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

Which of the following is a component of CI engine?

Main Components of Compression Ignition 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 is not used in CI engine?

Which engine is not used in CI? Explanation: Methanol is not used in CI engines because of its high octane number and low cetane number. Pure methanol and gasoline in various percentages have been extensively tested in engines and vehicles for a number of years.

Which of the following is not an IC engine part Mcq?

What are engine components made of?

However, the main materials used for engine parts are iron base alloys such as structural steels, stainless steels, iron base sintered metals, and cast iron and aluminum alloy parts for the piston, cylinder head and cylinder block.

Which is not a part of petrol engine?


SI engine (Petrol Engine) CI engine (Diesel Engine)
Engine weight is less. Engine weight is more.
Small in size therefore less space occupied Large in size therefore more space occupied
It emits carbon monoxide. (CO) It emits carbon dioxide. (CO2)

Why petrol is not used in CI engines?

Gasoline can’t be used because it needs compression ration of 8-10 and CI engines are designed to have compression ration above 18. So when gasoline is fed, it will automatically burn and hence create a blast way below the TDC of crank.

Why spark plug is not used in CI engines?

Air heats up as it is compressed. Squeeze enough of it quickly enough within an engine cylinder and the temperature and environment will be just right for it to ignite fuel without the need of a spark. This is what happens in a diesel engine.

Which of the following is used in CI engines Mcq?

Explanation: Platinum and palladium are only the two main catalyst materials that are used for converters on CI engines.

Which of the following are the examples of IC engine?

Internal-combustion engines are the most broadly applied and widely used power-generating devices currently in existence. Examples include gasoline engines, diesel engines, gas-turbine engines, and rocket-propulsion systems.

What is swirl in CI engine Mcq?

Solution: In compression ignition engines, swirl denotes a Rotary motion of the gases in the chamber. In compression ignition engines, swirl denotes a rotary motion of the gases in the chamber as swirl is always related to rotary motion.

What is SI and CI engine?

Definition of 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.

How many components are in an engine?

A typical internal combustion engine has around 200 parts that need to be maintained and possibly replaced if they wear out. An electric vehicle takes that number down to around 20 parts.

What are the basic types of IC engine?

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.
