[EN] Control strategies such as variations in injection pressure and timing have been used by researchers to reduce in-cylinder exhaust emissions and meet legislation standards. Postinjection has been studied for several ...

[EN] In-cylinder pressure analysis is a key tool for engine research and diagnosis and it has been object of study from the beginning of the internal combustion engines. One of its most useful application is combustion ...

[EN] This last few years, the trend in diesel engines has been to use different kinds of fuels to identify their influence and behaviour on the emissions and performance. Among the wide variety of fuels employed are the ...

Emission legislation together with the need of more fuel-efficient engines have driven the development of promising combustion concepts in compression ignition (CI) engines. Most of them, lead toward a lean and low temperature ...

[EN] In this work is underlined the importance of the optical techniques in the mark of the investigation on internal combustion engines. The document reports an example of application of different optical techniques for ...

[EN] Evaporating diesel sprays from three different multi-hole nozzles have been studied by means of three different and complementary techniques: Mie scattering, double-pass schlieren, and CH radical chemiluminescence. ...

Despite their important advantages in terms of fuel consumption in comparison with gasoline engines, for a long time the characteristic impulsive combustion noise has been one of the main causes why customers are reluctant ...

Combustion simulation in two-stroke engines becomes necessary not only for engine performance prediction but also for scavenge evaluation, since in-cylinder pressure and temperature are highly influenced by combustion ...

[EN] The development and optimization of new combustion modes is nowadays an important research field, to reduce the pollutant emissions of the reciprocating internal combustion engines. Their development requires the use ...

Rice fields contribute substantially to global warming of the atmosphere through emission of methane (CH4). This article reviews the state of the art of factors affecting CH4 emissions in rice fields, focusing on soil ...
