DEVELOPMENT OF PROMISING SYNTHESIS - TECHNOLOGY AVENIR GAZ CONVERTING DIESELS TO GAS ENGINES WITH SPECIAL IGNITION

The object of research is the multifunctional synthesis technology Avenir Gaz (of various levels of complexity), intended for converting transport diesel engines into spark-ignited gas internal combustion engines (ICE) for operation on liquefied petroleum gas (LPG).

Investigated problem: the creation of an affordable synthesis technology in terms of complexity and price, which allows converting operating diesel engines into gas internal combustion engines operating on cheaper and environmentally friendly gas fuel - LPG.

Main scientific results: Avenir Gaz synthesis technology (two levels of complexity, qualified as levels "A" and "B") for converting diesel engines into gas internal combustion engines is developed and created. It is shown that the conversion of diesel engines according to the Avenir Gaz synthesis technology is carried out on the basis of the developed electronic microprocessor control systems. And the basis of the control systems is the developed and manufactured two electronic microprocessor control units Avenir Gaz 37 (hereinafter – ECU Avenir Gaz 37). ECUs in accordance with the levels of complexity of synthesis technology are qualified as – ECUs Avenir Gaz 37 "A" and Avenir Gaz 37 "B". It is shown that Avenir Gaz synthesis technology of level "A" allows converting diesel engines into gas internal combustion engines with LPG supply through a gas-air mixer into the inlet pipeline. At the same time, the Avenir Gaz 37 "A" ECU, using the signal from the Hall sensor of the distributor, limits the maximum speed of the gas engine, thereby ensuring its safe operation. And the synthesis technology Avenir Gaz 37 of level "B" allows converting diesel engines into gas internal combustion engines providing group or sequential injection of LPG by electromagnetic gas nozzles (injection system of the Common Rail type) into the intake manifold in the area close to the intake valve.

Area of practical use of the research results: converting diesel vehicles, including agricultural machinery (powerful wheeled and tracked tractors, combines, etc.) into spark-ignited gas combustion engines operating on LPG.

An innovative technological product: Avenir Gaz synthesis technology, which allows converting the transport diesel engines in operation into gas internal combustion engines for operation on LPG.

Scope of application of the innovative technological product: naturally aspirated and supercharged diesel engines with the number of cylinders from one to six, in-line and V-shaped, with a uniform alternation of working strokes.
