Fully Automatic Determination and Optimization of Engine Control Characteristics

Study on Optimization of the Diesel Engine Controlling Parameters Based on Genetic Algorithm

“…Through the cross and aberrance, a new group of genetic chromosomes adapt to the environment better was produced. The process evolved from generation to generation, and finally converged to one individual that best adapted to the environment, and seek problem solution [3,4]. The basis flow of genetic algorithm was shown in Fig.…”

Engine Test Data Modelling by Evolutionary Radial Basis Function Networks

“…The most popular mathematical models for this purpose are the tting of polynomials which are widely used in modelling engine test data [2][3][4]. However, the determination of the correct terms and coe cient ranges from the tested data for multivariate polynomial tting is a di cult task.…”

Online Control of Automotive systems for improved Real-World Performance

“…The deterministic optimisation approach is further subdivided into constrained and unconstrained optimisation methods. The constrained optimisation methods have been widely used in the literature for Diesel engine calibration where, the very popular are Lagrangian method [Hochschwarzer et al 1992 for such a deviation is that the driving cycles considered by regulations only represent to some extent the set of conditions that a vehicle may face during their entire life. To make-up for such a limitation, the current regulations have introduced RDE testing procedures as a method to reduce the gap between declared performance and that perceived by users.…”
