Learn about the challenges and solutions related to Gasoline Direct Injection (GDI) in engines. Issues, design flaws, and potential fixes.
How Do I Know if My Car Has GDI? Finding out if your car has GDI just by looking at the engine is a bit tricky because there’s nothing really visually obvious that’s unique to them.
One of the main problems with GDI engines is carbon build-up on the intake valves. This can cause a number of issues, including reduced horsepower, poor fuel economy, and engine knocking. Hyundai Santa Fe, Sorento, and Sportage models with GDI engines have been particularly prone to this problem.
Running a fuel system additive in your GDI engine is a no-brainer. Intake valves are not the only thing carbon has an effect on. Clogged injectors are a very frequent problem on GDI engines. Using a fuel system cleaner designed specially for direct injection engines will help to prevent carbon from plugging the injectors.
GDi engines aren't without their issues; fortunately for consumers, those issues are fairly well documented. The biggest and most egregious problem a GDI engine owner will run into is...
What are the challenges of GDI engines and how can they be overcome? One of the main challenges of GDI engines is the formation of deposits on the fuel injectors. These deposits can reduce the spray pattern and flow rate of the injectors, leading to poor combustion, increased emissions, reduced performance and potential engine damage.
Uncover the history, combustion, lubrication, and carbon issues of GDI engines, along with maintenance solutions for optimal performance.
No new technology is trouble free, and unfortunately GDi is no exception. Here we take a look at one of the most common service issues – carbon build-up – and how you can help your customers keep it under control.
Common Problems with GDI Engines. One of the biggest problems common in GDI engines is an unknowing owner using low-quality fuel. Since everything is running efficiently and cleanly in this type of engine, bad fuel introduces unwanted solids, such as Sulphur, iron, phosphorus, and many more, that don’t burn off cleanly.
This abnormal combustion event can result in higher engine pressures, leading to engine knock and potentially severe internal damage. As these service issues can occur in as little as 3,000 miles, diagnosing and remedying them early is important.
