GUIDE TO REDUCTION OF SMOKE AND ODOR FROM DIESEL-POWERED VEHICLES

SINCE THE AIR-FUEL RATIO HAS A GREATER EFFECT ON SMOKE EMISSIONS FROM DIESEL ENGINES THAN OTHER FACTORS, ANYTHING THAT TENDS TO REDUCE THIS RATIO, SUCH AS EXCESS FUEL OR INSUFFICIENT AIR, WILL LEAD TO MORE SMOKE AND SHOULD BE AVOIDED. ENGINE DERATING, THE METHOD USUALLY EMPLOYED TO REDUCE SMOKE, IS RECOMMENDED AND SHOULD BE CONSIDERED GOOD PROCUREMENT POLICY. VEHICLE AND ENGINE MAINTENANCE PROGRAMS MUST INCLUDE A CONTINUING CAMPAIGN AGAINST FAULTY FUEL INJECTORS, RESTRICTED AIR CLEANERS, AND INCORRECT ADJUSTMENT OF INJECTORS. TURBOCHARGING CAN BE USED TO MINIMIZE VISIBLE SMOKE DURING OPERATION AT HIGH ELEVATIONS. DRIVERS SHOULD DEVELOP THOSE DRIVING HABITS THAT ARE KNOWN TO MINIMIZE ODOR AND SMOKE EMISSIONS. DRIVERS SHOULD AVOID EXCESSIVE ENGINE IDLE AND UNDERSPEEDING (LUGGING). THE LOCATION AND DIRECTION OF THE VEHICLE EXHAUST STACK OR PIPE CAN MAKE A SIGNIFICANT DIFFERENCE IN THE NOTICEABLE AND POTENTIALLY OBJECTIONALBE ASPECTS OF SMOKE AND ODOR. /AUTHOR/
