A diesel generator works by converting diesel fuel into mechanical energy which is then converted into electrical energy.

• Diesel fuel is injected into the combustion chamber where it ignites and creates high pressure gases that push the piston down, creating mechanical energy.

• The mechanical energy is then converted into electrical energy through the use of an alternator.

• The alternator uses a magnetic field and a conduct...read more

A diesel engine works by compressing air in the cylinder, which heats up and ignites the fuel injected into the cylinder.

• Air is drawn into the cylinder and compressed by the piston

• The compressed air heats up and ignites the fuel injected into the cylinder

• The explosion pushes the piston down, which turns the crankshaft and powers the engine

• Diesel engines are more efficient than gasoline engines because they compress the...read more

A train doesn't need a differential because its wheels are fixed to the same axle and rotate at the same speed.

• Train wheels are fixed to the same axle

• Wheels rotate at the same speed

• Differential is used in vehicles with wheels that rotate at different speeds

• Differential allows for smooth turning

Petrol engines have lower compression ratios compared to diesel engines.

• Petrol engines have lower compression ratios to prevent knocking or detonation.

• Diesel engines have higher compression ratios to ignite the fuel without spark plugs.
