It is required to reduce both the friction and lubricant oil consumption (LOC) in order to reduce CO2 in internal combustion engines. In addition, as the requirement to reduce particulate number (PN) may be realized by reducing LOC, the relationship between LOC and PN should be examined. Elucidation of the mechanism of LOC belongs to a basic and applied field and a common subject, however, only the LOC is measured by the weight method in steady conditions and the mechanism is not clarified so far. Thereby, the relationship between LOC and PN was measured in a wide operation area including transient conditions using a production engine in this study.
