A hybrid drive, in particular for vehicles has a variable-ratio gear unit with a branch which can be driven by a primary motor. The gear unit is also connected in a rotationally rigid manner to a rotatable part of a first electric machine. A branch of the gear unit is connected in a rotationally rigid manner to a rotatable rotor of a second electric machine. Another branch connected in a rotationally rigid manner to an output shaft and to which the likewise rotatably arranged other machine component of the first electric machine is connected in a rotationally rigid manner. The rotor of the second machine can be fixed or released for rotation by a brake.

Hybrid drive for vehicles and the like

In an internal combustion engine with direct fuel injection having a piston disposed in a cylinder and a cylinder head which together define a combustion chamber, wherein a fuel injector is mounted in the cylinder head so as to inject fuel into the combustion chamber in a conical pattern whereby the fuel is mixed with combustion air to form a combustible mixture, the cylinder head has a shape around the conical fuel pattern which aids in providing combustible fuel/air mixture at least in an area adjacent the conical fuel pattern where a spark plug with electrodes is mounted such that its electrodes are disposed outside the conical fuel pattern.

Internal combustion engine with direct fuel injection

In a port-controlled two-stroke internal combustion engine with an engine block comprising a crankcase and a cylinder block including pistons connected to a crankshaft by crosshead rods with crossheads guided for linear movement with the pistons, and connecting rods extending between the crossheads and the crankshaft a partition structure is arranged between the crankcase and the cylinder block and includes hollow cylindrical sleeves which project axially into the cylinders to a point closely adjacent the undersides of the piston tops when the pistons are in their bottom dead center positions and the sleeves are spaced from the cylinder walls to form between the sleeves and the cylinder walls annular spaces for receiving the depending skirts of the pistons.
