As a result of environmental pressures and end-user demands several companies are working on low cost fuel injection systems specifically for small motorcycles and utility engines. A common approach to this application is to take an existing engine management system derived from automotive or high end motorcycle applications and to re-design it to reduce its complexity and cost for the small engine market. This paper introduces and discusses the latest development and application of a novel engine management system designed from the outset specifically for low cost small engines for motorcycles and utility applications (Pulse Count Injection, PCI [ref 2, 3]). The paper details comparisons of the performance of the PCI system compared to carburettor and conventional EFI systems. Detailed results are shown for; Fuel consumption comparison Engine out emission benefits Fuel flow comparison Cost reduction The paper demonstrates the latest state of development of the PCI system technology.
