Definitions

  • the present invention relates to a lubricating oil composition for internal combustion engines, particularly for gas engines using gaseous fuel such as natural gas or liquid propane gas.
  • the lubricating oil composition of the present invention is useful in a method of improving the detergency and oxidation stability at elevated temperatures of gas engines.
  • Electric generators and co-generation systems are widely utilized in retail stores or shops and small-scale factories.
  • a variety of engine systems for in-house electric generators and co-generation systems may be utilized.
  • gas engines using gaseous fuel such as natural gas or liquid propane gas (LPG) are widely used because gas engines produce low noise and low atmospheric pollution.
  • LPG liquid propane gas
  • gas engines are designed to bum gaseous fuel at a temperature higher than that used in other internal combustion engines. Furthermore, gas engines have a small-size oil pan. Therefore, gas engines are apt to generate an increased amount of nitrogen oxides (NO x ), and engine oils employed in gas engines are apt to deteriorate in a relatively short period of time. For these reasons, gas engine lubricating oils need high detergency at elevated temperatures and also oxidation stability at elevated temperatures. It is further noted that gas engines are generally used continuously for long periods of time before oil changes occur.
  • NO x nitrogen oxides
  • gas engines are generally used continuously for long periods of time before oil changes occur.
  • lubricating oil compositions for gas engines have high contents of metal-containing detergent and zinc dialkyldithiophosphate.
  • gas engines are generally equipped with exhaust gas processors containing a three-way catalyst to trap nitrogen oxides.
  • Alkali metal- or alkaline earth metal-containing detergents and phosphorus in zinc dialkyldithiophosphates are known to poison the catalyst. So while it is necessary to have enough metal-containing detergent and zinc dialkyldithiophosphate for sufficient detergency and oxidation stability at elevated temperatures, their amounts should not poison the catalyst. Accordingly, it is required to reduce the amounts of metal-containing detergents and zinc dialkyldithiophosphates in lubricating oil compositions for gas engines.
  • Japanese Patent Provisional Publication No.7-126,681 describes a lubricating oil composition preferably employable for gas engines of the heat pump type, which comprises in a base oil, a polyalkenylsuccinimide and/or its borate derivative, a diarylamine, and a hindered phenol.
  • the lubricating oil composition has excellent oxidation resistance to nitrogen oxides.
  • Japanese Patent Provisional Publication No.7-258,678 describes a lubricating oil composition for gas engines which comprises in a base oil (mineral oil, synthetic oil, or their mixture), an alkaline earth metal salicylate, a bis type high molecular weight alkenylsuccinimide or its derivative, zinc dialkyldithiophosphate, and a high molecular weight hindered phenol.
  • Japanese Patent Provisional Publication No.10-219,266 describes a lubricating oil composition preferably employable for gas engines of the heat pump type, which comprises in a base oil, a metal salicylate, an amine oxidation inhibitor, a hindered phenol oxidation inhibitor, and a polyalkenylsuccinimide and/or its derivative.

  • This publication further describes addition of a borated dispersant to the oil composition and addition of a dialkyldithiophosphate of a metal salt to the oil composition.
  • U.S. Patent No. 5,629,272 issued May 13, 1997, to Nakazato et al. describes an engine oil composition which comprises a metal-containing detergent, zinc dithiophosphate, and a boron-containing ashless dispersant dissolved or dispersed in a base oil; characterized by further containing an antiwear agent having an aliphatic amide compound and either a dithiocarbamate compound or an ester derived from a fatty acid and boric acid.
  • the engine oil composition described provides excellent characteristics in antiwear, especially in reducing wear of the valve train system of internal combustion engines.
  • lubricating oil compositions described in the above-identified publications do not reduce the catalyst poisoning of three way catalyst in exhaust gas processors. Others do not satisfy the requirements of the high temperature detergency and high temperature oxidation inhibition of a gas-engine lubricating oil composition. Therefore, there is a need to have a lubricating oil composition having good detergency at elevated temperatures as well as good oxidation stability at elevated temperatures on one hand and, on the other hand, having levels of metal-containing detergents and zinc dialkyldithiophosphates so as to prevent catalyst poisoning.
  • the present invention relates to a lubricating oil composition for internal combustion engines, particularly gas engines utilizing gaseous fuel, such as natural gas or liquid propane gas.

  • the present invention relates to the use of a metal-containing detergent, a boron-containing alkenyl- or alkylsuccinimide, a zinc dialkyldithiophosphate, an oxidation inhibitor, and an ashless dithiocarbamate for improving the detergency and oxidation stability at elevated temperatures in a lubricating oil composition for gas engines comprising a major amount of a base oil of lubricating viscosity and an effective amount of a metal-containing detergent, a boron-containing alkenyl- or alkylsuccinimide, a zinc dialkyldithiophosphate, an oxidation inhibitor, and an ashless dithiocarbamate.
