IBM Interview Questions and Answers

A diesel engine functions by compressing air in the cylinder, injecting fuel, and igniting the fuel-air mixture to create combustion.

• Diesel engines compress air in the cylinder to high pressures, typically around 15:1 compression ratio.

• Fuel is injected into the cylinder at the end of the compression stroke.

• The fuel is ignited by the heat generated from the high compression, not by a spark plug like in gasoline engines.

• The combustion of the fuel-air mixture creates high pressu...read more

Gears are mechanical devices that transmit motion and power between rotating shafts. Types include spur, helical, bevel, worm, rack and pinion.

• Spur gears have straight teeth and are the most common type

• Helical gears have angled teeth for smoother operation

• Bevel gears have cone-shaped teeth for changing direction of rotation

• Worm gears have a screw-like appearance and are used for high torque applications

• Rack and pinion gears convert rotational motion into linear motion

Diesel is heavier and less volatile than petrol, leading to differences in combustion, efficiency, and emissions.

• Diesel is heavier and less volatile than petrol

• Diesel engines compress air to ignite fuel, while petrol engines use spark plugs

• Diesel engines are more fuel-efficient but produce more emissions

• Petrol engines are quieter and faster than diesel engines
