Based on this new period and considering the lubricant oil cost of R$ (U$ ) per liter (pricing for Cascavel, State Parana, January, ), the oil cost per EOH of the engine used in this study will decrease from U$ toan economy of U$ a year (10 engine operating hours daily), which is equivalent to % of the.

The lubricating oil for a diesel engine needs a variety of properties. It must be able to clean engine components and keep them clean, it must neutralize acids, transfer heat, fight rust and corrosion in addition to its main job of lubricating the engine for a very long time [1, 2].File Size: KB.

A simple system or mechanism for engine Oil (lubricating oil) deterioration monitoring is a need. As engine oil is an important element in I C engines and it is exposed to various strains.

Used lubricating oil analysis is a widely used tool for predictive and proactive maintenance. The traditional property test includes kinematic viscosity, total base number, fuel dilution, wear metals and insolubles. Insolubles include soot, wear metals and oil insoluble resinous matter originating from oil or additive by: Lubricating oil is as important for an engine as blood for a human.

Today, a lot of information about human health can be obtained from blood tests. And so it is for diesel engines.

Furthermore, biodiesel may dilute or contaminate the lubricating oil of engines.

Even worse is that if the quality of biodiesel is not good and contains high degree of unsaturated fatty acids, it would tend to polymerize with the lubricating oil, forming sludge and increasing engine wear.

Perhaps the most effective and least expensive natural gas engine condition-monitoring technique available today is the analysis of the engine’s lubricants. Unfortunately, many natural gas engine operators take the lubricant for granted and do not consider the engine oil as another component of the machine, which should be as closely monitored as any other system within the : Lloyd Leugner.

Using vegetable oils as fuel for diesel engines in the long term may cause some extremely serious problems, such as an increase in toxic emission and pollutants, reduction in engine power, and degradation of lubricating oil (LO) due to deposit formation, abrasion, and wear, as well as damaged by: In addition, the oil in diesel engines should suspend soot particles resulting from partial fuel combustion to prevent depositions.

Performance reduces considerably if the lubricant is saturated. Furthermore, the analysis of in-service lubricating oils gives information about engine-related functions to detect harmful operating conditions or component : Bruker Optics. Waste lubricating oil refers to the engine oil, transmission oil, hydraulic and cutting oils after use.

It is also refers to the degradation of the fresh lubricating components that become contaminated by metals, ash, carbon residue, addition to asphaltic compounds which result from the bearing surface of the engines [2].

Effects of Exhaust Gas Recirculation on the Degradation Rates of Lubricating Oil in a Heavy-Duty Diesel Engine The specific goal of this project was to determine if there is a difference in the lube oil degradation rates in a heavy-duty diesel engine equipped with an EGR system, as compared to the same configuration of the engine Cited by: 4.

The present joint project focuses on RME being the most important representative of the biofuels of 1st generation in Europe. Traditional oil analysis methods - e.g. acidity and viscosity measurements - have been used to monitor lubricant conditions. These methods can detect when the useful life of a lubricant is over but fall short when trying to gain insight on how long a lubricant in current use could last.

Addition of metallic wear debris in the lubricating oil samples drawn after regular interval from both engine operating phases was investigated. Relatively higher concentrations of all wear metals were found in the lubricating oil of the EGR-operated engine, which indicates higher wear of various engine Cited by: Diesel engines also leads to the formation of soot particles dissolving in the lubricating oil.

All these chemical processes change the properties of the lube oil. If for example the base reserve of the oil is depleted and carboxylic acids are not neutralized anymore corrosion is facilitated.

Introduction. We have been studying about lubricating oil system used in marine diesel engines in past several articles and learnt about crankcase lubrication system, cylinder lubrication system and so forth. In this article we will learn about some of the basic properties of the lubricating oil used in these systems and ways to take care of the same.

Severe engine damage can occur due to fuel dilution in lubricating oil, as high fuel levels (>2%) in a lubricant can lead to decreased viscosity, loss of dispersancy, oil degradation, and loss of oxidation stability.

In internal combustion engines, fuel dilution is a major cause for lubricant failure and typically occurs as a result of not only improper fuel-to-air ratio, but also due to Author: AMETEK Spectro Scientific. Analysis of the Increase Level of Vibration in an Internal Combustion Engine due to the Degradation of the Lubricating Oil When analyzing vibrations in internal combustion engines, it is noticed that the greatest sources of vibrations are generated by combustion and mechanical : Claudio Marcio Santana, Jose Mautone, helder almeida.

Sources of Boron. Boron is an additive metal commonly used in detergent additives, and occurs in some EP or AW additive chemistries.

Only when the boron level deviates more than 25% from the new oil or reference value should a concern be raised, but the likeliest cause if mixing or topping-off with a different product. But beginning indevelopments in the heavy-duty industry would lead to changes in conventional thinking in the field of used engine oil analysis.

First, diesel fuel sulfur levels were decreased to just 15 ppm for on-highway engines and combustion became more efficient, resulting in less soot entering the engine oil and a reduction in hard.

the particular analysis. Wear metals are typically present in oil as metallic particles rather than dissolved in the oil. The particle size and concen-tration of individual wear metals in oil differ from one element to another and depend engine type, the age of the oil and the efficiency of the oil filter.

Diesel-like Fuel Obtained by Catalytic Pyrolysis of Waste Engine Oil Mustafa Balat * Sila Science & Energy Unlimited Company, University Mahallesi,Trabzon, Turkey ABSTRACT The aim of this study is to obtain gasoline like fuel from waste engine oil by catalytic pyrolysis which can be used in internal-combustion engines.
