Reduction of accidents on public roads by increasing informativeness of drivers

E. S. Voevodin, A. S. Kashura, E. V. Fomin, K.V. Pulyanova, A. M. Askhabov, N.V. Golub
The article reveals the cause of road accidents in the passing direction on the federal roads of the Krasnoyarsk Territory. Analysis of the composition of the traffic flow showed that 50% of cars in the Russian Federation are not equipped with the ABS system. Studies of the magnitude of the braking distance...

Leak detection method for electrohydraulic injectors of diesel engines in operation

Igor V. Yakimov, Elena V. Bondarenko, Sergey N. Krivtsov, Tatyana I. Krivtsova
Modern automobiles equipped with an accumulator fuel-delivery system can fulfill the most demanding operational and ecological requirements. However, when fueldelivery components (predominantly, electrohydraulic injectors) break down, it is difficult to analyze their faults. Therefore, studies aimed...

Decrease of soil adhesion to working bodies of earth-moving machines

S.A. Zenkov, N.A. Balahonov, O.P. Kirichenko
When the moist soil is excavated, the soil sticking and freezing to the working units of the earth-moving machines take place. It is the phenomenon that considerably reduces the plant`s efficiency. There are four main groups of methods intended for eliminating adhesion of soil to the surface of the working...

Study Of Modified Wood As A Bearing Material For Machine-Building

Vladimir Shamaev, Ilya Medvedev, Dmitry Parinov
Modified wood is used in the form of sliding bearings in friction units of various machines and mechanisms, mainly operating under severe operating conditions (combines, rock loading machines, belt conveyors). Wide use of such bearings is constrained by low thermal conductivity of wood. Technology and...
