Embodiment Construction

[0016] according to figure 1 As shown, here is an implementation of a diesel engine electronic control teaching simulation system, including an electronic control unit, a water temperature sensor, an intake pressure temperature sensor, a magnetoelectric sensor, a Hall sensor, a fuel injector, a fuel quantity metering unit, a relay, Tablet PC, teaching software, fault simulation data package.

[0017] The water temperature sensor is a real car used, not connected to the ECU, only for observation and demonstration.

[0018] The air intake pressure and temperature sensor is a real vehicle, not connected to the ECU, and is only for demonstration and teaching.

[0019] The magnetoelectric and Hall sensors are real objects and are used to assist teachers in explaining the working principles of these two sensors.

[0020] The fuel injector, oil quantity metering unit, and relay are real objects, and are connected to ECU, which can be used to simulate actuator failure.

[0021] The...

Abstract

The invention discloses a diesel engine electric control teaching simulation system and method and belongs to the field of diesel engine teaching. The system achieves the functions of helping teachersto explain ECU control logic of diesel engines and the working modes of sensors and executors, simulating and removing common faults of various diesel engines and providing convenience for students to conduct various fault removal experiments to accumulate maintenance experience. The diesel engine electric control teaching simulation system is characterized in that a road spectrum file and a fault simulation road spectrum file during running of a real car can be replayed, and the effect of simulating the running condition of the whole car within a fixed time period is achieved. Massage data emitted by an ECU can be monitored in real time to enable users to understand the ECU state. According to the innovation of the diesel engine electric control teaching simulation system and method, a teaching mode for combining real equipment with a virtual engine is adopted, and a method for using the virtual engine for replaying the fault simulation road spectrum file is adopted for fault diagnosis and teaching.

Description

technical field [0001] The invention relates to a diesel engine electric control teaching simulation system and a simulation method, belonging to the field of diesel engine teaching. Background technique [0002] Traditional electronically controlled diesel engine teaching is mainly divided into two aspects: theory and practice. The theory is to enable students to master relevant professional knowledge and cultivate professional quality, and the most important thing is to demonstrate and practice to students. Today's colleges and universities and vocational colleges have achieved great results in the construction of electronically controlled diesel engine teaching platforms, but they lack practical teaching and demonstration methods. The existing teaching methods are either high in cost, inconvenient in demonstration, or not intuitive. Not very practical. [0003] For the automobile maintenance industry, especially for automobile engine fault detection, substitution detecti...
