What is the risk if engine load is less than the minimum?
If an engine is operated on a load less than the minimum, certain symptoms of high Lubrication oil consumption and oil leaks may be observed. The cylinder temperatures are too low to insure complete burning of all the fuel delivered. A further result is that of abnormal carbon built up on the valves, piston crowns and exhaust ports. Thus the normal service interval of overhauls may be reduced.
