Το νέο Mazda6 θα ξεκινήσει τις πωλήσεις του από πρώτο τρίμηνο του 2013 και από την αρχή θα διαθέτει το σύστημα ανάκτησης ενέργειας κατά το φρενάρισμα i-ELOOP. Το Mazda6 θα γίνει το πρώτο αυτοκίνητο της Mazda το οποίο θα φορά αυτό το πρωτοποριακό σύστημα ανάκτησης ενέργειας κατά το φρενάρισμα, μιας και αυτό δεν χρησιμοποιεί μπαταρία, αλλά πυκνωτή. Το όνομα του προέρχεται από τις λέξεις (Intelligent Energy Loop) και βελτιώνει την οικονομία καυσίμου κατά 10%.


Η μεγάλη διαφορά με τα μέχρι τώρα συστήματα, είναι ότι το σύστημα της Mazda, αντί για μπαταρίες, χρησιμοποιεί πυκνωτή, που μπορεί να αποθηκεύσει προσωρινά μεγάλες ποσότητες ηλεκτρικής ενέργειας. Σε σύγκριση με τις μπαταρίες, οι πυκνωτές μπορούν να φορτίσουν και να αποφορτιστούν γρηγορότερα και έχουνε μεγαλύτερη διάρκεια ζωής. Το i-ELOOP μετατρέπει την κινητική ενέργεια σε ηλεκτρική κατά το φρενάρισμα, και την χρησιμοποιεί για να τροφοδοτήσει το σύστημα κλιματισμού, το σύστημα ήχου καθώς και άλλα ηλεκτρικά μέρη του αυτοκινήτου. Το i-ELOOP συνεργάζεται και με το σύστημα i-stop της Mazda και έτσι βελτιώνεται η οικονομία καυσίμου.

Παράλληλα η Mazda ανακοίνωσε ότι το Mazda6 θα κατασκευάζεται και στη Κίνα, από το εργοστάσιο της κοινοπραξίας της FAW-Mazda. Η εγχώρια παραγωγή θα ξεκινήσει από το δεύτερο εξάμηνο του 2013 και όσα αυτοκίνητα θα κατασκευάζονται εκεί, θα πωλούνται στη τοπική αγορά.

Τέλος, η Mazda ανακοίνωσε και τις πωλήσεις της για το πρώτο 11μηνο του έτους όπου συνολικά έχει πουλήσει 1.090.962 αυτοκίνητα (+2,1%) ενώ μόνο τον Νοέμβριο πούλησε 96.835 αυτοκίνητα (-10,3%). Αναλυτικότερες λεπτομέρειες μπορείς να βρεις στο δελτίο τύπου που ακολουθεί.

HOW i-ELOOP DEFIES CONVENTION TO GIVE CLEANER MOTORING

  • Lightweight capacitor saves engine power and boosts fuel economy
  • Launches with all-new Mazda6
  • Standard fit across the majority of all-new Mazda6 models

The best way to harvest what is essentially ‘free’ engine power under braking or when running on a trailing throttle for example, has challenged engineers for decades.

The most common solution is brake energy regeneration: capturing kinetic energy (the energy generated by a vehicle when it moves) that would otherwise be lost when slowing down. This energy is used to recharge batteries in electric and hybrid cars, for example, or to power the on-board electrical network and save engine power and therefore save fuel.

Such systems have been in use for some years – Formula One racing cars started to use them in 2009 – but Mazda’s system is unique. i-ELOOP (short for “intelligent Energy Loop”) is the world’s first passenger car system to use a capacitor to store the electricity.

The all-new Mazda6 is the first of Mazda’s SKYACTIV technology models to be available with i-ELOOP.

“The i-ELOOP capacitor is a unique solution to the challenge of how to harvest free engine power,” explains Mazda Motors UK Managing Director Jeremy Thomson.

“One of the benefits of energy recovering systems is that they allow ancillary systems such as air-conditioning to be used without drivers having to worry about the detrimental effect on fuel consumption,” Thomson added.

“i-ELOOP is launched as part of Mazda’s ‘building block’ strategy, a step-by-step introduction of auxiliary electrical systems to SKYACTIV technology, allowing new breakthrough initiatives to be added as and when they are ready,” said Thomson.

A typical vehicle deceleration phase lasts only about 10 seconds. Realising that the effectiveness of regenerative braking systems to date has been limited by the charging and storage drawbacks of conventional lead-acid starter batteries, Mazda engineers adopted an electric double-layer capacitor (EDLC), which recharges fully in only a few seconds. An efficient 12V-25V variable voltage alternator generates the electricity and charges the EDLC; a DC/DC converter then steps down the voltage to power electrical components such as the climate control air-conditioning and audio systems, with any surplus going to the starter battery.

A full capacitor charge is enough to run the vehicle’s electrical systems for a minute or so. This makes i-ELOOP the perfect companion for i-stop – the latter launched as standard on the Mazda CX-5 and the all-new Mazda6 – as there is no need to revert to battery power even when Mazda’s idle-stop system has shut the car off. During stop-and-go city driving, charging often resumes before the capacitor is fully discharged. i-ELOOP can therefore produce most if not all of a vehicle’s electricity needs, whereas normally some of the engine’s output is required just to drive the alternator. By freeing up this engine capacity, i-ELOOP increases fuel economy under everyday driving conditions.
