Where Fuel Meets Air

Location: Forum Stage 7

Presenter: Mike Busch

Spark-ignition reciprocating engines require that fuel be mixed with air in the proper proportion to support efficient combustion, a process known as "fuel metering." Engine expert Mike Busch discusses various methods of accomplishing this -- float carburetors, pressure carburetors, throttle-body injection, intake port injection -- and offers detailed explanations of how each of these metering mechanisms work.
