Internal combustion engine principle sound and light teaching demonstration system

Abstract

The invention discloses an acoustic-optical teaching demonstration system based on the principle of an internal combustion engine. The acoustic-optical teaching demonstration system comprises internal combustion engine structural parts and external transmission, photoelectric and control components, and can not only vividly display the work principle of a gasoline engine, but also display the work principle of a diesel engine through switching by a control system, thereby combining the work principle and characteristics of the gasoline engine and the diesel engine. The acoustic-optical teaching demonstration system has the advantages that through the adoption of the technology of mechanical and electronic integration, the purpose of automatic control of the displaying of the work principles of the gasoline engine and the diesel engine is realized through battery power supply, and the automatic control is symbolized through intuitive forms such as sound and light; the part sharing rate is high; materials are saved; the structure is compact and clear; the degree of automation is high; the electricity source is wide; the carrying is convenient; the main body material mainly adopts wide-source materials such as glass, plastic or other transparent media and wood, so that the similarities and the differences of the main working principles of the gasoline engine and the diesel engine can be displayed clearly.

Description

technical field [0001] The invention relates to the field of internal combustion engine teaching and teaching instruments, in particular to an internal combustion engine principle integration composite acousto-optic teaching demonstration system including a gasoline engine and a diesel engine. Background technique [0002] As a power source for transportation and construction machinery, engines play an important role in national economic production and technological development. With the rapid development of the automobile industry and technology with independent intellectual property rights in my country, the demand for talents in the engine technology industry is also increasing. It is getting bigger and bigger, especially in recent years, the engine technology has made rapid progress. More and more traditional gasoline engines and diesel engines have applied electronic control and other technologies, making the working principle of the engine also complicated. In order to p...

Problems solved by technology

[0003] Generally, traditional internal combustion engines are divided into two types: gasoline engines and diesel engines. Due to the different working principles of these two engines and the complexity of their structures, as well as the precision of the internal structure and the large number of parts and other reasons, it is difficult to make an initial contact with the engine. At the same time, since most of the current engine teaching models show gasoline engines and diesel engines separately, the differences and similarities between the two need to be understood and distinguished by the learners themselves, and the internal parts of the engine are not easy to visualize Therefore, there is an urgent need for a teaching instrument that can not only vividly display the internal structure and working principle of the engine, but also integrate the gasoline engine and the diesel engine so that visitors and learners can intuitively understand the similarities and differences of the two engines. The demand for teaching instruments is increasing, and the cost of teaching instruments, the reusability of materials, and environmental protection should also be considered, so as to meet the needs of engines that can easily demonstrate the similarities and differences in the working principles of gasoline engines and diesel engines, and can save energy and produce environmental benefits. Teaching instruments are becoming more and more important
