Analysis of the Influence of Fuel on Oil Charge and Engine Wear

Abstract

The combustion engine is a very widespread energy source for many machines and devices. Diesel, gasoline, LPG, CNG, as well as many biofuels such as ethanol, butanol, etc. are used as propellants at the present time. During the running of the internal combustion engine, some fuels penetrate into the crankcase and degrade the engine oil. This potentially reduces the lubricating ability of the oil and changes its degradation process. Submitted paper follows possible changes in lubricating capabilities of oil used in engines with specific fuels: n-butanol, LPG and diesel. Different type of fuel used in combination with an inappropriate operating mode might have a significant influence on the oil and consequently on the engine wear (monitored by a laser particle analyzer). This paper also deals with presence of various types of particles in the engine oil. Results demonstrate proceeding changes noticed in oil and also how was the degradation process effected.

Modeling of Diesel Engine Fuel Systems Reliability When Operating on Biofuels

“…To increase the service life of fuel systems, it is necessary to replace the sealing materials for engine fuel systems made of natural or synthetic rubber with fluoroplastics. This will increase the reliability of the engine as a whole by 3-4 times [44,45].…”

“…As a result of the analysis of possible theoretical and experimental ways to study the increase in the reliability of diesel engines when operating on bio-diesel fuel, two main methodological directions have been established. The first includes design and technological methods that require changes in the design parameters of precision joints and improvement in the manufacturing technology of individual parts [45,46]. The second is operational and technological methods associated with ensuring favorable operating conditions for rubbing parts by improving the existing repair and maintenance technology [47,48].…”

The Effects of Biodiesel on NOx Emissions for Automotive Transport

“…Developing promising methods to reduce the environmental impact of the road transport on environment [1][2][3][4][5][6][7], scientists are making great efforts to ensure that transport is "green". Automobiles using diesel fuel have large harmful emissions of nitrogen oxides and soot, which affect the health of the population and especially children and carbon dioxide, which is dangerous for the planet as a whole.…”
