Maruti Suzuki Automobile Engineer Interview Questions, Process, and Tips

A 2-stroke engine completes a power cycle in two strokes of the piston, while a 4-stroke engine completes it in four strokes.

• 2-stroke engine: Combustion occurs every revolution of the crankshaft.

• 4-stroke engine: Combustion occurs every two revolutions of the crankshaft.

• 2-stroke engines are simpler, lighter, and have higher power-to-weight ratio.

• 4-stroke engines are more fuel-efficient and have better emissions control.

An automobile engine is a device that converts fuel into mechanical energy to power the vehicle.

• An automobile engine is the heart of a vehicle, responsible for generating power to propel the vehicle forward.

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

• There are different types of automobile engines, such as gasoline engines, diesel engines, and electric moto...read more

4 stroke engines are used in automobiles for their efficiency, power output, and reduced emissions.

• 4 stroke engines provide better fuel efficiency compared to 2 stroke engines.

• They have a higher power output due to separate intake, compression, power, and exhaust strokes.

• 4 stroke engines produce fewer emissions as they have a dedicated exhaust stroke.

• Examples of automobiles using 4 stroke engines include cars, trucks,

2 stroke engines are not commonly used due to their higher emissions, lower fuel efficiency, and shorter lifespan.

• 2 stroke engines produce more emissions compared to 4 stroke engines.

• They have lower fuel efficiency as they consume more fuel per power stroke.

• The lubrication system in 2 stroke engines is less effective, leading to shorter engine lifespan.

• Examples of vehicles that still use 2 stroke engines include some m

A hybrid engine vehicle is a vehicle that combines two or more power sources, typically an internal combustion engine and an electric motor.

• Hybrid vehicles use regenerative braking to recharge their batteries.

• They can operate on either the internal combustion engine, the electric motor, or both.

• Hybrid engines improve fuel efficiency and reduce emissions.

• Examples of hybrid vehicles include the Toyota Prius, Honda Insigh

BS stands for Bharat Stage, which is the emission standards set by the Indian government for vehicles.

• BS standards are used to regulate the emission of pollutants from vehicles in India.

• These standards are based on European emission standards and are implemented in a phased manner.

• Each stage of BS standards sets stricter limits on the emission of pollutants such as carbon monoxide, nitrogen oxides, and particulate matt...read more
