Engine Resolves Power, Emissions Questions

摘要

Sometimes a fleet manager just needs more power in the fleet's trucks. The terrain may be demanding. Or you may want to pull pup trailers with your dump trucks. Or maybe you just want more torque. And yet engines are changing. New federal rules are forcing truck and engine manufacturers to reconfigure their products to meet ever-tougher exhaust emission standards. New standards took effect in October 2002, and they will only get more demanding in the future. One answer to the need for higher horsepower―in a truck-engine combination that meets EPA's Tier 2 standards―is the new series of International 5000i trucks fitted with Cummins ISM 425V engines. These new 11-liter engines pump out 425 hp and 1550 pounds-feet of torque―and are several hundred pounds lighter than other big-bore engines, says Chuck Goode, Cummins' director of national accounts for vocational markets.
