It could be on sale by the end of 2008!

The 3.0-liter V6 dCi Concept engine was designed within the Renault-Nissan Alliance with Renault having much of the engineering responsibility and Nissan providing performance target settings and package optimization. The companies will market the engine separately in keeping with the Alliance commitment to maintain each company’s distinct brand identity.

Specifications for the engine to be used in the Maxima have not been fully determined.

The 3.0-liter V6 dCi Concept. The V6 dCi Concept is a preview of a coming new generation of 3.0-liter V6 diesel engines. The new 2,993cc block is derived from the 2.0 dCi engine, with which it shares 25% of its components. The engine develops 195 kW (261 hp) of power and maximum torque of 550 Nm (406 lb ft) at 1,750 rpm with targeted CO2 emissions of less than 200g/km.

The common rail fuel injection system uses two rails pressurized at 1,800 bar which supply 7-hole piezo-electric injectors. This configuration supports up to five injections per cycle. “Ultra-fast” ceramic technology glow plugs enable almost instantaneous preheating and cold starting.
The V6 dCi Concept also includes a variable geometry turbocharger, which generates a high level of torque even at very low revs.

The engine’s air intake ducts have been specially designed to increase combustion speed inside the cylinders by swirling the air in the cylinders—the swirl effect. Cooled EGR (Exhaust Gas Recirculation), which uses a Renault-patented air/water intercooler, contributes to overall environmental performance of the engine.

The architecture of the exhaust manifolds has been designed to limit load losses and ensure that the maximum amount of energy is delivered to the turbine.

The V6 dCi Concept introduces a new NOx trap. Alongside the catalytic converter, this device is located on the exhaust line between the turbocharger and the particulate filter. The engine is also fitted with a maintenance-free, periodic regeneration particulate filter, which operates using a seventh fuel injector located upstream of the filter. Regeneration occurs automatically, with no need for intervention from the user.

  1. Εντυπωσιακός κινητήρας με εντυπωσιακές επιδόσεις!!!
    Η ενεργειακή κρίση, καθώς και η αύξηση της τιμής του πετρελαίου ωθούν τις εταιρίες στην έρευνα και ανάπτυξη ιδιαίτερα αποδοτικών κινητήρων. Ένα ακόμη παράδειγμα είναι ο κινητήρας Dieotto ο οποίος συνδυάζει τους κύκλους Diesel και Otto όπως λέει και το όνομά του. Με καύσιμο τη βενζίνη πετυχαίνει επιδώσεις και κατανάλωση diesel.
    Νομίζω ότι στα χρόνια που έρχονται θα δούμε πράγματα που θα τρίβουμε τα μάτια μας.
    Μην ξεχνάμε ότι η Audi κέρδισε τον αγώνα του Le man με κινητήρα Diesel!

    Μοτερούκλα…56 κιλά από τις 1500 μέχρι τις 3500…

    Πραγματικά εντυπωσιακές προδιαγραφές.
    Μακάρι να μπει στο Patrol, και να αποδειχτεί αξιόπιστος.

    Q, πες μας λεπτομέρειες για αυτό το Dieotto, τι παίζει?
