Title: Christopher North: Innovator in Fuel Injection Systems

Introduction

Christopher North is a notable inventor based in Camarillo, CA (US). He has made significant contributions to the field of fuel injection systems, holding 2 patents that showcase his innovative approach to engineering.

Latest Patents

His latest patents include advancements in valve controller systems and methods, as well as fuel injection systems. The fuel injection system he developed features one or more fuel injectors and an electronic control system. The preferred fuel injector utilizes a double magnetic latching solenoid three-way or four-way spool valve. This valve controls the flow of a working fluid, which is essential for managing the discharge of fuel into the combustion chamber or intake manifold of an engine. The control system is designed to provide actuating current pulses to each solenoid, effectively initiating and terminating the injection process.

The disclosed control systems offer a snap action in one or both actuating directions of the valve. This is achieved by electromagnetically retaining the valve in a latched condition until a high force builds in the actuated solenoid. Once this occurs, the valve is released for higher acceleration to the actuated position. Additionally, an exemplary control system is included that senses when the valve reaches the actuated position. This allows for the termination of the actuating current pulse as soon as possible, enabling a strong current pulse drive with low total energy for fast actuation of a relatively small valve.
