Abstract
Partially Premixed Combustion (PPC) is an advanced combustion concept resulting in high efficiencies and low emission levels by the use of high levels of EGR and pilot injections. The main limitation of PPC to use in practice lies in the high pressure rise rate, which causes issues on engine noise and durability. In addition, soot emissions face with the overshoot problem during the transient operations. This paper proposes an approach to simultaneously control soot emissions and maximum pressure rise rate. The controller presented in this paper consists of measured cylinder pressure, a control-oriented soot model, a set of feedforward PI controllers for combustion phasing and engine load, and a set of gain-scheduled PI controllers for...

Partially Premixed Combustion (PPC) is an advanced combustion concept resulting in high efficiencies and low emission levels by the use of high levels of EGR and pilot injections. The main limitation of PPC to use in practice lies in the high pressure rise rate, which causes issues on engine noise and durability. In addition, soot emissions face with the overshoot problem during the transient operations. This paper proposes an approach to simultaneously control soot emissions and maximum pressure rise rate. The controller presented in this paper consists of measured cylinder pressure, a control-oriented soot model, a set of feedforward PI controllers for combustion phasing and engine load, and a set of gain-scheduled PI controllers for soot and pressure rise rate. The controller was implemented on a Scania D13 heavy-duty engine, and evaluated during a load transient operation. By manipulating the pilot injection strategy, soot emissions were able to meet the Euro 6 heavy-duty emission standard without an aftertreatment system, and pressure rise rate was limited to a relatively low level without too much compromising the engine efficiency.
