1. Engines

2. TYPE OF ENGINES Depends on fuel Depends on location Depends on working principles

3. TWO STROKE PETROL ENGINE Piston moves down transferring fuel-air mix to cylinder and ejecting exhaust Piston moves up - compression and ignition. Suction of new mix in the sump [Goring, L.1990, Marine inboard engines: petrol and diesel, London: Adlard Coles]

4. LOOP SCAVENGING [Goring, L.1990, Marine inboard engines: petrol and diesel, London: Adlard Coles] How two stroke engine work

5. FOUR STROKE CYCLE [Goring, L.1990, Marine inboard engines: petrol and diesel, London: Adlard Coles] Two stroke vs. four stroke

6. Volume-Pressure diagram [Calder, N, 1996, Marine Diesel Engines, Shrewsbury: Waterline]

7. TWO STROKE DIESEL First stroke [Goring, L.1990, Marine inboard engines: petrol and diesel, London: Adlard Coles]

8. TWO STROKE DIESEL Second stroke [Goring, L.1990, Marine inboard engines: petrol and diesel, London: Adlard Coles]
