  • Patent number: 10961971
    Abstract: The present disclosure provides a system for reducing cold start emissions of a motor vehicle. A brushless DC motor is coupled to an engine for cranking the engine. In response to receiving a cold start signal from a cold start actuator, the motor controller activates the brushless DC motor to crank the engine for a cold start duration and increase fuel pressure. In response to a motor controller receiving an auto start signal from an auto start actuator, the motor controller activates the brushless DC motor to crank the engine for an auto start duration that is shorter than the cold start duration. In response to determining that the cold start duration or the auto start duration has expired, an engine controller activates the fuel delivery system to deliver fuel to the engine.

  • Patent number: 10724419
    Abstract: A method to determine soot mass of a gasoline engine powered automobile vehicle includes: predefining a time period between approximately 50 seconds to 200 seconds defining a cold start operation of a gasoline engine; determining a critical engine cold start temperature at a time defining a start of the cold start operation; identifying a cold start soot mass value from a lookup table based on the predefined time period and the critical engine cold start temperature; calculating a hot engine soot mass value for a hot engine operating time; repeating the calculating step for at least one next successive hot engine operating time; and adding the cold start soot mass value to the hot engine soot mass value for the hot engine operating time and the at least one next successive hot engine operating time to define a total soot mass value.

  • Patent number: 9797358
    Abstract: A system according to the principles of the present disclosure includes a fuel injector cleaning module and a fuel control module. The fuel injector cleaning module generates an instruction to clean a fuel injector of an engine based on engine operating conditions. The fuel control module, in response to the injector clean instruction, controls the fuel injector to perform N fuel injections for each combustion event in a cylinder of the engine and, during each of the N fuel injections, deactivates the fuel injector before the fuel injector fully opens. N is an integer greater than one.

  • Patent number: 9109518
    Abstract: An internal combustion engine is equipped with an EGR system that includes an EGR heat exchanger. A method for monitoring the EGR heat exchanger includes monitoring an EGR gas inlet temperature to the EGR heat exchanger, an EGR gas outlet temperature from the EGR heat exchanger, a coolant temperature and a mass EGR flowrate through the EGR heat exchanger for a present engine operating point. An actual thermal effectiveness of the EGR heat exchanger for the present engine operating point is determined. A maximum heat transfer coefficient for the EGR side of the EGR heat exchanger is determined for the present engine operating point. The EGR heat exchanger is regenerated when the actual heat transfer coefficient differs from the maximum heat transfer coefficient for the present engine operating point.

  • Publication number: 20100242470
    Abstract: Simultaneous or independent control of a by-pass valve and a variable-geometry forced induction component on a combustion engine is based on operational parameters measured by various sensors provided as inputs to a control module. Sudden loss of power due to low turbine efficiencies is prevented during transitions between operating conditions of engine speed and load. Excessive peak cylinder pressures are also prevented by controlling engine boost pressure to a permitted limit at high engine speed and load.

  • Patent number: 7760483
    Abstract: A lightning protection method and device with compound actively generated plasma and passively produced plasma provide lightning protection without the need for grounding of the protected object. The device has lightning rods with a plasma piping inside. The high density plasma generated by an active plasma generator is blown through the piping, spread out at the tips of the rods and compounded with the plasma passively produced by the corona discharge on the tips under the action of lightning cloud electric field. The compound plasma dissipates the electric charges, on the tips of the rods, inducted by the lightning cloud electric field, and neutralizes the electric charges of the lightning, preventing a thunderstruck to a protected object related to the rods.

  • Publication number: 20100078426
    Abstract: A system for keeping a solution of urea in a liquid state comprising a tank having a level sensing apparatus, inlet and outlet tubes for supplying and withdrawing urea solution, and a plurality of non-contact heating elements disposed in vertical relationship to one another. Preferably, the heating elements are infrared (IR) radiative coils encased in IR-transparent quartz tubes. In one embodiment, each heating element represents a horizontally defined heating zone. When the reservoir tank is full and predetermined temperature conditions are met, all of the heaters are on, each heater irradiating its own horizontal zone. As zones are progressively emptied during consumption of the urea solution, as determined by the level sensor, each respective zone heater is de-energized. Because each horizontal zone is heated by a single heater, the solution is maintained at a substantially uniform temperature over the full depth of the tank without localized overheating.
