Roca Bathroom Products Interview Questions and Answers

A turbocharger is a device that increases an engine's power output by forcing extra air into the combustion chamber.

• A turbocharger consists of a turbine and a compressor connected by a shaft.

• Exhaust gases spin the turbine, which in turn spins the compressor to force more air into the engine.

• This extra air allows more fuel to be burned, resulting in increased power output.

• Turbochargers are commonly used in high-performance vehicles and diesel engines.

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

• Petrol engines use spark plugs to ignite a mixture of fuel and air, while diesel engines rely on compression to ignite the fuel

• Petrol engines typically have higher RPMs and are more suitable for high-speed driving, while diesel engines have more torque and are better for towing and hauling

• Petrol engines are generally quieter and smoother running compared to diesel engines

The grade of oil to use in an engine is determined by the manufacturer's recommendations based on factors such as engine design, operating conditions, and climate.

• Check the owner's manual for the manufacturer's recommended oil grade

• Consider factors such as engine design, operating conditions, and climate when selecting oil grade

• Consult with a mechanic or oil specialist for guidance if unsure

The operating capacity of the engine is determined by factors such as horsepower, torque, and fuel efficiency.

• The operating capacity of an engine is typically measured in horsepower (HP) or kilowatts (kW).

• Torque is also an important factor in determining the engine's ability to perform under load.

• Fuel efficiency can impact the overall operating capacity of the engine, as a more efficient engine may be able to produce more power with less fuel consumption.

The cooling system in an engine circulates coolant through the engine to absorb heat and dissipate it through the radiator.

• Coolant is pumped through the engine block and cylinder head to absorb heat generated by combustion.

• The heated coolant then flows to the radiator where it releases heat to the surrounding air.

• The radiator fan helps to cool the coolant by blowing air through the radiator fins.

• The cooled coolant is then circulated back to the engine to repeat the process.

A diesel engine is an internal combustion engine that uses compression ignition to burn fuel.

• Diesel engines are commonly used in heavy-duty vehicles like trucks and buses.

• They are more fuel-efficient than gasoline engines and produce less carbon dioxide emissions.

• Diesel engines have a higher compression ratio than gasoline engines, which allows them to generate more power.

• They are also known for their durability and longevity.

• Common diesel engine manufacturers include Cummins...read more
