  • 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: 20150101571
    Abstract: A control apparatus for an internal combustion engine is provided which can accurately correct a valve timing deviation of an intake valve caused by a variable operating angle mechanism or variable phase mechanism. A variable operating angle mechanism (28a) for making the operating angle of an intake valve (24) variable is provided. Operating angle command values (operating angles 1 and 3) of two points in front and back at which the intake air amount is decreased by a predetermined amount with respect to the value that is judged to be a maximum value of the intake air amount when the operating angle (command value) is kept changing, are acquired. Then, an intermediate value which is at an equal distance from the operating angle command values of the two points is calculated as the maximum operating angle command value.

  • Publication number: 20150090224
    Abstract: A highly-efficient, yet simply constructed internal combustion engine includes an intake cylinder to accommodate intake and pre-compression of an oxidizing agent, a combustion cylinder to accommodate a further compression of the oxidizing agent, an injection and ignition of fuel, and a partial expansion of combustion gases produced by the ignition of fuel; and an exhaust cylinder to accommodate a further expansion of the combustion gases and subsequent exhausting of the further expanded combustion gases. A reciprocating piston is inside each of the intake, combustion and exhaust cylinders and a crankshaft is coupled to the reciprocating pistons. A first transfer passage facilitates flow of the pre-compressed oxidizing agent from the intake cylinder to the combustion cylinder and a second transfer passage facilitates flow of the partially-expanded combustion gases from the combustion cylinder to the exhaust cylinder.

  • Publication number: 20150068494
    Abstract: A method of controlling fuel injection in an internal combustion engine is presented. A drive signal is generated for each injection event, with which the injector is kept open to spray fuel in accordance with a requested fuel quantity. The drive signal has a duration based on a pulse width that is determined from an injector-specific correspondence function defining the pulse width vs. a corresponding open time variable representative of injector open time. The open time variable is determined on the basis of a master performance function defining the requested fuel quantity in function of the open time variable.

  • Publication number: 20150059700
    Abstract: A method for controlling an engine supplied with multiple fuels in which the vapor purge flow into the engine from multiple vapor storage devices each coupled to a respective, but equal number of multiple fuel tanks controlled to have the same proportion of total vapors purged as a proportion of liquid fuel delivered to the engine from said respective one of the said multiple fuel tanks. The method includes increasing the delivery of fuel from one of the multiple fuel tanks containing fuel with the highest-octane rating of all the fuel tanks when the vapor storage canister coupled to the fuel tank with the highest-octane fuel is not being purged of its fuel vapors. Additionally, the method further comprises a feedback control responsive to an exhaust gas oxygen sensor to adjust said fuel delivered from said multiple fuel tanks to the engine to maintain engine air-fuel ratio around stoichiometry.
