For those of you unfamiliar with the many processes that go on under the hood of your 2018 INFINITI Q50 while you’re driving it — well, you're not alone. Allow me to enlighten you on one of them, today. Featuring an advanced direct-injection gasoline system, this luxury sports sedan benefits from a cleaner and more efficient engine.
DIG is an innovative fuel-delivery technology that utilizes high pressures to remit a more exact amount of juice into the combustion cell — dependant on the throttle position and engine speed. In these DIG setups, the air and gasoline are not pre-mixed before entering the chamber. Rather, they are delivered separately — the air through the intake manifold and the gas directly into the cylinder.
Thanks to ultra-precise internal computer management, there is more accurate control of the metering. This accuracy equates to complete combustion and more bang for your buck out of every precious drop of gasoline. In fact, with this ingenuitive powertrain, the Q50 sees a 6.7% improvement in fuel economy over previous models. Rated to earn up to 23 MPG in the city and 30 MPG on the highway, those are numbers you could write home about.
