A exhaust-gas heat management system includes a catalytic converter in the exhaust-gas train of an internal-combustion engine, a cover enclosing the catalytic converter, and thereby realizing a cavity for holding a latent-heat storage PCM, at least two fluid connections between the cavity and the collecting vessel, and a pump device for activating and deactivating a PCM circuit between the cavity and the collecting vessel by means of the fluid connections. A method comprises determining an operating state of the internal combustion engine, determining the catalytic converter temperature, determining the PCM temperature, activating the PCM circuit if the PCM temperature is above a phase transition temperature of the PCM, and the internal combustion engine is in a switched-on operating state or the internal combustion engine is in a switched-off operating state and the catalytic converter temperature is below a light-off temperature of the catalytic converter.

Examples are provided for switching an engine fuel supply. One example system includes a direct-injection engine including a cylinder, an LPG tank for storing a LPG fuel, a CNG tank for storing a CNG fuel, a gas switching valve, a high-pressure pump connected between the LPG tank and the gas switching valve, a pressure-limiting valve connected between the CNG tank and the gas switching valve, a fuel distributor configured to be supplied with one or more of the LPG fuel and the CNG fuel via the gas switching valve, an LPG injection valve coupled to the cylinder, a CNG injection valve coupled to the cylinder, the LPG injection valve and the CNG injection valve configured to be supplied with fuel via the fuel distributor; and a controller configured to control the gas switching valve depending on an aggregate state of the fuel disposed in the fuel distributor.

Internal combustion engine and method for operating an internal combustion engine

An applied-ignition internal combustion engine having at least one cylinder head comprising at least one cylinder and having a rotatably mounted crankshaft is provided. In the internal combustion engine each cylinder has an inlet opening, which is adjoined by an intake line, and an outlet opening, which is adjoined by an exhaust-gas line, each opening being equipped with a valve, each cylinder comprises a combustion chamber which is jointly formed by a piston crown of a cylinder-specific piston, by a cylinder liner and by the cylinder head. Additionally, the crankshaft is articulably connected to the piston of each cylinder, such that, as the crankshaft rotates about an axis of rotation, the piston oscillates along a cylinder longitudinal axis, where the cylinder longitudinal axis is perpendicular to the axis of rotation of the crankshaft.

Methods and systems are provided for a pressure tapping device for a motor vehicle where a portion of the pressure energy generated at the fuel storage reservoir is transmitted to a working medium, physically separate from the fuel via the pressure tapping device. The pressure tapping device is fluidically coupled to a pressure actuator and enables the pressure operation via transmission of the pressure energy and adjustment of valves diverting flow from the fuel storage reservoir to the engine intake through the pressure tapping device.

A method for operating an internal combustion engine is provided. The method includes during a first operating condition, operating two primary cylinders and two secondary cylinders to perform combustion, the two primary and secondary cylinders arranged in an inline configuration, the two primary cylinder adjacent to one another, the two secondary cylinders adjacent to one another, and the secondary cylinders positioned 175&#xb0;-185&#xb0; out of phase relative to the two primary cylinders and during a second operating condition, selectively deactivating the two secondary cylinders to perform combustion in only the two primary cylinders.

The application describes a system for an engine comprising a direct injection nozzle for injecting gaseous fuel into a cylinder of an engine in a second operating mode; an intake injection nozzle for injecting liquid fuel into an intake port of the engine in a first operating mode; and a valve gear suitable to adjust timing of opening and closing of an inlet valve. Preferential injection of a gaseous fuel such as compressed natural gas directly into the cylinder increases efficiency and allows for reduced heat exposure to the lesser used liquid gas injectors mounted in the intake port, reducing coking of these injectors.
