“…With nine inputs, there would be 55 terms at most in Equation ( 2), considering the coupling effect of every two combustion parameters. A total of 2000 stable engine running cases were used to determine the fitting coefficients in Equation (2).

“…Among all the control methods for partially premixed combustion, cylinder pressure-based combustion phase control is an essential technology for diesel combustion. According to the measurement of in-cylinder pressure, real-time combustion characteristics can be derived and analyzed [2]. The injection timing was proved to be strongly related to the center of combustion phase (CA50) at an early time [3].…”

With the increase of information processing speed, more and more engine optimization work can be processed automatically. The quick-response closed-loop control method is becoming an urgent demand for the combustion control of modern internal combustion engines. In this paper, artificial neural network (ANN) and polynomial functions are used to predict the emission and engine performance based on seven parameters extracted from the in-cylinder pressure trace information of over 3000 cases. Based on the prediction model, the optimal combustion parameters are found with two different intelligent algorithms, including genetical algorithm and fish swarm algorithm. The results show that combination of quadratic function with genetical algorithm is able to obtain the appropriate combustion control parameters. Both engine emissions and thermal efficiency can be virtually predicted in a much faster way, such that enables a promising way to achieve fast and reliable closed-loop combustion control.

“…The reduction of oxygen concentration caused by air intake delay decreases the nitrogen oxide (NOx) emission. Furthermore, the lack of oxygen leads to an increase of the goal equivalence ratio which causes a poor smoke emission [9][10][11][12][13]. Filipi et al [14] claimed soot emission increases rapidly when the load has a sudden increase from idle state.…”

To reduce the smoke and nitrogen oxide (NOx) emissions; a detailed study concerned with exhaust gas recirculation (EGR) and diesel injection strategy was conducted on a two-stage series turbocharging diesel engine under transient operating condition. One transient process based on the constant speed of 1650 r/min and load increases linearly from 10% to 100% within 5 s was tested in this study. The effect of the EGR valve control strategy on engine transient performance was examined. The results show that better air-fuel mixing quality can be obtained with the optimized the EGR valve open loop control strategy and the smoke opacity peak decreased more than 64%. Under the EGR valve close loop control strategy; the smoke opacity peak was lower than with open loop control strategy; but higher than without EGR. The effect of fuel injection strategy on engine transient performance was examined with the EGR valve close loop control. The results show that sectional-stage rail pressure (SSRP) strategy (increasing injection pressure from a turning point load to 100% load) and optimizing fuel injection timing can improve the engine emission performance. The satisfactory results can be obtained with lower NOx (382 ppm) emissions and the smoke opacity peak (3.8%), when the turning point load is set to 60% with the injection timing delay 6° CA.

“…It is also difficult to use any direct measurement or observation for verifying these instantaneously [16,17,18,19] Therefore, developing physical models, which will inherently reflect the main characteristics of the injection, wall wetting, evaporation and mixing, is paramount for predicting the amount of fuel available for combustion, which is directly linked to the torque output of the engine. The concept of model based engine calibration is not a new field of study [30,69]; however, it has received more attention recently for the above stated reasons. Some of the models rely heavily on experimental data and statistical inference, some rely on a semi-empirical model, [20,21,49] and some are based on experimental data and statistical inference for training a neural network based model [22].…”

The aim of this study was to implement Economic Order Quantity method (EOQ) together with the Lambert W function in a 1-D engine simulation model in order to develop a fuel control strategy for a Gasoline direct injection (GDI) engine. Previous work of the co-author demonstrated the possibility of optimizing fuel injection quantity in GDI engine using the EOQ that is commonly used in supply chain of perishable products. This work extends the previous work and implements it in a 1-D, crank angle resolved, engine simulation model for the application of model based calibration process. The present work uses a validated engine simulation model, which is based on predictive combustion modelling approach, and couples the 1-D engine simulation model with SIMULINK to add the evaporation, wall-wetting and heat transfer models. It employs FORTRAN subroutines to modify the internal code of the 1-D simulation software in order to add crank angle resolved evaporation model. Finally, EOQ with Lambert W function was added to the model using MATLAB with special attention to the decimal control for the solution. This study demonstrated that EOQ and Lambert W functions together are a suitable method to develop fuel control strategy for a model based calibration procedure when implemented in crank angle resolved 1-D simulation model.
