Abstract
For protecting human health and preserving the clean environment, current regulations stipulate acceptable levels of particulate emissions based on the mass collected on filters obtained by sampling in diluted exhaust. Such regulations will be imposed not only on-road engines but also off-road engines. From the point of view of human health [1], so-called nano-particle (d<50nm) is thought to be nuisance because it could reach deeper lung tissue. So, many researches have been done in this research field [2].
A series of experiments were conducted on an off-road general purpose direct Injection (DI) diesel engine using EEPS (Engine Exhaust Particle Sizer) to make real time particle size distribution measurements possible. The data presented covers whole operating conditions including the operating modes of off-road diesel engine emission test (C1mode). Additionally, PM emissions in transient (NRTC test cycle) engine operation were examined.
Dramatic changes in PM emission are evident in the data from both EEPS and filters according to the variation in engine operating modes, such as speeds and loads. This illustrates that the physical characteristics of PM is highly dependent on the engine operating conditions. The results also show that the considerable variation of PM emitted during NRTC test cycle. These results indicate the physical characteristics of PM are tremendously varied with practical use.
