摘要： A device for the determination of the alcohol content and/or the calorific value of fuels by measuring the characteristics of the fuel in a measurement cell in which a flow body that is at least partially wetted by the fuel is arranged. The accuracy and speed of this measurement is improved by providing a first electrode for the dielectric measurement of the fuel and a second electrode for the measurement of the conductivity of the fuel on the outside of the flow body. Preferably the first electrode for the measurement of the capacitance, its outer connection and the walls of the measurement cell form a mechanically rigid system. It can also be expedient to mount the measuring circuit for the measurement of at least the capacitance directly on the housing of the measurement cell.

摘要： An internal-combustion engine includes a cylinder having an upper, generally planar bounding surface formed by an inner wall portion of a cylinder head; a fuel injection device and a spark plug held in the cylinder head and opening into the cylinder; a piston axially slidably disposed in the cylinder; a combustion chamber defined between the upper bounding surface of the cylinder head and the top piston face when the piston is in its upper dead center position; and an annular ridge situated on the top piston face. The annular ridge subdivides the combustion chamber into an inner partial combustion chamber and an outer partial combustion chamber surrounding the inner partial combustion chamber. The inner partial combustion chamber is situated in an effective range of the fuel injection device and the spark plug. Further, throughgoing apertures are provided in the annular ridge for maintaining a continuous communication between the inner and outer partial combustion chambers.

摘要： A high-pressure gas compressor comprises a single-acting cam driven piston with a pressure compensation chamber disposed between the piston and the cam. A roller tappet assembly transmits reciprocating motion from the cam to the piston. A pressurized gas directed to the pressure compensation chamber offsets forces acting on the piston from the compression chamber gas pressure, thereby reducing Hertzian pressure between the tappet roller and the cam. Overall efficiency and durability can be improved by reducing friction between compressor components, for example by employing thin film coatings to reduce friction, pressurized oil lubrication systems and higher cylinder bore diameter to piston stroke ratios. The service life of gas seals and compression efficiency can be improved by thermal management strategies, including liquid-cooled compressor cylinder liners and intercoolers between compression stages. Employing a poppet-style intake valve and reducing parasitic volume in the compression chamber can improve compressor volumetric efficiency.

摘要： An internal combustion engine comprises a fuel injection nozzle for injecting a gaseous fuel directly into the combustion chamber. Installed in close proximity to the fuel injection nozzle is an ignition device, comprising a sleeve that provides a shielded space around a hot surface igniter. The sleeve restricts flow between the shielded space and the combustion chamber. An inlet opening in the sleeve allows air and fuel to enter the shielded space to form a combustible mixture therein. The sleeve contains a substantial amount of the combustible mixture within the shielded space until it ignites and pressure builds within the shielded space to propel a combustion flame through at least one discharge opening that is oriented to direct the combustion flame into contact with the fuel spray roots emerging from the fuel injection nozzle.
