Abstract: A fuel injector for an internal combustion engine is disclosed. The fuel injector includes a tip in fluid connection with a combustion chamber of the engine and includes an orifice for injecting fuel as a fuel jet. The fuel injector includes a protruding member in fluid connection with the first orifice extending from the tip at a protruding angle. The orifice injects the fuel jet into the first protruding member. The fuel injector includes a plurality of extension members in fluid connection with the protruding member and includes at least, a first extension member and a second extension member. The first and second extension members may extend from the protruding member at extension angles. The fuel jet may be distributed into, at least, a first distributed jet and a second distributed jet when the first fuel jet flows from the protruding member to the first plurality of extension members.

Abstract: A ducted combustion system is disclosed. The ducted combustion system includes a combustion chamber bound by a flame deck surface of a cylinder head of an internal combustion engine and by a piston top surface of a piston disposed within the internal combustion engine. The system includes a fuel injector including one or more orifices, the one or more orifices injecting fuel into the combustion chamber as one or more fuel jets. The system includes one or more ducts disposed within the combustion chamber between the flame deck surface and the piston top surface, the one or more ducts being generally tubular shaped structures and being disposed such that each of the one or more fuel jets at least partially enters one of the one or more ducts upon being injected into the combustion chamber.

Abstract: A reactivity controlled compression ignition engine compression ignites a stratified reactivity charge mixture, of recirculated exhaust gas, air, a low reactivity fuel and a high reactivity fuel. During steady state operating conditions, combustion phasing control includes adjusting an exhaust gas recirculation (EGR) rate relative to a base EGR rate associated with the steady speed and load. When transitioning to a new speed and load during a transient condition, combustion phasing control does not utilize EGR rate control, but does include adjustments to quantities and timings of at least three injection sequences of the high reactivity fuel.

Abstract: A sports training aid is provided that includes a base, a support structure and a top portion. The base structure may support the support structure and the top portion in an upright position when placed on a surface. The top portion includes a first side and a second side with extensions extending towards a user. A waist boundary is formed in between the extensions. Therefore, a user may position their waist within the extensions and practice a swing. The extensions of the sports training device may provide proper restriction and thereby train a user to have a proper hip rotation.

Abstract: The present invention provides a securing device for securing the sewer drain line of a recreational vehicle during use. The securing device comprises a hold-down member that passes over the top of the sewer drain line and has opposing ends secured to the ground.
