The article presents the results of experimental studies of technological parameters of a pilot sample of aerosol type lubricant. As a lubricant, the industrial I-12A oil was added with the addition of graphite powder to it, which provides the implementation of a two-layered coating of the working surface of the rail. The test piece is a closed type oiling unit, which feeds on compressed air and allows the regulation of air and oil supply to the working nozzle. For drawing of a lubricant on a working surface the coaxial nozzle with the external formation of an aerosol - a mixture of oils and air is used.Studies were conducted in laboratory conditions. At the first stage, the geometric dimensions of the stain of the oil applied to the vertical surface were measured, depending on the distance between the nozzle and the surface. Such data makes it possible to adjust the settings of the injector placement relative to the rail, taking into account the permissible dimension of the approach, which is essential for the introduction of rail pads under operating conditions. Subsequently, depending on the width of the stain of the oil and the thickness of the lubricating layer from the supply of oil and air, were installed. Also, the dependencies of the cutting time of oil and air are set. The obtained data are necessary for determining the oil consumption in the operation of similar rail lubricants in real conditions. In addition, these data allow you to adjust the control system of the rail lubricant by the criterion of the limit time of cutting the oil and minimizing the cost of lubricant.According to the results of laboratory studies, an estimation of the effectiveness of the aerosol type air-lubricant was performed on the criterion of the total consumption of the lubricant for the predicted resource of the rails in the curved sections of the track. It was obtained the dependence of the number of inclusions of the lubricant and the lubricant flow rate on the number of load cycles for the rails for the projected resource. For one load cycle, a single passage of the wheelset of rolling stock along the rail was taken.
