Maruti Suzuki Diploma Automobile Engineer Interview Questions and Answers

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

• Two-stroke engines have a simpler design and are lighter than four-stroke engines.

• Two-stroke engines have a higher power-to-weight ratio but lower fuel efficiency compared to four-stroke engines.

• Four-stroke engines have separate intake, compression, power, and exhaust strokes, while two-stro...read more

A pictorial representation of a SI engine with valve opening, TDC, and BDC.

• SI engine stands for Spark Ignition engine, which is commonly used in gasoline-powered vehicles.

• Valve opening refers to the movement of the intake and exhaust valves to allow fuel-air mixture in and exhaust gases out of the combustion chamber.

• TDC (Top Dead Center) is the position of the piston at the extreme top of its stroke.

• BDC (Bottom Dead Ce...read more

A circuit breaker is an electrical switch that automatically interrupts the flow of current when it exceeds a certain limit.

• It is used to protect electrical circuits from damage caused by overloading or short circuits.

• It works by detecting the excess current and tripping the switch to break the circuit.

• It can be reset manually or automatically depending on the type of circuit breaker.

• Examples include thermal circuit br...read more

A contactor is an electrical switch used for switching an electrical circuit on or off.

• It is used to control electric motors, lighting, heating, and other electrical loads.

• It consists of a coil, contacts, and an enclosure.

• The coil generates a magnetic field that pulls the contacts together to close the circuit.

• Examples include HVAC systems, elevators, and industrial machinery.

• Contactor ratings are based on the amount o...read more

MCB stands for Miniature Circuit Breaker. It is an electrical switch that automatically shuts off the electrical circuit during an overload or short circuit.

• MCB is a type of circuit breaker that is commonly used in residential and commercial buildings.

• It is designed to protect electrical circuits from damage caused by overloading or short circuits.

• MCBs are available in different current ratings and can be easily replac...read more

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.

• There are different types of motors such as DC motors, AC motors, stepper motors, and servo motors.

• The basic principle of a motor is the interaction between a magnetic field and an electric current.

• Examples of motor...read more

A current transformer is a device that measures the current flowing in a circuit by producing a proportional current in its secondary winding.

• Consists of a primary winding and a secondary winding

• Primary winding is connected in series with the circuit carrying the current to be measured

• Secondary winding is connected to a measuring instrument or protective relay

• Produces a current in the secondary winding that is proporti...read more
