Übersetzung für "Engine lubricant" in Deutsch

During operation of an internal combustion engine the existing lubricant pump delivers lubricant into the inlet passage 5 of the pressure-increasing pump.

TECHNICAL FIELD The present invention relates to a characteristic-map-controlled lubricant pump system with a lubricant pump for supplying a combustion engine with lubricant.

If it is possible to check whether the vehicle’s engine coolant and lubricant are stabilized at the test temperature, this period may be shortened.

The stated detergents generally have excellent efficiency in keeping valves and carburetor clean but, as mentioned above, behave neutrally to, i.e. have no adverse effect on, an engine lubricant and thus have no positive effect with regard to the desired sludge dispersing.

As a rule, for the sake of lubricating its components such as its camshaft 14, which serves to drive the individual pump pistons (not shown), the fuel injection pump 10 is connected to the lubricant circulatory system of the engine, so that lubricant is contained in the interior 15 of the housing 13.

Owing to their dispersing properties, they have an advantageous effect on the engine lubricant, which they can enter during operation.

It will be understood that when the engine is cold, because the oil is highly viscous, when the engine and the lubricant pump directly coupled thereto are started, the pressure at the discharge side of the lubricant pump initially raises relatively steeply because the resistance to flow of the oil through the lubrication points is relatively high.

If ammonia is used in the reductive amination in the second process, the reaction products of the ammonia usually display excellent efficiency with regard to keeping valves and carburettors clean, but they are at best neutral in their action on an engine lubricant, in particular with regard to their oil sludge-dispersing actions.

If instruments are available to check that the engine coolant and lubricant are stabilized at the test temperature, this period may be shortened.

The latter products generally have excellent efficiency in keeping valves and carburettors clean but are at most neutral in their effect on an engine lubricant, particularly with regard to their sludge dispersing effect.

For 30 years, we have been a reliable partner of the automotive industry and engine manufacturers, lubricant and additive producers as well as the chemical industry and engineering companies.

The hydraulic system situated with regard to driving between the camshaft 6 and the gas exchange valve 3 is connected to a hydraulic medium supply 14 of the internal combustion engine, here its lubricant circuit.

With increasing engine speed, the lubricant pressure increases and thus the pressure force exerted on the piston 6 increases.

For this reason, a type of emergency operation control at a higher pressure level is provided with the usual lubricant pumps in order to continue supplying the combustion engine with lubricant even in the event of a failure of the proportional valve.

The factors such as lubricant pressure, flow rate, engine rotational speed, lubricant temperature and the spring force applied to the actuating unit in this case can be taken into account separately from one another.

In this version, the common conveying device, i.e., for example, a common pump, is therefore used to supply both the impact mechanism and the internal combustion engine with lubricant.

The nozzle (1) as claimed claim 8 wherein the variable volume 13 (8) is delimited by a flexible element which during injection of the liquid is exposed to a pressurized fluid of the internal combustion engine, especially lubricant or fuel or cooling liquid, and is deflected out of its rest position to reduce the variable volume (8).

An arrangement of the damper within the casing of the engine is likewise conceivable, in particular when the damper is to be cooled via the engine lubricant.

The at least one second pressure chamber subjected to permanent onflow is so dimensioned in this case that upon a failure of the proportional valve, i.e. the sole application of the permanent lubricant pressure on the at least one second pressure chamber, the lubricant pump because of the spring counterforce onto the actuating unit remaining the same, continues operation at a higher pressure level and supplies the combustion engine with lubricant, i.e. in particular with oil.

In this case, the two shuttle devices can be switched in a coordinated manner such that the lubricant from the storage container of the engine lubricating device can be guided to the internal combustion engine, and the lubricant from the storage container of the impact mechanism lubricating device can be guided to the impact mechanism.

If the phase setter is supplied with pressure fluid in accordance with a rotational speed of the internal combustion engine, preferably by means of a pump which is driven by the internal combustion engine, for example a lubricant pump for supplying the internal combustion engine with lubricant, then the pressure of such a pressure fluid supply can be subject to major fluctuations within the operating range of the internal combustion engine.

In the engine, the lubricant is then very heavily loaded in terms of thermal oxidation, and a high degree of charging with pollutants, in particular soot, occurs.
