What are Different types of Automobile Engine - Engine & Its Classification

 Engine

An Engine is a machine that converts heat energy into mechanical Energy. The heat from burning a fuel produces power that moves the vehicle. Sometimes the engine is called the power plant. Automotive engines are internal combustion engines because the fuel that runs them is burned internally or inside the cylinder of the engines.

Engine Types and Classification: 

Engines are classified into two types, which are 

i) Internal Combustion Engines. 

ii) External Combustion Engine. 

i) Internal Combustion Engine: 

In an external combustion engine, the combustion of fuel takes place outside the engine. And mostly the fuel used is coal wood etc.

ii) External Combustion Engine: 

In an internal combustion engine, the combustion of fuel takes place inside the engine. Such as Two-stroke and four-stroke diesel and petrol engines.

Automotive Engines can be classified according to : 

i) Number of Cylinders. 
ii) Arrangement of cylinders.
iii) Arrangement of valves and valve trains.
iv) Type of cooling.
v) Number of storekeeper cycles (two of four).
vi) Type of fuel burned. (Petrol, Diesel & Gas Engine).
vii) Method of Ignition (SI & CI Engine).
viii) Firing order.    
ix) Reciprocation or rotary.
