Before engine assembly, it is important to prepare all necessary components and tools.

• Ensure all engine components are clean and free of debris

• Check all parts for damage or wear and replace if necessary

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.

• Th...read more

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

There are several types of engines, including internal combustion, electric, hybrid, and rotary engines.
