Rotary internal combustion engine are used in air craft (open cycle gas turbine)
External Combustion Engine:
An engine in which combustion of fuel takes place outside of the cylinder or engine is known as external combustion engine. For example for in steam engine, combustion of fuel takes place outside which convert water into steam and this high pressure steam used to do mechanical work.
These engines are further classified into rotary (Steam Turbine) and reciprocating Engine (Steam Engine).
External combustion engines have wide application in power plant engineering.
Classification of IC engine:
IC engines can be classified on the basis of fuel used, thermodynamic cycle, type of ignition, type of cooling system, cylinder arrangement, method of charging etc. Now we study about it in detail.
According to Cycle of Operation:
We know IC engines convert chemical energy into mechanical energy in a cyclic operation. There are many thermodynamic cycles like Carnot cycle, Otto Cycle, Diesel Cycle, Rankine cycle etc. IC engines works on three cycles Otto cycle and Diesel cycle and Dual cycle. So according to it, IC engine can be classified into following types.
Otto Cycle Engine:
It is also known as spark ignition engine or constant volume heat addition engine, Petrol engine etc. In this cycle heat addition (fuel burn) and rejection (exhaust) takes place at constant volume and expansion and compression takes place at isentropically. These engines give low power at high speed.
Diesel Cycle Engine:
This is known as compression ignition engine, diesel engine, constant pressure engine etc. In this cycle heat addition (fuel burn) takes place at constant pressure and heat rejection takes place at constant volume. This engine gives high power at low speed.
Duel Cycle Engine:
Dual cycle is combination of Otto cycle and Diesel cycle. In this engines, heat addition take place both at constant volume and constant pressure in some ratio.
Some engines works on Strilling cycle and Ericsson cycle but these are not used commercially.
