| 1985-1990 model-year Detroit Diesel Corporation (DDC) 6V92TA DDEC urban bus engines with power ratings of 253 and 277 horsepower | The DDEC Engine Upgrade Kit rebuilds diesel-powered 1985-1990 model-year 6V92TA DDEC urban bus engines to meet California's 1991 model-year heavy-duty diesel urban bus engine emission standards of 0.10 grams per brake-horsepower-hour (g/bhp-hr) particulate matter (PM) and 5.0 g/bhp-hr oxides of nitrogen (NOx). The DDEC Engine Upgrade Kit consists of three kits: 1) engine rebuild kit - newly manufactured parts, 2) engine rebuild kit - reliabilt parts, and 3) converter/muffler kit. The newly manufactured parts kit consists of a gasket kit, air inlet hose, blower drive gear (2.05 to 1), blower by-pass valve assembly, cylinder kits (piston assemblies and cylinder liners), new electronic-unit fuel injectors, and DDEC II to DDEC III conversion kits. The reliabilt parts kit consists of remanufactured camshafts, blower assembly, turbocharger, and head assemblies. The converter/muffler kit consists of a direct-replacement oxidation catalyst supplied by Nelson, Engine Control Systems, or Engelhard. One of each type kit is required for the rebuild of an engine. |
