Problems solved by technology
To carry out the teaching of these contents, schools need to spend a lot of money to purchase expensive equipment such as diesel engines and their fuel systems, test benches, engine benches, and dynamometers.
As a result, due to the high cost, the experimental course of diesel engine electronic control teaching cannot be carried out basically, and students cannot really grasp the characteristics, control principles and tuning methods of diesel engine electronic control technology.

The invention discloses a diesel engine electric control teaching experimental system and a simulation method of the diesel engine electric control teaching experimental system. By means of the diesel engine electric control teaching experimental system and the simulation method of the diesel engine electric control teaching experimental system, units concerned can carry out teaching and studying on the diesel engine electric control technology at low cost, the operational ability of students is improved, and knowledge about the diesel engine electric control technology of the students can be increased. By the adoption of equipment and the method, starting of a real engine and consumption of fuel are not required, so that cost is lowered, and the structure, the principle and the electric control technology of a diesel engine are taught to the students.
Description
technical field [0001] The invention belongs to the technical field of teaching simulation, and in particular relates to a diesel engine electric control teaching experiment system and a simulation method thereof. Background technique [0002] With the development and progress of science and technology, electronic control technology has become the mainstream of automobile engine control technology at home and abroad. Many experts in this field believe that colleges and universities should add the content of diesel engine electronic control teaching. To carry out the teaching of these contents, schools need to spend a lot of money to purchase expensive equipment such as diesel engines and their fuel systems, test benches, engine benches, and dynamometers. As a result, due to the high cost, the experimental course of diesel engine electronic control teaching cannot be carried out basically, and students cannot really grasp the characteristics, control principles and tuning met...
