摘要:
In a method for controlling an inlet valve of an internal combustion engine having at least one cylinder with at least a first inlet valve and a second inlet valve, wherein the closing time of the first inlet valve is adjustable and the first inlet valve is so controlled that, at a first engine speed, the first inlet valve is closed before the closing of the second inlet valve and, at a second engine speed which is higher than the first engine speed, the first inlet valve is closed after the closing time of the second inlet valve.

In a centrifugal oil separator in an internal combustion engine including a centrifuge housing which is placed in a rotationally fixed manner onto a rotating centrifuge shaft, the centrifuge housing is manufactured from plastic and a metal bushing is integrated into the centrifuge housing and is slipped onto the centrifuge shaft.
摘要:
A cell culture device allows co-cultivation on both sides of a membrane and has an outer tubular body with upper end having an opening and lower end closed by the membrane, an inner surface and an outer surface, which can be colonized with biological material, a complementary tubular body whose inner diameter fits onto the outer diameter of the lower end and a hanger component with upper end and a lower end. A flange extends from the upper end and the outer diameter component fits the inner diameter of the outer tubular body. The outer tubular body in a first step is connected to the complementary tubular body to form a standing insert for a first cell cultivation, and in a second step wherein the outer tubular body is disengaged from the complementary tubular body and is attached to the hanger component for a second cell cultivation.
摘要:
In a device for changing the angle of rotation of a camshaft arranged in a cylinder head of an internal combustion engine relative to a drive wheel of the internal combustion engine, wherein a hydraulic adjusting arrangement is arranged between the drive wheel and the camshaft and is connected to a fluid circuit of the internal combustion engine, and wherein the fluid supply to the adjusting arrangement is controlled by an on/off valve, the on/off valve is mounted near the camshaft and is supplied with fluid via the camshaft.
