Abstract
BACKGROUND: Leading manufacturers of engines for trucks are constantly competing and trying to create engines with the best consumer characteristics, which at the same time meet modern environmental standards. One of the most important characteristics for long-haul tractors is fuel efficiency. As a way to improve this parameter, it was chosen to reduce the loss of mechanical energy to drive the oil pump.
AIMS: To determine the current level of mechanical losses in the drive of the oil pump of the KAMAZ 6ChN13/15 engine, to form a set of solutions to reduce losses.
METHODS: The current pattern of mechanical losses distribution for the 6ChN13/15 engine was obtained by engine motoring at the engine bench with sequential removal of engine components. A comparative diagram of the overpressure at the outlet of the uncontrolled and controlled pumps was obtained empirically during tests at the engine bench. The evaluation of the positive effect from the use of a controlled oil pump was determined analytically.
RESULTS: As a result, by using a controlled oil pump, it became possible to reduce the excess pressure at the outlet of the pump at nominal rotational speed by 25%, which theoretically should reduce the relative mechanical losses of the engine by 3%.
CONCLUSIONS: The practical value of the study lies in determining effective ways to reduce mechanical energy losses and improve the consumer qualities of modern diesel engines.
