Q1. What is engine working
Ans. 
Engine working refers to the process of converting fuel into mechanical energy to power a vehicle or machine.
• Fuel is ignited in the combustion chamber, creating high-pressure gases that push the pistons down.

• The pistons are connected to the crankshaft, which converts the up-and-down motion into rotational motion.

• The rotational motion is transferred to the transmission, which then powers the wheels or other machinery.

Q2. What is thewirking pronciple of 4 stroje diesel engine
Ans. 
A 4-stroke diesel engine works on the principle of internal combustion, where fuel is ignited by compressed air.
• Intake stroke: air is drawn into the cylinder

• Compression stroke: air is compressed, raising its temperature

• Power stroke: fuel is injected and ignited, causing a rapid expansion of gases and pushing the piston down

• Exhaust stroke: the piston pushes the exhaust gases out of the cylinder

• Diesel engines are more fu...read more
