FOUR-STROKE CONSTANT PRESSURE SUPERCHARGED DIESEL ENGINES: EXPERIMENTAL RESEARCH AND OPERATING RESULTS
For the supercharging of four-stroke diesel engines the trend is to replace the pulse system with the constant pressure system. Several publications deal with advantages and disadvantages of the latter solution, but some problems concerning the matching engine-charging system seem not to have been fully clarified. Therefore, a comparative investigation was carried out at the Authors' Company on medium speed engines equipped with the two supercharging systems. The investigation included firstly bench tests on scavenging phase and exhaust valves thermal load, comparing different supercharging systems and exhaust duct configurations. The second part of the investigation, concerning performance stability in the course of time, has been carried out on engines in actual service.
