Isuzu Motors Production Engineer Interview Questions and Answers

The ratio of air to fuel to start an engine is typically around 14.7:1.

• The ideal air-fuel ratio for starting an engine is known as the stoichiometric ratio, which is around 14.7 parts air to 1 part fuel.

• This ratio ensures complete combustion of the fuel and optimal engine performance.

• Different types of engines may require slightly different air-fuel ratios for starting, but 14.7:1 is a common standard.

Power is transferred to the wheels through the drivetrain system, which includes components like the engine, transmission, driveshaft, differential, and axles.

• Power is generated by the engine, typically through combustion of fuel.

• The transmission transfers power from the engine to the driveshaft.

• The driveshaft sends power to the differential, which then distributes it to the axles.

• The axles rotate the wheels, propellin...read more

Jigs are used to guide tools and hold workpieces in place, while fixtures are used to hold workpieces in a specific position during machining.

• Jigs are used to guide cutting tools, while fixtures are used to hold workpieces in place.

• Jigs are typically used for drilling, reaming, and tapping operations, while fixtures are used for milling, grinding, and turning operations.

• Jigs are often more complex and expensive than fi...read more

A 4 stroke engine is an internal combustion engine that completes four separate strokes - intake, compression, power, and exhaust - in two crankshaft revolutions.

• Intake stroke: Fuel and air are drawn into the combustion chamber.

• Compression stroke: The fuel-air mixture is compressed by the piston.

• Power stroke: The spark plug ignites the mixture, causing an explosion that drives the piston down.

• Exhaust stroke: The piston...read more
