AML RightSource Interview Questions and Answers

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 wear, oxidation, and sludge buildup.

• It has a longer lifesp...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 specialized equipment to analyze engine performance, fuel...read more

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 mechanical work

• The piston movement turns the crankshaft, which dr...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 gases that push the piston down, converting the linear motion ...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 kinetic energy into electrical energy.

• Examples of hybrid vehic...read more
