喷油嘴油压（Nozzle pressure） Automotive engine maintenance and troubleshooting br Abstract: the engine is the core part of the car and is prone to malfunction. In this paper, it is analyzed that the spark plug is prone to br fault and its usage taboo. Several common troubles and troubleshooting methods of the automobile engine are introduced. br engine is the heart of the car. It is important to maintain the engine for the normal operation of the br car. br1 spark plug maintenance br spark plug is br engine ignition system fault more components, many aspects of the use and maintenance of the spark plugs, etc. if there is a choice or sparse br suddenly play are improper, will affect the normal function of the. Spark plug br use maintenance sevenavoid: br1) avoid long-term clean carbon deposit. Spark plug in use, its electrical br pole and skirt insulation experience carbon deposition, if not clean for a long time, br will accumulate more, eventually lead to electrode leakage, not even jump fire. So br should clean up carbon deposits at regular intervals (usually 3 000~5, 000 km) and dont clean when the br spark plug doesnt work. br2) avoid long-term use. The spark plug has an economic life, and if it is still used after more than br economic life, it will be detrimental to the dynamic performance of the engine and the br economy. Research shows that, with the spark plug br long period extended, the center electrode surface will change, to the arc shape side electrode to br concave arc shape change, will make the electrode gap increases, and cause discharge (i.e. br sparks) difficulties, affecting the normal work of the engine. br3) avoid scaling at will. Some people in the engine spray or other maintenance silver br, do not pay attention to the spark plug of clean appearance, resulting in fire br smudgy and leakage appearance. Attention should be paid to descaling the spark plugs. In addition to the br scale, do not use sandpaper, sheet metal, and the spark plug into br ga
