This new 1.6 litre HDi FAP diesel engine has been designed to meet the requirements of the new Euro 5 emission standards. It also benefits from a number of improvements over the current 110 bhp unit with improved performance in terms of flexibility and responsiveness, as well as noise reduction, while at the same time reducing fuel consumption and CO2 emissions.
Thanks to its new hi-tech design, this new four cylinder engine with a capacity of 1,560 cm3, and eight valves, has a maximum torque output of 270 Nm at 1,750 rpm, an increase of 12.5% over the current engine, and during overboost, 285 compared to 260 Nm. It also has a very wide operating range with high levels of torque available at all times, ensuring good driveability and reduced fuel consumption on a day to day basis (since the user can drive more often at lower engine speeds): 135 Nm from 1000 rpm, 242 at 1500 rpm, 270 from 1750 to 2000 and 224 Nm at 3500 rpm. Its maximum power output is 112 bhp at 3600 rpm.
This technology is combined with a new common rail injection system (Continental Automotive System) where the injection pressure is increased to 1,650 bars (compared to1600 previously) as well as new piezo-electric injectors with seven apertures (instead of solenoid injectors with six apertures as fitted to the previous 1.6 litre HDi diesel engine).
The engine management software has also been entirely redesigned to give this unit more comprehensive injection mapping (up to 5 injections per cycle), improved efficiency and better diagnostics for after-sales service. This helps to improve the homogeneity of the air/diesel fuel mixture for maximum performance, reduced fuel consumption, a reduction of emissions at source and quieter combustion.
The engine also uses a Honeywell Turbo Technology variable-geometry turbocharger optimised in terms of its size. Being smaller, it has a lower inertia, reducing response times to a minimum. An improved exhaust gas recirculation system (EGR valve) and the reduction of internal friction losses allows maximum enhancement of engine efficiency while minimising potential energy losses. Like its predecessor, this 1.6 litre HDi comes as standard with a diesel particulate emission filter (FAP) with a service life of 112,000 miles.
This new engine will be available in the 308 CC in both Sport and SE trim levels and will be known as the HDi 112.Peugeot introduces 308 CC
