BACKFIRING IS CAUSED BY FAULTY IGNITION. -Almost always the cause of back-firino-is faulty ignition. Ihe gas charge is sucked in on the stroke of the piston and compressed. But at the time when ignition should take place no spnrk, or an ineffective spark, is made, and the gas remains inert. On the down stroke, which should be the power stroke, this charge is expanded, and in the subsequent upstroke it is exhausted in its still unexploded form into the exhaust manifold or silencer. The undischarged explosive gas can only enter the exhaust pipe, via the exhaust valve. When it gets there it is exploded by the subsequent red-hot exhaust discharge.
