Abstract:

The objective of this study is to measure how the viscosity of engine oil changes with temperature. Six different commercially distributed engine oils (primarily intended for motorcycle engines) of 10W–40 viscosity grade have been evaluated. Four of the oils were of synthetic type, two of semi–synthetic type. All oils have been assumed to be Newtonian fluids, thus flow curves have not been determined. Oils have been cooled to below zero temperatures and under controlled temperature regulation, kinematic viscosity (mm2 / s) have been measured in the range of −5 °C and +115 °C. Anton Paar digita

Abstract:

Lubricant degradation by additive depletion, contamination and build-up of degradation products deteriorates lubrication performance. It can be expected that engine oil degradation also has an impact on performance parameters. Engine development tends to higher power density, lower engine oil viscosity to optimize fuel efficiency, which heavily stress engine oils and thus demand increased oil performance. Correlations between engine oil degradation, friction and wear during an engine oil’s lifetime are a valuable asset in engine development towards performance, longevity and cost reduction. He

Introduction. During the combustion of diesel fuel in a diesel engine with an increased fuel supply, as a result of its incomplete combustion, soot particles are formed, which are either released into the atmosphere or inevitably enter the engine oil.

Soot is very small particles formed by a complex reaction mechanism in the flame of a fuel-rich region during the combustion of hydrocarbons in the absence of air, mainly consisting of a mixture of amorphous carbon and organic matter.Materials and methods.

Introduction. The reliability and service life of an engine is largely dependent on the quality of the engine oil. Without oil at the proper level of performance, an internal combustion engine can suffer from wear and tear, which in many cases can lead to engine failure. One of the factors in the loss of the quality level of engine oil is its contamination. For example, kinematic viscosity will gradually increase as the engine oil becomes contaminated with soot, dirt and sludge; or it may be oxidized. If the viscosity of the engine oil is too high, the engine must do extra work to overcome the

Abstract:

Many attempts to use vegetable oils as fuel have been performed since the early days of the Diesel engine. When a Diesel engine is used with vegetable oil fuel for a short period of time, the performance and global efficiency are usually very close to Diesel fuel. However, during long-term engine tests with vegetable oils as fuel, heavy deposits build-up can be observed in the combustion chamber. These deposits can lead to engine breaks. A fuel droplet vaporization experiment proved that the deposits build-up is mainly controlled by the combustion chamber temperature. A new thermally insulated

Abstract:

The characteristics of some Nigerian engine oil, petrol and fuel mixture were studied. Engine oil, petrol and fuel mixture are used daily on the Nigerian roads, homes, offices etc. in various machines (engines) as lubricating oils. One important use of these lubricating oils is to reduce  friction between parts of a machine in relative motion. The measurement of viscosity of the engine oil and fuel mixture was carried out to determine the characteristics of the oil and the blend with respect to their use. Using an Ostwald Viscometer method, the viscosities of the engine oil and petrol wer

Annotation – The influence of the structural characteristics of engine lube oil on the dynamics of a marine diesel engine is considered. It is indicated that micron layers of marine engine lube oils separating the contact surfaces of marine diesel engines acquire the properties of liquid crystals and are characterized by an ordered molecular structure. The qualitative indicator of this structure is the degree of ordering of the molecules, and the quantitative indicator is the thickness of the ordered (boundary) lubricating layer.

The use of pure vegetable oils is usually not possible due to its properties, especially for higher density and viscosity.

Without adjustments of the combustion engine the fuel can burn blended with vegetable oil so it does not significantly exceeded the requirements of the internal combustion engine to its properties.

To develop an oil change technology based not on operating time, but on the actual state, it is necessary to analyze the change in the characteristics of engine oil, which in the end will reduce the cost of operation, maintenance and repair of machi

Abstract:

While being highly fuel-efficient, diesel engines are defined by relatively high emissions, which have a negative impact on people and the environment. In the future, most European countries plan to abandon the use of diesel engines after 2030. One way to use this type of engines is to convert them to alternative fuels from renewable energy sources, such as vegetable oils (rapeseed, sunflower and soya bean oils). A significant advantage of vegetable oils is that when they hit the ground, they break down in a couple of weeks. Sulfur oxides are virtually absent due to the small amount of sulfur

On the face of the upcoming energy crisis, vegetable oils have come up as a promising source of fuel. They are being studied widely because of their abundant availability, renewable nature and better performance when used in engines. Many vegetable oils have been investigated in compression ignition engine by fuel modification or engine modification. The vegetable oils have very high density and viscosity, so we have used the methyl ester of the oil to overcome these problems. Their use in form of methyl esters in non modified engines has given encouraging results.Coconut oil copra , Waste veg
