Abstract
Advanced diesel engine emits reduced unregulated emissions, but there are few reports on transient emission behavior of the unregulated emissions. This report shows that a time-of-flight mass spectrometer combined with ionization by proton transfer reaction has higher time (as short as seconds) and mass resolution, and its higher sensitivity as low as several ppb was evaluated. The mass spectrometer was applied to measurements of emission from diesel engine to verify effects of DPF.
