Programming of the Engine Control Unit by the C Language

An engine control system turns complicatedly year by year to satisfy the requirements of the low pollution, low fuel consumption and high performance.

Though assembly language has been used for programming of the Engine Control Unit(ECU) so far, we adopted the C language to improve the productivity of the software. Therefore it becomes possible to develop the high reliability program in a short period.

This paper introduces about the overview of ECU which employs high speed 16- bit microcomputer programmed by the C language.
