Q1. What is the difference between a diesel engine and a petrol engine?
Ans. 
Diesel engines use compression ignition while petrol engines use spark ignition.
• Diesel engines use compression ignition, where the fuel-air mixture is compressed until it spontaneously ignites.

• Petrol engines use spark ignition, where a spark plug ignites the fuel-air mixture.

• Diesel engines are more fuel efficient and have higher torque, while petrol engines have higher power output and smoother operation.

• Diesel engines...read more

Q2. What is a four-stroke engine?
Ans. 
A four-stroke engine is an internal combustion engine that completes four separate strokes (intake, compression, power, exhaust) in two crankshaft revolutions.
• Intake stroke: Fuel and air are drawn into the combustion chamber.

• Compression stroke: The fuel-air mixture is compressed by the piston.

• Power stroke: The spark plug ignites the mixture, causing an explosion that drives the piston down.

• Exhaust stroke: The piston pu...read more

Q4. What is ABS system
Ans. 
ABS system stands for Anti-lock Braking System, a safety feature in vehicles to prevent wheels from locking up during braking.
• ABS system helps maintain steering control during emergency braking

• It prevents skidding and allows the driver to maintain control of the vehicle

• ABS system works by modulating brake pressure to individual wheels

• Commonly found in modern vehicles for enhanced safety

• Example: When braking hard on a s...read more

Q5. What is carborator
Ans. 
A carburetor is a device in an internal combustion engine that mixes air with a fine spray of liquid fuel.
• Carburetors are used in older vehicles to control the air-fuel mixture for combustion

• They have been largely replaced by fuel injection systems in modern vehicles

• Carburetors have components such as throttle, choke, and jets to regulate fuel flow

• Examples of vehicles with carburetors include classic cars and motorcycl

Q1. What are you know about Hook's law
Ans. 
Hook's law states that the force needed to extend or compress a spring by a certain distance is directly proportional to that distance.
• Describes the relationship between force and extension/compression of a spring

• Mathematically represented as F = kx, where F is the force, k is the spring constant, and x is the displacement

• Used in various fields such as engineering, physics, and material science

Q2. Principal of auto cycle engine
Ans. 
The principal of an auto cycle engine is based on the four-stroke cycle of intake, compression, power, and exhaust.
• Auto cycle engines operate on the principle of converting chemical energy from fuel into mechanical energy.

• The four-stroke cycle includes intake of air and fuel, compression of the mixture, ignition and combustion, and exhaust of the waste gases.

• This cycle repeats continuously to generate power and drive t...read more
