3. Introduction Internal combustion engine vehicle (ICEV) Internal combustion engine vehicle (ICEV) is a vehicle that is powered by a regular internal combustion engine (ICE). ICEV uses fuel which combusts inside a combustion chamber with the help of an oxidizer (typically oxygen from the air). This means that to get power, ICEVs literally burn fuel. ICEs most commonly use fuels derived from fossil fuels. These include petrol, diesel, jet fuel, and compressed natural gas. In addition to internal combustion engines that use fossil fuels, there are also ICEs that are powered by biofuels (e.g., ethanol and biodiesel) or hydrogen. ICE is the most common engine used in cars, planes, boats and other vehicles. But fossil fuel is not a renewable source of energy and due to incomplete combustion of fossil fuels, these engines pollute the air around us. Because of these environmental challenges, car manufacturers are now manufacturing more and more alternatives that do not use or use less fossil fuel. These include electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs) and fuel cell vehicles (FCVs).

4. Classification of I.C Engine Internal combustion engines are engines in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the operating fluid flow circuit. Within an internal combustion engine, the expansion of high-temperature and high-pressure combustion gases, direct force is applied to any part of the engine. Classification Of IC Engine (Internal Combustion Engines) According To Type Of Ignition ( According To Method Of Ignition ) A) SI engine :- A spark-ignition engine (SI engine) is an internal combustion engine, usually a petrol engine, where the combustion cycle of an air-fuel mixture is ignited by a spark plug.

5. Working principle of S.I Engine The fuel from the carburetor used to enter into the combustion chamber at the time of suction stroke by moving the piston downwards by opening the inlet valve and this fuel gets compressed by moving the piston upwards when the piston moves maximum to the top of the cylinder the spark plug produces a spark to ignite the fuel and generates huge power and this power is used to store in the flywheel and reused when it is required and at the time of compression and ignition both the inlet and outlet valves gets closed, after the ignition process the burned fuel develops hot waste gases and this waste gas passes out at the time of exhaust stroke by opening the outlet valve. Suction/Intake Stroke Inlet Valve – Open Outlet Valve ­­ – Closed Crankshaft Rotation – 180° Compression Stroke Inlet Valve – Closed Outlet Valve ­­ – Closed Crankshaft Rotation – 180° (Total 360°) Power/Combustion Stroke Inlet Valve – Closed Outlet Valve ­­ – Closed Crankshaft Rotation – 180°(Total 540°) Exhaust Inlet Valve – Closed Outlet Valve ­­ – Open Crankshaft Rotation – 180° (Total 720°)

6. C.I Engine –Types & Working B) CI Engine :- A CI engine is type of an internal combustion engine in which the fuel charge is ignited by the heat of compression. Clasification of CI Engine- A) Petrol Engine :- The petrol engine (British English) or the gasoline engine (American English) is a spark-ignition internal combustion engine designed to run on petrol ( gasoline) and similar volatile fuels. B) Diesel Engine :- The diesel engine (also known as the compression-ignition or CI engine), named after Rudolf Diesel, is an internal combustion engine in which the ignition of the fuel is caused by the high temperature of the air in the cylinder due to mechanical compression (adiabatic compression)

7. I.C Engine Based On Number Of Strokes 3 . Classification Of IC Engine Based On Number Of Strokes Per Cycle (According To Cycle Of Operation ) A) 2 stroke Engine :- A two-stroke (or two-cycle) engine is a type of internal combustion engine that completes a two-stroke (up and down) power cycle of the piston during a single rotation of the crankshaft. B) 4 stroke Engine :- The four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while rotating the crankshaft.

9. Advantages and Disadvantages of internal combustion engines Advantages of internal combustion engines Size of engine is very less compared to external combustion engines Power to weight ratio is high Very suitable for small power requirement applications Usually more portable than their counterpart external combustion engines Safer to operate Starting time is very less High efficiency than external combustion engine No chances of leakage of working fluids Requires less maintenance Lubricant consumption is less as compared to external combustion engines In case of reciprocating internal combustion overall working temperature is low because peak temperature is reached for only small period of time (only at detonation of fuel). 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 In case of reciprocating internal combustion noise is generated due to detonation of fuel

10. conclusion Internal Combustion are today widely used for transportation, and they are highly successful in their field. Their drivability and durability are resulting in todays locomotion. But we know very well that as it is a combustion engine so it will produce some gases which is not good for the environment. And so this gases are responsible in arising global warming. So, from the present situation of our country related to IC engines based vechile it can be concluded that IC engines have played a great role this years, but its high time to shift to EV. Rather it can be said that the vechiles which carry heavy loads and goods can still run in diesel engines,but private vechiles are needed to be converted to EV. A small decision can create a large impact,lets start with ourselves and shift our private vechiles to EV
