Abstract
A low cost multipoint fuel injection system which utilises no-moving-part fluidic devices as fuel injectors for gasoline engines is presented in this paper. This unique fluidic injector unit consists of four monostable fluidic devices, four air-fuel mixing nozzles and a prototype solenoid pulser interface for switching the fluidic stages.
The current Electronic Fuel Injection (EFI) systems are reviewed and features of the fluidic injection system are illustrated in this paper. Preliminary investigation on the operating characteristics of the prototype unit was carried out both on a laboratory rig and on an engine test bench. The improvement in air/fuel mixture preparation by the fluidic fuel injection system compared with a baseline carburettor has been demonstrated.
