Abstract: The effects of basic engine operating parameters on particle emissions from a hybrid city bus were examined under urban driving conditions involving both constant speed and frequent acceleration. To perform the examinations, real-time data for the parameters and solid Particle Number (PN) emissions were synchronously collected. The driving conditions were specifically chosen because, depending on the driving conditions, PN emissions from a city bus may change by an order of magnitude. A PN measurement system highly sensitive to engine transients and background emissions was specifically chosen, because the particle emission levels typically found in modern diesel engines are relatively low.
