Introduction

Richard J Lill is an accomplished inventor based in Naperville, IL, with a notable portfolio of three patents. His work primarily focuses on advancements in fuel injection systems, contributing significantly to the automotive industry. Lill's innovative designs aim to enhance engine performance and reduce emissions, showcasing his commitment to sustainable technology.

Latest Patents

One of Lill's latest patents is a hybrid fuel injection system. This system allows for electronic control over the injection processes, enabling selective rate shaping and multiple injections. The hybrid fuel injection system features an add-on common rail system (CRS) that provides supplemental fuel injections alongside the main fuel injections from a unit pump system (UPS). Additionally, the CRS can facilitate a 'limp-home' mode of engine operation in case of UPS failure. Both systems utilize a common fuel supply, return, injector, and electronic controller.

Another significant patent involves electronically-controlled late cycle air injection. This system aims to achieve simultaneous reduction of NOx and particulate emissions from diesel engines. It is implemented in three different embodiments for each cylinder. The first embodiment includes a T-adapter, an air solenoid, a fuel injector, and a control unit. The T-adapter receives pressurized fuel and air, which are then directed to the fuel injector. The air solenoid regulates the air flow to the injector via the control unit. The second embodiment features a modified fuel injector with an air passage and a communicating sac that connects to the fuel valve. Compressed air is supplied through an air solenoid to this passage. The third embodiment incorporates a modified cylinder head, where compressed air is supplied to combustion chamber cylinder ports.
