New Year new atmosphere, new Year first phase, we learn to learn to build a car together. This repairs Che Zhen to must learn two trick, you think, everybody is protected forbid when He De, this car " bends over " " nest " , if you understand little common sense, give love car " of nutrition of a bit " immediately went up road, this saved how old trouble. Let us learn to learn how to listen to abnormal knocking to judge breakdown together now. Car abnormal knocking is commonner breakdown, you often may admire old driver master to be able to rely on car abnormal knocking to judge breakdown a pretty close. Actually, want you to notice to be accumulated observation, frequently only, think more, understand its expression and feature, also can comprehend among them secret certainly.
When the car works, each system shakes the sound a general designation that give out to be the noise of the car, say again on some books for noise. And these noise can be divided again it is normal to be normal sound and blame noise 熞 illuminate a lot of breakdown of car of F of yo of exhaust of Yu 犃 sauce come out through abnormal knocking expression, abnormal knocking is a phenomenon, breakdown just is substaintial. If remove trouble not in time,cause great and mechanical accident extremely easily.
Common abnormal knocking basically can divide the car to fasten abnormal knocking, travel to fasten abnormal knocking, wind block abnormal knocking to wait for a few kinds big for dynamical assembly abnormal knocking, drive.
Dynamical assembly abnormal knocking
Breakdown basically appears in engine to mix its are relevant component, abnormal knocking follows engine rotate speed and change, and frequency is taller.
１ . Engine breaks a crock to lack fire. This kind of abnormal knocking is better identify, abnormal knocking accompanies engine to shake strongly, and sound frequency and shake frequency is same. If encounter this kind of situation, not flurried, nearby looks for a service station to check engine to supply oily, ignition, air feed and engine computer, remove trouble can.
2. Engine is lubricant systematic work efficiency drops cause works excessive attrition. Perhaps be long-term do not do oil change to maintain the invalidation of metamorphism of engine lubricating oil that cause, sealing of lubricant perhaps department drops the engine oil pressure that cause is insufficient, can make engine lubricant the effect drops, cause clash excessive attaint produces abnormal knocking. Of this kind of mechanical abnormal knocking shake frequency and engine rotate speed (incentive frequency) have immediate concern, regular job rotate speed is in engine 800 - ｎ of ｉ of ｍ of 5000 ｒ ／ . The frequency that produces noise is very tall, person ear can hear the sound with successive or discontinuous very short time only, lift as engine rotate speed, abnormal knocking increases subsequently on volume and frequency. If your love car appeared afore-mentioned different shape, be about to did good psychology to prepare, most at least is disintegrate examination wear out condition is repaired in engine.
