Ford Fiesta / Ford Focus EcoBoost Hybrid 2019
nella discussione ha aggiunto Beckervdo in Ford Europa
Saranno presentate al Salone dell'Auto di Amsterdam le nuove Ford Fiesta e Ford Focus EcoBoost Hybrid. Le due vetture saranno disponibili sul mercato alla fine del 2019. Il motore è il 3 cilindri 1.0 Ecoboost a cui è abbinato un sistema moto-generatore (al posto di alternatore e motorino di avviamento) che ricarica una batteria gli ioni di litio con una tensione operativa di 48V. In questo modo è stato possibile adottare un turbocompressore più grande, poiché per il "lag" interviene la spinta del moto-generatore. Ford dichiara un consumo medio di 4.9 litri / 100 km ed emissioni di 112 g/km per la Fiesta EcoBoost Hybrid e 4.7 litri / 100 km ed emissioni di 107 g/km di CO2 per la Focus EcoBoost Hybrid.

Continental: nuovo Mild-Hybrid a 48 V e 30 kW
nella discussione ha aggiunto Beckervdo in Elettrificazione e Tecnologie per l'Ambiente
The 48-volt systems were previously known as mild or P0 hybrids. They involve relatively unobtrusive electrification of the powertrain. Fuel consumption is reduced mainly with the support of the combustion engine (boosting) during acceleration and the recovery of excess kinetic energy (recuperation) when the vehicle decelerates. However, purely electric driving is not possible with such systems, which Continental already manufactures for a number of automotive manufacturers. In the latest stage of development, the 48-volt system was repositioned in the powertrain. The electric motor was no longer placed in front of the combustion engine on the crankshaft, but behind it—between the combustion engine and transmission (P2 hybrid). This meant that fuel savings were able to increase and, in certain situations, such as driving through a 30 km/h speed limit zone, the vehicle could be driven using the electric motor alone. With the new 48-volt high-power technology, this hybrid system enables the same functionality as previous, full-hybrid vehicles. The key component here is a new, water-cooled electric motor, the peak output of which was doubled to 30 kW in comparison with that used previously. Electric-only driving is therefore possible up to a speed range of 80 to 90 km/h. 8-volt high-power electric motor with a peak output of 30 kW. The developers were able to achieve a 100% increase in power while maintaining the diameter of the motor. Overall, 48-volt high-power technology requires only slightly more installation space than the previous system. The difference in weight is also minimal. However, the electric motor is not the only new component of the 48-volt high-power technology. The integrated power electronics also uses a new technology that now enables it to handle significantly higher currents. The innovations of the new 48-volt high-power technology result in a level of electrical efficiency that surpasses the previous system by almost 10%. During recuperation, the new technology is much more effective than was previously the case because the losses incurred in the electric drive system has been halved. A 48-volt system requires considerably less effort in terms of insulation protection, electrical components are smaller and cheaper, and even the design can be made significantly more compact, because smaller gaps are required between the individual components than is the case with high-voltage technology. Continental is showcasing the new 48-volt high-power technology, which is also ready for series development, in a Ford Focus test vehicle. With an eye on the new approval regulations that have been in force since 1 Septembe 2018, in accordance with the WLTP cycle, the 48-volt high-power technology could be developed even further. If, for example, the system was supplemented by on-board charging technology and a larger battery, this would make even a plug-in hybrid drive featuring 48-volt technology possible. This is because the ability to drive in all-electric mode is no longer the main criterion for benefiting from the support for plug-in vehicles. Instead, it is the conversion of electrically stored energy into traction in general. The deciding factor for different funding initiatives is whether CO2 emissions can be reduced to below 50 g per kilometer. Via GreenCarCongress -
KIA: EcoDynamics+ Il diesel con sistema 48V
nella discussione ha aggiunto Beckervdo in Innovazione Meccanica
Kia tiene vivo il propulsore Diesel, lanciando in Europa il pacchetto EcoDynamics+ al debutto sulla rinnovata Sportage 2018. Il sistema è completamente versatile: può esser abbinato alla trazione anteriore o integrale, alla trasmissione manuale o automatica. Il nuovo motore diesel è associato ad un sistema ibrido-leggero con impianto dedicato da 48V a cui è associato un motore elettrico. Rispetto al precedente propulsore diesel (non si dichiara se il 1.7 o il 2.0 litri) i consumi scendono del 4% rispetto al precedente e con omologazione Euro6d-Temp e cicli RDE / WLTP. Il motore termico può svolgere due funzione: ricarica delle batterie (generatore) o esser aiutato dal comparto elettrico. Il motore integrato nel sistema generatore ISG, eroga un plus di potenza di 10 kW. Di più "nin 'zo" Via Autoblog.nl- 22 risposte
