Turbocharged Spark Ignition Two Stroke Engine 942529

This paper will describe an experimental investigation into the performance of a turbocharged spark ignition two-stroke engine. A turbocharging system that incorporates electronic fuel injection, a water to air intercooler, and an expansion chamber exhaust system, has been designed and tested on a 500 cm3, four cylinder, crankcase scavenged spark ignition engine. The engine system has been developed to power a Land Speed vehicle where high specific power output is of utmost importance. Results from dynamometer testing will be presented along with racing results of an open wheeled Lakester class car at the Bonneville Salt Flats.
