Lubricant control
 Embodiments of lubricating systems and methods for two cycle, crankcase compression, diesel engines wherein certain running components of the engine such as the crankshaft and pistons are each supplied with their own lubricating systems including independently operating lubricating pumps, each system is controlled so as to supply a finite amount of lubricant to the engine and then sense the engine running conditions to determine when the lubricant will have been consumed before additional lubricant is supplied. In addition, a control routine and structure is disclosed wherein lubrication is supplied to the engine before starting is initiated and wherein the amount of lubrication supplied is varied during break-in.
