  • Publication number: 20150218981
    Abstract: Systems and methods are described for reducing friction within a transmission and an internal combustion engine including a PCV system. A gaseous fuel source is fluidly coupled to the transmission via a flow control valve and the transmission, in turn, is fluidly coupled to an air inflow line of the PCV system. The flow control valve is configured to control a flow of gaseous fuel into the transmission and there on into the PCV system and crankcase.

  • Publication number: 20150101566
    Abstract: A method for an engine, comprising: responsive to a pressure in a fuel tank being below a pressure threshold, injecting only a liquid fuel into an engine cylinder, the fuel tank storing the liquid fuel and a pressurized gaseous fuel partially dissolved in the liquid fuel. In this way, the pressurized gaseous fuel may be conserved, thus maintaining a pressure gradient within the fuel system and allowing for judicious use of the pressurized gaseous fuel, for example during cold start conditions.

  • Publication number: 20150071759
    Abstract: A method for controlling air flow through a compressor recirculation passage, comprising: during a first condition: reducing air flow through the compressor recirculation passage based on a margin, the margin based on a rate of air flow at a compressor inlet, a rate of air flow through the compressor recirculation passage, and a rate of EGR flow. In this way, the CRV recirculation flow may be controlled to be less than the amount that could potentially backflow into an air filter disposed in the air intake passage, thus preventing EGR contained in the CRV recirculation flow from fouling the air filter with soot, oil and water.

  • Patent number: 8950366
    Abstract: A method for operating a condensed natural gas engine, comprising injecting a mass of additive into the engine, the mass of additive a function of a mass-of-soot desired and producing a mass-of-soot during combustion, mass-of-soot produced a function of the mass of additive injected into the engine. By this method additional soot may be produced for heightened lubrication and valve protection.

  • Publication number: 20140331642
    Abstract: A method for a turbocharged engine, comprising: during high load conditions, in response to an elevated engine temperature, after port injecting a first quantity of a first gaseous fuel, direct injecting a second quantity of a second, liquid fuel at a first timing that is a function of a desired air-fuel ratio. In this way, engine power may be maximized while simultaneously decreasing the maximum combustion temperature and mitigating engine knock.

  • Publication number: 20140331970
    Abstract: A method for operating an engine, comprising port injecting a first quantity of a first gaseous fuel in a cylinder cycle and direct injecting a second quantity of a secondary injectant in the cylinder cycle as a function of a desired air-to-fuel ratio (AFR), the desired AFR based on a temperature of an engine cylinder valve. The desired AFR may be outside the AFR range available during natural gas combustion alone and thus allows for cooler engine operation.

  • Publication number: 20140331668
    Abstract: An engine system, comprising a first gaseous fuel source with a first gaseous fuel located therein coupled to one or more engine cylinders and an exhaust gas recirculation (EGR) system with a reform catalyst located therein, the reform catalyst reforming natural gas into a gas with a wider AFR operating range. The engine may thus operate at an AFR that may be outside of that available during natural gas combustion alone to allow for cooler engine operation.

  • Patent number: 8714123
    Abstract: Systems and methods for modifying oil pressure for a variable cam timing system are provided. In one example approach, a method comprises, in response to an operating condition, adjusting a valve coupled to a hydraulic variable camshaft timing actuator to initiate camshaft phasing and adjusting an oil pressure supplied to the valve based on a camshaft phaser position. If a camshaft phaser locking pin is in a home position, the method may further comprise reducing the oil pressure supplied to the valve for a predetermined time interval to a threshold amount to unlock the locking pin but not move the camshaft phaser and then increasing the oil pressure supplied to the valve to move the camshaft phaser.
