Title:
潤滑油用の過塩基性清浄剤
Document Type and Number:
Japanese Patent JP4974458
Kind Code:
B2
Abstract:
The present invention provides overbased detergents as lubricating oil additives effective for the lubrication of mechanical components in land and marine engines, such as, for example, hydraulic systems, transmissions, two-stroke and four-stroke vehicular engines, trunk piston and two-stroke crosshead marine engines. These overbased detergents lead to improved detergency and thermal stability performances versus high overbased sulfonates. Moreover, they are more compatible with commercial phenates than conventional sulfonates.
