Q1. Difference between two stroke and four stroke engine?
Ans. 
Two-stroke and four-stroke engines differ in their operation and design.
• Two-stroke engines complete a power cycle in two strokes of the piston, while four-stroke engines complete it in four strokes.

• Two-stroke engines have a simpler design with fewer moving parts, while four-stroke engines are more complex.

• Two-stroke engines have higher power-to-weight ratio but lower fuel efficiency compared to four-stroke engines.

• Four...read more

Q1. What is velocity
Ans. 
Velocity is the rate of change of an object's position with respect to a frame of reference.
• Velocity is a vector quantity, meaning it has both magnitude and direction.

• It is calculated as the change in position divided by the change in time.

• For example, if a car travels 100 miles in 2 hours, its velocity is 50 miles per hour in the east direction.

Q2. What is IC engine
Ans. 
An IC engine, or internal combustion engine, is a type of engine that generates power by burning fuel inside the engine itself.
• IC engines are commonly used in vehicles such as cars, motorcycles, and trucks.

• They work by igniting fuel-air mixture inside a combustion chamber to create controlled explosions.

• The energy from these explosions is converted into mechanical energy to power the vehicle.

• There are different types o...read more

Q3. Name any three stroke
Ans. 
The three strokes are the forward stroke, the backstroke, and the breaststroke in swimming.
• Forward stroke: Also known as freestyle, swimmers use alternating arm movements to propel themselves forward.

• Backstroke: Swimmers float on their back and use alternating arm movements to move through the water.

• Breaststroke: Swimmers use a frog-like kick and simultaneous arm movements to move through the water.

Q4. What is combustion stroke
Ans. 
Combustion stroke is the phase in a four-stroke engine where the air-fuel mixture is ignited and burned to create power.
• Occurs after the compression stroke in a four-stroke engine

• Ignition of the air-fuel mixture by spark plug or compression

• Explosion of the mixture pushes the piston down, creating power

• Exhaust stroke follows combustion stroke to expel the burned gases

Q1. What is Otto cycle?
Ans. 
Otto cycle is a four-stroke combustion cycle used in spark-ignition engines.
• It consists of four processes: intake, compression, power, and exhaust.

• It is used in gasoline engines.

• It is named after Nikolaus Otto, who invented the four-stroke engine.

• It is also known as the constant volume cycle.
