东方红—28拖拉机安装沈阳东方红2125、2125A两种柴油机。东方红2125柴油机标定功率为28马力,标定转速为1400转/分,采用大连油泵油嘴厂BHF2T85YR04、东北油泵油嘴厂2 BII90Y、和沈阳机油泵厂IB 2 Y85×7 J型喷油泵;东方红2125A柴油机标定功率为30马力,标定转速为1500转/分,采用大连油泵油嘴厂和锦县农机修造厂Ⅰ号泵。同一型号的拖拉机常安装不同型号的柴油机;同一型号的柴油机又常采用不同型号的喷油泵。并且,尽管喷油泵的型号完全相同,由于生产厂或出厂时间不同,调试参数也不
Dongfanghong -28 Tractor Shenyang Dongfanghong 2125,2125A installation of two diesel engines. Dongfanghong 2125 diesel engine calibration power of 28 horsepower, the calibration speed of 1400 rev / min, the use of Dalian Oil Pumps Factory BHF2T85YR04, Northeast Oil Pump Factory 2 BII90Y, and Shenyang Oil Pump Factory IB 2 Y85 × 7 J-type fuel injection pump; Diesel engine rated power of 30 horsepower, calibration speed of 1500 rev / min, the use of Dalian Pump Factory and Jinxian agricultural machinery factory No. Ⅰ pump. The same type of tractor often install different types of diesel engines; the same type of diesel engine and often use different types of fuel injection pump. And, despite the exact same type of fuel pump, due to different manufacturing plant or factory, the debugging parameters are not
