Abstract
A newly developed turbocharging system, named MIXPC, is proposed and the performance of the proposed system applied to diesel engines is evaluated. The aim of this proposed system is to reduce the scavenging interference between cylinders, and to lower the pumping loss in cylinders and the brake specific fuel consumption. In addition, exhaust manifolds of simplified design can be constructed with small dimensions, low weight and a single turbine entry. A simulation code based on a second-order FVM+TVD (finite volume method + total variation diminishing) is developed and used to simulate engines with MIXPC. By simulating a 16V280ZJG diesel engine using the MPC turbocharging system and MIXPC, it is found that not only the average scavenging coefficient of MIXPC is larger than that of MPC, but also cylinders of MIXPC have more homogeneous scavenging coefficients than that of MPC, and the pumping loss and BSFC of MIXPC are lower than those of MPC. To validate the prediction results, experiments of a 16V280ZJG diesel engine equipped with MIXPC have been successfully finished. Experiment results show that the MIXPC turbocharging system reduces the exhaust gas temperature before turbine and BSFC at part load, and the exhaust gas temperatures at each cylinder outlet at high load are more uniform. The resulting lower thermal load suggests that the diesel engine equipped with MIXPC has the potential to increase its power.
