Automotive engine air-ratio plays an important role of emissions and fuel consumption reduction while maintains satisfactory engine power among all of the engine control variables. In order to effectively control the air-ratio, this paper presents a model predictive fuzzy control algorithm based on online least-squares support vector machines prediction model and fuzzy logic optimizer. The prop...

Hands-free operation of a mobile phone in car raises major challenges for acoustic enhancement algorithms and speech recognition engines. This is due to a degradation of the speech signal caused by reverberation effects and engine noise. In a typical mobile phone/carkit configuration only the car-kit microphone is used. A legitimate question is whether it is possible to improve the useful signa...

Author is pointing at the possibility of the utilisation of simulated computations for the research and development of the Car TDI diesel engines. Modern technical potential of them is discussed in the opening part of the paper with emphasis on the Latest Fuel Injection Technology. In this part of the paper one can find a short characteristics of the Engine, Exhaust Gas Recirculation, Selective...

Causal manipulation theorems proposed by Spirtes et al. in the context of directed probabilistic graphs, such as Bayesian networks, do not model so called reversible causal mechanisms, i.e., mechanisms that are capable of working in several directions, depending on which of their variables are manipulated exogenously. An example involving reversible causal mechanisms is the power train of a car...

Soil microbial communities play an important role in the biodegradation of different petroleum derivates, including hydrocarbons. Also other biological factors such as enzyme and respiration activities and microbial abundance are sensitive to contamination with petroleum derivates. The aim of this study was to evaluate the response of autochthonic microbial community and biological parameters (...

This paper describes a research project that uses embedded systems design principles to construct and simulate an Engine Control Unit (ECU) for a hybrid car. The ECU is designed to select a fuel type based on the stress level of the simulated engine. The primary goal of the project was to use a robotics kit, connected to sensors, to simulate a hybrid car under certain stress conditions such as ...

In this paper we propose a new engine management system for hybrid vehicles to enable energy providers and car manufacturers to provide new services. Energy forecasts are used to collaboratively orchestrate the behaviour of engine management systems of a fleet of PHEV’s to absorb oncoming energy in an smart manner. Cooperative algorithms are suggested to manage the energy absorption in an optim...

This paper gives an overview of the current industry based projects in the field of vehicle modeling and simulation in the Duisburg Mechatronics Laboratory. It shows the wide range of research fields covered in Duisburg, including vehicle systems, vehicle dynamics, occupant safety, adaptive cruise control, power steering, hardware in the loop, fault tolerant real time systems and tolerance anal...
