More attractive interior styling
Dacia Logan sedan inaugurate the new dark charcoal or two-tone well-equipped, modern dashboard (depending on model and version) which features chrome instrument bevels and particularly functional, latest-generation controls.
The air vent surrounds, logo on the steering wheel and gear lever knob are all picked out in chrome (depending on equipment level), while the bottom edge of the central fascia features a coloured trim (depending on finish) that harmonises with the door pulls and decorative steering wheel insert.
Meanwhile, special attention has been paid to ensuring an immediate impression of quality which is reinforced by the materials selected for the interior and by the more careful fit-and-finish.
Reduced load losses thanks to an innovative turbo architecture: the path that intake air must travel has been simplified to achieve more efficient, uprated turbo performance with no increase to fuel consumption.
- Low inertia turbo: improved response at low engine speeds thanks to the optimised size of the blade.
Individualised spray cone angle fuel injection nozzles: the more precise spray pattern significantly improves combustion performance (15 percent less unburned fuel), which in turn has a beneficial effect on fuel consumption and CO2 emissions. Individualised spray cone angle technology compensates the natural nozzle offset inherent in eight-valve engines due to the asymmetry of the intake and exhaust valves. Injection is ensured by seven-hole piezoelectric injectors.
Reduced friction: Friction-related energy losses have been reduced, meaning that less fuel is required to deliver the same quantity of energy. Other benefits are longer engine life and enhanced robustness.
Features carried over from the Energy dCi 130 engine's 'technology package':
- Stop & Start technology with braking/deceleration energy recovery (ESM) involves automatically cutting the engine when the vehicle is at a standstill since the engine clearly doesn't emit any pollutants or CO2.when it isn't running. When driving exclusively in built-up areas, fuel savings can amount to more than one litre per 100km. When the driver presses on the clutch pedal again, the engine fires up instantly. To cope with all this repeated starting, the starter motor has been uprated (starter, starter ring gear), as has the fuel injection system (pump and high-pressure injectors). The engine has been engineered for 410,000 starting cycles (over 300,000km), which is almost seven times more than the same figure for a conventional engine.
EGR (Exhaust Gas Recirculation): Renault has innovated with the launch of the European market's first engine to feature low pressure EGR technology. This solution recovers exhaust gases further downstream, once they have been through the turbine and particulate filter. They are cooled in a low pressure intercooler which enables them to be recirculated through the turbo mixed with air and thereby increase turbo pressure. The gases are then cooled by air in the turbo radiator and used for combustion a second time. This so-called 'cold loop' enables emissions of nitrogen oxides to be cut more efficiently than is the case with a conventional high pressure EGR (see below), while engine efficiency is improved and combustion is of a higher quality. Low pressure EGR technology calls for an engine architecture that minimises the distance between the catalytic converter/particulate filter and the air intake, an arrangement known as a post-turbo after-treatment system. This proximity enables:
- Catalytic converters and particulate filters to function at higher temperatures and therefore more efficiently,
-The design of a compact and efficient low pressure EGR circuit.
- Catalytic converters and particulate filters to function at higher temperatures and therefore more efficiently,
-The design of a compact and efficient low pressure EGR circuit.
