20200132027 | SNORKEL SYSTEM - A snorkel system comprising: (a) a vehicle adapter configured to connect to a vehicle; (b) one or more air tubes configured to extend along an interior of an engine compartment of the vehicle; and (c) one or more angle adapters adapted to be located within the engine compartment of the vehicle, the one or more angle adapters fluidly connecting the vehicle adapter and the one or more air tubes together; wherein the one or more angle adapters include: an inlet opening located within a first plane, the inlet opening being located proximate to and in fluid communication with the vehicle adapter, and an outlet opening being in communication with a first end of the one or more air tubes, the outlet opening being located within a second plane that is spaced apart from and extends substantially parallel to the first angle adapter. | 2020-04-30 |
20200132028 | VALVE DRIVE FOR AT LEAST ONE POPPET VALVE OF AN INTERNAL COMBUSTION ENGINE - The present disclosure relates to a valve drive for at least one poppet valve of an internal combustion engine. The present disclosure further relates to an internal combustion engine and a motor vehicle having such a valve drive. The valve drive includes a valve lever for actuating the at least one poppet valve; and a valve lever axle on which the valve lever is mounted in a pivotably movable manner. The valve drive is characterized in that a fuel distributor for receiving pressurized fuel, that is to say, a rail, is integrated in the valve lever axle. | 2020-04-30 |
20200132029 | High-Pressure Fuel Pump - Provided is a high-pressure fuel pump that ensures oil tightness even at high fuel pressure and has a small and lightweight inexpensive discharge valve structure. Therefore, a high-pressure fuel pump according to the present invention includes: a discharge valve arranged on a discharge side of a pressurizing chamber; a discharge valve seat on which the discharge valve is seated; and a facing member configured independently as a separate member from the discharge valve seat and located on an opposite side of the discharge valve seat with the discharge valve interposed therebetween, in which a stroke direction regulating portion that regulates displacement of the discharge valve in a stroke direction is formed on a tapered surface of the facing member. | 2020-04-30 |
20200132030 | FILTER ASSEMBLY FOR FUEL INJECTORS - A filter assembly for filtering hydraulic fluid in a hydraulically actuated fuel injector is disclosed. The filter assembly includes a plurality of first rollers and a plurality of second rollers. The first rollers are parallelly disposed one after the other, and define first axes disposed in a first plane. The second rollers are parallelly disposed one after the other, and define second axes disposed in a second plane. The first plane is parallel to the second plane. Further, each second roller is disposed between a consecutively arranged pair of first rollers to define one or more filtration zones for filtering the hydraulic fluid. | 2020-04-30 |
20200132031 | Electronic Carburetor Injection - An electronic carburetor injection system is provided for an internal combustion engine. The electronic carburetor injection system is a standalone, user programmable fuel injection system that delivers additional fuel to the engine whenever a lean fuel/air mixture is delivered by a carburetor. The electronic carburetor injection system includes a fuel injector that delivers liquid fuel in the form of a spray discharge. A plate supports the fuel injector between the carburetor and an intake manifold of the engine. The plate includes an injector port that allows the spray discharge to enter the intake manifold without interfering with operating the carburetor. An engine control unit operates the fuel injector according to signals received from an oxygen sensor that is disposed within an exhaust system of the engine. During operation, the electronic carburetor injection system maintains the fuel/air mixture within a proper range across multiple driving conditions and changing environmental conditions. | 2020-04-30 |
