Difference between internal combustion engine and external combustion engine pdf
File Name: difference between internal combustion engine and external combustion engine .zip
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.
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.

Internal-combustion engine , any of a group of devices in which the reactants of combustion oxidizer and fuel and the products of combustion serve as the working fluids of the engine. Such an engine gains its energy from heat released during the combustion of the nonreacted working fluids, the oxidizer-fuel mixture. This process occurs within the engine and is part of the thermodynamic cycle of the device. Useful work generated by an internal-combustion IC engine results from the hot gaseous products of combustion acting on moving surfaces of the engine, such as the face of a piston , a turbine blade, or a nozzle. Internal-combustion engines are the most broadly applied and widely used power-generating devices currently in existence.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office files or records, but otherwise reserves all copyright rights whatsoever. The present invention relates to an external combustion engine, and more particularly, to a hydrogen fueled external combustion engine and a method to convert an internal combustion engine thereto, with application of this invention being for engines used in transportation, whether on land, water, or in the air. A secondary use may be in stationary engines. Global carbon based fuel consumption in vehicles to move people, as well as deliver goods and services, has created significant air and water quality problems throughout the world, and in particular in industrialized countries.
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. The fluid then, by expanding and acting on the mechanism of the engine, produces motion and usable work. In these types of engines, the combustion is primarily used as a heat source, and the engine can work equally well with other types of heat sources. Engines of similar or even identical configuration and operation may use a supply of heat from other sources such as nuclear, solar, geothermal or exothermic reactions not involving combustion; they are not then strictly classed as external combustion engines, but as external thermal engines. Gas is used in a Stirling engine.
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. The most common type of EHE is the external combustion engine, which is used in many power plant designs. External heat engines are generally steam engines, and they differ from internal combustion engines in that the heat source is separate from the fluid that does work. This is different from internal combustion, like in a car engine, where the gasoline ignites inside a piston , does work, and then is expelled. All external combustion engines are external heat engines.
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. Furthermore, learn about why does knocking occurs in an engine. Moreover, also check out various types of steam engines used in industries. If the combustion of fuel takes place inside the working cylinder, the engine is known as an internal combustion engine I. C engine.
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.
