S R Enterprises Oil and Gas Engineer Interview Questions and Answers

The flywheel in an engine is responsible for storing and releasing energy to maintain a consistent rotational speed.

• The flywheel acts as a mechanical energy reservoir, storing energy during the power stroke and releasing it during the compression stroke.

• It helps to maintain a consistent rotational speed by smoothing out variations in torque.

• The flywheel also provides inertia to the engine, helping it to overcome resist...read more

The speed of a turbocharger varies depending on the engine's RPM and the size of the turbocharger.

• The speed of a turbocharger is measured in revolutions per minute (RPM).

• Turbochargers can spin at speeds of up to 200,000 RPM or more.

• The speed of a turbocharger is determined by the exhaust gas flow and the size of the turbine wheel.

• Larger turbochargers generally spin at lower speeds compared to smaller ones.

• The speed of ...read more

Cranking speed is the speed at which an engine turns over during starting.

• It is measured in revolutions per minute (RPM).

• It is important to ensure that the cranking speed is sufficient to start the engine.

• Factors that can affect cranking speed include battery voltage, engine temperature, and engine oil viscosity.

• A low cranking speed can result in slow or failed engine start.

• A high cranking speed can cause damage to the
