31、uction control tests, production tests and inspections shall be in accordance with established commercial practice for the type engine to be supplied. Unless otherwise specified, the equipment shall not be treated to resist fungus and moisture. 3.2.1.2 Commercial indwtrial. The commer- cial industri

32、al diesel engine shall be equiva- lent in design, power and size to the engine normaily furnished by the end item manufac- turer in similar commercial products and shall provide sufficient power and torque to meet the performance and operational re- quirements specified herein. If there is no commer

33、cial counterpart, the engine shall be equivalent in design, size and horsepower to engines furnished in competitive commercial models, The complete system shall be ar- ranged to fit within the existing engine en- closure with no 90“ fittings or traps in the air lines and shall be readily accessible

34、for maintenance. 3.2.2 Engine accessories. Engine accessories shall be as specified herein. 3.2.2.1 Electycal system. The truck shall be provided with a 12-volt starting, lighting and other electrical equipment approved by the bureau or agency concerned. All wires and cables shall he adequately supp

35、orted to mini- mize chafng and provide adequate clearance vibration, cables and wiring shall be pro- tected by flexible tubing or suitably har- nessed. Grommets shall be provided when- ever wiring passes through bulkheads, parti- tions OP structural members, or the wiring shall be suitably fastened

36、to prevent chafing or abrasion. All components of the electrical system shall be weather resistant. 3.2.2.2 Generatw.
