Abstract: A leak detection device includes a body having at least one fluid input that receives a fluid leak, at least one drain fluidly coupled with a container, and at least one sensor conduit input fluidly coupled with at least one sensor. The fluid input is located above the drain but below the sensor conduit input. The body includes an internal conduit that is fluidly coupled with and extends between the fluid input, the drain, and the sensor conduit input. The internal conduit includes a lower branch that extends below the fluid input to the drain. The internal conduit includes an upper branch that separately extends in the body above the sensor conduit input to the drain. The lower branch includes a reduced flow portion below the fluid input and the sensor conduit input but above the drain.

Abstract: A configuration is provided for a fuel injector for a common rail fuel system. In one example, the fuel injector may include a housing, an inner chamber enclosed by the housing, and a flow limiting valve. The flow limiting valve may be arranged at a downstream end of the inner chamber and also enclosed by the housing. This configuration may allow the fuel injector housing to have sufficient wall strength to withstand high pressure fuel injection and may allow effective fuel supply cut off when fuel cut off is demanded.

Abstract: Various methods and systems are provided for indexing an injector map and subsequently controlling fuel injection to an engine. In one embodiment, a method for the engine includes injecting fuel via activating an injector for a determined activation time, the activation time determined based on a commanded fuel value and a function of a modified pressure difference across an orifice of a nozzle of the injector, where the modified pressure difference is based on a difference between a rail pressure and peak cylinder pressure, the peak cylinder pressure scaled by a function of engine speed and injection timing and the pressure difference offset by a correction factor.
