The engine operating condition simulator is an easy-to-understand teaching model, which is used to teach students, colleges, technical schools, and universities about the basic concepts of engine operation.
The engine operating condition simulation board easily guides students through learning procedures, experiments and troubleshooting problems. This program teaches the basic concepts of maintenance and repair of modern automobile engines, maintenance procedures and troubleshooting methods. Display on the emulation board
Shown are the main sensors and controllers that can be found in modern computer-controlled cars. By providing parameter measurement, providing constantly changing engine operation and working conditions, independent engine sensors and control devices are
The effects of energy and exhaust emissions can be demonstrated under different operating conditions. Ambient temperature and height adjustment devices are used to display the influence of the environment on the operation and working conditions of the engine.
Course software provides a complete learning course for automotive engine systems. 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.
Description This simulator shows the engine operation, operating conditions and exhaust emission control. The simulation board contains exercises to control input and output with a computer. The influence of independent engine sensors and control devices on engine performance and exhaust emissions can be
It was demonstrated under the same operating conditions. Ambient temperature and height adjustment devices are used to display the influence of the environment on the operation and working conditions of the engine.
The system components training system includes: simulation panel; student experiment manual.
The following components are provided on the simulation board for students to get started easily: inherent multimeter; knock sensor; intake injection management system; throttle body fuel injection; oxygen sensor; idle air control system; throttle position sensor; engine
Coolant meter temperature sensor; sensor; engine tachometer; coolant temperature sensor; exhaust gas recirculation system.
Purpose of study:
1 Understand how the engine works
2 Understand how the basic components of the engine function move
3 Understand the types of faults that occur in the engine
4 For engine systems, use reasonable troubleshooting methods
