Opis:
The paper presents the results of lubricating properties tests of Titan Truck Plus 15W40 motor oil. Tested oil was used in Caterpillar 3512B high-speed engines, which propelled the tug boat. The lubricating properties parameters were determined for fresh oil and used oil samples. Builder of Caterpillar 3512B engine recommends lubricating oil change after every 1000 hours of operation. Lubricating oil samples were taken from engine oil system after 342 hours of service and after 1024 hours of service, it means just before lubricating oil change. The test results were collected by means of a four-ball extreme pressure tester T-02 according to Polish Norm PN-76/C-04147. The following lubricating properties parameters were determined: weld load Pz, maximum nonseizure load Pn, seizure load Pt and load wear index Ih. Investigations showed that for used oil samples maximum nonseizure load and seizure load increase but weld load and load wear index decrease. These results indicate that used oil has higher boundary layer resistance (better antiwear properties) but worse antiseizure properties, which are determined in hard working conditions of the sliding node elements. In author’s opinion, worsening of the antiseizure properties results of solid impurities presence, which come from lubricating oil deterioration process. To verify that thesis the detail analysis of the tested oils chemical content has been made. Spectrol Q100 spectrometer, which can specify content of 24 chemical elements in the lubricating oils was used for this purpose.

The paper presents the results of lubricating properties tests of Marinol RG 1240 motor oil used in trunk piston marine diesel engines and modified by chemical interaction aftermarket additives – Motor Life Professional and Mind. The test results were collected by means of a four-ball extreme pressure tester T-02 according to Polish Norm PN-76/C-04147. The following lubricating properties parameters were determined: weld load Pz, maximum nonseizure load Pn, seizure load Pt, load wear index Ih and load limit of wear Goz. Investigations showed that tested chemical interaction aftermarket additives improve load wear index Ih, and seizure load Pt (in case of Motor Life Professional), simultaneously impair maximum non-seizure load Pn. Weld load Pz remains on the same level. But the load limit of wear Goz which characterises the wear resistance in extremely hard working conditions increases considerably- 542% for tested oil with the addition of 5% by volume of Motor Life Professional and 520% with the addition of 5% by volume of Mind additive. These results indicates that tested aftermarket additives can form additional boundary layer (independent of lubricating oil boundary layer) which activates in extreme working conditions (very high temperatures and loads) of the sliding node elements. That layer could protect machines elements against seizure. In authors opinion, modifying of motor oils (provided with antiwear and antiseizure additives by the manufacturer) by chemical interaction aftermarket additives can increase durability and reliability of the machine elements especially in hard working condition for example frequent starts and load changes, overloads, operation in polluted atmosphere (transport, mining, building engineering etc.).

W artykule przedstawiono wyniki badań własności smarnych oleju handlowego silnikowego Marinol RG 1240 stosowanego w bezwodzikowych silnikach okrętowych oraz modyfikowanego preparatem eksploatacyjnym o działaniu chemicznym Motor Life Professional (MLP). Badania wykonano na aparacie czterokulowym T-02 zgodnie z PN-76/C-04147. Wyznaczono następujące wskaźniki własności smarnych: obciążenie zespawania Pz, obciążenie zacierające Pt, obciążenie niezacierające Pn, wskaźnik zużycia pod obciążeniem Ih oraz graniczne obciążenie zużycia Goz. Modyfikowanie oleju preparatem eksploatacyjnym Motor Life Professional w zdecydowany sposób wpłynęło na zwiększenie odporności na zużycie i poprawę własności przeciwzatarciowych środka smarowego (wzrost Goz oraz Ih). Pozostałe wskaźniki (Pz, Pt) pozostały na tym samym lub nieco niższym poziomie (Pn).

The test results were collected by means of a four-ball extreme pressure tester T-02 according to PN-76/C-04147. The following lubricating properties parameters were determined: weld point Pz, non-seizure point Pn, seizure point Pt, load wear index Ih, and load limit of wear Goz. Investigations showed that the modification of lubricating oil by Motor Life Professional surface active agent considerably increases the wear resistance and antiseizure properties – increase of Goz and Ih parameters. The remaining parameters are unchanged (Pz, Pt) or a little lower (Pn).

Opis:
W pracy zbadano wpływ udziału procentowego zagęszczacza litowego na właściwości reologiczne kompozycji smarowej w zakresie liniowej i nieliniowej lepkosprężystości. Podczas badań zastosowano dwa testy oscylacyjne: test przemiatania amplitudy odkształcenia oraz test przemiatania częstotliwości odkształcenia. Test przemiatania amplitudy umożliwia ocenę stabilności mikrostruktury zagęszczacza w smarze plastycznym z podziałem na obszary liniowej i nieliniowej lepkosprężystości pod wpływem siły ścinającej, przy stałej częstotliwości i zmiennej amplitudzie odkształcenia. Testu przemiatania częstotliwości używa się głównie przy małych częstotliwościach oscylacji i stałym odkształceniu w celu zbadania mikrostruktury w obszarze liniowej lepkosprężystości. Badania przeprowadzono z wykorzystaniem reometru rotacyjnego Physica Anton-Paar MCR 101 pracującego w układzie stożek-płytka.
The effect of lithium thickener content on rheological properties of grease compounds in linear and non-linear viscoelastic regimes was investigated in this work. During the study, two oscillation tests were used: amplitude of strain sweep test, and frequency of strain sweep test. The amplitude sweep test allows one to assess the stability of the thickener microstructure in lithium grease in the linear and non-linear viscoelastic region under shear load at constant frequency and changeable strain amplitude. Sweep frequency tests are used mainly at low-frequency oscillation and constant strain to investigate the microstructure in the linear viscoelastic region. The study was carried out using a rotational rheometer, Physica Anton-Paar MCR 101m, with cone and plate geometry.

The article deals with the experimental detection of the tribotechnical parameters for two different types of sliding bearings which are intended for operation without an additional lubrication due to the increasing requirements in ecology and environment. The dominant tribotechnical parameters of the self-lubricating bearing are the coefficient of friction and temperature. To determine these parameters, an experimental method was applied in this paper. The introductory part deals with materials of self-lubricating sliding bearings, their properties and usage. The experimental part consists of the evaluation of friction characteristics and geometric change of a surface after sliding pairs were being worn. Experimental examined sliding pairs comprise a sliding bearing and the shaft. The aim of this research was to determine the effect of radial force on tribotechnical parameters in order to predict the behavior of examined sliding bearings in real operating conditions.

Opis:
The paper presents literature review concerning the aftermarket additives used in lubricating oils. Classification, principle of operation and scientific research of aftermarket additive operational effectiveness was presented. In majority of cases lubricating oils modified by aftermarket, additives are tested by means of a four-ball extreme pressure tester T-02 or friction machine T-05. Tester T-02 is used to determine lubricating oil parameters like weld load Pz, maximum non-seizure load Pn, seizure load Pt, load wear index Ih and load limit of wear Goz according to Polish Norm (PN-76/C-04147). Investigation of the tribological properties (friction force, wear of the matching elements) is executed by means of friction machine T-05. Until now, scientific research does not result in unequivocal assessment of the aftermarket additives. It come from big variety of aftermarket additives (chemical interaction aftermarket additives, additives that contain molecules of solid lubricants, additives that are able to form conditions for selective transfer lubrication) and their various principles of operation. Now the chemical interaction aftermarket additives have the widest application. These additives join permanently with lubricating oil, so they do not precipitate on the filters and do not create heat-insulating layers unlike the additives which contain molecules of solid lubricants (for example PTFE). Chemical interaction aftermarket additives improve antiwear (AW) and antiseizue (EP) properties of lube oils, decrease temperature in friction area and consequently minimize wear of the machines metal elements. Their functioning efficiency is usually the highest in hard working conditions (high loads, polluted environment, deteriorating technical condition of friction node elements) and in case of oils worse equipped with AW and EP additives (machine and hydraulic oils). In case of polymers, the influence of aftermarket additives is ambiguous.

Opis:
Lubricating oils are characterized by improving quality. It is obtained by additives which are the integral part of the lubricants. Nevertheless, in extreme hard working conditions of the tribological systems (high pressures, velocities and temperatures, temporary lubricating lack during starting) the machine elements are not secured enough. Consequently the idea to introduce the additional substance - operating preparation into tribological systems (with the lubricating oils) appeared a few years ago. Owing to that, the lubricating oils with better antiwear and antiseizure properties are obtained. The boundary layers created on cooperating elements surfaces are able to carry bigger load and also friction resistance and wear of these elements decrease. The paper presents literature review concerning the operating preparations used in lubricating oils. Different opinions about operating preparations functioning can be found in the professional literature - from harmfulness or weak effectiveness to good efficiency and big technical, economical and ecological meaning. In author's opinion, in extreme working conditions of tribological systems the operating preparations (especially the chemical interaction preparations) ensure additional and effective protection of machine elements. The functioning efficiency ofthe operating preparations is usually the highest in case of deteriorating technical condition of tribological system elements.

Opis:
The problem of lube oil consumption has been the point of interest of scientists for years,first because of economy and later - because of stringent standards of environment protection. From the point of economy lube oil consumption is not a problem of modern engines. On the other hand even a brief look proves that there is a quite wide range of admissible consumption from negligible values up to even l litr per 100 km. The question is why this range is so wide. Possible answer is that engine manufacturers leave so wide margin taking into consideration situations of very short trips, mainly in towns, when engine runs not fully warmed up with greater clearances, especially within the piston-cylinder assembly. Any oil consumption results in emission of particulate matter, which conveys a weighty number of hydrocarbons of which the most manifest serious hazardous properties, mainly carcinogenic ones. Nowadays, standards of environment protection require for instance the use of diesel particle filters and the excessive oil consumption could lead to the premature damage of these devices. Correct operation of the DPF could be disturbed not only by the excessive oil consumption but also by the use of improper oil, i.e. the non-low ash one. Certain additives that improve oil properties could produce ash as a result of oil combustion, which could clog filter irreversibly.

Opis:
During normal operation, oxidation products gradually foul lubricating oil and external contaminants like fuel, water, sulphur compounds and friction nodes wearing products. As a result, lubricating oil changes its properties, among other things viscosity. In normal service conditions of marine diesel engines lubricating oil viscosity increases due to vaporizing of lube oil light ends during operation in high-temperature areas and oxidation process. Quantity of organic particulates accumulated in lubricating oil increases as a result of oxidation process. Oxidation products have bigger than lubricating oil molecular weight. So as to prevent oxidation process-lubricating oils are provided with antioxidant additives. On the other hand mechanical breakdown of high molecular substances in diesel engine bearings and gas oil leakages cause lubricating oil viscosity drop. The test results presented in the paper show that the lubricating oil viscosity during its operation in the internal combustion engines decreases. The value of viscosity decrease depends mainly on the motor's technical condition, the amount of oil in lube oil system, mode of ignition and its operation. Viscosity tests were performed for the lubricating systems of different engines on a Haake III Mars rheometer at 90 C for variable shear rates. Additionally, in order to determine engine condition, the detail analysis of the tested oil chemical content has been made oil using Spectrol Q100 spectrometer. In the most cases, the research results indicate lubricating oils viscosity decrease and it is possible to determine the relationship between the dynamic viscosity changes and shear rates for the particular engines. In authors opinion the viscosity drop of the tested modern lubricating oils may be caused by better antioxidant additives, which effectively moderate or even prevent the oxidation process. Lubricating oils viscosity drop is dangerous phenomena due to the lowering of the bearings capacity force and possibility of boundary friction.

The problem of lubricating oil consumption still seems to be important one at least because of the use of DPFs in exhaust systems of diesels. Even a minor consumption can be a source of particulate matter that blocksfilters. On the other hand formation of oil film parameters that guarantee minimum oil consumption could lead to the increased friction losses. Ali these remarks relate to the nominal temperature ofoperation. Situation can differ at temperature of cold start. Presented paper deals the problem of oil consumption at lower temperatures. The observation concerning friction losses under these conditions are mentioned as well. Parameters influencing the lubricating oil consumption, oil consumption at nominal temperature of engine run, oil consumption at low temperature are presented in the paper. As well course of oil film thickness, layer thickness and friction force for upper compression ring at engine nominal temperature of operation, course of oil film thickness, layer thickness and friction force for upper compression ring at lower engine run temperature, ring face wetting level at nominal temperature of operation, ring face wetting level at lower temperature of operation, lubricating oil consumption and friction losses generated by ring pack of single cylinder are subject of the paper.
