Bosch’s GDI Service Solution for the Automotive Aftermarket

Direct injection gasoline engines are a growing market, with an estimated four million vehicles on the road by 2019. That number is expected to double in the next few years. In order to meet the needs of these customers, Bosch offers a complete GDI service solution for the automotive aftermarket. This solution includes advanced components originally developed for the world’s most competitive racing teams, state-of-the-art diagnostic solutions, and industry benchmark training. All Bosch GDI components are designed to deliver unmatched quality and reliability.

Despite the benefits, modern GDI systems are not without their drawbacks. GDI systems can lose their efficiency over time because of deposits that form on valves, intake ports, and piston surfaces. These deposits are caused by a constant struggle to meet the needs of the environment while also providing fuel efficiency.

The fuel injectors in a GDI system require a voltage of 65 volts on both channels to operate. To measure this, a low inductive current probe is clamped around the injector control wire. Amperage values vary from eight to twelve amps, with the peak current in a GM GDI system reaching 12 amps. The injector’s resistance is in the range of 1.5 ohms.

GDI systems are now common in more cars and trucks. These systems were designed to reduce fuel consumption, improve economy, and save on engine size. While the systems are more complex, they do have some advantages. For example, modern GDI systems include a high-pressure pump and a low-pressure circuit. The high-pressure pump compresses gasoline to a pressure of 200 bar, allowing a precisely mixed fuel to enter the combustion chamber.

Modern GDI systems are highly accurate, which improves the efficiency of fuel atomization. They can also improve combustion efficiency and reduce tailpipe emissions. The benefits of GDI fuel injection are numerous. Today’s ECUs are able to accurately meter the amount of fuel being injected, which translates to better mileage and lower emissions.

Fuel injection process optimization is also a key part of modern GDI systems. This is vital to ensure efficient combustion, reducing fuel consumption and pollutant emissions. Another important feature of GDI systems is high injection pressure. The increased pressure increases the fuel atomization and improves spray evaporation. This in turn leads to improved mixture formation.

Despite the benefits, modern GDI systems come with their own problems. The most common drawback is precision. Some cars with GDI fuel injection have suffered engine carbon buildup, which leads to loss of power and engine stalling. Moreover, these problems can be costly to repair.
