Negative Effect

It is vitally important for vehicle users that are to study the operating regime that may negative effect to the operation of the engine, to reduce its effect, to maintain the engine's reliability in accordance with the specific operating conditions. Quality of lubrication is one of the main factors that are improving of reliability and operational efficiency for any machinery their spare parts. So this paper presents to optimize of oil change intervals and to determine of wear rating of spare parts by content of metal particles in the internal combustion engine used oil.

Used Vegetable Oil

Biomass derived vegetable oil is a promising alternative fuel for an internal combustion engine. Direct use of vegetable oil has inferior performance with higher emission due to its higher viscous in nature. This can be overcome by transesterification process with its byproduct which is called as used vegetable oil methyl ester. While blending this biodiesel with fossil diesel upto maximum of 30:70, will give the higher performance and lower emission than the fossil diesel alone. In this present study biodiesel in the form of B23 is used in a four stroke water cooled variable compression ratio engine without any modifications. The performance and emission characteristics are studied with different compression ratio and compared with a base line fossil diesel mode operation. This study reveals that the compression ratio of 18 is the optimum in the view of ignition delay, maximum pressure crank angle, exhaust gas temperature and Smoke emission.

The Impact

The results of modeling the impact of oil burning on the condition of the ship forced trunk piston diesel engine when using lubricants with different operating properties. The dependence of wear rate on oil fume, the quality of used lubricants and marine diesel forcing is obtained by modeling wear using the theory of planning experiments. The area of minimal wear has been determined. There has been detected the most efficient waste oil providing favorable conditions for resource-saving operation of the internal combustion engine. It is inferred that reduction of engine oil fume changes the main parameters of its aging. At the same time, the intensity of oil aging in main directions and of engine wear reduce from 0.75 to 2.25 g/(kW∙h), whereas the fume increases. Its further increase is accompanied by an increase in the rate of oil aging and engine wear. The detected "fracture" depending on И( g y) after passing the border g yopt = 2.25-2.5 g/(kW∙h) is stipulated by different ratio of oil exchange in the lubrication system and the ingress of gases into the crankcase. There has been determined the degree of oil burning, at which sludging and lacquer formation of the internal combustion engine is least intense. The smallest carbon deposits on pistons and in the crankcase of the engine can be observed when the diesel engine is operating in the zone of optimal carbonation. Experimentally, the dependence of tribotechnical properties, in particular, wear of insoluble products of oil aging has been detected at different degrees of oil burning. It is revealed that these characteristics also depend on the quality of the used fuels and lubricants and the conditions of formation and turnover of the oil film on the mirror of the cylinder, the thermal effect on it of the engine workflow. The result of simulation is the prediction of resource-saving operation of marine trunk diesel engines by maintaining oil fume at the optimal level.
