Design and Applied Research of Corolla 1.6 AT Electronic Controlled Engine Experiment Bench

Abstract

Experiment bench is based on Toyota Corolla 1.6 AT electronic controlled engine by use of the principle of virtuality and simulation, without mechanical system, but electrical control units are reserved. The bench has simple structure and low cost, and it is safe, environmental protection and economic when using; temperature sensor signals are simulated by variable resistance, and the working process of some actuators is shown using light bulbs, so that the whole bench is easy to operate, and the working process is visual and direct; the bench panel is equipped with measuring terminals to facilitate testing and practical teaching. The bench can also be independently developed, designed and produced by students under the guidance of teachers, which is beneficial to arousing the students' innovation consciousness. At present, modern has become a high-tech composite integrated with machine, electricity and liquid, of which the engine electronic control has been mature day by day, and its feature as the carrier of high and new is more and more obvious(1). In order to strengthen practical teaching of speciality in higher vocational colleges, and raise students' professional skills, there is an urgent need to develop some teaching equipment suitable for the development and conforming to the concept of modern vocational education, with low cost, no pollution, easy to use and safety. Nowadays, in terms of speciality in vocational colleges, the automobile engine electronic control technology is deemed as a professional core course for teaching. To assist the theoretical and practical teaching of this course, it is necessary to develop an electronic controlled engine experiment bench, so that students strengthen the awareness of electronic controlled engine, and master the detection and diagnosis ideas of common fault about electronic-controlled engine through repeated simulation experiment; teachers can improve their theoretical and practical level by developing and fabricating experimental equipment (2).
