Latest Mechanical Interview Questions & Answers


What happens if gasoline is used inwards a Diesel engine?Diesel engine volition function ?

No, It volition non work,as the Compression ratio of Petrol engine is half dozen to 10 & that of Diesel engine is xv to 22. Thus on such high compression, gasoline gets highly compressed & it may blast.

Definition of Octane reveal & Cetane number


Octane No.- Octane reveal is defined every bit the percentage, past times volume, of iso octane inwards the mixture of iso octane too h-heptane. It is the mensurate of rating of SI engine.

Cetane No.- Cetane reveal is defined every bit the percentage, past times volume, of n-cetane inwards the mixture of n-cetane too alpha methyl naphthalene. It is the mensurate of rating of CI engine.

Poisons ratio is higher inwards (rubber/steel/wood)

When a cloth is compressed inwards 1 direction, it usuallytends to expand inwards the other 2 directions perpendicular tothe management of compression. This phenomenon is called thePoisson effect. Poisson’s ratio is a mensurate of the Poisson effect.

For prophylactic = 0.5

For steel = 0.288

For forest < 0.2

Thus Poisson’s ratio is higher inwards RUBBER.
