Ather Energy Interview Questions, Process, and Tips

Two stroke engines have a power stroke every revolution, while four stroke engines have a power stroke every other revolution.

• Two stroke engines have a simpler design with fewer moving parts.

• Four stroke engines are more fuel efficient and produce less pollution.

• Examples: Two stroke engines are commonly found in chainsaws and dirt bikes, while four stroke engines are used in cars and motorcycles.

Air fuel ratio of diesel engine is the ratio of air to fuel in the combustion process.

• Air fuel ratio is typically around 14:1 for diesel engines.

• Optimal air fuel ratio ensures efficient combustion and engine performance.

• Lean air fuel mixture (more air, less fuel) can improve fuel efficiency but may lead to higher NOx emissions.

• Rich air fuel mixture (more fuel, less air) can improve power output but may lead to higher e...read more

The alternator is a crucial component in a car's electrical system, responsible for charging the battery and powering the electrical components while the engine is running.

• Converts mechanical energy from the engine into electrical energy to charge the battery

• Powers the electrical components of the car while the engine is running

• Regulates the voltage to ensure a consistent power supply

• Typically located near the front of...read more

The alternator in a car is responsible for converting mechanical energy into electrical energy to power the vehicle's electrical systems.

• The alternator charges the battery while the engine is running

• It powers the electrical components of the car such as the lights, radio, and air conditioning

• If the alternator fails, the car may not start or the battery may die

• Common signs of alternator issues include dimming lights, st

The differential in a vehicle allows the wheels to rotate at different speeds while maintaining traction.

• Differential is a gear train that allows the wheels on an axle to rotate at different speeds.

• It is necessary because the inner and outer wheels of a vehicle turn at different speeds when going around a corner.

• There are different types of differentials such as open, limited-slip, and locking differentials.

• Open differ...read more
