the internal combustion engine works by converting chemical energy (fuel) into heat energy. the heat energy then expands the compressed air to drive the piston down. typically a third of this heat goes straight out of the exhaust, which is why the exhaust gets hot. another third of the heat is absorbed into the engine, hence the need for a cooling system which means that only a third of the heat generated is used to drive the psiton down making the internal combustion engine only about 33% efficient. robb
a gasoline engine is an Internal combustion engine
Internal combustion engine.
and internal combustion engine and a gasoline engine are the same thing.
Reciprocating engines (piston engines) are internal combustion engines. Rotary engines ( Wankel engine) is also an internal combustion engine. In general, all types of engines in which the combustion chamber is an integrating part of the engine is considered a internal combustion engine.
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
Internal combustion engines are now operating at about 30-40 % efficiency with the application of computer controls and continues to get better all the time. I am not sure of the efficiency rating of external combustion or central combustion engines. I will make an attemp to find out. Note that these engines to my knowledge are only used by the military in torpedoes so I am not sure if there is any info available to the general public. I have seen electric motors up to 55% efficiency. I am not sure if there are more efficient motors out there but I would bet yes.
combustion engine
The four-stroke engine used in automobiles is an example of an internal combustion engine.
In an internal combustion engine fuel is burned in a combustion chamber or cylinder inside the engine
The waste products of combustion leave the internal combustion engine through the exhaust valve.
The automotive industry was the net result of the internal combustion engine, because the engine addressed the deficiencies of external combustion engines for road vehicles. The steam engine was the precursor to gas-fired piston engines (1860s), and the invention of the diesel internal combustion engine by Rudolf Diesel, a German scientist, in 1897. An early gasoline engine was built by Wilhelm Maybach in 1890. To this day, the basic form of the engine remains the same, although with many innovations to improve performance and efficiency.
The internal combustion engine give rise to the auto industry.
