WHAT IS SIX STROKE ENGINE???
The SIX-STROKE Engine is a type of internal combustion
engine based on the four-stroke engine, but with additional
complexity intended to make it more efficient and reduce
There are two power strokes: one with fuel, the other with
steam or air.
CROWER SIX STROKE ENGINE
The CROWER six-stroke engine is a claimed high-efficiency
variant of an internal combustion engine under development
by Bruce Crower.
Two extra strokes are added to the customary internal
combustion engine, which makes a six stroke engine. A third
down-stroke is a "steam stroke" and a third up-stroke exhausts
the expanded steam while venting heat from the engine.
In a six-stroke engine, when the combustion chamber
temperature reaches approx. 400 °F (200 °C). Just before the
fifth stroke, fresh water is injected directly into the
hot combustion chamber through the engine's fuel injector
pump, which is quickly turned to superheated steam, which
causes the water to expand to 1600 times its volume and
forces the piston down for an additional Power stroke.
There is 40% reduction in fuel consumption.
Extracts work from heat that is ordinarily lost through the
cooling system of a conventional engine.
Reduces exhaust emissions per a given power range.
Steam stroke cools the engine internally hence the use of much
higher compression ratios.
The weight and power loss of conventional cooling system
parts can be eliminated.
LIMITATIONS AND OBSTACLES
Injecting relatively cold water onto a hot metal piston can
damage it over time from thermal expansion and contraction.
Separate water tank would have significant weight and space
A steam-free cool down reduces the temperature inside the
Cold climate anti-freezing measures would be needed in the
To prevent damages due to the action of cold water, we can
utilize the exhaust gases for pre- heating of water.
We can use a condenser instead of a separate water tank
which will reuse the distilled water for a period of cycles.
To compensate the temperature drop inside the chamber we
can further increase the Compression ratio which increases
the power output making it suitable for higher power
The concept of Six Stroke Engine seems to be rather eco-
friendly and low fuel consuming which can fulfill the needs of
A lot of experiments are being conducted in order to improve
the efficiency and workability of the engine.
