Royal Enfield Mechanical Technician Interview Questions and Answers

On-Board Diagnostics

• On-Board Diagnostics (OBD) is a system in vehicles that monitors the performance of the engine and emissions systems.

• It helps to identify issues and malfunctions by providing codes that can be read with a diagnostic tool.

• OBD systems have evolved over the years, with OBD-II being the current standard in most vehicles.

• Examples of OBD codes include P0300 for random misfire and P0420 for catalytic conve

An engine is the power source of a vehicle that converts fuel into mechanical energy.

• An engine is a complex machine that converts fuel into mechanical energy to power a vehicle.

• It consists of various components such as cylinders, pistons, crankshaft, and camshaft.

• There are different types of engines such as gasoline, diesel, electric, and hybrid.

• Regular maintenance and proper care are essential for the engine's longevi

DOC stands for Diesel Oxidation Catalyst, a device used to reduce harmful emissions in diesel engines. Mufflers are components that reduce noise produced by the engine.

• DOC is a device used in diesel engines to convert harmful pollutants into less harmful substances.

• Mufflers are components in the exhaust system that reduce noise produced by the engine.

• DOCs are commonly used in vehicles to meet emission standards.

Starting & presser pipe is a term used in mechanical engineering to refer to pipes used for starting and pressurizing systems.

• Starting pipe is used to supply initial fluid or gas to start a system

• Presser pipe is used to maintain pressure in a system

• Examples include starting and presser pipes in hydraulic systems or pneumatic systems

The question is likely asking about the use of AC gas in air conditioning systems.

• AC gas is used in air conditioning systems to cool the air.

• The AC gas circulates through the system, absorbing heat from the indoor air and releasing it outside.

• Common types of AC gases include R-410A and R-22.

• Proper handling and disposal of AC gas is important to prevent harm to the environment.

The question seems to be asking about the use of AC gas in servicing AC units.

• AC gas is used in air conditioning systems to cool the air.

• Regular servicing of AC units involves checking and refilling AC gas if needed.

• Improper handling of AC gas can be harmful to the environment and human health.

The question seems to be asking about servicing and maintenance of air conditioning systems.

• AC service involves cleaning, inspecting, and repairing air conditioning units to ensure they function properly.

• AC feet refers to the proper placement and leveling of the air conditioning unit to ensure optimal performance.

• AC change may refer to changing air filters regularly to maintain air quality and efficiency.

• AC gas use inv...read more

Shock absorbers are devices used to dampen the vibrations and shocks in mechanical systems.

• Hydraulic shock absorbers use fluid to absorb and dissipate energy.

• Pneumatic shock absorbers use air or gas to absorb and dissipate energy.

• Gas-filled shock absorbers use pressurized gas to absorb and dissipate energy.

• Electromagnetic shock absorbers use electromagnetic fields to control damping.

• Friction shock absorbers use frictio...read more

Three types of shock absorbers are hydraulic, pneumatic, and spring-loaded.

• Hydraulic shock absorbers use fluid to dampen vibrations and shocks.

• Pneumatic shock absorbers use air or gas to absorb shocks.

• Spring-loaded shock absorbers use springs to absorb shocks and vibrations.
