          FOUR STROKE, DIESEL CYCLE, COMPRESSION IGNITION ENGINE The engine of heavy motor vehicle ( like truck, buses) stationary power plant big industrial units and ships mostly operate on diesel cycle or constant pressure cycle. It was introduced by Dr Rudolph Diesel in 1897. Diesel cycle differs from Otto cycle in one respect. The heat is added at constant pressure instead of at constant volume. Thus, it comprises two adiabatic process, one constant pressure heat addition process and one constant volume heat rejection process. Diesel cycle engines mostly use heavy oils. Diesel oil is the most common. Diesel cycle engine only air is compressed in the cylinder to a high pressure, the temperature of nice compressed air Sufficiently high to ignite fuel. Diesel is injected in the cylinder at the end of compression stroke which itself ignitor new to high temperature of the compressed air. There is no spark plug in diesel engine. In a four stroke diesel cycle, co...
