Abstract: A fuel injection apparatus for an internal combustion engine includes a fuel supply line in communication with a fuel tank and a fuel pump system. A fuel rail is connected to the fuel supply system and a plurality of fuel injectors. A return line extending from the fuel rail to the fuel tank. A by-pass passage extending from the supply line to the return line and including a pressure release valve having a pre-set activation pressure. A fuel temperature sensor for sensing a feed temperature of the fuel in the fuel supply system. A pressure control module that sets a first pressure set point in the fuel rail below the pre-set activation pressure when the feed temperature is below a predetermined temperature and sets a second pressure set point above the pre-set activation pressure of the pressure release valve when the feed temperature is above the predetermined temperature.

Abstract: A system for minimizing hydrocarbon vapor emissions includes a fuel vapor adsorption canister and a fresh air vent line from the fuel adsorption canister to an ambient environment to vent the fuel vapor adsorption canister. The fresh air vent line includes one or more hydrocarbon trap sections. The one or more hydrocarbon trap sections of the fresh air vent line adsorb hydrocarbon emissions from the fuel vapor adsorption canister to minimize hydrocarbon emissions to the ambient environment.

Abstract: Methods and apparatus are provided for electrostatic discharge mitigation for a fuel module. In one embodiment, the system includes a fuel pump having a power and ground connection for pumping fuel. A fuel filter in fluid communication with the fuel pump, the fuel filter including one or more components made of a non-conductive plastic and having a sulfonated surface covered with a conductive surface formed over the sulfonated surface. The conductive surface is electrically coupled to the vehicle ground plane. A method is provided for mitigation of electrostatic discharge in a fuel module. In one embodiment, the method includes sulfonating non-conductive plastic components of the fuel module to provide a sulfonated layer on the non-conductive plastic components and forming a conductive layer over the sulfonated layer to provide an electrical discharge path for electrostatic buildup resulting from fuel moving through the fuel module.
