Title: Yiping Chen: Fuel Delivery System Diagnostics

Introduction

Yiping Chen is an inventor associated with Jiangsu, China, and Robert Bosch. His work includes a patent concerning a method and device for diagnosing a fuel delivery system in an internal combustion engine.

Latest Patents

Chen’s listed patent, “Method and Device for Diagnosing a Fuel Delivery System,” describes a procedure for testing an electrically activated controllable valve positioned at the inlet of a high-pressure fuel pump. The pump supplies fuel to a pressurized fuel store, which is connected to at least one injector and includes a pressure controller.

The method increases the pump’s rotational speed and operates the valve until the fuel-store pressure reaches a specified low level. It then changes the valve’s current supply to open the valve further while maximizing injection, continuing until the pressure reaches a threshold. After returning the pressure to the low level, the method determines a further quantity based on that low-pressure level and the maximum pressure reached. Chen is listed as having 1 patent.

Career Highlights

The available information associates Chen with Robert Bosch and identifies his patent work in fuel-system diagnostics. The described approach uses pressure behavior during controlled valve and injector operation to assess the fuel delivery system.

Collaborations

Patrick Weiss is identified as Chen’s coworker. The available information does not specify their roles or describe a particular joint project.

Conclusion

Yiping Chen’s listed patent focuses on diagnosing fuel delivery systems through controlled testing of a high-pressure pump, valve, and injectors.
