ECOLOGY OF USED ENGINE OIL ADDINOL

2023
Comprehensive spectroscopic studies of used and regenerated with chloric acid samples of ADDINOL engine oil were carried out. It was revealed that during the operation of engine oil, structural changes in hydrocarbon components, the formation of oxygen-containing compounds, and the accumulation of products of thermal destruction and friction occur.

Reclamation of Used Engine Oil

Journal of the Chinese Chemical Society, 2002
AbstractUsed lubricating oil from vehicles was treated with various types of chemicals to be regenerated. It was found that used lubricating oil could be reclaimed with sulphuric acid, sodium hydroxide, sodium phosphate, ammonium sulphate and rosin.

Experimental Investigation on Diesel Engine Using Processed Waste Engine Oil

Applied Mechanics and Materials, 2014
An experimental investigation on the performance, emission and combustion characteristics of single cylinder water cooled diesel test engine was carried out at a constant speed of 1500 rpm with processed waste engine oil. The experiments were carried out at different load conditions from no load to 110% load.

Engine Oils For Use With Alternate Fuels

SAE Technical Paper Series, 1984
<div class="htmlview paragraph">Alternate fuels may be required to supplement future gasoline and diesel fuel supplies in spite of today's temporary excess of crude oil. A decade of lead time may be required to successfully bring these alternate fuels to the market place.

Analysis of Used Lubricant Engine Oil: SAE20W50

Advanced Materials Research, 2011
As a result of the changes that occurs the lubricant oil during their use, aged engine oils tend to differ in chemical and physical composition from virgin oil. We have chosen for study theses variations (changes) the oil that is the most sell in Algeria for cars with engine gasoline. For this investigation the oil was examined at different kilometres.

Monitoring of Gas Turbine Engine-Used Oil

SAE Technical Paper Series, 1987
<div class="htmlview paragraph">Gas Turbine engine manufacturers recommend an oil change if such properties as viscosity, acidity, etc, of the oil in use, exceed certain values. Since increases in the properties mentioned indicate the lubricant to be undergoing thermo-oxidative stress, the advice appears sound.

The lubricating properties of used engine oil

Wear, 1982
Abstract The lubricating properties of oil samples from four cars using either leaded or unleaded gasolene were examined using a cross-pin-type lubricant tester and a JIS four-ball tester. The zinc dialkyldithiophosphate (ZnDTP) content in the oil samples was determined by thin layer chromatography (TLC). The wear scar diameter increased with running

Improving the Environmental Safety of Transport Engines Using Modified Engine Oil

Ecology and Industry of Russia, 2020
The problems of reducing emissions of harmful substances by transport engines are considered. It has been established that the use of modified engine oil is an effective way to increase the environmental safety of transport engines. The effectiveness of additives to improve the backsize of motor oil and reduce harmful emissions in the exhaust gas was ...
