The high performance 500bar fuel system is designed to significantly reduce exhaust particulate emissions, while fuel economy improvements can also be measured.

• The complete system delivers excellent value to customers by adjusting the engine design without significant cost increases and reducing reliance on the expensive exhaust after-treatment system.
• Sold under PHINIA’s globally recognized Delphi brand.
• PHINIA Inc., a leader in premium fuel systems, electrical systems and aftermarket parts, announced that, in a global first, it will provide its high-performance 500bar Gasoline Direct injection (GDi) fuel system to Changan Auto, a renowned Chinese automotive manufacturer.

The advanced system, developed by PHINIA, and sold in the market under the globally recognized Delphi brand, can significantly reduce particulate emissions and lower fuel consumption without requiring an expensive redesign of the engine. The first-of-its-kind 500bar fuel system will make its global debut as part of a Changan Auto hybrid vehicle launch set to take place in Q2.

Yang Hongyong, General Manager of PHINIA Fuel Systems China, said that: "This is our first global mass-produced 500bar project. We are delighted to cooperate with Changan Auto, a leading player in the Chinese automobile market. Our high-pressure 500bar GDi fuel system provides customers with a cost-effective solution, which improves vehicle fuel economy and is designed with emissions reduction in mind. Together, we will champion the development of hybrid vehicles in China.”

This innovative 500bar GDi fuel system boasts several key advancements designed to optimize engine performance and minimize emissions. An enhanced pressure vessel and improved fuel rail interface ensure consistent high-pressure fuel delivery. Moreover, a significant increase in electromagnetic force empowers injectors for more precise fuel metering and more stringent closed-loop control.

These combined improvements translate to real-world benefits. The improved fuel system delivers better engine efficiency, particularly during the crucial warm up phase before the catalytic converter activates. Owing to a simplified after-treatment system, this can lead to

reduced reliance on current bulky and expensive after-treatment systems, delivering financial and environmental upside for Changan. Additionally, the system’s adaptability to various fuel types and different engine platforms ensures broad applicability without any major engine design modifications.

It is expected that Changan Auto's hybrid vehicles equipped with the 500bar GDi fuel system will be launched to the market in Q2 2024.
