Favorable resolution of conflict «speed - risk» depends on the perfection of a number of components that constitute the process of traffic : vehicles, road conditions, the level of preparation and discipline of the drivers , the quality of traffic control, as well as some design features of cars , the quality of the brake system, from stability of cars and other reasons, which allow to resolve these contradictions by their perfection and periodic monitoring. Studies have shown that by increasing the pumping losses in the cylinder, a substantial depression, disrupted the process of combustion, indicating reduced efficiency and the engine speed drops. In diesel engines, speed controller at this time transporting rail fuel pump upward cycle supply, as if trying to hold the drop in the number of turns and thus simulates the load ( increase fuel consumption to high) diesel. For gasoline engines high vacuum in the cylinders for a few seconds creates a greater flow of fuel from the carburetor. All this requires a greater expenditure in the early additional braking force and leads to increased heat and wear of rubbing surfaces inefficient brakes and tires.
