喷油泵工作的好坏,直接影响发动机的功率。为保证发动机正常工作,使用一段时间后,都要在试验台上对喷油泵进行调试。然而,有的喷油泵经过调试后,发动机的功率还是不足,经分析有以下情况: 一、试验台附件对供油量的影响经调试后的喷油泵,在马力试验中常出现供油少、发动机功率不足的现象。主要原因是,在试验台上校正时,所使用的附件如输油泵、滤清器、喷油器、油管与回油阀等的技术状态与原实际机车的技术状 Fuel pump work is good or bad, a direct impact on engine power. In order to ensure the normal operation of the engine, after a period of time, must be in the test bench on the injection pump debugging. However, some pump after debugging, the engine power is still insufficient, the analysis of the following conditions: First, the impact of the test bench attachment on the fuel supply After debugging the fuel pump, often in the horsepower test less fuel, the engine Power shortage phenomenon. The main reason for this is that the technical conditions of accessories such as oil pumps, filters, injectors, oil pipes and oil return valves used in the calibration of the test rig are similar to those of the actual locomotive
