The proton exchange membrane fuel cell (PEMFC) stack is a key component in the cell/battery hybrid vehicle. Thermal management and optimized control of PEMFC under real driving cycle remains challenging issue. This paper presents new vehicle model, including simulations diver behavior, dynamic, unit, energy stack, cooling system, battery, DC/DC converter, motor. model had been validated against...

Laminated composites are increasingly used in aeronautics and the wind energy industry, as well as in the automotive industry. In these applications, the construction and processing need to fulfill the highest requirements regarding weight and mechanical properties. Environmental issues, like fuel consumption and CO₂-footprint, set new challenges in producing lightweight parts that meet the hig...

In the early era of microcomputer-based automotive electronics, a separate ECU was developed for each functional unit such as engine management or transmission control. Coordination with the other ECUs was implemented via control lines, e.g. lines carrying pulsewidth modulated signals. Growing functionality, however, was driving the number of control lines and their costs upwards. That is why, ...

Environmental regulations and drivability issues are driving forces in the development of control systems for automotive engines. Precise control of the air and fuel is fundamental for achieving the goals. Furthermore, the architecture for the controller plays a central role in how the goals are achieved. A comparison is made between two conventional controller structures and a model based stru...

This paper deals air to fuel ratio control of a spark ignition engine, whose pollutant is a major cause of air pollution. A direct adaptive control using Gaussian neural networks is developed to compensate transient fueling dynamics and measurement error in mass air flow rate into the cylinder. The transient fueling compensation method is coupled with a dynamic sliding mode control technique th...

Around the world there is an increasing tend to introduce regulations concerning the environmental impact of products. In the automotive industry legislation has concentrated on exhaust emissions. Initially on-highway applications were regulated, but now attention has spread to include off-highway vehicles. This paper examines the impact of legislation on diesel engine manufacturers. They have ...

The production of synthetic fuels from alternative sources has increased in recent years as a cleaner, more sustainable source of transport fuel is now required. The European Commission has outlined renewable energy targets pertaining to transport fuel which must be met by 2020. In response to these targets Ireland has committed, through the Biofuels Obligation Scheme of 2008, to producing 3% o...

This paper presents a case study of the application of a data-driven monitoring technique to diagnose air leaks in an automotive diesel engine. Using measurement signals taken from the sensors/actuators which are present in a modern automotive vehicle, a data-driven diagnostic model is built for condition monitoring purposes. Detailed investigations have shown that measured signals taken from t...

Natural fibers have recently become attractive to automotive industry as an alternative reinforcement for glass fiber reinforced thermoplastics. The best way to increase the fuel efficiency without sacrificing safety is to employ fiber reinforced composite materials in the body of the cars so that weight reduction can be achieved. Designing the structures with the focus on improvement aspects i...

In order to help the introduction on the automotive market of polymer electrolyte fuel cells (PEFCs), it is mandatory to develop highly performing and stable catalysts. The main objective of this work is to investigate PtNi/C catalysts in a PEFC under low relative humidity and pressure conditions, more representative of automotive applications. Carbon supported PtNi nanoparticles were prepared ...
