“…It describes how much air can be aspired into the chamber in comparison with the volume of the combustion chamber. It is a nonlinear parameter and is a function of the engine speed and load (η v (rev, load)) [3]. The goal of this section is to describe the estimation routine of this factor.…”

“…2). The mutual dependance between power, con- sumption and AFR has made AFR controllers more and more important, as they balance acceptable fuel economy with satisfactory power output, while minimizing the environmental impact [2,3]. Because of the highly nonlinear dynamics of internal combustion engines, standard electronic control units (ECUs) cannot always produce the desired accurate control performance of the AFR.…”

In-Cylinder Mass Flow Estimation and Manifold Pressure Dynamics for State Prediction in Si Engines

et al. 2014

Abstract. The aim of this paper is to present a simple model of the intake manifold dynamics of a spark ignition (SI) engine and its possible application for estimation and control purposes. We focus on pressure dynamics, which may be regarded as the foundation for estimating future states and for designing model predictive control strategies suitable for maintaining the desired air fuel ratio (AFR). The flow rate measured at the inlet of the intake manifold and the in-cylinder flow estimation are considered as parts of the proposed model. In-cylinder flow estimation is crucial for engine control, where an accurate amount of aspired air forms the basis for computing the manipulated variables. The solutions presented here are based on the mean value engine model (MVEM) approach, using the speed-density method. The proposed in-cylinder flow estimation method is compared to measured values in an experimental setting, while one-step-ahead prediction is illustrated using simulation results.

The internal combustion engine needs to be assessed in terms of thermal loads that come from different sources. Thermal analysis is important in both the design and the evaluation of the conditions of the engine. Interesting good results are obtained by association studies using non-invasive methods such as Infrared and mathematical modelling based on the boundary conditions identified in the experiment. The paper presents a methodology for measuring the surface temperature fields outside of the engine and the mathematical evaluation. The collected material will in future give opportunity to study dynamic thermal states based on the technique of reverse engineering.
