The engine sensor simulator is an easy-to-understand teaching model that is used to teach students in higher education, technical schools, and universities about the basic concepts of engine sensors and controllers.
The engine sensor simulation board easily guides students through learning procedures, experiments, and troubleshooting exercises. This program teaches the basic concepts of maintaining and repairing the sensors and controllers of modern automobile engines, maintenance procedures and troubleshooting methods. The training simulation board shows all the typical sensors and controllers of the electronic fuel direct injection engine. The simulation board shows normal and faulty engine conditions. Voltage and resistance can be measured using a digital multimeter.
Course software provides a complete learning course for automotive sensors and controllers. Students start from basic concepts to systematic experiments, and finally to comprehensive troubleshooting exercises. What students are taught is a logical, unique method of gradually solving problems.
