Abstract

En smereoljesejimensetnlng er beskrevet som er nyttig l motorer oed Indre forbrenning og som utviser forbedret oksidasjon og siltesjejteevne. SaereolJesaomensetnlnger er beskrevet son spesielt omfatter (A) en hovedmengde olje ned smerevlskosltet; (B) minst omtrent 1,0 vekt-* av minst en karboksyllsk derlvatEammeneetnlng fremstilt ved omsetning av (B-l) minst ett substituert succlnlsk acylerlngsmlddel med (B-2) minst en amlnforblndelse kjennetegnet ved tilstedeværelse Innenfor denne struktur av minst en HK<-gruppe der nevnte substituerte succlnlske acylerlngsmldler består av substltuent- grupper og succlnlske grupper der substltuentgruppene er avledet fra polyalken, Idet nevnte polyalken er kjennetegnet ved en Mn-verdl på l 300 til omtrent 5 000 og en Mv/Mn-verdl på omtrent 1,5 til omtrent 4,5, Idet nevnte ecylerlngsmldler er kjennetegnet ved tilstede- værelse Innenfor deres struktur av et gjennomsnitt på minst 1,3 succlnlske grupper for hver ekvlvalentvekt av substltuentgruppene; og (C) minst en manganforblndelse l et mengde som er tilstrekkelig for å tilveiebringe fra l til omtrent 500 ppm mangan som metall, forutsatt at manganforblndelsen Ikke er et noytralt mangan- dlhydrokarbylfosfordltloat. 01Jesammensetnlngene kan også Inneholde andre enskellge tiIsetnlngsstoffer, Inkludert (D) minst ett metall- dlhydrokarbylfosfordltloat; (E) detergenteffektlve mengder av minst ett noytrelt eller basisk alkall- mctallsalt av en sulfonsyre eller karboksylsyre; og/eller (F) minst ett karboksyllsk esterderlvat er definert heri. I en utferelsesform Inneholder olJesammensetnlngene Ifelge foreliggende oppfinnelse, ovennevnte tll- setnlngsstoffer og andre tllsetnlngsstoffer l en mengde som er tilstrekkelig for å mullggjere at oljen opp- fyller alle yteevnexravene til "AP1 Service Classl- flcatlon" Identifisert som "SG".A lubricating oil seeding system is described which is useful in engines of internal combustion and which exhibits improved oxidation and silt seeding ability. Particular oil compositions are disclosed which in particular comprise (A) a major amount of oil down the lubrication coil; (B) at least about 1.0% by weight of at least one carboxylic derivative Compound prepared by reacting (B1) at least one substituted succinic acylating agent with (B-2) at least one amine compound characterized by presence within this structure of at least one HK <group wherein said substituted succinic acylating agent consists of substituent groups and succinic groups wherein the substituent groups are derived from the polyalk, said polyalkene having an Mn value of about 300 to about 5,000 and an Mv / Mn value of about 1.5 to about 4.5, wherein said ecylation agents are characterized by the presence within their structure of an average of at least 1.3 succinic groups for each equivalent weight of the substituent groups; and (C) at least one manganese compound in an amount sufficient to provide from about 1 to about 500 ppm manganese as metal, provided that the manganese compound is not a neutral manganese hydrocarbyl phosphorus dihydroplate. The compositions may also contain other individual additives, Including (D) at least one metal dihydrocarbyl phosphorus dihydroplate; (E) detergent-effective amounts of at least one neutral or basic alkali metal salt of a sulfonic acid or carboxylic acid; and / or (F) at least one carboxylic ester derivative is defined herein. In one embodiment, the oil compositions According to the present invention, the above compositions and other compositions contain an amount sufficient to cause the oil to meet all the performance requirements of "AP1 Service Class surface" Identified as "SG1".
