Optimizing Consumption of Gas Fuel Using Static Method of Tuning Automobile Gas-Cylinder Equipment

One of the promising areas in the field of vehicle operation is its conversion to gas fuel (natural gas and methane). Shuttle and taxi cars up to 80% are equipped with gas equipment. A number of automobile plants, both passenger and freight, are concentrated on the production of gas vehicles from the conveyor belt. The main advantages of using gas are significant economy, as well as reduced fuel consumption and toxicity. But with all the advantages of statistics, every second car, running on gas, works with fuel overruns. The analysis of observations from the practice of installing gas equipment indicates some averaging of environmental and economic norms. The adjustment and self-learning by the standard methods are carried out only with the movement of the car. At the same time, it is possible to fine-tune the gas-cylinder equipment on a static (stationary) car. The novelty of the proposed tuning technique is to create a wide range of load ranges for a working internal combustion engine. The loading is performed by the method of full and partial shutdown of the working cylinders. The necessary order of disconnection is provided by the diagnostic device—DBD-3. It is established that this method achieves a reduction in 1.1–2 times of fuel consumption and emission of toxic components.
