Engine Types


Four-Stroke Engine :-

four-stroke engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle. An operating cycle requires two revolutions (720°) of the crankshaft.

Diesel Engine :- 

An internal combustion engine that uses the heat of highly compressed air to ignite a spray of fuel introduced after the start of the compression stroke.one cycle of a four-stroke diesel engine :-

A. intake stroke
B. compression stroke
C. power stroke
D. exhaust stroke

Two-Stroke Engine :-

A two-stroke engine is a type of internal combustion engine which completes a power cycle with two strokes of the piston during only one crankshaft revolution.

In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust functions occurring at the same time.

Wankel Engine :-

rotary internal combustion engine in which a triangular rotor turning in a specially
shaped housing performs the functions allotted to the pistons of a conventional engine, thereby allowing great savings in weight and moving parts.
A type of four stroke internal combustion engine without reciprocating parts. It consists 
of one or more approximately elliptical combustion chambers within which a curved 
triangular shaped piston rotates, by the explosion of compressed gas, dividing the 
combustion chamber into three gas tight sections

Atkinson Engine :-

Is a type of internal combustion engine. The Atkinson cycle is designed to provide efficiency at the expense of power density. A modern variation of this approach is used in some current hybrid electric applications.

Gnome Rotary Engine :-

The gnome rotary engine was a type of internal-combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary in operation, with the entire crankcase and its attached cylinders rotating around it as a unit.
the most common types of cylinder layout you’ll find in engines today
  • Singles are typically used in motorbikes, snowblowers, chainsaws etc.
  • V-twins are also found in motorbikes.
  • The triple is almost unique to Triumph motorbikes where they call it the Speed Triple.
  • Inline-fours are the mainstay of car engines, as well as being found in some motorbikes too such as the BMW K1200S.
  • Inline fives used to be used a lot in Audis but have found a new home in current Volvos.
  • The V5 is something you’ll find in some VWs.
  • The V6 has the benefits of being smoother than an inline-four but without the fuel economy issues of a V8.
  • Boxer engines are found in BMW motorbikes
