“…The heat release rate depends also on the physical conditions of the mixture and on other parameters such as the available kinetic energy (see [8] or [9]). Researches have thus been carried out to control combustion timing in order to stabilize the whole combustion process.…”

We propose a model based control strategy to adapt the injection settings according to the air path dynamics on a Diesel HCCI engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the start of combustion. For that purpose, start of injection is adjusted based on a Knock Integral Model and intake manifold conditions. Experimental results are presented, which stress the relevance of the approach.

Soot and smoke emissions numerical evaluation for a direct injection (DI) diesel engine

Abstract.The reduction of Diesel internal combustion engines emissions is one of the major concerns of the engines manufacturers. Despite the fact that the efficiency of the gas post-treatment systems has been significantly improved, decreasing the smoke and the soot from the cylinder inside remains a main research goal. This work is proposing a theoretical study on these pollutants formation for different kinds of direct injection methods. By dividing the in-cylinder injection the heat release characteristic could be modified, leading to different temperature and pressure levels. Using exhaust gas recirculation (EGR) the reduction of the gas temperatures might also be decreased, limiting NOx formation. To evaluate the level of the cylinder gas emissions formation a two-step procedure could be followed. First, by using a numerical calculation system the heat release characteristic can be highlighted concerning a Diesel engine with stratified injection; then, using an experimental relationship applying a large data base, the amount of the gas emissions can be subsequently provided. The authors propose some combinations between injection characteristics and EGR used fractions which could generate successfully results speaking in terms of NOx, soot and smoke formation.

“…Cylinder wall heat losses are modeled using a Woschni approach with three independent temperature variables for the cylinder head, the piston and the liner. The combustion heat release model is based on a conventional 0D Diesel combustion model approaches ( [6], [2]) extended to multi-pulse injection, auto-ignition delay and EGR effect correction in order to get good combustion behavior over the whole range of operating set points, especially in both Highly Premixed Combustion (HPC) and conventional combustion modes. The airpath of the engine is equipped with an air throttle, an EGR valve, a Variable Geometry Turbocharger and a VVA actuator (see Figure 2).…”

In this paper, we propose a strategy to control the incylinder burned gas rate inside the combustion chambers of turbocharged Diesel engines equipped with low pressure EGR loop and VVA actuator. We first design a mean-value model of the in-cylinder composition and validate it on a high frequency reference simulator. Then, we develop the control strategy. It is based on the coordination of existing low-level controllers acting separately on the EGR valve and on the VVA actuator. The objective is to improve transient response, taking into account the responses of the low-level controllers. Supportive simulation results show the relevance of this approach.
