Abstract
Pressure wave oscillations occurring in both the intake and exhaust manifolds can potentially be applied to exhaust gas recirculation (EGR) and selective catalytic reduction (SCR), to increase their distribution efficiency and further reduce nitric oxide (NOx) emissions. The work consists of an in depth study on pressure wave propagation in diesel exhaust manifolds for various operating conditions, such as: RPM, IMEP, EGR, Post-injection, backpressure, runner length, runner diameter, and position sweeps. The effect of pressure wave propagation in diesel manifolds, by varying such engine operating parameters, and geometric exhaust configurations, have been demonstrated empirically, and by simulation. By understanding the characteristic behavior of the pressure waves, such as frequency, amplitude, and phasing, under different engine operating conditions, better EGR and SCR distribution strategies may be found. This may be done by implementing different manifold configurations and injection strategies, to the EGR and SCR systems, respectively.
