaft and producing work.
4 of 8
Describe 4th cycle of a 2 stroke Diesel Engine, including angle
4-5 EXHAUST BLOWDOWN. 110° ATDC. The exhaust valve opens and the exhaust gas starts to leave the cylinder.
5 of 8
Describe 5th cycle of a 2 stroke Diesel Engine, including angle
5-6 SCAVENGING. 140° ATDC. The Piston uncovers the scavenge ports. Air at a pressure greater than atmospheric enters the cylinder and pushes out the remaining exhaust gas.
6 of 8
Describe 6th cycle of a 2 stroke Diesel Engine, including angle
6-1 POST - SCAVENGE. 140° BTDC. As the piston moves up the cylinder, the scavenge ports are covered. The exhaust valve then closes and compression begins.
