Due to future exhaust gas emission legislations, vehicle manufacturers need to implement additional emissions reductions. Based on three factors – market development, legislation and end customers – Bosch has developed a new generation of gasoline direct-injection systems. According to the engineers, approximately 80 % lower PN emissions can be achieved under RDE conditions.

Requirements on New Gasoline DI Systems

Today, gasoline engines are the preferred solution for passenger car powertrains due to favourable unit costs, high power density, potential for low exhaust gas emissions and high robustness against worldwide fuels. Compared to 70 million gasoline engine cars in 2015, 78 million gasoline engine powered vehicles are forecasted for 2025, Figure 1. While gasoline engine volumes with port fuel injection (PFI) are expected to decline, gasoline DI engines are predicted to double during this time frame. Consequently, an estimated 39 million PFI engines as well as 39 million DI...
