Response surface plots of the BSFC and NOx emission as a function of the injection timing and exhaust gas recirculation (EGR) rate were obtained using a design of experiment method.
The measurement of these oxidized and nitrated substances in diesel exhaust complicates their use as potential biomarkers, since their levels will vary as a function of the oxidizing capacity of the ambient air as well as their residence time in the atmosphere.
In this approach, two conserved scalars are introduced, the mixture fraction Z and the initial exhaust gas fraction J, to determine uniquely the state of the reactive system as a function of the two conserved scalars and time.
In the following, we study the exhausted storage space as a function of L, the sequence length, and N, the number of sequences.
The variation of NO x percentage in the exhaust gas as a function of torque measured is shown in Figure 6.
Each correlation relates the enthalpy wheel sensible and latent effectiveness as a function of six parameters; incoming outdoor air and exhaust air temperature and relative humidity, face velocity, and air flow ratio.
Reactivity as a function of aging was measured in simulated diesel engine exhaust.
It is found that as produced power and heat rate vary as a function of inlet temperature, pressure and inlet duct and exhaust duct pressure drop, vendors supply correction curves to convert ISO conditions to site conditions.
The NOx reduction (DeNOx) activity of the catalyst series was measured as a function of temperature in a flow reactor system fed with a simulated diesel engine exhaust.
These so-called land use regression models have been used to estimate diesel exhaust exposures as a function of wind direction, elevation, and distance from a roadway, truck density, and other geographic- or traffic-related variables (Ryan et al., 2008).
