Various Ways By Which Internal Combustion Engines Can Be Classified

An Internal Combustion Engine is a type of combustion engine that converts chemical energy into thermal energy,to produce useful mechanical work.In an Internal combustion engine,combustion chamber is an integral part of the working fluid circuit.

Working Principle of an Internal Combustion

Internal combustion engines can be classified into a large number of types based on several criteria. The classification of IC engines is given below:

According to fuel used:
+Diesel engine
These engines use diesel as the fuel.They are used in trucks, buses,cars etc.

+Petrol engine
These engines use petrol as the fuel.They are used in bikes,sport cars,luxury cars etc.

+Gas engine
These engines use CNG and LPG as the fuel. These are used in some light motor vehicles

Based on the type of cycle
+Otto Cycle Engine
+Diesel Cycle Engine
+Dual Cycle Engine

Based on the number of strokes per cycle
+Two-stroke Engine e.g motorcycles and lawnmowers
+Four-stroke Engine e.g cars,trucks

Based on the number of cylinders
+Single Cylinder Engine e.g motorcycles and motor scooters
+Multi cylinder Engine
+Twin Cylinder Engine
+Three Cylinder Engine
+Four Cylinder Engine
+Six Cylinder Engine
+Eight Cylinder Engine
+Twelve Cylinder Engine
+Sixteen Cylinder Engine

Based on the type of ignition
+Compression ignition engine
Burning of fuel starts due to temperature rise during compression of air(no spark plug).

+Spark ignition engine
Ignition of fuel is started by a spark,generated inside the cylinder by sparkplug.

Based on the lubrication system used
+Dry sump lubricated engine e.g racing cars and aerobatic aircraft
+Wet sump lubricated engine

Based on the cooling system used
+Air-cooled Engine
+Water-cooled Engine

Based on the arrangement of valves
+L-head Engine
+I-head Engine
+T-head Engine
+F-head Engine

Based on the position of cylinders
+Radial Engine

+V Engine

+W Engine

+Horizontal Engine
+Vertical Engine
+Inline Engine
+Opposed Piston Engine
+Opposed Cylinder Engine

Based on the pressure boost given to the inlet air or air-fuel mixture
+Naturally aspired Engine
+Supercharged Engine
+Turbocharged Engine
+Crankcase compressed Engine

Based on application
+Automobile Engine
+Aircraft Engine
+Locomotive Engine
+Marine Engine
+Stationary Engine
