  • Patent number: 9759142
    Abstract: An engine control system includes an engine calibration module that sets fuel injection timing based on one of N cetane number (CN) values, wherein N is an integer greater than one. A combustion noise module generates a combustion noise signal based on cylinder pressure in a compression ignition (CI) engine during combustion. A fuel quality determination module compares the combustion noise signal to N predetermined combustion noise levels corresponding to the N CN values, and that selects the one of the N CN values based on the comparison.

  • Publication number: 20120192956
    Abstract: A monitoring apparatus for monitoring the relative flow rates of first and second gases that are to be mixed comprises a first flow-monitoring, laminar flow element in a first gas flow path for detecting a differential first gas pressure thereacross and a second flow-monitoring, laminar flow element in a second gas flow path for detecting a differential second gas pressure thereacross. A comparator device compares the differential pressures and is operable to generate a response in dependence on said comparison.

  • Publication number: 20120180874
    Abstract: The present invention relates to an apparatus and method for maintaining a fluid mixing ratio. The apparatus according to various embodiments prevents a fluid flow imbalance between two proportionate fluid streams based on a pressure difference, and may be configured to alert the user and/or stop the fluid flow in the event of a fluid flow imbalance. The apparatus is formed such that two plunger components engage a shuttle piston, the shuttle piston configured to move one or more plunger components given a selectable fluid flow imbalance.

  • Publication number: 20120174989
    Abstract: A method of measuring characteristics of a critical orifice type constant flow rate instrument is applied to a dilution mechanism including dilution units in series. Diluent gas of one dilution unit and diluent gas of the other dilution unit are kept flowing in a derivation flow passage for deriving redundant gas of the corresponding one dilution unit in a manner that the total flow rate thereof is equal to a prescribed constant flow rate and that the flow rate of the diluent gas from the corresponding dilution unit is equal to the flow rate in use. The flow rate characteristics of the critical orifice type constant flow rate instrument are measured based on at least an upstream side pressure of the critical orifice type constant flow rate instrument provided in the derivation flow passage at this time.

  • Patent number: 8162068
    Abstract: A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.

  • Patent number: 8091575
    Abstract: A valve system for monitoring and controlling a flow of a fluid additive into a main fluid line is disclosed. The system includes a pump that provides a constant flow of the additive from a fluid reservoir through a supply conduit into the main fluid line. A portion of the fluid additive may be diverted into one or more return conduits leading back to the reservoir by opening a solenoid actuated valve in the return conduit. Flow meters are employed to detect the flow rates of the fluids in the supply conduit and the main fluid line. The flow meters provide signals to a control system, which are effective to control the operation of the solenoid actuated valves to maintain a desired flow of the additive into the main fluid line.

  • Publication number: 20110259437
    Abstract: The invention relates to a thermostatic mixing valve comprising a hollow body having a first inlet, a second inlet, and an outlet in fluid communication with the first inlet and/or the second inlet via a mixing chamber. The flow through the valve is controlled by an axially extending thermostatic actuator comprising a stem, an enlarged portion and a heat sensitive bulb, said bulb extending into the mixing chamber. The thermostatic actuator is axially displaced between a first end position in which only the first inlet is connected to the outlet and a second end position in which only the second inlet is connected to the outlet. The thermostatic actuator is displaced in a sleeve member arranged to restrict the flow of water from the second inlet past the enlarged portion of the thermostatic actuator during its axial displacement until the thermostatic actuator reaches the second end position.
