Abstract
Behavior of particle emission from small non-road engines is still unknown which may have some unavoidable health risk. Investigation of particle emission from small non-road engine has made the main objective in this study. For this purpose a particle counting system has been developed according to the PMP protocol. The investigation was limited to only number counting of solid and volatile particle emission from a small diesel powered electric generator set. Especially the relative emission of solid and volatile particles for different load conditions has been investigated. Measurement was attempted by controlling the dilution air temperature and temperature of an evaporation unit installed inside the particle counting system. It was found that the small diesel engine used in the generator set emits huge number of volatile particles depending on operating condition. Solid particle emission increases and volatile particle emission decreases from the generator engine with increases in operating load.
