Description
Technical field
The utility model patent relates to engine lubrication system, is specifically related to a kind of petrol engine oil sump, belongs to automotive powerplant technical field.
Background technique
Oil sump is component important on motor, its major function is to store and provide lubricant oil for lubrication system, and forming crankcase together with framework, the principle of oil sump design is to guarantee that motor, under different operating conditionss, can provide machine oil for engine lubrication system.The whether smooth and easy quality that is all directly connected to whole motor of the structural design of oil sump, sealability, oil storage function, oil suction, wherein any one disabler, the lighter causes user's complaint, and severe one causes motor to damage.
Oil sump is generally sheet metal punching press or aluminum alloy cast appearance one-tenth.Sheet metal oil sump cost is lower, but vibration noise is relatively large.Aluminum alloy oil sump intensity is high, NVH better performances, but cost is slightly high.
Oil sump, when storing machine oil, also will play the effect of in-cylinder combustion noise being carried out to hermetic barrier.Due to it, to be subject to complete machine oscillation excitation stronger, and the relative engine cylinder-body of rigidity is lower, easily produces local mode's distortion, and the acoustic cavity that the sealing air between oil sump and cylinder body forms easily produces transient pressure fluctuation, radiation medium-high frequency section noise.Therefore, oil sump design need to promote as much as possible intensity according to cae analysis and verification experimental verification under the target of design space and weight, optimizes NVH performance.
Comprehensive above-mentioned oil sump working condition, requires oil sump to have the combination properties such as good intensity, thermal conductivity, sound insulation property and endurance.
Oil sump, according to the difference of lubricant oil mass storage position, can be divided into wet type and dry sump two classes.
Wet sump is traditional lubrication system architecture form, and it is arranged on the cylinder body framework of motor, forms engine crankcase together with cylinder body, as the container of storage, collection and cooling machine oil.The oil sump that the utility model relates to belongs to wet sump.
The machine oil that dry sump circulates while only collecting engine operation forms crankcase together with engine cylinder-body.Storing machine oil is to realize by extra collecting box.Its lubrication system specific is to be back to lubricant oil in oil sump constantly by one or two oil scavenge pumps, to be extracted out, and is transported to the oil tank that is arranged in external engine, then by an oil pump, lubricant oil delivered in the lubrication system of engine interior and gone.The advantage of dry sump is to guarantee car load uninterrupted fuel feeding under the condition significantly tilting, and avoids lubricant oil to contact with the high-temperature gas in crankcase simultaneously, can effectively reduce machine oil oxidation deterioration, but cost is higher.
