Mechanism of Wear Control by the Lubricant in Diesel Engines
At today's low oil consumption rates, high speed diesel engines with chromium-faced rings have experienced corrosive wear problems.
This report defines the alkalinity required to prevent these wear problems; and the appropriate oil drain interval. In addition, the mechanisms of chromium-faced ring wear are identified.
The study is based on three different engine types—direct injection two-cycle (DDA 8V-71TA), direct injection fourcycle (Mack ETAZ 673), and precombustton chamber fourcycle (Caterpillar 1Y73).
