Which is part of CI engine?

Exhaust Valve: The whole burnt or exhaust from the cylinder thrown out through exhaust valve. Combustion chamber: It is a chamber where the combustion of fuel takes place. Piston: It is reciprocating part of CI engine which does reciprocating motion inside the cylinder.

Which of the following is not a part of CI engine?

Which of the following does not relate to a compression ignition engine? Explanation: Carburetor is not related to compression ignition engine.

What are the different part of IC engine?

For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.

What are the main parts of a diesel engine?

Which cycle is more efficient?

Explanation: Otto cycle is more efficient than Diesel cycle for a given compression ratio. 6. For constant maximum pressure and heat input, the air standard efficiency of the gas power cycle is in the order.

What is scavenging air?

Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. … Scavenging is equally important for both two-stroke and four-stroke engines.

Why CI engines are mostly used?

The compression ignition engine or diesel engine is the type that has most commonly been used for power generation, particularly in off-grid situations. The engine uses a higher compression ratio than a spark ignition engine to heat air in the engine cylinder.

Is fuel pump used in CI engine?

Early CI engines used air pressure to deliver the fuel into the cylinder, but nowadays liquid fuel, supplied by a reciprocating plunger pump, is delivered through small bore steel pipelines to the injector, which breaks up the fuel to the required degree and deliver it to combustion region in the chamber.
