Maruti Suzuki Assembly Technician Interview Questions and Answers

The ratio of petrol refers to the proportion of petrol in a mixture or fuel.

• The ratio of petrol is typically expressed as a fraction or percentage.

• For example, a fuel mixture with a petrol ratio of 1:4 means that for every 1 part of petrol, there are 4 parts of other components.

• The petrol ratio can vary depending on the specific fuel blend or application.

• It is important to maintain the correct petrol ratio for optimal ...read more

CRDI and MPFI are fuel injection systems used in automobiles. CRDI is used in diesel engines while MPFI is used in petrol engines.

• CRDI stands for Common Rail Direct Injection and MPFI stands for Multi-Point Fuel Injection.

• CRDI injects fuel directly into the engine cylinder while MPFI injects fuel into the intake manifold.

• CRDI is more efficient and provides better fuel economy than MPFI.

• CRDI is used in diesel engines wh...read more

To work TDC to BDC, rotate the crankshaft until the piston is at top dead center (TDC) and then rotate it in the direction of engine rotation until it reaches bottom dead center (BDC).

• Locate the timing marks on the crankshaft pulley and the timing cover

• Rotate the crankshaft until the timing mark on the pulley aligns with the TDC mark on the cover

Petrol engines use spark plugs to ignite fuel, while diesel engines use compression to ignite fuel.

• Petrol engines use spark plugs to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.

• Petrol engines are generally lighter and more responsive, while diesel engines are more fuel efficient and have higher torque.

• Petrol engines are more common in cars and motorcycles, while diesel engin...read more

Series parallel connection in automobiles allows for efficient power distribution and redundancy.

• Series connection allows for higher voltage output, which is needed for certain components like headlights.

• Parallel connection ensures redundancy and reliability in case one component fails.

• Combining series and parallel connections optimizes power distribution in automobiles.

• Example: Series connection for battery cells, par

The firing order of a 4 cylinder engine is typically 1-3-4-2.

• The firing order refers to the sequence in which each cylinder in the engine fires.

• In a 4 cylinder engine, the firing order is usually 1-3-4-2.

• This means that cylinder 1 fires first, followed by cylinder 3, then cylinder 4, and finally cylinder 2.

Air conditioning is a system that cools and dehumidifies air in a space to provide comfort and improve air quality.

• Air conditioning systems use refrigerants to absorb and release heat, cooling the air in the process.

• They consist of components such as compressors, condensers, evaporators, and expansion valves.

• Air conditioning can be central (whole-house) or individual units (window or portable).

• Regular maintenance is im...read more
