The method provides hydraulic pressure for mechanical work from an engine lubricating system in an internal combustion engine by supplying oil to an engine lubrication gallery for lubricating the engine and to at least one variable oil demand accessory. Each of the variable oil demand accessories has an individual pressure regulator. The output of the variable displacement pump is regulated based on the sum of fluid flow required by the engine lubricating system and the engine accessories, regardless of the engine output. The demand for fluid is determined by the individual pressure regulators on each of the engine accessories. In a preferred embodiment, an accumulator stores high-pressure fluid to be used to power the hydraulic accessories.

The invention relates to a delivery device (2) for a motor vehicle for delivering oil from an oil sump (3) to a lubricating oil circuit of an internal combustion engine (1), which delivery device hasas an oil pump (5) a double-stroke vane cell pump (28) having positive guidance of vanes (32). A direct drive (6) of the vane cell pump (28) via the internal combustion engine (1) is designed for a working point P2. An increased or reduced oil demand is compensated for by an electric drive (7) that can be connected. In this way, a compact and very small-dimensioned oil pump (5) can be employed.

The invention provides a dynamic oil limiting type thrust bearing of a turbocharger. The dynamic oil limiting type thrust bearing comprises a bearing body, a first thrust plate, a spacer sleeve, a thrust bearing plate and a second thrust plate. The first thrust plate and the second thrust plate are fastened to a rotary shaft and fixedly connected through the spacer sleeve which is connected to the middle of the thrust bearing plate fixed to the bearing body in a sleeving mode. A first bearing gap and a second bearing gap are separately formed between the first thrust plate and the thrust bearing plate and between the second thrust plate and the thrust bearing plate. The thrust bearing plate is provided with an oil inlet and a circumferential oil storage and distribution cavity communicating with the oil inlet. The spacer sleeve is provided with an oil limiting ring in the circumferential direction of the outer diameter. The oil limiting ring is located in the oil storage and distribution cavity. The dynamic oil limiting turbocharger has the beneficial effects that under the condition that normal oil supply to a bearing surface is ensured, dynamic bilateral reversing operation is achieved through the oil limiting ring and the oil storage and distribution cavity, the lubricating oil quantity on the non-bearing surface of the thrust bearing is limited, the total lubricating oil demand of the thrust bearing is decreased, and meanwhile, normal bearing of the bearing face of the thrust bearing is not affected.

The invention relates to an integrated cylinder head cover and an automobile engine. The integrated cylinder head cover includes a cover body, a camshaft mounting seat arranged in the middle of the cover body, a solenoid valve mounting seat and a variable valve mounting seat respectively provided at both ends of the cover body, and a first lubricating oil passage structure and the second lubricating oil channel structure; the first lubricating oil channel structure includes the camshaft delivery oil channel in the middle of the cover body, the camshaft lubricating oil channel on the camshaft mounting seat, and the variable valve The variable valve lubricating oil passage on the mounting seat, the camshaft lubricating oil passage and the variable valve lubricating oil passage are all in communication with the camshaft delivery oil passage; the second lubricating oil passage structure includes a solenoid valve located at the end of the cover body The delivery oil passage, and the solenoid valve lubricating oil passage located on the solenoid valve mounting seat. The invention can solve the problem in the related art that after the cylinder head cover is integrated with VVT, VVL and other mechanisms, the demand for engine oil is increased, which leads to the deterioration of the lubricating condition of the camshaft.
