2. 5.1.2011 Compression-ignition engine is a type of an internal combustion engine Because it converts heat into work, it belongs among heat engines. Unlike spark-ignition engines, the fuel mixture is ignited by the heat resulting form the compression of the mixture. The fuel is injected into the combustion chamber in the final stage of the compression.

4. Operation Compression-ignition engines are often also called Diesel engines, after the European inventor and mechanical engineer Rudolf Christian Karl Diesel It operates using the so called Diesel cycle.

5. 5.1.2011 The picture shows a p-v diagram for the diesel cycle, which follows four distinct processes. 1 to 2: compression (blue) 2 to 3: constant pressure heating (red) 3 to 4: expansion (yellow) 4 to 1: constant volume cooling (green)

6. 5.1.2011 Types  There are two sorts of compression-ignition engines, divided by the type of the combustion cycle:  four-stroke cycle: the most common diesel engines, used for many motor vehicles, especially buses, trucks and often also for cars  two-stroke cycle: used especially for large engines for locomotives or boats. They have better power-to-weight ratio, and lower fuel consumption.
