FIELD: machine building.
SUBSTANCE: invention relates to the testing and technical diagnosis of machines. Method for determining the specific traction fuel consumption in the breakaway mode of car at a maximum thrust force, in which the machine and the traction device with a dynamograph or dynamometer are prepared for testing, is presented. Car is attached to the traction device and measure the maximum force of traction in the breakaway mode of car. In preparation for the engine test, a fuel flow meter is installed and, when measuring the maximum thrust force, the maximum value of the hourly fuel consumption is additionally measured using the specified instrument. After testing, calculate the specific traction fuel consumption at breakaway of car under load using the formula.
EFFECT: increase in the informative value of the diagnostic and testing of the vehicle.
