Diploma Engineering Training Interview Questions and Answers

Two-stroke engines have a simpler design and produce more power, but are less fuel-efficient and emit more pollution compared to four-stroke engines.

• Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines complete it in four strokes.

• Two-stroke engines have a simpler design with fewer moving parts, making them lighter and more compact.

• Four-stroke engines have separate intake, compression, power, and exhaust strokes, resulting in better...read more

Petrol and diesel engines differ in fuel type, ignition process, compression ratio, and efficiency.

• Fuel type: Petrol engines use gasoline while diesel engines use diesel fuel.

• Ignition process: Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines use compression ignition.

• Compression ratio: Diesel engines have higher compression ratios than petrol engines.

• Efficiency: Diesel engines are generally more fuel-efficient than petrol engines.

• Examples: Pe...read more

Knowledge of paint refers to understanding the properties, types, application techniques, and safety precautions associated with paints and coatings.

IC engine is an internal combustion engine that converts chemical energy into mechanical energy.

• IC engine works on the principle of internal combustion, where fuel is burned inside the engine to produce power.

• It consists of four strokes: intake, compression, combustion, and exhaust.

• During the intake stroke, the fuel-air mixture is drawn into the cylinder.

• In the compression stroke, the mixture is compressed to increase its pressure and temperature.

• The combustion stroke involve...read more
