Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner emissions, all from a more precise way of delivering fuel. On paper, the ...

Electronic fuel injection is older than you think, the earliest example being the failed Bendix Electrojector system from 1957. Bosch bought the rights to the Eletrojector system and developed it into ...

In the past, race-type constant flow fuel injection (Fl) systems have met with little success on the street. Usually designed only for high-speed idle and wide-open throttle (WOT) operation, such ...
