Pro-Ject air-assisted fuel injection system for two-stoke S.I. engines

摘要

A new original air-assisted, low-pressure pumpless fuel injection system for two-stroke, S.I. engines is presented. The system does not annul the typical simplicity and low production cost of conventional two-stroke, crankcase scavenged, S.I. engines. Indeed the injection air is supplied by the crankcase and the whole design is based on simple and low-cost solutions. With reference to this system, methodologies are also discussed to improve the behavior of combustion at low loads.
