Abstract: In spark ignition engine (SI engine), the mixture of air and fuel is usually formed outside of the cylinder and ignited by a spark plug. Basing on the way of energy-accumulation, there are two types of ignition systems: capacitive discharge ignition system (CDI) and transistorized ignition system (TI). Although the two types of ignition system are different, they have provided the same high-voltage pulse. This paper attempts to represent a hybrid ignition system that could be used in two distinct types of ignition system with a programmable controller. According to the range of activation of the engine, the controller automatically select between CID or TI system in the optimization of consumption of fuel. Experiment results of the research shows that the hybrid ignition system could reduce the fuel consumption up to 55g per 100km. The CO and HC levels are also reduced to 0.02%.

Abstract: Although the research and development of nanocomposites for almost a decade focused on structural properties, these properties remained until today far below expectations, which were forecast at the beginning of the new millennium. However, even if it is well known that the processing history has a major impact on the structure and properties of final components, this aspect was not subject of intensive research in the past. The talk focuses on the role of the manufacturing sequence on the morphology and properties of polypropylene based nanocomposites. In general it can be stated that the incorporation of nano-sized TiO2-fillers improves the some mechanical properties of the resulting nanocomposites as long as the production enables a good dispersion and distribution of the nanofiller agglomerates. However, with increasing filler loading, the morphology of injection molded parts changes: The size of the spherulites and the degree of crystallinity decreases while the crystallization/so
