An Internal combustion engine does not require a boiler or other components, thus it is light and compact. Whereas the external combustion engine requires a boiler and other components to transfer energy, thus it is heavy. The internal combustion engine has an efficiency of about 35-45 %.
Why IC engine is more efficient than EC 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 difference between internal and external combustion?
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 is EC engine example?
For example, an external combustion engine would use a flame to heat water into steam, then using the steam to turn a turbine. This is different from internal combustion, like in a car engine, where the gasoline ignites inside a piston, does work, and then is expelled.
What is the main difference between IC engine and steam engine?
|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|
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.
How does EC engine work?
An external combustion engine is a heat engine where an (internal) working fluid is heated by combustion of 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 term of IC engine?
An internal combustion engine (ICE or IC engine) 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.
What is IC engine classification?
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.
Is Steam Engine an IC engine?
Internal combustion engine or steam engine is used to convert heat energy into mechanical energy. I.C Engine and Steam Engine are types of heat engine but the different classes of machines. … Energy produced by the internal combustion engine or steam can be transformed into one form to another.
What is 2 stroke IC engine?
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft.
What is the difference between SI and CI engine?
Difference Between Si engine and Ci engine
Si engine is internal combustion engine that operates on the principle of spark ignition. It uses petrol and utilizes the Otto cycle. The diesel (Ci) engine is also an internal combustion engine, which uses diesel fuel and operates on diesel cycle.
What are the applications of IC engine?
