Hydrogen is the energy vector that will lead us toward a more sustainable future. It could be fuel of both cells and internal combustion engines. Internal engines are today only motors characterized by high reliability, duration specific power, low cost per power unit. The most immediate solution for near future application hydrogen as in modern This has advantages disadvantages: physical, chem...

Even in a scenario where electric vehicles gain market share and the sale of internal combustion engines is gradually reduced, at present time, there are still no real options that can totally replace (IC) engine over entire range its applications [...]

The use of hydrogen as a fuel for an internal combustion engines has caused many problems years, the most significant which seems to be excessive emission nitrogen oxides and tendency knock combustion. In order ensure better control process in engine powered by hydrogen, it been proposed split chamber solution. Following paper contains description system that includes analysis possible technica...

The increasing environmental awareness of the last decades has led to a huge tightening restrictions on vehicle pollutant and carbon dioxide emissions. Friction dissipation plays strategic role as its reduction necessarily leads decrease in CO2 Valve timing system is responsible for significant part overall friction losses provides relatively wide margin improvement. This regulates intake exhau...

To carry out increasingly sophisticated checks, which comply with international regulations and stringent constraints, on-board computational systems are called upon to manipulate a growing number of variables, provided by an ever-increasing real virtual sensors. The optimization phase ICE passes through the control these numerous often exhibit rapidly changing trends over time. On one hand, am...

The gases emissions measurement systems in internal combustion engines are strict and expensive nowadays. For this reason, a virtual instrument was developed to measure the combustion emissions from an internal combustion diesel engine, running with diesel-biodiesel mixtures. This software is called virtual instrument for emissions measurement (VIEM), and it was developed in the platform of Lab...
