43、 engine is a Mack E7-350 mechanicallygoverned engine, P/N 11GBA77623 (see Annex A5). It is anopen-chamber, in-line, six-cylinder, four-stroke, turbocharged,charge air-cooled, compression ignition engine. The bore andstroke are 124 by 165 mm (478 by 612 in.), and the displace-ment is 12 L (728 in.3).

44、 The engine is rated at 261 kW (350bhp) at 1800 r/min governed speed (see SAE J1995).6.1.2 The ambient laboratory atmosphere should be rela-tively free of dirt, dust, and other contaminants as required bygood laboratory standards. Additionally, it is recommendedthat the atmosphere in the engine buil

45、dup area be filtered andcontrolled for temperature and humidity to prevent accumula-tion of dirt or dust on engine parts. Uniform temperaturecontrol will also aid in measuring and selecting parts forassembly.6.1.3 Use the low sulfur reference diesel fuel shown inTable 1.6.2 The Test Engine:6.2.1 Mac

The No. 6 and No. 8 Aeroquip5lines should haveinside diameters of 10 mm (38 in.) and 13 mm (12 in.),respectively. The vent line size is specified as a minimum No.8 line size. Equivalent lines may be substituted for Aeroquiplines provided they have the proper inside diameters.6.2.5 Crankcase Aspir
