摘要:
A crankcase lubricating oil composition for slow speed marine diesel engines characterized by having a Total Base Number from about 3 to 10 containing a mineral lubricating oil, an overbased calcium alkylphenolate, a zinc dihydrocarbyl dithiophosphate, an ethoxylated alkylphenol, and a friction reducing amount of at least one acyl glycine oxazoline derivative.
摘要:
A cylinder lubricating oil composition characterized by having a Total Base Number from about 50 to 100 comprising a mineral lubricating oil, from 10 to 20 percent of an overbased calcium sulfonate and at least one acyl glycine oxazoline derivative having the formula: ##STR1## where R is lauryl, C.sub.11 H.sub.23, oleyl or stearyl; and R' is hydrogen or lower alkyl.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a wear-inhibiting additive, a quaternary ammonium reaction product of dilauryl phosphate and a t-alkyl monoamide of iminodiacetic acid.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a corrosion inhibitor, a reaction product of aminotetrazole, formaldehyde, and an N-alkyl propylene diamine.
摘要:
A novel fuel composition contains ethanol or gasohol plus, as a corrosion inhibitor, a reaction product of an aminotriazole, isatoic anhydride and an N-alkyl propylene diamine.
摘要:
A diesel lubricant composition comprising a lubrication oil base and a corrosion-inhibiting amount of at least one benzotriazole, N-alkyl-1,3-propanediamine and formaldehyde condensation product.
摘要:
Lubricant oil comprising a hydrocarbon oil of lubricating viscosity, a sulfurized overbased calcium alkylphenolate detergent-inhibitor having a calcium metal to alkylphenol ratio of at least 2.9:2; and a sulfurized naphthenic base oil-contaning composition having a sulfur content of from 1 percent to 6 percent by weight.
摘要:
Lubricant oil comprising a hydrocarbon oil of lubricating viscosity, a highly overbased alkaline earth metal-containing alkylphenolate detergent-dispersant composition sufficient to impart a total base number to said lubricant oil of at least 10; and a chlorinated sulfurized alkylphenol.
摘要:
A method has been developed to solubilize hydroxy S-triazines containing at least one hydroxy function in diesel fuel and to enhance their overall thermal stability. The products which result from the full or partial encapsulation of hydroxy-S-triazine with calix[8]arene have unique and novel properties and reduce or eliminate nitrogen oxides level in diesel fuel.
