Understanding Gasoline Direct Injection

Be sure to recommend quality GDI components that are rigorously tested and manufactured to precise standards.

Published: June 6, 2022

GDI stands for gasoline direction injection, a fuel-delivery technology that improves combustion by spraying fuel directly into the cylinders where it can mix with air.

GDI first appeared in the U.S. market on a limited basis in the 2007 model year, and it’s been growing fast. According to data compiled by the Environmental Protection Agency, GDI engines were installed in 57 percent of model-year 2020 vehicles, up from a mere 2.3 percent in 2008.

So why would the EPA be interested in GDI technology? Well, the simple answer is that GDI allows for better control of the combustion process, which improves fuel economy and engine performance and lowers emissions.

Have you ever wondered in a rear-wheel-drive vehicle how the engine spinning in the center of the car can spin the wheels that are perpendicular to the engine?

Well it is a mystery how that happens. Additionally in that same space we change the ratios of revolutions and the torque available to spin everything.
