Direct injection is a term thrown around a lot by automakers these days, usually on their more premium or fuel-efficient models. It’s one of those technologies that automakers and consumers alike can really love. After all, direct injection technology can help boost horsepower while also reducing fuel consumption.
For anyone unfamiliar with the technology, it’s essentially a fuel injection system where the fuel entering the engine is highly pressurized and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port.
Fuel economy gains come from a number of factors, but mostly because of the precise control over the amount of fuel and injection timings, which can now be varied according to the load conditions.
Most major automakers are flocking to the technology, even branding it with names like EcoBoost from Ford or CGI from Mercedes-Benz.
The guys over at WindingRoad have now made it easier to find out which cars on sale in the U.S. have direct injection technology with a new list published in their latest issue. Check back regularly as this list is sure to expand quickly over the coming year as more automakers strive to meet tougher fuel economy standards around the globe.
