  • Patent number: 9777610
    Abstract: A flow manifold system for injecting a first gas into a second gas, such as, for example, a system for injecting ammonia gas into the exhaust gas of an internal combustion engine. The first gas may be supplied to the system by one or more cartridges. The system may also include a control valve that is configured to control the delivery of the first gas to the least one critical flow orifice. The critical flow orifice is configured to allow for a relatively constant volumetric flow of the first gas through the critical flow orifice when the first gas attains a critical flow. Such critical flow may allow for an accurate estimation of the flow of the first gas through the critical orifice, and subsequently to the second gas, without the use of a flow sensor.

  • Patent number: 9709012
    Abstract: A method and apparatus for determining a characteristic of an injector are set forth. In one example, a compressed gas is applied to the inlet chamber of the injector while the spoolvalve is closed until the pressure of the compressed gas in the inlet chamber reaches a predetermined pressure. A change in pressure of the compressed gas in the inlet chamber is measured over time while the spool valve is closed. The pressure change measurement corresponds to the characteristic of the injector that is to be determined.

  • Patent number: 9670851
    Abstract: A control system for an internal combustion engine comprises pressure sensing means, memory means, processing means, and fuel injection control means. Pressure sensing means generate in-cylinder pressure data used to calculate total heat generated during combustion cycle. Memory means store predetermined crank angle data, such as CA50 crank angle data, for variety of engine operating conditions. A CA50 crank angle is a crank angle position where fifty percent of total heat is generated. Memory means additionally stores allowable start of injection crank angle data. Processing means determine an observed CA50 crank angle. Processing means conducts comparison of at least one of the predetermined CA50 crank angle data against the observed CA50 crank angle to generate a start of fuel injection crank angle which impacts the observed CA50 crank angle during subsequent combustion cycle. Fuel injection control means controls start of fuel injection crank angle generated by the processing means.

  • Patent number: 9651013
    Abstract: An apparatus for setting a clearance has a movable body and a valve guide. A valve body is disposed along the axis of the movable body, and a bore hole is formed in the movable body. The bore hole is formed on the axis and includes a first bore with a first diameter, a receiving surface, and a second bore. A tool having a forward surface is inserted into the bore hole and pressed against the receiving surface. The flow of a fluid between the guide cylinder and the movable body is determined and compared against a standard.

  • Patent number: 9638128
    Abstract: A compression ignition engine (10) operates to fuel an engine cylinder (12) to create an in-cylinder air-fuel charge and to cause that charge to autoignite. A fuel injector (20) operates to inject fuel into the engine cylinder for substantially the entire duration of a first phase (24) of fuel injection at substantially the maximum injection pressure that the fuel injector can deliver to create a premixed fraction of the in-cylinder air-fuel charge prior to autoignition. As the first phase ends, fuel injection transitions to a second phase (26) which commences in advance of autoignition. During the second phase, the fuel injector injects fuel into the engine cylinder at a rate of injection that is significantly less than the rate of injection used during the first phase.

  • Patent number: 9605611
    Abstract: Injector drift for a diesel engine are detected by reconfiguration of injection patterns from one pattern into a pattern with a different number of pulse points while attempting to hold total fuel injected constant. If a particular injector is subject to drift then changes in the pulse pattern result in an increase or decrease in fuel injected and consequential variations in engine speed. By applying alternating injection patterns at constant fuel demand and allowing engine speed time to stabilize, a rhythmic variation in engine speed/torque will appear which can be detected using one of a number of techniques.

  • Patent number: 9599042
    Abstract: A method for controlling fuel injection timing into a cylinder of an internal combustion engine having an internal control system based on ignition delay correlation wherein intake manifold pressure and oxygen concentration values are compared to steady state values of manifold pressure and oxygen concentration of a particular indicated torque set-point and engine speed. Comparing intake manifold pressure and oxygen concentration to steady state reference values further comprises experimentally determining exponential factors for intake manifold pressure factor and oxygen concentration factors. A multiplier for intake manifold pressure and oxygen concentration is determined taking into consideration the exponential factors for manifold pressure and oxygen concentration. An equation for correlation ignition delay is used to determine optional SOI timing.

  • Patent number: 9587590
    Abstract: An engine control system coordinates control of a pressure regulating mechanism associated with a turbocharger turbine and control of a variable valve actuating (VVA) mechanism for expanding the range of possible exhaust gas recirculation rates over a large portion of an engine operating map to provide EGR rates which are greater than typical present-day levels while mitigating engine pumping losses by causing the turbocharger to operate with better efficiency in some regions of the map where it otherwise would not. Turbocharger efficiency is improved by controlling the VVA mechanism to set the timing of operation of its respective cylinder valves in accordance with a predetermined correlation of operating efficiencies of a compressor to timing of operation of respective engine cylinder valves, causing the compressor to operate at points of better efficiency than it otherwise would without use of VVA.

  • Patent number: 9562491
    Abstract: A device and method for preventing and removing carbon deposit build-up on a piston/cylinder assembly of an engine, including a diesel engine, is disclosed. The device includes a cylinder having an inner sleeve for receiving a piston, a carbon scraping ring positioned on the cylinder sleeve, the carbon scraping ring including an inner surface, and an abradable coating applied to the inner surface of the carbon scraping ring providing a wearable surface between the piston and the cylinder sleeve. The abradable coating has a wearable surface, which conforms to the shape created by the movement of the piston and the cylinder sleeve and carbon scraping ring, creating a substantially zero clearance fit between the piston and the carbon scraping ring. The clearance may reduce oil consumption and improve sealing of the cylinder and piston, thereby reducing blow-by.

  • Publication number: 20160356192
    Abstract: Systems and methods for tracking and indicating a status for the deliverable reductant, such as ammonia, in a canister used in an exhaust gas after-treatment system are disclosed. An on-board system provides a visual display to indicate either generally or specifically the fill-status of each of a plurality of loaded ammonia canisters, while a separate canister system is able to be periodically updated while on-line and, using a memory device such as a RFID tag, carry the updated fill-status even when it is removed from the vehicle system. The residing memory device can be read off-line to determine the ammonia fill-status. Metering of the ammonia flow allows real-time monitoring and updating of the canister status.
