3116 (9GK) Truck EnginesSUPPLEMENT: 09/01/94Truck Engine News, August 1994, Page 1, "Changes To 3116 Truck Engine For 1994"In the last line of the chart "Catalytic Converters For 1994 3116 Truck Engines", the part number 117-3165 is NOT correct. The correct part number is 117-3163.
--------------- END SUPPLEMENT ---------------New Ratings
215 hp at 2600 rpm (550 lb-ft peak torque)
This rating provides lower heat rejection for use with an Allison transmission. The current 215 hp rating will continue to be offered.
230 hp at 2600 rpm (650 lb-ft peak torque)
This is a new rating.
Emission Changes
A significant reduction in particulate emissions of 1994 occurred through several changes in the engine. Production of particulates is being reduced through increased injection pressures and a piston bowl shape that burns fuel more efficiently. Piston ring changes reduce oil consumption and exhaust particulates. "Hardened" governor and linkage parts help prevent increased emissions as these components wear. Catalytic converters are used on most engines.
