Which is better internal or external combustion engine?

Which is better internal or external combustion engine?

In IC engines, the combustion of fuel takes place inside, whereas in EC engines the fuel combustion takes place outside the cylinder. The advantages of IC engine are higher BTE, more horsepower developed per unit weight and low cost compared to that of external combustion engine.

What is the main difference between steam engines and internal combustion engines?

Whereas steam engines first combust a fuel to heat water—a process that produces the steam that transmits the energy used to power the engine—internal combustion engines convert the heat energy of the fuel into mechanical power directly.

How are internal combustion engines different from external combustion engines quizlet?

An internal combustion engine is an engine that generates heat energy from the combustion of a fuel inside the engine (ex. gasoline engine), whereas external combustion engines are engines that generate heat energy from the combustion of a fuel outside of the engine (ex. steam engine).

What is the main advantage of external combustion engines over internal combustion 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.

Is diesel engine an internal combustion?

Diesel vehicles are similar to gasoline vehicles because they both use internal combustion engines. In a compression-ignited system, the diesel fuel is injected into the combustion chamber of the engine and ignited by the high temperatures achieved when the gas is compressed by the engine piston.

What is the main difference between internal combustion?

Comparison Chart

I.C. Engine	E.C. Engine
Combustion of fuel takes place inside the cylinder	Combustion of fuel takes place outside the cylinder
Working fluid may be Petrol, Diesel & Various types of gases	Working fluid is steam
Require less space	Require large space
Capital cost is relatively low	Capital cost is relatively high

What is the two types of internal combustion engine and explain their difference?

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. The expansion of the combustion gases pushes the piston during the power stroke. In a diesel engine, only air is inducted into the engine and then compressed.

Which is external combustion engine?

An external combustion engine (EC engine) is a reciprocating 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 kind of engine is an internal combustion engine quizlet?

an internal combustion engine in which the piston completes four separate strokes which constitute a single thermodynamic cycle. The four strokes are: intake, compression, power, and exhaust.

Why is it important for an internal combustion engine to have a cooling system?

The cooling system serves three important functions. First, it removes excess heat from the engine; second, it maintains the engine operating temperature where it works most efficiently; and finally, it brings the engine up to the right operating temperature as quickly as possible.

What are disadvantages of external combustion engines?

Disadvantages of external combustion engines

• Not suitable for low load requirements.
• Leakage of working fluid.
• Lubricant consumption.
• Size of engine is relatively big.
• Overall working temperature is high so great care and special building materials are required.

What are the disadvantages of IC engine?

Disadvantages of internal combustion engines

• Variety of fuels that can be used is limited to very fine quality gaseous and liquid fuel.
• Fuel used is very costly like gasoline or diesel.
• Engine emissions are generally high compared to external combustion engine.
• Not suitable of large scale power generation.

What is the difference between an internal and external combustion 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.

What are the different types of internal combustion engines?

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. Most of these are four-stroke cycle engines, meaning four piston strokes are needed to complete a cycle.

What engine 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. Henry Ford’s iron-wheeled “Fordson” was unveiled in 1907 and powered by an internal-combustion engine.

What are the disadvantages of internal combustion engines?

Disadvantages of internal combustion engines. Variety of fuels that can be used is limited to very fine quality gaseous and liquid fuel. Fuel used is very costly like gasoline or diesel. Engine emissions are generally high compared to external combustion engine. Not suitable of large scale power generation.
