  • Patent number: 11821383
    Abstract: A control apparatus for an engine includes a crank angle sensor and a processor. The processor acquires a first crank angular velocity difference which is a change in a crank angular velocity in a first region. The first region includes a rotational change correlated with an engine torque output. The processor acquires a second crank angular velocity difference which is a change in the crank angular velocity in a second region. The second region includes a rotational change correlated with a combustion rate attributable to an air-fuel ratio. In a case where the first crank angular velocity difference is less than or equal to a first threshold and the second crank angular velocity difference is less than or equal to a second threshold, the processor performs an increase correction on a fuel amount to be supplied to the engine.

  • Patent number: 11808238
    Abstract: A method for supplying hydrogen-operated internal combustion engines with oxygen, wherein an inert gas is cycled. An economical local supply of pure oxygen for a closed-cycle hydrogen engine with argon cycling is realized by separating the oxygen from the atmosphere without relying on the useful work of the engine. OSM ceramics and exhaust gas heat and low oxygen partial pressure of the exhaust gas are used to generate oxygen. Two reactors filled with OSM ceramics are used, these reactors being alternately purged with exhaust gas and regenerated with air. Losses of inert gases and the entry of atmospheric nitrogen are avoided by intermediate purging with steam. The steam is generated by the heat of the exhaust gas or exhaust air. A mixture of water vapor, inert gas and oxygen is formed during purging. Subsequently, the oxygen content in the gas phase is markedly increased since water vapor is condensed out.

  • Patent number: 11808232
    Abstract: A port fuel injection system includes a fuel pump configured to produce a flow of pressurized liquid fuel at a pressure between 10 and 50 bar. A fuel rail is connected to receive the flow of pressurized liquid fuel from the fuel pump, the fuel rail. A plurality of fuel injectors, including one fuel injector positioned in the intake port of each engine cylinder upstream of the intake valve for the engine cylinder are connected to receive pressurized fuel from the fuel rail. An engine control unit (ECU) receives signals from sensors on the internal combustion engine and is programmed to actuate the fuel injectors to deliver fuel to each engine cylinder over a full range of engine operating conditions. A port fuel injection system with high pressure and fast acting fuel injectors improves fuel delivery and performance over the full range of engine operating conditions.

    Abstract: A method for estimating pressure in an intake manifold of an indirect injection combustion engine. A pressure sensor measures pressure in the intake manifold, the intake manifold being in fluidic communication with a combustion cylinder, a piston guided in translation in the combustion cylinder and connected to a rotating crankshaft. The method includes: measuring, with the pressure sensor, a maximum pressure corresponding substantially to a maximum pressure in the intake manifold during a preceding cycle of the engine; measuring, with the pressure sensor, a minimum pressure corresponding substantially to a minimum pressure in the intake manifold during the preceding cycle of the engine; determining a pre-calculated average pressure correction factor from a crankshaft angular position and from an engine speed; and estimating the pressure in the intake manifold for the crankshaft angular position of the current engine cycle from the average correction factor and from the minimum and maximum pressures.
