Still, the best way to keep your GDI engine running cleanly and properly is to practice proper maintenance. One example is a modification to the engine that allows it to spray a little fuel onto the valves themselves to act as a solvent and keep them clean. Some other automakers have tried some engineering fixes. They have also recommended owners occasionally add a fuel-system cleaner to their vehicle. Many of the automakers who have employed this technology have stepped up to the plate to try and fix it.īMW and Kia specifically have issued technical service bulletins to their dealerships urging them to recommend ethanol-free gasoline brands and gasoline with detergents. As anyone who has needed engine repair done can tell you, these are not cheap repairs.

The results can be drastic, with some drivers experiencing loss of power and engine stalling. Many people have complained to the National Highway Traffic Safety Administration that their GDI-powered cars experience high rates of fuel system clogging and engine carbon buildup. The main advantage of Gasoline Direct Injection technology, its precision, is also its main drawback. While the efficiency gains are without a doubt real, GDI technology creates a whole new set of problems.
This might all sound too good to be true. Some manufacturers suggest that GDI engines can achieve a 50% increase in low-end torque while also returning a 15% increase in fuel economy. The cooler temperatures allow for a better compression ratio, meaning greater efficiency and power with the same amount of fuel.
This direct injection results in a more complete combustion and cooler temperatures inside the cylinder. This is far more precise than older fuel-injection systems or carburetors. Gasoline direct injection engines work by injecting fuel at high pressure directly into the combustion chamber. What is Gasoline Direct Injection and how does it work? However, that added efficiency comes at a cost. Automakers are convinced–GDI works and it is efficient. Gasoline direct injection has crept into the mainstream and is now seen in more cars than ever. Cadillac was able to add 34 horsepower to its CTS without sacrificing fuel economy. When Consumer Reports tested its new Skyactiv engine, the gas mileage jumped from 28 mpg to 32 mpg. One example of GDI success is in the Mazda 3. GDI engines have produced some impressive results. It’s the latest fuel delivery technology and industry titans tout its better performance and better fuel economy. Gasoline Direct Injection (GDI) has been celebrated as a grand achievement by automakers.
