QFI™ for Motorcycles
Motorcycles and Mopeds
- Capacity from 50cc-250cc
- Integrated solution – throttle body engine management system with ECU, injectors, sensors
- Euro III emissions capable with optimized performance and driveability
- Lightweight, compact, simple to engineer and install with all parts ‘on engine’
- Minimal electrical power consumption ( typical <5 Watts for controller and injector at full speed/load, less at idle)
- Optional idle air control valve
- Truly affordable – low cost through component elimination and integration
Motorcycles and mopeds of all capacities are now being affected by emissions standards. In Europe, most motorcycles now feature electronic fuel injection and engine management, whilst the comparable emissions standards are scheduled for introduction into most international markets within the next few years.
Mopeds with engines less than 50cc will also be affected within a similar period.
Carburettor solutions will be troublesome or impossible to adapt to the legislation, with compromises on performance. Automotive style fuel injection has been successfully applied, but there is a significant cost increase compared to the original carburetor solution which will seriously affect the total vehicle cost, particularly in the Asian markets such as China and India.
Scion-Sprays’ QFI
TM System engine management solution addresses this conflict. Pulse Count Injection (PCI) technology means that the Scion-Sprays injector integrates the functions of fuel pumping, fuel metering and fuel delivery into a compact injector, eliminating the need for a high pressure fuel pump and regulator. This component elimination approach is combined with integration of the system into a throttle body engine management unit comprising throttle body, ECU, sensors and injectors.
Elimination and integration reduces the purchasing cost for engine OEMs. Further benefits are a reduction in other engine / vehicle modifications, reduced weight and space, simplified wiring and a shorter engineering program.
