Radial engine Opposed engine V-Engine Inline engine

Correct Answer: V-Engine

Explanation:

Power is the rate of doing work or workdone per unit time. In S.I. system of units, the unit of power is watt (briefly written as W) which is equal to 1 N-m/s or 1 J/s.

Generally a bigger unit of power called kilowatt (briefly written as kW) is used which is equal to 1000 W.

2) Which is the high fuel efficient engine?

Opposed engine V-Engine Radial engine Inline engine

Correct Answer: Radial engine

3) Which is the engine also called as constant pressure cycle engine?

Otto cycle Diesel cycle Dual cycle Rankave cycle

Correct Answer: Diesel cycle

4) What is called the distance between centre of the crank pin to the centre of the main journal?

Stroke Cycle Throw Efficiency

Correct Answer: Throw

5) How the piston stroke is defined as?

Double the throw Half of the throw Equal to the throw 4 times of throw

Correct Answer: Double the throw

Explanation:

The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected, hence Diesel engines are called compression ignition engines.
A Diesel cycle consists of one constant pressure, one constant volume and two isentropic processes.
