Η Nissan ανακοίνωσε πως το Juke πλέον θα είναι διαθέσιμο με τον ανανεωμένο 1.5 dCi κινητήρα ο οποίος αποδίδει 20 Nm επιπλέον ροπής, φτάνοντας τα 260 Nm, ενώ έχει γίνει και πιο αποδοτικός. Διαθέτει start/stop, νέες κλιμακώσεις στο κιβώτιο και μειωμένο θόρυβο του κινητήρα, έχοντας μέση κατανάλωση 4,2 λίτρα/100 χλμ και 109 γρ/χλμ εκπομπές CO2.
Το 80% της ροπής είναι διαθέσιμο από τις 1.500 σ.α.λ με τον κινητήρα να αποδίδει 110 άλογα με τα 0-100 χλμ/ώρα να τα κάνει σε 11,2 δευτερόλεπτα έχοντας τελική ταχύτητα 175 χλμ/ώρα.

NEW ENGINE FOR NISSAN JUKE
New generation 1.5 dCi engine gives Nissan’s compact crossover more torque, better fuel economy and lower emissions
- New generation 1.5dCi has…
• Engine torque increase by 20Nm to 260Nm
• Fuel economy improvement from 4.8l/100km to 4.2l/100km
- CO2 emissions reduced to just 109g/km
- Stop/Start now standard
- Revised gear ratios for improved drivability and fuel efficiency
- Reduced engine noise for greater refinement
ROLLE, Switzerland (11th June, 2013) – More torque, greater fuel economy, lower emissions, reduced noise and the adoption of Stop/Start – these are just some of the benefits of the latest 1.5dCi engine now fitted to the Nissan Juke.
A new generation version of the award-winning direct injection diesel engine, developed by Nissan’s Alliance partner Renault, makes Juke more efficient, more refined and even greater fun to drive.
Of the 330,000 Juke models sold since its launch at the end of 2010, more than 132,000 examples – some 40 per cent of all sales – have been powered by the 1.5dCi. The arrival of the new engine, therefore, could not be more significant.
Now in its sixth generation, the changes have boosted the engine’s maximum torque by a significant 20Nm to 260Nm, 80 per cent of which is available from as low as 1,500rpm, for improved driveability. And with CO2 emissions of just 109g/km and a combined cycle fuel economy figure of 4.2l/100kms, the new generation unit is the most efficient engine in the Juke line-up.
The improvements have been achieved following a host of technical changes. These include the adoption of revised piezo-electric fuel injection nozzles, which now have a more precise spray pattern for better combustion (with as much as 15% less unburnt fuel) and a new, more responsive, low-inertia variable geometry turbocharger fed by a more direct – and more efficient – air intake path.
In addition, the adoption of a closed-loop low-pressure exhaust gas recycling (EGR) system, in which the exhaust gas is cooled before being re-introduced to the intake system, has helped ensure the unit is compatible with forthcoming Euro6 emission regulations.
Other changes include a new thermostatically-controlled variable displacement oil pump which reduces internal friction by adapting automatically to the engine’s needs and oil viscosity.
And following the lead set by engineers responsible for Nissan’s highly efficient petrol engine, the new diesel features low friction enhancements including the adoption of diamond-like carbon (DLC) coatings for the tappets, technology inspired by Formula 1.
The engine also now features Nissan’s automatic Start/Stop system, with highly efficient smart management technology which ensures the engine restarts within 0.5sec of the clutch being engaged. Reduced combustion noise further enhances the unit’s overall refinement.
Changes have also been made to the gear ratios. The 1st and 2nd ratios are a little shorter to allow sharper responses at low speeds and enhancing Juke’s natural fun-to-drive attitude, while the remaining four ratios are slightly longer, taking advantage of the improved torque to deliver better fuel efficiency. Over the combined cycle, the new Juke 1.5dCi returns 4.2l/100km as opposed to the previous unit’s 4.8l/100km, a 12.5% improvement.
Fuel efficiency is also helped by the use of the Nissan Dynamic Control system, which enables the driver to select from three mode engine settings – Eco, Normal and Sport. This system now not only selects appropriate pedal sensitivity settings in Eco and Sport modes, but also limits maximum engine torque in Eco mode to 220Nm… though the full 260Nm is available in kick-down.
The unit’s overall power output remains at 110PS (81kW) while performance figures (175kph max, 11.2sec 0-100kms) are also unchanged.
The new generation engine will be available across all Juke grades including the special n-tec version, which showcases new technology such as the latest Nissan Connect communication centre.
As well as new navigation software, the system incorporates advanced features such as Google Send-To-Car technology, which allows an owner to plan a journey on their PC or tablet at home or in the office and then send the instructions to the car ahead of the trip.
“As well as the obvious advantages of lower emissions and improved fuel efficiency, the higher levels of torque from the new engine mean greater flexibility and more refined cruising as well enhanced in gear performance around town,” said Paul Wilcox, Senior Vice President, Sales and Marketing Nissan in Europe.
