A Fuel Injection System for Light Economy Cars 830421

PIPER "PIJET" is a low cost microprocessor controlled fuelling system that can be readily integrated into a total engine management package for single or multi-cylinder engines to 150 BHP (112 KW).
The system introduces fuel at the intake port of individual cylinders via air bled nozzles of unique design that assure good distribution by a process of "natural selection" from a single solenoid injector controlled low pressure fuel supply. The nozzles may be represented as jets of a multi-jet carburettor and are designed to give a high degree of fuel atomisation at small throttle openings.
Although the system is designed to run under microprocessor control any failure of that control will result in a "fail-safe" emergency running mode.
As with any downstream port fuelling system full advantage may be taken of the power and economy advantages of ram-tuned induction together with the extensive use of plastics for system components.
