This paper describes two advanced electronic fuel injection systems for small vehicles which have recently become commercially available. Both systems have been designed and developed by the author's organisation.One of the two systems (‘aSDI’) has been designed and developed for 2-stroke engines and the other (‘SePI’) for 4-stroke engines. Both systems are intended for application on small vehicles fitted with small 1 – 2 cylinder gasoline engines of displacement 50 – 250 cm3 per cylinder. Typical examples of such small vehicles are: ATV's (All Terrain Vehicles), auto-rickshaws, motorcycles, motorscooters and mopeds1.Fuel consumption and emissions results from both systems are presented, and in both cases it is shown that engine-out exhaust emissions meet current and future limits in Europe, India and Taiwan, without the need for exhaust after-treatment. It is also shown that both systems offer significant fuel savings relative to otherwise-equivalent, carburetted baseline vehicles.Other important benefits of these systems which are discussed in this paper are improved cold start and improved driveability.The paper also includes a short overview of the performance and cost implications of both systems relative to alternative emissions control methods.
