QFI™ for Utility Engines
New Utility Engine Developments in 2010
Throughout 2009 Scion-Sprays has concentrated on developing motorcycle engine management systems which saw in changes to hardware and software resulting in improved functionality and manufacturability.
In response to upcoming emissions legislation, as well as a shift in consumer demand, Scion-Sprays now feels impelled to build these improvements into its utility engine products.
According to market demand, the technology will remain scaleable from large V-twins down to smaller capacity engines, and configurable with various options such as open or closed loop control and electronic or mechanical throttles.
Manufacturing will take place alongside existing motorcycle products to enable fast and cost effective mass production.
Customers can look forward to exciting new developments throughout 2010.
Utility Applications
- Single and Twin Cylinder
- 4-Stroke engines up to 25 horsepower, ( 50 horsepower as a further development )
- Integrated solution – throttle body engine management system with ECU, injectors, sensors
- Current and future emissions legislation compliance, including evaporative emissions
- 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)
- Truly affordable – low cost through component elimination and integration
- Added value for engine & application manufacturers
Emissions legislation, both exhaust and evaporative, will present increasing issues for small engine designers in future years.
Global competition threatens the competitiveness of manufacturers of traditional engine types.
Modern consumers are used to the advantages that electronic engine management has brought to their automobiles.
The price sensitive utility engines market needs a truly affordable engine management system. To give engine makers a more advanced and competitive product. To give consumers a better experience. To safeguard the future for us and our children.
Carburettor solutions will become troublesome or impossible to adapt to future 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 has so far restricted the adoption to a tiny market niche.
Scion-Sprays’ 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 / application modifications, reduced weight and space, simplified wiring and a shorter engineering program.
