Q5. Fuel injectors in diesel engine
Ans. 
Fuel injectors in diesel engines are responsible for delivering fuel into the combustion chamber at high pressure.
• Fuel injectors atomize the fuel into a fine mist for better combustion efficiency.

• They are controlled by the engine's electronic control unit (ECU) to precisely regulate fuel delivery.

• Common issues with fuel injectors include clogging, leaking, or failing to open/close properly.

• Regular maintenance and clean...read more

Q2. 2. What is the working principle of diesel cycle?
Ans. 
Diesel cycle is a thermodynamic cycle used in diesel engines to convert heat into work.
• Air is compressed in the cylinder, causing its temperature to rise.

• Fuel is injected into the cylinder, igniting due to the high temperature.

• The expanding gases push the piston, converting heat into mechanical energy.

• Exhaust gases are expelled from the cylinder.

• Diesel cycle is more efficient than Otto cycle used in gasoline engines.
