Turbocharger architecture: - 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.
The new Energy dCi 90 engine is simply the best! With a combined fuel consumption 88.3 mpg and CO2 emissions of 83 g/km* (reduced emission version) the New Clio offers a very economical driving experience to both private and business users.
ECO MODE To reduce fuel consumption even further, the driver can select ECO Mode, which modifies the vehicle's acceleration, torque / power management and heating / air-conditioning.
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.
