Effects of Back Pressure

Effects of Back Pressure Points : effects of back pressure, problems related to exhaust system, problems in internal combustion engines, ic, engine, auto diesel Exhaust back pressure is the amount of pressure developed in the exhaust system when engine is running. High hack pressure reduces engine power. A well designed exhaust system should have low back pressure. The restriction of the exhaust pipes, and muffler contribute to exhaust back pressure. Larger pipes and free-flowing muffler, for example, would reduce hack pressure. Back pressure is produced due to backfiring. Back-firing is caused by the air- fuel mixture igniting in the intake manifold or exhaust system. A loud Bang or Pop sound can be heard when the mixture ignites and burn. Backfiring can be caused by incorrect ignition timing, crossed spark plug wires, cracked distributor cap, or other faults.
