Ahi pone Megane range, es decir, que terminará acabando en el Megane ¿no?. Supongo que en el phII o en el Megane IV, aunque yo espero que sea ya en el primero…

Bueno, los dos motores llegan el año que viene al Megane

The 1.5 dCi metamorphosis

[youtube youtube=425,350]1wj-Hy5eKtM[/youtube]

The Energy dCi 110 engine is a real jewel of technologies. Its evolutions compared to the 1.5 dCi engine are: a turbocharger architecture, an individualised spray cone angle and reduced friction, as well as a carryover of the Energy dCi 130’s ‘technology package’.
Energy dCi 110 offers reduced load losses thanks to an innovative turbo architecture. The path where intake air travels, has been simplified to achieve more efficient, uprated turbo performance without increasing fuel consumption. Moreover, a low inertia turbo improves response at low engine speeds thanks to the optimised size of the blade.

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.

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.

An engine fitted for the Energy family
Features carried over from the Energy dCi 130 engine’s ‘technology package’ revolve around 3 main technologies:

    Stop & Start technology with braking/deceleration energy recovery (ESM) involves automatically cutting the engine when the vehicle is at a standstill. 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. ESM (Energy Smart Management) is a system that allows the kinetic energy produced under deceleration/braking to be recovered by the alternator and stored in the battery. Functions which consume electricity (heater, lights, radio, etc.) are directly fed by the battery to ease the work of the alternator. Recovered energy is notably employed to restart the vehicle.
    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, 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.
    Thermostat-controlled automatic-flow rate oil pump: the capacity of the oil pump (and therefore oil pressure) is adjusted as a function of the engine’s needs at any given moment in order to reduce the pump’s energy consumption. An oil temperature sensor makes real-time adjustments to minimise viscosity-related friction, which has a beneficial knock-on effect on fuel consumption.

Sober and environment-friendly
The Energy dCi 110 engine offers fuel consumption savings and reduced CO2 emissions thanks to torque increase of 20Nm to 260Nm, available from as low as 1,750 rpm. The power output remains unchanged with 110 hp at 4,000 rpm.
Thus equipped, Mégane Energy dCi 110 becomes a new spearhead for the range with CO2 emissions as low as 100g/km, equivalent to fuel consumption of just 4 litres/100km.
The catalytic converter/particulate filter arrangement and low pressure EGR technology facilitate the engine’s conversion to Euro 6 legislation. To the same end, the compression ratio has been increased from 15.2:1 to 15.6:1.

ENERGY TCE 115

[youtube youtube=425,350]zFj-LzVU7TU[/youtube]

The Energy TCe family marks a fresh development in Renault’s petrol engine strategy and is expected to account for 85 per cent of the brand’s petrol engine sales in Europe by 2015. The Energy TCe 115 is a 1.2-litre engine with unprecedented performance and a model of fuel efficiency.

The best power

The Energy TCe 115 engine is equipped with a low-friction timing chain.

This brand new engine is poised to appear in the first half of 2012, initially in the Mégane and Scénic range where it will gradually replace the 1.6 16V 110hp (type K4M). Compared with the latter, it will represent an uprated performance package despite its 25 percent smaller cubic capacity:

    a turbocharged four-cylinder 1.2-litre engine (1,198cc) with direct injection.
    maximum power of 115hp (plus 5hp).
    peak torque of 190Nm (plus 40Nm) at 1,750 rpm, with 90 percent available from 1,500 rpm;
    reduction in fuel consumption by 25 per cent. That works out as a saving of more than 1.5 litres/100km compared to the engine it replaces and will give the car a range close to that of a diesel.
    running costs will also take a significant plunge thanks to the combination of its timing chain and low fuel consumption and CO2 taxes.
    new-generation downsizing: on an all-aluminium block, an unprecedented specific power of 100hp/litre for a 1.2 petrol engine. A three-cylinder, 900cc 90hp TCe engine will soon be marketed showing it is a modular family.

Performance-improving, efficiency-enhancing technologies
Renault’s first turbocharged, direct-injection petrol engine – the Energy TCe 115 – is particularly responsive. Thanks to peak torque of 190Nm, a figure worthy of a two-litre powertrain and available from as low as 1,750rpm, the Energy TCe 115 delivers the acceleration and mid-range response expected of a 1.6-litre engine.
This has been made possible thanks to a range of new technologies, some of which come from the world of F1:

    ‘Square’ engine architecture: takes up less space yet delivers the same performance
    1. 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.

    2. Variable-rate oil pump: oil pressure is electronically monitored and adjusted as a function of how the engine is being used. The benefit to the customer is lower fuel consumption and CO2 emissions.

    3. Low-friction timing chain: this optimised timing chain is equipped with a hydraulic tensioner which keeps it permanently taut to minimise friction.

    4. Graphite-coated piston skirtsDLC (Diamond Like Carbon) coated cam followers, a technique that has been employed in F1 for some years. Benefits are significantly reduced friction and enhanced energy efficiency for uprated performance and improved fuel consumption.

    Direct fuel injection: fuel is injected directly into the combustion chamber to optimise efficiency by carefully adapting the strategy as a function of how the engine is being used. The result is improved combustion and, consequently, lower fuel consumption and CO2 emissions. Double cam-phasing
    Variable Valve Timing (VVT). Combined with an integrated turbo manifold, VVT ensures that maximum torque is available at low engine speeds and across a broad rev-band.
    Stop & Start with ultra fast start-up: at a standstill, the system automatically detects the position of each piston and injects fuel into the most favourably-placed cylinder, in the same way as a cyclist presses on the uppermost pedal when pulling away. Re-starting is instan

The expertise of Renault Sport F1 channelled for the Energy TCe 115

Renault has sought to dial Renault Sport F1’s technological excellence into the design of its Energy engines. The Powertrain Engineering Department has accordingly called on talent from the world of Formula 1 to work on its new engines. Following the example set by Philippe Coblence, who worked on the Energy dCi 130 (type R9M), Jean-Philippe Mercier was tasked with engineering the Energy TCe 115.

Jean-Philippe Mercier (Powertrain Engineering Manager, Energy TCe 115 family):

“As early as the 1980s, we stood out as pioneers of downsizing in F1. Even in those days, we were getting some 850hp out of our 1,500cc turbocharged V6. The experience we have accumulated has brought us a thorough understanding of powerful engines for their size. My input has focused on the Energy TCe 115’s specific power, and the result is 100hp/litre, a first for a 1.2-litre engine. And Renault has no intention of stopping its work there!”

Me ha llamado la atención, que habrá un 0.9 tricilíndrico derivado del 1.2 y con 90 cv.

El 1.5 sigue con correa, pero mencionan una de larga vida. No ponen cuánta será esa vida.
