An internal combustion engine ICE is a heat engine in which the combustion of a fuel occurs with an oxidizer usually air in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion applies direct force to some component of the engine.

An engine is a device that converts one form of energy into another. A heat engine is a machine in which the chemical energy of a fuel transformed into thermal energy by combustion to produce mechanical work. Heat engines may be classified according to the place where combustion takes place.

External heat engine

The main difference between internal and external combustion engine is that in internal combustion engines, the working fluid burns inside the cylinder, whereas in external combustion engines, combustion takes place outside the cylinder and heat is then transferred to the working fluid. In an internal combustion engine, the working fluid consists of a combustible fluid placed inside a cylinder. Four-stroke Diesel and petrol gasoline engines are internal combustion engines. In these engines, the fluid undergoes combustion inside the cylinder and expands. The expansion pushes a piston which is attached to a crankshaft and produces motion.

Internal-combustion engine

Internal combustion engines provide outstanding drivability and durability, with more than million highway transportation vehicles in the United States relying on them. Along with gasoline or diesel, they can also utilize renewable or alternative fuels e. Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine ICE , the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work. The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft.

An external combustion engine is a heat engine where an internal working fluid is compressed and heated by combustion of an external fuel through the engine wall or a heat exchanger. The fluid then, by expanding and acting on the mechanism of the engine piston or turbine , produces a shaft power. Steam engines and Stirling engines are most known external combustion engines. They may use a supply of heat from any sources such as biomass and biomass derived products, municipal waste, nuclear, solar, geothermal, or exothermic reactions not involving combustion. In the later case they are not then strictly classed as external combustion engines, but as external heat engines. Other important advantages of external combustion engines are low emissions, due to continuous external combustion, and low noise, due to elimination of exhaust of high-pressure combustion products.

An external heat engine EHE refers to any engine that receives its heat from a source other than the fluid that makes the engine work.

What is Internal Combustion Engine

Отказ Хирохито… - Нам нужно число, - повторял Джабба, - а не политические теории. Мы говорим о математике, а не об истории. Соши замолчала. - Полезный груз? - предложил Бринкерхофф.  - Количество жертв. Ущерб в долларах.

  • An external combustion engine EC engine is a heat engine where a working fluid , contained internally, is heated by combustion in an external source, through the engine wall or a heat exchanger. Clodoaldo R. - 07.05.2021 at 11:15
