Abstract
A well-known problem in achieving an environmental effect from the use of natural gas is the loss of gas fuel during valve overlap, as well as during incomplete combustion at low consumption of the mixture when supplied to the intake manifold. An important condition affecting the amount of lost fuel is the method of supplying the gas-air mixture. It makes sense to imagine a description of a jet of gas fuel in an air flow in the geometry of the intake pipeline, as in the shape of the passage of the axis of the jet in the drifting flow. Knowing the depth of penetration into flow structures and its geometry makes it possible to position the jet in such a way as to avoid the accumulation of gas fuel in the intake manifold of a car engine. When describing the shapes of jet orientation, the empirical coefficient of penetration resistance is of great importance. An attempt was made to find a pattern of changes in the coefficient depending on the initial angle of fuel supply in the smaller direction of the jet advance.
