You asked: Which is part of CI engine?

Which is not 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 Types in CI engine?


  • A) FOUR-STROKE CYCLE ENGINE: This engine makes four piston strokes i.e. intake, compression, power and exhaust to complete an operating cycle. …
  • B) …
  • B)

What is main part of IC engine?

Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston. It is in direct contact with the products of combustion so it must be cooled.

Which one of the following is used in CI engine?

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

Is the reciprocating part of IC engine?

The diesel is an internal combustion reciprocating engine which operates in the compression ignition cycle. The familiar reciprocating mechanism consists of a number of pistons, each running in a gas-tight cylinder with connecting rod and crankshaft.

Which engine has carburetor?

In petrol engine combustion takes place when a mixture of air and fuel gets spark from spark plug (spark initiates fuel burning). This mixture of air and fuel is carburetor. Hence a petrol engine is also known as spark ignition engine, since a spark is used to burn a mixture of air and petrol (or gasoline).

What is the meaning of CI engine?

Compression ignition (CI) engines

In a compression ignition engine only air or air plus residual combustion gases from the exhaust known as exhaust gas recirculation (EGR) is inducted into the chamber during the intake stroke, and compressed during the compression stroke.

What is flame front propagation?

Flame propagation is defined as the progress (spread) of the flame inside the engine cylinder (combustible environment) outward from the point at which the combustion started. Flame generally propagates spherically. The rate of radial propagation of flame is known as flame speed. It is typically measured in m/s.

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.

What is IC and CI engine?

Combustion in IC engines may be intermittent or continuous. IC engines with intermittent combustion are spark ignition (SI) gasoline and compression ignition (CI) diesel engines. Most are four-stroke engines including four distinctive processes, viz., intake, compression (and combustion), power, and exhaust stroke.

Why are diesel engines called CI?

Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark.

What are the 7 engine components?

  • Crankcase or Oil Pan.

What is cylinder in IC engine?

Internal combustion engines

The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber.

Which is used in CL engine?

ICEs are typically powered by fossil fuels like natural gas or petroleum products such as gasoline, diesel fuel or fuel oil. Renewable fuels like biodiesel are used in compression ignition (CI) engines and bioethanol or ETBE (ethyl tert-butyl ether) produced from bioethanol in spark ignition (SI) engines.

Which part of the IC engine transmit force from the piston to the crankshaft?

A connecting rod is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston.

What are the phases of CI engine combustion?

(iv) After Burning Page 9 • Combustion in CI Engines • Thus, it is seen that the complete combustion in CI engines may be comprising of four distinct phases i.e. ‘ignition delay’ followed by ‘uncontrolled combustion,’ ‘controlled combustion’ and ‘after burning’.
