The potential of three micro-organisms (Pseudomonas, Streptococcus and Bacillus sp) were isolated from hydrocarbon contaminated soil and were evaluated for their biodegradation ability. The rate of biodegradation of the engine oil in the soil samples were exposed to used engine oil with different exposure rates of 5,10,15 and 20 years  were studied for a period of three (3) weeks under greenhouse experiment. The soil samples were obtained from four different mechanic workshops in M.M.C and they were plated on nutrients agar and oil agar medium to isolate the bacterial species from the spilled soil samples. All the micro-organisms used in this study showed their abilities to remediate soil exposed to used engine oil and the remediated soil samples were able to support the growth of Maize ( Zea mays) after 10 years  effective growth

The study achieve to make an environmental impact assessment for a spent engine oil recycling plant in AL-Diwaniyah city – Iraq. The assessment has been carried out using Leopold matrix. The studied plant deals with the bentonite clay as adsorbent material for removing the impurities from spent oil. The waste of bentonite clay which has been discharged as by- product waste without any minimal level of remediation which is harmful to the all environmental components in addition to that, the plant discharges air pollutants during the operation. Leopold matrix is a simple method in terms of applying and using, it can be used easily for a comparison among different projects and gives clarified results. Moreover, the significant characteristic is its ability to covering biological, physical, economic and social environment.  From the results of Leopold matrix analysis, it can be observed that the maximum impact of the plant was on physical components in both quantity and importance, while there are some positive impacts on social components. Generally, all the impacts that caused from the plant is low on the environment by the comparison with maximum locally index of environmental impact value.

Study Results

The rate of wear of the cylinder liner is mainly a function of peak cylinder pressure, the depth of penetration of hard carbon particles ingress during abusive running conditions. The problem of wear becomes severe as the blowby past the rings and the oil consumption of an engine increases in diesel engines. In this paper, a methodology is developed to estimate the wear of liner due to bore polishing action. The wear rate is correlated with the product of gaseous load, contact stress, and sliding action of the piston surfaces. Under abnormal conditions, the shear strain due to friction exceeds the plasticity limit of the material, superficial delamination occurs at the liner surfaces. The wear model was validated on large engines running on heavy fuel at 22-bar bmep. The case study results showed that by modifying the piston profile and liner geometry, and bore polishing of the liner surfaces is reduced and the engine oil consumption rate is improved substantially.

This paper presents a case study and a model to predict maintenance interventions based on condition monitoring of diesel engine oil in urban buses by accompanying the evolution of its degradation. Many times, under normal functioning conditions, the properties of the lubricants, based on the intervals that manufacturers recommend for its change, are within normal and safety conditions. Then, if the lubricants’ oil condition is adequately accompanied, until reaching the degradation limits, the intervals of oil replacement can be enlarged, meaning that the buses’ availability increases, as well as their corresponding production time. Based on this assumption, a mathematical model to follow and to manage the oil condition is presented, in order to predict the next intervention with the maximum time between them, which means the maximum availability.
