Integrated Simulation and Engine Test of Closed Loop HCCI Control by aid Variable Valve Timings

This doctoral thesis is about controlling the combustion timing of concept Homogeneous Charge Compression Ignition, HCCI, by means variable valve timings. The HCCI research usually regarded to have started in Japan during later part 1970´s. world has since grown and today researched worldwide. Of particular interest from a Swedish point view that Lund Institute Technology emerged as one leading laboratories. idea with combine Otto Diesel engine. As an engine charge premixed but operation...

Development of mechatronic products is traditionally carried out by several design experts from different domains. Performing development thus greatly challenging. In order to tackle this, the critical challenges in mechatronics have be well understood and supported through applicable methods tools. This paper aims at identifying major challenges, conducting a systematic thorough survey most relevant research work design. Solutions proposed literature are assessed illustrated case study...

Mechatronic design is traditionally supported through domain-specific activities throughout the product development process. The partitioning into problems leads to a situation where properties influence each other, hence giving rise dependencies. These dependencies play key role in prediction of and, as result, decision-making important question how manage for efficient and effective decision making? aim this paper threefold. First, we investigate nature study model them. proposes...

We try to get the heart of multidisciplinary engineering, which mechatronics is an excellent example, and point out how integration disciplines leads new degrees freedom in design corresponding research directions that otherwise would not have been investigated. This major contribution achieved by a approach engineering science; it important field at same time helps push related fields into fruitful directions. number areas benefited from interdisciplinary perspective focus on interactions...

This paper describes a novel approach to recognize and model assembly semantic knowledge enclosed in product features.The proposed is based on two stages: recognition modelling.In the first stage, internal boundary representation (B-rep) method utilized extract from CAD models using SolidWorks' API functions.In second multi-level generated.The characterized by separating geometrical data represented form features (basic topological entities such as holes, slots, notches etc.) (features...

Higher demands on efficiency, cost and functionality have contributed a great deal towards the advent of Mechatronic systems where mechanics, electronics computer software integrate together to provide required functionality. This integration has its effects in design process as well, good requires careful methods tools satisfy overlapping objectives. The set requirements designer needs for are all three domains, hence various modelling used by engineers these multi-domain requirements. With...

Hybrid electric vehicles have shown significant improvement for both fuel efficiency and emission reduction, attracted many researchers. Paramount the of HEVs is energy management control strategies. ECMS (equivalent consumption minimization strategy) one well-known real time power strategies has been used extensively in different works; however, its intrinsic difficulty to find optimal equivalent factor, which theory determined by a priori knowledge complete driving cycle. Different methods...

One of the main challenges with Homogeneous Charge Compression Ignition, HCCI, combustion system is to control Start Of Combustion, SOC, for varying load and external conditions. A method t ...

Tower cranes are commonly used at construction sites all over the world. These prone to swinging of cable suspended payload, resulting in unwanted payload oscillations that have severe effects on safety site as well operational speed and accuracy delivery. The nonlinear nature rotating crane motion makes controlling these a complex task. In this paper, time-optimal velocity control method is developed enable fast swing-free tower movements by applying Pontryagin's maximum principle set...

The wide range of engineering domains aggregated in mechatronic systems can cause problems for design engineers. It is important to treat the different an integrated, concurrent manner during be able achieve frequently sought-for synergetic effects systems. Traditional methods are usually based on disciplines being treated separately and only integrated at a late stage development process. Consequently, those do not work sufficiently well systems, leading suboptimal product. Previous...

This paper presents an innovative transmission called the passively variable (PVT) that has a high torque ratio for large loads and low velocity small loads. The change in these ratios depends on load, contrast to continuous (CVT), where is controlled explicitly. Another difference from CVT PVT elastic term therefore not applicable. A theory section formulates alternative ways of describing relations conservative transmisions as well other important properties. used analyze illustrate...

Purpose This paper introduces a schema for the product assembly feature data in an object-oriented and module-based format using Unified Modeling Language (UML). To link production with design, it is essential to determine at early stage which entities of design development are involved used automated planning operations. this end, absolutely reasonable assign meaningful attributes parts’ (assembly features) systematic structured way. As such, approach empowers processes such as motion...

The engine cooling system in trucks is one of the main sources parasite load. Thus fuel efficiency can be improved by optimal control thermal management considering consumption minimization as objective. Although several methods have been proposed for system, their emphasize on regulating and coolant temperature an acceptable range rather than minimizing consumption. In contrast, this paper investigates saving potential predictive conventional trucks. Our method exploits idea energy buffers...
