Faults and remedies for less efficiency of I C engine

Faults and remedies for less efficiency of I C engine
by

1 Answer

Answer :

1. The air intake might be clogged, so there is fuel but not enough air – clean/ replace air filter 2. The fuel system might be supplying too much or too little fuel to the mix, meaning that combustion does not occur properly – check fuel system 3. There might be an impurity in the fuel (like water in your tank) that prevents the fuel from burning – clean fuel tank 4. piston rings are worn (allowing the air/fuel mix to leak past the piston during compression) – replace piston rings 5. The intake or exhaust valves are not sealing properly, again allowing a leak during compression – check for leakage 6. If your sparkplug or the wire leading to it is worn out, the spark will be weak – replace it

Seasonal efficiency

Description : Seasonal efficiency

Last Answer : Seasonal efficiency is how well the boiler uses fuel over the entire heating season. It is the ratio of the total seasonal heat output used by the facility to the total seasonal fuel input. The seasonal efficiency depends on the boiler’s steady-state efficiency, standby losses, and cycling losses.
