VE Commercial Vehicles Junior Engineer Interview Questions and Answers

There are various types of engines that work based on different principles.

• Engines can be classified based on fuel type, ignition type, and working principle.

• Examples of engine types include gasoline engines, diesel engines, electric motors, and steam engines.

• Engines work by converting fuel into energy, which is then used to power a vehicle or machine.

• The working principle of engines can be internal combustion, externa...read more

Maintenance is the process of keeping equipment in good working condition. Varnier calipers are a type of measuring tool used for precision measurements.

• Maintenance involves regular inspections, repairs, and replacements to prevent breakdowns and ensure optimal performance.

• Types of maintenance include preventive maintenance (scheduled inspections and maintenance), predictive maintenance (using data to predict when main...read more

The braking system is a mechanism that allows a vehicle to slow down or stop by converting kinetic energy into heat.

• The braking system typically consists of components such as brake pads, brake calipers, brake rotors, and brake fluid.

• There are two main types of braking systems: drum brakes and disc brakes.

• Drum brakes use brake shoes that press against the inside of a drum to create friction and slow down the vehicle.

• Di...read more

Current is the flow of electric charge in a circuit, measured in Amperes. Voltage is the electrical potential difference between two points, measured in Volts.

• Current is the rate of flow of electric charge in a circuit

• Voltage is the electrical potential difference between two points

• Current is measured in Amperes (A)

• Voltage is measured in Volts (V)

• Ohm's Law relates current, voltage, and resistance: V = I * R

Earthing is the process of connecting electrical systems to the ground to prevent electric shocks and protect equipment.

• Earthing provides a path for fault currents to flow safely to the ground.

• It helps in stabilizing voltage levels and protecting against lightning strikes.

• Earthing is essential for safety in electrical systems to prevent electric shocks to humans and animals.

• Examples of earthing include grounding rods, ...read more

Two-stroke and four-stroke engines differ in their operation and design.

• Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines complete it in four strokes.

• Two-stroke engines have a simpler design with fewer moving parts, while four-stroke engines are more complex.

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

• Four...read more
