Working Of 4 Stroke Ci Engine

At this point the suction stroke completes and the suction or inlet valve closes. Compression stroke During the compression stroke the piston starts moving in upward and compresses the air in the clearance volume. While in the case of spark ignition SI engines, the compression ratio is about 6-10, the CI engine this ratio is about 16-20.

The diesel engine is also known as the compression ignition engine CI engine. The four stroke diesel engine is based on the diesel cycle invented by Rudolf diesel auto in 1895. Single cylinder 4-stroke engine working can be understood by knowing the process which consists of 4 number of strokes. The engine does two cycles

One of the most useful engine is a four stroke engine which is mostly used in automobile industries. These engines can be further classified into spark ignition engine or petrol engine and compression ignition engine or diesel engine. The SI engine is developed by Nicolaus Otto and CI engine is developed by Rudolf Diesel.

The piston moves from BDC to TDC to compress the air. In case of CI engine, the compression ratio varies from 12 to 18. The pressure at the end of compression is about 3500 to 4000 kN m2. The temperature of the compressed air reaches 600 to 700C . 3. Power Stroke In this stroke also, both the inlet and exhaust valves are in closed position.

Its working is also divided into 4 strokes. Here we are discussing the working of four four-stroke CI engine. 1. Suction stroke The suction of air into the cylinder takes place. 2. Compression stroke The compression of air happens in this stroke. 3. Power stroke Ignition and combustion of fuel. 4. Exhaust stroke Escaping of burnt or exhaust

Working principle of CI engine In four-stroke cycle engines there are four strokes completing two revolutions of the crankshaft. These are respectively The suction, Compression, Power and Exhaust strokes. Fig P-V diagram of CI Engine Suction stroke In suction stroke, inlet valve is opened and exhaust valve is closed.

Working principle of CI engine Suction stroke During this stroke, inlet valve is open and exhaust valve is closed.Only air is sucked into cylinder during this stroke. The piston moves from TDC to BDC and crank shaft rotates through 180. Compression Stroke The air inducted in the cylinder is compressed to the clearance volume. Both the

For CI engine the compression ratio is about 16 to 20. The fuel is injected into the cylinder at the end of compression stroke. The temperature at the end of compression is very high enough to self-ignite the fuel that is the reason this engine called compression ignition engine. Combustion Expansion stroke or Power stroke Process 23 and

The full form of the CI engine is a compression ignition engine. A CI engine is an internal combustion engine where the use of hot compressed air ignites the fuel. When air is compressed, heat is created, which is used to ignite and burn the fuel. In this engine, the suction stroke draws air in, which is then compressed during the compression
