Abstract

The invention discloses a modular electronic-controlled engine model. The modular electronic-controlled engine model comprises a mechanical portion and a control circuit portion. In the mechanical portion, a piston, a connecting rod, a crank, a cylinder, a cylinder cover and a crankcase are assembled into a single-cylinder engine model, and then multiple single-cylinder engine models are assembled into a in-line type V-shaped opposite-type multicylinder engine model. The control portion is composed of a single chip microcomputer, a position sensor, LED lamps and a power source. The position sensor is located at the upper dead center of the cylinder, and used as the input single of the single chip microcomputer to control the operation of the LED lamps. The lighting of the yellow LED lamp indicates the ignition working condition. The lighting of the red LED lamp indicates the inlet valve opening condition. The lighting of the greed LED lamp indicates the exhaust valve opening condition. By observing the LEDs and the movement of the piston, the multicylinder engine successful ignition time and the inlet valve and exhaust valve opening and closing time can be obtained. The modular electronic-controlled engine model of the invention can be used in the engine teaching practices in universities to help students to understand the working sequence and valve opening and closing time of different types of engines having different cylinder number.

Description

technical field [0001] The invention relates to a teaching tool, in particular to a modular electric control engine model. Background technique [0002] At present, in the practice of engine teaching in colleges and universities, due to the complex and bulky parts of traditional engine models, it is inconvenient to disassemble and assemble. Moreover, the engine models are all in fixed form and have a single function. The working process of the engine is not intuitive enough, and the teaching effect is not very ideal, which is not conducive to students' understanding of the working process of the engine. Contents of the invention [0003] The purpose of the present invention is to provide a modular electronically controlled engine model to solve the problems in the engine teaching practice that the traditional engine model has complex and heavy parts, inconvenient disassembly and assembly; the working process of the engine is not intuitive enough, and the function of the e...
