“…The other element, the soluble organic fraction, was found to be reduced by only 13% under cold start and 7% under warm start conditions. Some investigations [11][12][13][14][15][16][17] demonstrated decreases of between 5% and 22% in particulate emissions when using synthetic oil as compared to mineral oil. For example, Manni et al [11] investigated the emissions response of a single-cylinder DI diesel engine using different lubricants.…”

The reduction of harmful pollutant emissions as well as CO 2 emissions emanating from motor vehicles will be of considerable interest in the coming decades. Emissions legislation will be the guiding principle in the development of new technologies and vehicles. More attention will have to be paid to off-road vehicles, especially tractors, if the production of healthy food and the maintenance of a cleaner environment are not to be compromised. Therefore, one the biggest challenges facing the automotive industry is to improve fuel economy, both to conserve natural resources and to limit pollutants and CO 2 emissions. Better fuel efficiency and consequently lower emissions will require new materials, new lubricants and low-emission fuel. Engine lubricants help to improve vehicle efficiency but contribute engine exhaust emissions. This paper deals with the influence of engine lubricants on diesel exhaust emissions. Investigations have shown a clear effect of lubricant oil on emissions, which depends on lube oil characteristics, especially sulfur content, metal content, volatility and density.

“…52 In addition, there has been more research carried out by other authors in this regard. [53][54][55] Influence of lubricating oil. Just as the lubricating oil influences deposits in diesel engines, so does lubricating oil influence the formation of deposits in gasoline engines, and much research similar to the methods of Diaby et al 23 was made to verify the influence of lubricating oil on deposits in gasoline engines.…”

“…Just as the lubricating oil influences deposits in diesel engines, so does lubricating oil influence the formation of deposits in gasoline engines, and much research similar to the methods of Diaby et al 23 was made to verify the influence of lubricating oil on deposits in gasoline engines. 53,56 For example, Ahrenfeldt et al generated deposits on a 0.48 l single-cylinder high compression ratio spark ignition (SI) engine fueled by synthetic gas. The results of the experiment indicate that the deposits were possibly derived from the lubricating oil.…”

This article reviews experimental studies on deposits in engine combustion chambers, with emphasis on deposit composition, damage to engines, formation mechanisms and study methods. The existence of combustion chamber deposits will definitely influence performance and emissions of engines, and is inevitable with the use of petroleum fuel and lubricating oil. These all make it necessary to study the formation, composition, structure and influential factors of deposits, which will provide the basis for reducing deposits in engines. Influential factors and methods of reducing deposit formation are also included. First, the deposit damage to engines is briefly introduced, with a focus mainly on the decline in engine performance and the deterioration of emissions, and the reasons for these phenomena are explained. Next, conclusions on deposit research approaches to their chemical composition and physical structure are drawn. Finally, with regards to deposit formation in gasoline and diesel engines, deposit composition and factors influencing deposit formation, such as engine type, fuel type, oil type, additives, exhaust gas recirculation, etc., are enumerated through experimental studies on engines. Studies on deposit formation with some newly developed types of fuel are also included. The mechanism of deposit formation under these different conditions is explained, and the methods for reducing deposit formation are summarized.

U teku}oj dekadi ovog milenijuma proizvo|a~i motora moraju posti}i dvostruko smanjenje potro{nje goriva, pa time i emisije CO 2 i desetostruko smanjenje nivoa emisija, pre svega NO x i ~estica. Za dostizanje tog cilja moraju se razviti nove specifikacije ulja, ~iji doprinos smanjenju potro{nje goriva i nivou {tetnih emisija postaje sve va`niji. Trend razvoja ulja kre}e se u pravcu ni`ih viskoznih gradacija sa ni`im sadr`ajem sumpora, fosfora, sulfatnog pepela i ni`om isparljivo{}u, ~ime se posti`e smanjenje emisije, kao i potro{nje goriva. Klju~ne re~i: motori SUS, motorna ulja, emisije.
