Shriram Pistons & Rings Senior Engineer Interview Questions, Process, and Tips

Adding petrol in diesel engine or vice versa can cause serious damage to the engine.

• Petrol in diesel engine can cause damage to fuel pump and injectors

• Diesel in petrol engine can cause damage to spark plugs and catalytic converter

• It is important to drain the fuel tank and flush the system if wrong fuel is added

• Prevention is better than cure, always double check before refueling

Fe-C equilibrium diagram shows the phases of iron-carbon alloys at different temperatures and compositions. Eutectic alloy is 4.3% carbon.

• Fe-C equilibrium diagram is a graphical representation of the phases of iron-carbon alloys at different temperatures and compositions.

• It shows the transformation of austenite to ferrite and cementite as the carbon content decreases.

• Eutectic alloy is the composition at which the liqui...read more

Hardness is the resistance of a material to indentation, while toughness is the ability of a material to absorb energy without fracturing.

• Hardness is a measure of a material's ability to resist deformation under an applied force.

• Toughness is a measure of a material's ability to absorb energy before fracturing.

• Hardness is often measured using the Mohs scale, while toughness is measured using impact tests.

• A diamond is ve...read more

Diesel engines have higher compression ratios and are more fuel-efficient than gasoline engines.

• Diesel engines compress air to a higher degree than gasoline engines, resulting in higher compression ratios.

• Higher compression ratios lead to better fuel efficiency and more power.

• Gasoline engines use spark plugs to ignite the fuel, while diesel engines use compression to ignite the fuel.

• Diesel engines are typically more ex
