Preet Group Interview Questions and Answers

The cost of Ceria bed used in the design of a catalytic converter is lower than the bed used in available catalytic converters.

• Ceria is a cost-effective material for catalytic converters.

• It is widely used in the automotive industry due to its affordability.

• Compared to other beds used in catalytic converters, Ceria offers a more economical solution.

• The lower cost of Ceria bed does not compromise the performance of the catalytic converter.

The rectangle will have greater load bearing capacity in the vertical position.

• The load bearing capacity of a rectangle depends on its orientation.

• In the vertical position, the weight is distributed along the longer side, resulting in greater load bearing capacity.

• In the horizontal position, the weight is distributed along the shorter side, resulting in lower load bearing capacity.

• The vertical position allows for better weight distribution and stability.

• Examples: A bookshelf ...read more

I would choose Design over Testing.

• Design allows for creativity and innovation.

• Design involves problem-solving and critical thinking.

• Design offers the opportunity to create new products or improve existing ones.

• Design requires collaboration and communication with cross-functional teams.

• Design offers long-term career growth and advancement opportunities.

The inlet valve is opened before TDC to allow fresh air-fuel mixture into the combustion chamber. The spark plug is positioned at a specific angle for efficient combustion.

• Opening the inlet valve before TDC ensures that the piston is moving downwards, creating a pressure difference that helps in drawing the air-fuel mixture into the combustion chamber.

• This timing also allows for better mixing of the air and fuel, leading to improved combustion efficiency.

• The spark plug is pos...read more

Changing the angle can have various effects depending on the context.

• Changing the angle can alter the direction or trajectory of a moving object.

• In physics, changing the angle of incidence can affect the amount of reflection or refraction of light.

• In engineering, changing the angle of a structural component can affect its stability or load-bearing capacity.

• In mathematics, changing the angle can affect the trigonometric functions and their values.

• In sports, changing the angle ...read more

A S.I./C.I. engine is a type of internal combustion engine that operates on either spark ignition or compression ignition.

• S.I. engine stands for Spark Ignition engine, where the fuel-air mixture is ignited by a spark plug.

• C.I. engine stands for Compression Ignition engine, where the fuel-air mixture is ignited by the heat of compression.

• In a S.I. engine, the fuel-air mixture is drawn into the cylinder during the intake stroke, compressed during the compression stroke, ignited...read more
