Development of IAFEM (integrated air fuel electrical modules)

摘要

Nowadays, there are two conflicting requests placed on an engine. One is request for a compact engine to expand the possibility of car design and improve interior comfort and crash safety. The other one is for such technologies as increasing the volume of an air cleaner to reduce intake noise and increasing the length of an intake manifold port to enhance engine output, which can enhance vehicle marketability. Also, a significant cost reduction cannot be achieved by usual C/R activities in component level, therefore a completely new idea is needed. IAFEM (Integrated Air Fuel Electrical Modules), a high-integrated intake module, has been developed to respond to these requests at a time and employed for MZR 1.3/1.5 engines which are mounted on new Demio. This paper describes the technological features of IAFEM.
