The increasing demand for fuel-efficient vehicles is driving the growth of the market as GDI systems offer significant improvements in fuel economy compared to traditional port fuel injection systems. This is because GDI injects fuel directly into the combustion chamber, allowing for a more precise air-fuel mixture and more efficient burning of gasoline. According to the Society of Automotive Engineers (SAE), GDI technology can improve fuel economy by up to 15%. Additionally, another factor propelling the GDI market is stricter government regulations on emissions. GDI systems can also help to reduce harmful emissions like nitrogen oxides (NOx) and particulate matter (PM). These targets are pushing automakers to adopt fuel-efficient technologies like GDI to meet the regulations.
 

Furthermore, the growing popularity of SUVs and MPVs is also contributing to GDI market growth. These larger vehicles often require more powerful engines, and GDI systems can help to deliver the necessary power while still maintaining good fuel economy. The Global Alliance of Automobile Manufacturers (OICA) predicts that SUV sales will continue to rise in the coming years, further fueling demand for GDI technology.
 

One of the challenges in the market is the potential for increased carbon deposits on the intake valves. GDI injects fuel directly into the cylinder, bypassing the intake valves where it would normally help clean them. This can lead to a buildup of carbon deposits over time, which can reduce engine performance and fuel efficiency. Manufacturers can tackle this situation by developing injectors with features that help to minimize valve deposits. For example, using multiple spray holes or a special spray pattern can distribute fuel more evenly and reduce the concentration on areas prone to buildup. Also, developing new valve materials that are more resistant to carbon buildup is another potential solution.
