Swirl in engine refers to the rotational motion of air or fuel mixture inside the combustion chamber, improving combustion efficiency.
Swirl helps in better mixing of air and fuel, leading to more efficient combustion.
It can improve fuel economy and reduce emissions.
Examples include swirl-inducing intake ports or valves in engines.
Symptom of piston seizure due to lubrication system failure is engine overheating and loss of power.
Engine overheating
Loss of power
Increased engine noise
Visible damage to piston or cylinder walls
Squish in engine refers to the process of compressing the air-fuel mixture in the combustion chamber before ignition.
Squish helps in creating turbulence for better mixing of air and fuel
It also helps in increasing the efficiency of combustion
Squish is achieved by the design of the combustion chamber and piston crown
Thermostat regulates the flow of coolant in the engine cooling system to maintain optimal operating temperature.
Thermostat opens and closes to control the flow of coolant through the radiator.
Helps maintain the engine at its optimal operating temperature for efficiency and performance.
Prevents overheating by regulating the coolant flow based on the engine temperature.
Common issues include thermostat getting stuck close...
Pistons seize when lubrication and cooling systems fail, causing friction and heat buildup.
Pistons rely on lubrication to reduce friction between moving parts
Cooling system prevents overheating by circulating coolant around the engine
Without proper lubrication, friction increases and can cause the piston to seize
If the cooling system fails, heat buildup can also lead to piston seizure
The radiator cap helps regulate the pressure in the cooling system of a vehicle.
Prevents coolant from boiling over by raising the boiling point
Maintains the proper pressure in the cooling system
Allows excess coolant to flow into the overflow tank and back into the radiator when needed
Clamp load is the force applied to hold the clutch plates together, while release load is the force needed to disengage the clutch plates.
Clamp load is the force that presses the clutch plates together to transmit power from the engine to the transmission.
Release load is the force required to disengage the clutch plates, allowing for gear changes or stopping the vehicle.
The clamp load must be greater than the release l...
The gear box in a vehicle is responsible for transmitting power from the engine to the wheels at different speeds.
The gear box allows the driver to change gears to match the speed and power requirements of the vehicle.
Different gears provide different torque and speed ratios, allowing the vehicle to accelerate, climb hills, or maintain speed efficiently.
Manual gear boxes require the driver to manually shift gears, whil...
Main steering geometry parameters include caster, camber, toe, and steering axis inclination.
Caster: The angle of the steering axis when viewed from the side of the vehicle.
Camber: The angle of the wheels when viewed from the front of the vehicle.
Toe: The angle of the wheels when viewed from above the vehicle.
Steering Axis Inclination: The angle between the steering axis and vertical axis of the vehicle.
Preload in bearings is the internal load applied to a bearing before it is put into service to reduce play and increase rigidity.
Preload is required to eliminate internal clearance and increase rigidity in bearings.
It is commonly used in high precision applications where minimal play is essential.
Types of bearings that may require preload adjustment include angular contact ball bearings and tapered roller bearings.
An easy blend of technical and general knowledge.
I applied via Naukri.com and was interviewed in Sep 2023. There was 1 interview round.
ATS system is a type of transmission system in vehicles, while gear and engine type refer to specific components of a vehicle.
ATS system stands for Automatic Transmission System, which allows for automatic shifting of gears in a vehicle.
Gear type refers to the specific type of gear system in a vehicle, such as manual or automatic transmission.
Engine type refers to the specific type of engine in a vehicle, such as gasol...

Brakes are required in vehicles to slow down or stop the vehicle when necessary.
Brakes help to prevent accidents by allowing the driver to slow down or stop the vehicle when necessary
They also help to maintain control of the vehicle while driving
Different types of brakes include disc brakes, drum brakes, and anti-lock brakes
Regular maintenance of brakes is important to ensure they are functioning properly
Ackerman angle is the angle formed between the steering axis and a line drawn through the center of the wheel.
It is used in the design of steering systems for vehicles.
It helps to determine the turning radius of a vehicle.
The angle varies depending on the type of vehicle and its intended use.
A larger Ackerman angle is used for vehicles that require tighter turning radius, such as go-karts.
A smaller Ackerman angle is us...

Stress-strain curve shows the relationship between stress and strain in a material. It's significant in designing structures.
The curve helps in determining the material's strength, stiffness, and ductility.
It also helps in selecting the appropriate material for a specific application.
The curve can be used to predict the behavior of a material under different loading conditions.
The area under the curve represents the en...
