NEW DIESELS MEAN NEW DEMANDS ON OIL, FUEL

The Environmental Protection Agency's heavy duty diesel exhaust standards in January 1991 are discussed. To cut down particulates and oxides of nitrogen, diesel engine builders are making internal changes that will significantly impact engine lube oils because otherwise much of the soot that used to go out the exhaust pipe will end up in the crankcase. The new engines, it is expected, will need much less make-up oil, and retarded engine timing, high-pressure fuel injection and piston ring changes will all increase the load put on crankcase oils. The '91-model diesel truck engine's combustion technology is discussed, as well as field test programs.
