METHOD OF MAKING DEVICE FOR VARYING SPEED OF DIESEL ENGINE USED IN MEASURING OPACITY OF EXHAUST GASES OF DIESEL ENGINE Russian patent published in 2024 - IPC G01M15/02 G01M15/10 

FIELD: measuring.

SUBSTANCE: invention relates to measurement of opacity of exhaust gases of diesel engines. Disclosed is a method for manufacturing a device for changing the speed of a diesel engine, used when measuring opacity of exhaust gases of a diesel engine, which comprises making solid base 1 made from a steel sheet with a fabric plate glued to the bottom; programmable microcontroller 2 and servo drive 3 with control of the angle of rotation of its shaft and supply battery 6 are attached to the base. Lever 5 is made on the shaft of servo drive 3 to touch electronic accelerator pedal 4 with the possibility of uniform movement of the electronic accelerator pedal in response to the generated command signals from programmable microcontroller 2. Communication is programmed through Wi-Fi module 7 for transmitting a command signal for the beginning of measuring opacity from a computer over a wireless local area network. Programmable microcontroller 2 is programmed to perform six consecutive cycles of free acceleration of the crankshaft of the diesel engine as per the number of measurement cycles of the smoke content of the exhaust gases of the diesel engine.

EFFECT: increasing the accuracy of determining the amount of opacity in exhaust gases on diesel engines of wheeled vehicles with an electronic accelerator pedal in automatic mode.
