Publication number: 20070144462Abstract: The present invention removes voltage that accumulates over a period of time in an automotive engine cooling system. This accumulation of voltage is provided a path to travel inside the engine and cooling system by the cooling liquid used to cool the vehicles engine. This accumulation of voltage looks for a likable metal to bond with and the constant colliding of the voltage trying to bond with the metal creates damage know as electrolytic metal erosion. Overtime this act of nature erodes and weakens metal cooling system components causing them to fail. This process can lead to the vehicle breaking down due to its engine overheating. The electronic voltage remover is designed to remove and dissipate this harmful voltage from the vehicle's engine cooling system.Type: ApplicationFiled: December 27, 2005Publication date: June 28, 2007Inventor: Michael Green

Publication number: 20070144495Abstract: A fuel tank assembly includes a fuel tank having a plurality of side walls spaced apart by a floor. A flange extends downward from one of the plurality of side walls at an angle toward the floor. A fuel pump extends from the flange; the fuel pump and flange are arranged to fixedly position at least one inlet connected to the fuel pump at or in close proximity to the floor of the fuel tank. A fuel dam extends away from the floor and has at least one passage formed therein. The fuel dam is positioned so as to create an accumulated area of the fuel tank surrounding the at least one inlet. Fuel enters the accumulated area through the at least one passage and is received by the at least one inlet.Type: ApplicationFiled: December 22, 2005Publication date: June 28, 2007Inventors: Michael Teets, Trevor Enge, Robert Schmidt, Lavern Bremmer

Publication number: 20070144496Abstract: A canister assembly is mounted between a fuel tank and an internal combustion engine. The canister assembly includes a canister holding a carbon charge for adsorbing fuel vapors emanating from the fuel tank. A trap box defines a plenum and is mounted on the canister and a canister pipe stub permits the plenum to communicate with the carbon charge. The trap box has a load port disposed thereon and the load port is connectable to the fuel tank for passing a flow of fuel vapors from the tank into the plenum with the fuel vapors becoming adsorbed by the carbon charge as the vapors flow from the plenum and through the canister pipe stub and into the carbon charge in response to an overpressure in the fuel tank. The canister pipe stub is arranged in the plenum so as to permit any liquid fuel accompanying the vapor flow to become trapped in the plenum thereby preventing the liquid fuel from reaching the carbon charge and causing the latter to become degraded thereby.Type: ApplicationFiled: December 23, 2005Publication date: June 28, 2007Inventor: Daniel Bellmore

Publication number: 20070144502Abstract: An EGR failure determination system for an internal combustion engine, which is capable of accurately determining failures of both an external EGR device and an internal EGR device, irrespective of whether the EGR amount is large or small, thereby making it possible to enhance marketability of the system. The EGR failure determination system includes an ECU. The ECU calculates an actual fresh air ratio, and sets a target value thereof. Further, it calculates a feedback correction coefficient according to the actual fresh air ratio and the target value, and controls an exhaust recirculation mechanism and three variable mechanism. When the feedback correction coefficient is not within a predetermined range, and if it is larger than 0.5, at least one of the three variable mechanism is determined to be faulty, whereas if it is not larger than 0.5, the exhaust recirculation mechanism is determined to be faulty.Type: ApplicationFiled: September 26, 2006Publication date: June 28, 2007Inventors: Ken Ogawa, Toru Kitamura
