Abstract: Filling methods and systems are provided for a conformable fuel tank. In one example, a system comprises an active thermal management arrangement for the conformable fuel tank. The active thermal management arrangement comprises one or more recirculation passage for mixing hot fuel distal to an inlet port of the conformable fuel tank with cool incoming fuel flowing to the inlet port.

Abstract: A heating system and method for heating the interior of a vehicle, such as a motor vehicle, which has an air-air heat exchanger having a heat storage medium, and which is configured to transfer heat between exhaust air, drawn out of the interior, and intake air, supplied to the interior from the vehicle environment, between the exhaust air and the heat storage medium, and between the intake air and the heat storage medium.

Abstract: A pressurized gas tank for a motor vehicle includes a cylindrical axially extending housing with two end pieces axially connected thereto connected together by one or more tie rods configured for axial transmission of tensile force. The tie rods include an axially continuous through-channel configured to be connected to a vehicle cooling system including a circulating liquid coolant to cool the pressurized gas at least during refueling of the pressurized gas tank.

Abstract: The present invention relates to a method for measuring the dielectric properties of a sample with a scanning probe microscope. In particular, the invention relates to highly-localized optical imaging and spectroscopy on a sample surface using an atomic force microscope (AFM) probe mechanically driven at two oscillation frequencies, referred to herein as “active bimodal operation”, and a modulated source of electromagnetic radiation.

Abstract: Systems are provided for a cooling arrangement of an engine. In one example, a system includes a first coolant passage and a second coolant passage arranged in a cylinder bridge between directly adjacent cylinders, wherein the first coolant passage and the second coolant passage are separated from one another.

Abstract: A method for producing a compressed gas tank for a motor vehicle includes inserting a bundle of heat-conducting elements through an opening in a housing of the compressed gas tank and exerting a force on the bundle that radially expands the bundle within the housing beyond the size of the opening. The heat-conducting elements may be helically wound about a central axis when inserted through the opening with a torsional force applied to unwind the elements while radially expanding and reducing axial length of the bundle. A compressed gas tank for a motor vehicle includes a plurality of heat-conducting elements including at least one tube within a tank housing that extend axially along the tank and radially within the housing to a size exceeding an opening of the housing. The tube is configured to circulate coolant to cool compressed gas within the tank.

Abstract: Methods and systems are provided for a cooling system. In one example, a cooling system comprises a device for regulating a coolant flow, where the device is in force-fit connection to a plurality of crankshafts, each crankshaft corresponding to a single cylinder of a plurality of cylinders. The cooling system further comprises a plurality of injectors for injecting coolant onto outer surfaces of the plurality of injectors.

Abstract: The application relates to internal combustion engines, cylinder heads, exhaust passages, and shapes and configurations of the exhaust passages. The exhaust passage may have cross-sectional shapes formed by two limbs. The cross-sectional shape of the exhaust passage may change as the passage extends. The exhaust passage may also merge with other exhaust passage. The exhaust passage may be part of a cylinder head or an exhaust manifold.
