1.反弹法测气缸压缩力气缸压缩力是保证柴油机压缩升温、自然着火的关键。压缩力是否充足,可通过压缩力反弹法检测。方法:在柴油机不减压的情况下,试摇发动机,当摇转到某一角度时,觉得阻力很大,此时若放松摇把(手不离摇把),摇把有较大的回转力,表明发动机压缩力良好;反之,压缩力不好。2.密封法检查出油阀性能油阀性能(1)密封性检查将高压油管接到喷油泵上,使其充满柴油,油门置于停油位置,使油管出口水平,不转曲轴,观察油管液面,高度不变,出油阀密封良好;否则,出油密封性能变差。也可将油
1. Rebound method to determine cylinder compression force Cylinder compression force is to ensure that the compression of diesel engines, the key to natural fire. Compression force is sufficient, by compressive force rebound test. Methods: In the case of diesel engine without decompression, try to shake the engine, when the pan to a certain point of view, that resistance is very large, then relax the crank handle (hand from the crank), the crank has a greater turning force , Indicating that the engine compression is good; the other hand, compression is not good. 2. Sealing method to check the performance of the valve performance valve performance (1) tightness check the high-pressure tubing connected to the injection pump, so that it is full of diesel, the throttle is placed in the stop position, so that the level of export tubing, do not turn the crankshaft, observe the tubing Liquid level, the same height, a good valve seal; otherwise, the oil seal performance deterioration. You can also oil
