Aisan Industry Interview Questions, Process, and Tips

The fuel pump is responsible for delivering fuel from the gas tank to the engine at the correct pressure.

• The fuel pump is typically located inside the fuel tank.

• It is powered by electricity and uses a diaphragm or impeller to create pressure.

• The fuel pump ensures that the engine receives the right amount of fuel for combustion.

• Issues with the fuel pump can lead to poor engine performance or stalling.

• Regular maintenance...read more

Fuel injectors play a crucial role in controlling the fuel flow rate in an engine, measured in feet per minute (fpm).

• Fuel injectors are responsible for delivering the right amount of fuel to the engine cylinders at the right time.

• The flow rate of fuel through the injectors is measured in feet per minute (fpm) to ensure optimal engine performance.

• Correlation between fuel injector performance and fpm can indicate efficie...read more

Maximum material condition (MMC) is a term used in engineering to describe the condition of a part when it contains the maximum amount of material allowed by its design specifications.

• MMC is the condition where a part has the maximum amount of material within the specified limits.

• It is used to ensure proper fit and function of mating parts.

• GD&T symbols are used to indicate MMC on engineering drawings.

• For example, a hol...read more

Lest material condition refers to the worst possible condition that a material can be in without being rejected.

• Lest material condition is used to establish the minimum acceptable quality level for a material.

• It helps in determining the point at which a material should be rejected due to poor quality.

• Examples include maximum allowable defects in a material or minimum strength requirements.

A vernier caliper is a precision measuring tool used to measure internal and external dimensions with high accuracy.

• Consists of two main parts - the main scale and the vernier scale

• The main scale is fixed and has markings in millimeters or inches

• The vernier scale slides along the main scale and provides more precise measurements

• Other parts include the jaws (for measuring external dimensions), the depth gauge (for measu...read more
