Most furnaces are not a combustion engine of any kind, though they do consume fuel. In most furnaces that use a fuel supply (as opposed to purely…
What is an example of an external combustion engine?
For example, an external combustion engine would use a flame to heat water into steam, then using the steam to turn a turbine. … A boiling water reactor, which is an external heat engine. All external combustion engines are external heat engines.
What is an example of an internal combustion engine?
Internal-combustion engines are the most broadly applied and widely used power-generating devices currently in existence. Examples include gasoline engines, diesel engines, gas-turbine engines, and rocket-propulsion systems.
How many types of external combustion engines are there?
Engines are classified into two types, viz., IC engine, and external combustion (EC) engine. In IC engines, the combustion of fuel takes place inside, whereas in EC engines the fuel combustion takes place outside the cylinder.
What is internal and external engine?
The internal combustion of fuel takes place inside the working cylinder. Whereas the external combustion of fuel takes place outside the working cylinder. The working fluid used in the internal combustion engine is maybe Petrol, Diesel & Various types of gases. … The internal combustion engine requires less space.
What is the difference between internal and external combustion?
External engines have a working fluid that is heated by the fuel. Internal combustion engines rely on the explosive power of the fuel within the engine to produce work. … In external combustion engines, combustion heats a fluid which, in turn, does all the work.
What are the main parts of external 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.
What are the four steps of an internal combustion engine?
The cycle includes four distinct processes: intake, compression, combustion and power stroke, and exhaust.
What are internal combustion engines used for?
Internal combustion engines (ICE) are the most common form of heat engines, as they are used in vehicles, boats, ships, airplanes, and trains. They are named as such because the fuel is ignited in order to do work inside the engine. The same fuel and air mixture is then emitted as exhaust.
What are the 3 things that an internal combustion engine needs to run?
Beyond the combustion stroke, which pushes the piston down from the top of the cylinder, there are three other strokes: intake, compression, and exhaust. Engines need air (namely oxygen) to burn fuel.
How many turns does a 4 stroke engine need to make a complete cycle?
A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.
Are rockets external combustion engines?
Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizer, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles.

Is there an external combustion engine?
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.
What is the most important difference between an internal and external combustion engine?
According to the book’s definitions of the two engines, the main difference between the external and internal combustion engine is that the external combustion engine burns fuel outside the engine, and the internal combustion engine burns fuel inside the engine.
What is difference between 2stroke and 4stroke engine?
In a 2-stroke engine, all five functions of the cycle are completed in only two strokes of the piston (or one revolution of the crankshaft). In a 4-stroke engine, the five functions require four strokes of the piston (or two revolutions of the crankshaft).
Which fuel is used in SI engine?
SI engines are commonly fueled on gasoline, with the fuel characterized based on octane number. The octane number defines the fuel’s ability to reduce autoignition or knock, with the higher the octane number, the higher the resistance to autoignition.
