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. … After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion.
What is the use of IC engine?
IC engine is a heat engine where the combustion of the air-fuel mixture occurs inside the combustion chamber that produces high temperature and high gas pressure. This gas pressure pushes the piston over a distance and transforms the chemical energy into thermal energy which is used for performing the mechanical work.
How are IC engines are classified?
We can classify internal combustion reciprocating engines according to the number of strokes of the piston in one complete working cycle. … There is still another classification according to the process of combustion: explosion or constant-volume combustion engines and constant-pressure combustion or Diesel engines.
How many types of IC engines are there?
There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine.
What are the measures of IC engine performance?
Basic design and performance parameters in internal combustion engines include compression ratio, swept volume, clearance volume, power output, indicated power, thermal efficiency, indicated mean effective pressure, brake mean effective pressure, specific fuel consumption, and more.
Which fuel is used in IC engine?
Gasolines are the main fuel for spark-ignition internal combustion engines (Otto engines), diesel fuels are for compression ignition internal combustion engines (diesel engines), marine fuels are for shipping, and aviation turbine fuels (JET fuels) are used for aviation turbines.
What are the advantages of lubrication in IC engine?
(c) It minimizes power loss due to friction. (d) It provides cooling effect. While lubricating it also carries some heat from the moving parts and delivers it to the surroundings through the bottom of the engine (crank case). (e) It helps reduce noise created by the moving parts.
