Car backfire definition

In simple terms, car backfire is when there is an explosion of fuel in the exhaust or manifold of an internal combustion engine. These issues happen as a result of:

  • Faulty plug wires
  • incorrect timing
  • weak fuel pressure
  • computer faults
  • Leak in the vacuum hose

 The engine is a complicated piece of equipment for people that are not very familiar with it. There are certain requirements that must be met in order for the engine to run properly. This is why timing plays such an integral role in preventing car backfire. Spark plugs must produce a spark at the right time so the engine can run properly, if this does not happen, the air and fuel mixture will not be ignited properly. This problem can also be due in part to a leak in the air injection system or if there is a sudden drop in the fuel pressure. Fortunately, these problems can be fixed, but before you reach the stage of fixing the problem there are things that can be done to prevent car backfire.
