Problems solved by technology

Some units also use real objects as models, but they cannot simulate the working stroke of the engine. Individual gasoline engines can use the ignition of spark plugs to demonstrate the ignition timing, but it is not intuitive. At the same time, spark plug ignition is high-voltage electricity, and there are certain safety hazards
Moreover, for a diesel engine without an ignition system, it is impossible to demonstrate the working stroke of the engine

Abstract

The invention discloses an engine demonstration bench comprising an engine, a control system and a demonstration system. The engine comprises cylinder bodies and other engine components. The demonstration system comprises observation holes which are arranged on an engine oil filter, the cylinder bodies, a high pressure pump, a cylinder cover, a power generator, a flywheel shell and a gear room cover, and LED indicating lamps and LED lamp strips. The observation hole of each cylinder of the engine is internally provided with four colors of LED indicating lamps. The LED lamp strips are arranged on an external fuel oil pipeline. The control system comprises a control panel and a control module and can control the engine and the demonstration system to perform demonstration of continuous operation, separate stroke operation and inching operation. The real engine acts as the prototype so as to be closer to the actual situation, and thus students' interest of learning can be enhanced and the teaching effect can be enhanced.

Description

technical field [0001] The invention belongs to the field of teaching aids, in particular to an engine demonstration platform which is convenient for teachers to explain and students to understand the internal structure and working principle of the engine. Background technique [0002] At present, when teachers explain the internal structure and working principle of the engine, they usually use slides, photos, videos and some real objects or models to explain, but the teaching is independent and there is a big gap with the real objects. When faced with the complex engine structure, it is difficult to have a comprehensive understanding of it as a whole, resulting in a lack of intuitive understanding, especially the working principle of the engine, which lacks a more intuitive teaching method, which in turn affects the teaching effect. [0003] At present, the plastic models produced by some enterprises still have a relatively large gap with the real thing, and can only expres...
