VST Motors Workshop Manager Interview Questions, Process, and Tips

A petrol engine works by igniting a mixture of fuel and air inside a combustion chamber to create controlled explosions that drive the piston.

• Petrol engine uses spark ignition to ignite the fuel-air mixture

• The fuel-air mixture is compressed by the piston inside the combustion chamber

• The spark plug ignites the mixture, causing a controlled explosion

• The explosion pushes the piston down, converting the energy into mechani...read more

Diesel engines work by compressing air and fuel to create combustion, which powers the engine.

• Diesel engines use compression ignition, where the air-fuel mixture is compressed to a high pressure and temperature, causing spontaneous combustion.

• The fuel is injected into the combustion chamber at the end of the compression stroke, and it ignites due to the high temperature.

• The combustion of the fuel creates expanding gase...read more

A hybrid engine combines an internal combustion engine with an electric motor to power a vehicle.

• Hybrid engines use both gasoline and electricity as power sources.

• They are designed to improve fuel efficiency and reduce emissions.

• The electric motor assists the internal combustion engine during acceleration and provides power during low-speed driving.

• Regenerative braking is used to recharge the battery by converting kine...read more

To check diesel engine health, perform visual inspection, check for abnormal noises, monitor exhaust emissions, and conduct diagnostic tests.

• Perform a visual inspection of the engine for any leaks, cracks, or signs of damage.

• Listen for any abnormal noises such as knocking, rattling, or excessive vibration.

• Monitor the exhaust emissions for excessive smoke, unusual smells, or irregularities.

• Conduct diagnostic tests using...read more

Synthetic oil is a man-made lubricant with superior performance and protection compared to conventional engine oil.

• Synthetic oil is chemically engineered to have a more uniform molecular structure, resulting in better lubrication and reduced friction.

• It offers improved viscosity stability, meaning it maintains its thickness and performance in extreme temperatures.

• Synthetic oil provides better protection against engine ...read more
