BMW 330i engine explained in detail
The latest version of the BMW 3 Series has arrived in Malaysia and we have decided to look a little deeper into its only engine variant (for now).
The engine in the new BMW 330i Sedangenerates more spirited performance than ever. Boasting numerous detailupgrades, this two-litre, four-cylinder unit delivers maximum output of 190kW/258 hp between 5,000 and 6,500 rpm, while peak torque of 400 Nm (295 lb-ft)is available from 1,550 to 4,400 rpm. The 5 kW/6 hp increase in output and theextra 50 Nm (37 lb-ft) of torque compared with the predecessor engine are theresult of the focused optimisation of the BMW TwinPower Turbo system – whichcomprises twin-scroll turbochargers, High Precision Injection direct petrolinjection, VALVETRONIC fully variable valve timing and Double-VANOS variablecamshaft timing.
The High Precision Injection system ensuresprecise fuel metering and particularly clean combustion, its new fuel pumpgenerating maximum pressure of 350 bar compared with the 200 bar of theprevious version.
The further developed direct injectionsystem enables optimal fuel flow through the combustion chambers with atomisedfuel delivered by multi-hole injectors. Other characteristics of this engineinclude a lighter crankshaft, reduced internal friction, optimised heatmanagement and a new digital engine management system.
An impressive 0 to 100 km/h (62 mph) timeof 5.8 seconds belies the enhanced efficiency of the new BMW 330i Sedan withits combined fuel consumption of 6.1 – 5.8 l/100 km (46.3 – 48.7 mpg imp) andCO2 figures between 139 und 132 grams per kilometre.
The engine’s emissions have also been further improved. The exhaust treatment system includes a particulate filter to reduce emissions of particulate matter. As a result, the new BMW 330i Sedan complies with the particularly demanding Euro 6d-TEMP emissions standard.
