Oil Filtration

In this paper, PVA electrospun nanofiber was prepared on the surface of three different automobile engine oil filtration materials including polyester nonwoven, glass fiber nonwoven, and cotton pulp filtration paper. It was found that the substrate of cotton pulp filtration paper and the nanofiber layer had better adhesive effect. Then we A comparison of fiber diameter, pore diameter, filtration accuracy and pressure drop between the cotton pulp paper and nanofiber composite filtration material was then made. The results show that the nanofiber composite material had smaller pore diameter and filtration accuracy, higher pressure drop, and better oil filtration property. Additionally, the difference of pressure drop between the substrate and nanofiber composite material increased with increasing flow rate of experimental oil. The goal of this paper was use the electrospun nanofiber in the automobile engine oil filtration.

Oil Filtration

The main purposes of this paper are to research the structure and property of commonly used oil filtration materials on the basis of the hierarchical cluster method and to develop new filter material. For this objective we selected ten different oil filtration materials and made a comparison of their filtration properties. In addition, the hierarchical cluster method was used to classify these ten oil filtration materials into three different categories. Objective classification results in the case of data matrix of different properties had a rather accurate result, which was almost consistent with the result of subjective classification. It was found that three different kinds of filtration material had different structures and properties in practical application. In addition, the results indicate that the filtration property of the new filter developed on the basis of hierarchical cluster analysis was very close to the first material.

Oil Filtration

Oil filter is a part of a gasoline or diesel engine lubrication system designed to clean the engine oil. Depending on where it is installed, the oil filtration system, they are divided into three types: - through-flow filter, which passes through all the oil that the pump feeds into the engine. A pressure regulating by-pass valve is installed upstream of the filter to protect the gaskets with oil seals. If the filter element is too dirty, the valve directs oil flow past the filter, preventing oil starvation of the bearings. Keeps engine from failing due to lack of lubrication; - a partial-flow filter is mounted parallel to the main oil line and cleans only a portion of the oil that enters the engine. Gradually the whole volume of oil passes through the filter element, giving a fairly high cleaning efficiency. However, this method does not provide absolute protection of parts from chips and other abrasives; - the combination filter combines a full-flow and a partial-flow cleaning principle. It consists of two filter elements, one mounted parallel to the oil line and the other cut into it. This ensures maximum cleaning efficiency and long filter life. The filter elements are divided into two types according to their efficiency in removing fine impurities: coarse filters, which remove coarse impurities, and fine filters, which remove fine impurities. According to the design of the housing and the possibility of replacing the filter element, filters are divided into multiple (collapsible) and disposable (non-collapsible). Modern engines may use filters in the form of a cartridge, which is inserted into a special compartment. During operation, the oil is first routed to the filter and then through the oil channels to the interacting parts in the engine. This principle is used on all standard passenger cars. A settling filter (gravity filter) is a tank with a filter element and a settling tank in which impurities are deposited by gravity. The centrifugal filter operates similarly to the gravity filter, only dirt settles in it under the action of centrifugal force resulting from the rotation of the body

Oil Filtration

In 2006, an automatic lube oil filtration system with an automatic backflushing filter and a centrifuge for railway engines was already presented at the ASME spring technical conference in Aachen. The technical benefit of a centrifuge compared to a cartridge filter is the ability to collect smaller particles. The power to drive the centrifuge comes from the engine oil pressure. This engine oil pressure is dependent from the engine speed. Many operating profiles of locomotives are showing low engine speed and load e.g. while waiting in switchyard and under arctic weather conditions the engines keep idling even during “downtime”. Under those conditions a centrifuge is ineffective or even out of operation.

Nowadays, the creation of remotely-piloted aerial vehicles for various purposes is regarded as one of the most relevant and promising trends of aircraft development. FAU "25 State Research Institute of Chemmotology of the Ministry of Defense of the Russian Federation" have studied the operation features of aircraft piston engines and developed technical requirements for motor oil for piston four-stroke UAV engines, as well as a new engine oil M-5z/20 AERO in cooperation with NPP KVALITET, LLC. Based on the complex of qualification tests, the stated operational properties of the experimental-industrial batch of M-5z/20 AERO oil are generally confirmed.

Hydrophobic Material

A very low-density oil-absorbing hydrophobic material was fabricated from cellulose nanofiber aerogels–coated silane substances. Nanocellulose aerogels (NCA) superabsorbents were prepared by freeze drying cellulose nanofibril dispersions at 0.2%, 0.5%, 0.8%, 1.0%, and 1.5% w/w. The NCA were hydrophobically modified with methyltrimethoxysilane. The surface morphology and wettability were characterized by scanning electron microscopy and static contact angle. The aerogels displayed an ultralow density (2.0–16.7 mg·cm-3), high porosity (99.9%–98.9%), and superhydrophobicity as evidenced by the contact angle of ~150° that enabled the aerogels to effectively absorb oil from an oil/water mixture. The absorption capacities of hydrophobic nanocellulose aerogels for waste engine oil and olive oil could be up to 140 g·g-1 and 179.1 g·g-1, respectively.
