INFLUENCE OF THE HIGH-SPEED MODE OF MOVEMENT OF VEHICLES ON WEAR RESISTANCE OF BEARINGS OF CRANKED SHAFT OF ENGINES ^{[№ 10 ' 2011]}
In article laws of wear resistance of bearings of cranked shaft of engines depending on a high-speed mode of movement of vehicles (on an example of the car VAZ-2107 and bus PAZ-3205) are established. Techniques and results of trial runs of vehicles for reception of high-speed characteristics by new criterion of wear resistance of bearings of cranked shaft by means of an original express technique are resulted. High-speed modes of movement of the vehicles, providing the maximum wear resistance of bearings are defined.

TECHNIQUE FOR ASSESSMENT OF CAR ENGINE SUITABILITY FOR CHANGING EXPLOITATION ENVIRONMENT ^{[№ 4 ' 2009]}
The paper describes stages of development and approbation of the technique to assess suitability of the car engines to changing exploitation environment (starting duty as a case study) with the use of original method of express-analysis of the lubricant in the crankshaft bearings. Practical application of this technique enables to improve the service life of car engines through lovering starting wears.
