“…The high oxygen content can also lead to an over-lean mixture at low load when global equivalence ratio is already low. In this case the strong latent heat of vaporization can be an added negative point leading to a slow vaporisation, a lower flame temperature [13] and so an incomplete combustion and consequently higher HC and CO emissions [14][15][16][17][18]. A longer mixing process could also occurred due to the modified auto-ignition properties (poor Cetane Number of ethanol).…”

“…Some further analysis and studies concerning injection scheme or pilot injection timing effects at different engine speeds and loads were presented in previous references [10,16,19,20]. Beyond the PM emissions reduction partly due to the oxygenated content of this alternative fuel, these analyses lay down guidelines for recalibration and prove the potential benefits of updating the engine settings to improve the engine/fuel matching.…”

“…The combination of increased EGR rate and decrease of injection pressure seems necessary to manage this issue as well as decreasing further NO x emissions. The main characteristics of the injection (scheme, duration of each injection, dwell time) should be modified in order to ensure a proper pilot injection combustion for example, as explained also in previous publications [16,19,20]. Therefore, to illustrate this last statement it was decided to focus on some dwell times sweep between pilot and main injections (with a reduction of 750 μs until an increase of 500 μs of this time); they are performed at 2 000 rpm, BMEP 4 bar.…”

Résumé -Utilisation d'un carburant Diesel éthanolé à l'aide de méthodes de calibration avancées afin de satisfaire les normes Euro 5 sans filtre à particules -L'utilisation des biocarburants s'est développée durant ces dernières années de façon importante afin de diversifier les sources d'énergies et de limiter la hausse des émissions de gaz à effet de serre du secteur des transports. L'un des carburants renouvelables les plus adaptés à une production de masse est l'éthanol. Celui-ci est aujourd'hui principalement utilisé dans les moteurs à allumage commandé, alors que la part des véhicules Diesel sur le marché européen est de l'ordre de 60 %. Ce constat nous a incité à proposer une formulation innovante utilisant de l'éthanol pour les applications Diesel. Les principaux verrous technologiques pour cette utilisation sont la miscibilité, la température d'éclair, la lubrification ou encore l'indice de cétane. Des travaux ont été réalisés pour optimiser la formulation contenant de l'éthanol, des biodiesels de première et seconde générations. Appliqué à un véhicule optimisé pour la norme Euro 4, ce carburant oxygéné a permis une diminution drastique des émissions de particules. Il a été cependant observé que les émissions de HC et de CO peuvent être problématiques tout autant que celles de NO x si les paramètres du contrôle moteur ne sont pas adaptés. Des analyses de combustion apportent une aide à la compréhension de ces résultats par l'étude du délai d'autoinflammation ou encore de la combustion de l'injection pilote. Ainsi, au banc moteur, des méthodes avancées de calibrations telles que les plans d'expériences ont été utilisées pour optimiser l'adéquation moteur/carburant. Une approche de type global a été proposée et comparée à une approche locale plus classique. Cette optimisation à chaud permet une réduction simultanée des émissions de NO x et de particules. Ces résultats laissent également présager une réduction du bruit de combustion et des émissions de CO 2 sur véhicule. Un banc moteur dynamique a été ensuite utilisé pour étudier plus en détail le potentiel de réduction des émissions polluantes. Le comportement d'un véhicule sur le cycle européen NEDC avec démarrage à froid a pu être reproduit. Différentes méthodologies innovantes, basées notamment sur l'optimisation simultanée des cartographies de base et des cartographies de correction à froid, sont présentées. Elles permettent d'adapter les réglages du moteur par rapport à l'impact que ce carburant alternatif peut avoir sur la combustion et l'activation du catalyseur ou les émissions de HC et CO à la source. Ces méthodes ont permis de limiter le travail sur véhicule au banc à rouleaux à la validation des résultats obtenus sur banc moteur et à l'optimisation finale des cartographies à froid. Cette étude a prouvé qu'il était possible de satisfaire les normes Euro 5 avec cette nouvelle formulation de carburant tout en conservant une configuration de véhicule Euro 4 sans filtre à particules. En définitive, ce carburant innovant apparaît comme une solution i...

“…However, with the use of a cetane improver, a decrease in both ignition delay and cylinder peak pressure were achieved, thus reducing combustion noise. Magand et al [57] found a drop of combustion noise with the use of ethanol/diesel fuel blends in a multi-cylinder turbocharged diesel engine, improving engine behavior. Michikawauchi et al [58] studied exhaust and noise emissions under the New European Driving Cycle (NEDC).…”

The growing demand for fossil fuels, the rise in their price and many environmental concerns strengthen the incessant search for fuel alternatives. Recently, traffic noise has been described as a threat to human health and the environment, being responsible for premature deaths. In this context, the usage of alcohol/diesel fuel blends in diesel engines has gained increasing impact as a substitute fuel for use in internal combustion engines. Moreover, alcohol can be derived from environmentally friendly processes, i.e., fermentation. Furthermore, alcohols can enhance combustion characteristics due to a rise of the oxygen concentration, thus decreasing major emissions such as soot and reducing knock. The commonly used alcohols blended with diesel fuel are methanol and ethanol, recently followed by butanol. In contrast, there are very few studies about propanol blends; however, emissions reduction (including noise) could be remarkable. In the present work, an analytical literature review about noise and exhaust emissions from alcohol/diesel fuel blends was performed. The literature review analysis revealed a continuous increase in the number of publications about alcohol/diesel fuel blend exhaust emissions since 2000, confirming the growing interest in this field. However, only few publications about noise emission were found. Then, an experimental case study of noise emitted by an engine running on different alcohol (ethanol, butanol and propanol)/diesel fuel blends was presented. Experimental results showed that although diesel fuel provided the best results regarding noise emissions, butanol displayed the least deviation from that of diesel fuel among all tested alcohol blends. It may be concluded that tested alcohol/diesel fuel blends in general, and butanol blends in particular, could be a promising alternative to diesel fuel, considering noise behavior.
