An engine or motor is a machine designed toconvert energy into useful mechanical motion. Heatengines, including internal combustion engines andexternal combustion engines (such as steam

engines) burn a fuel to create heat which is thenused to create motion. Electric motors convertelectrical energy into mechanical motion, pneumaticmotors use compressed air and others, such as wind-up toys use elastic energy. In biological systems,molecular motors like myosins in muscles usechemical energy to create motion.

The six-stroke engine is a type of internal

combustion engine based on the four-stroke

engine, but with additional complexity to make it

more efficient and reduce emissions.

First concept of this engine are represent by

MalcolmBeare.

The pistons in a six stroke engine goes up and down

total six times for each injection of fuel.

Designs either use steam or air as the working fluid forthe additional power stroke.

six-stroke engine with external and internal combustion

and double flow is similar to the actual internal

reciprocating combustion engine

i. Reduction in fuel

consumption by at least

40%.

ii. Thermal efficiency

reaching 50% .

iii. Two expansions (work) insix strokes.

IV. Dramatic reduction in pollution up to 60% to 90%

depend upon types of fuel and also reduce a noise

pollution.

V. Cooling system is not required so reduce engine

weight.

VI. The engine can run on a variety of fuels, ranging

from diesel to LPG or animal grease.

VII. Cost comparable to those of a four-stroke engine.

Motorboats might offer a big outlet for this type ofengine Furthermore, the use of fuels other thangasoline would greatly reduce the risks of explosion.

Motor-pumps, generator sets, stationary engines,etc....intended for agriculture and industry.

Many more applications may also be envisaged.

Drastically reducing fuel consumption andpollution without radically affecting performances

would allow the current concept of the automobile

to be reassessed.

There is, at this day, no wonder solution for the

replacement of the internal combustion engine.

Only improvements of the current technology can

help it progress within reasonable time andfinancial limits. The six-stroke engine fits perfectly

into this view.
