Abstract
【解決手段】エンジンを(a)相対的に多量の潤滑粘度の油および(b)相対的に少量の天然ガスエンジン油添加剤パッケージを含む潤滑油組成物で潤滑する。ただし、潤滑油組成物は実質的に亜鉛化合物並びにアルキレンポリアミン、アルデヒド、および置換フェノールの縮合生成物のアルカリ土類金属塩のいずれも含まない。
【選択図】なし
Description
製造した潤滑油組成物は、ビスコハク酸イミド(1300MWのポリイソブテニルコハク酸無水物(PIBSA)から誘導される)および重ポリアミンとジエチレントリアミンとの混合物を3.3質量%、カルシウムスルホネート(17BN)0.43質量%、硫化カルシウムフェネート(114BN)3.0質量%、ヒンダードフェノール酸化防止剤0.9質量%、消泡剤5ppmおよびII種基油に属するための調整剤を含むものであった。潤滑油組成物は、ASTM D874で測定して0.46質量%の硫酸灰分量を有していた。
実施例1の潤滑油組成物を一級アルコールから誘導したジアルキルジチオリン酸亜鉛0.38質量%でトップ処理することにより、潤滑油組成物を製造した。潤滑油組成物は、ASTM D874で測定して0.50質量%の硫酸灰分量を有していた。
実施例1および比較例Aの潤滑油組成物について、ワーケシャ社製F11GSIDエンジンにおいて、排気弁座の後退を防止する効果を評価した。この試験では、6気筒のワーケシャ社製F11GSIDエンジンを、12弁(6吸気および6排気弁)から動的電圧が測定できる(例えば、米国特許第4672843号明細書に記載されている)ように設定した。各試験では、90%の負荷において1800rpmで駆動させて、400時間稼働させた。吸気温度を110乃至150°Fの範囲としながら試験の間、化学量論的な条件を維持した。実施例1および比較例Aの潤滑油組成物について弁の後退摩耗速度の平均を、各試験の最後の300時間のデータを基に直線に近似することにより計算し、1000時間当たりの摩耗速度として記録した。排気弁の後退の結果を第1表に示す。この表において、弁の摩耗による後退速度が相対的に遅い場合は、排気弁座の後退の防止効果が相対的に大きいことを意味する。
