The flameout that flameout breakdown includes automatic flameout, intermittence flameout, exterior condition to cause (quickly flameout of flameout, apply the brake, open air conditioning flameout, put into gear flameout) and cannot flameout 4 kinds big.
(one) the common cause of breakdown
1, leak of vacuum of road of air inlet duct.
2, connect of fuel supply system has leak.
3, idle fast adjust undeserved.
4, job of dynamoelectric gasoline pump is bad. For example brush is excessive wear away or the contact is undesirable, or fuel pump mesh jams etc.
5, block of valve of waste gas recycle or bottom leak.
6, fuel injector has trouble. Fuel injector jams or get stuck dead for example, or control circuit has trouble.
7, cold starting fuel injector has trouble. The flameout after starting for example.
8, gasoline pump relay has trouble.
9, ignition department job is bad. Do not have high-pressured fire for example, sparkplug use time is too long, ignition when incorrect, the existence when ignition coil contacts undesirable or hot condition is v/LIT all over the ground short circuit is brought about do not have high pressure or high-pressured scintilla is weak etc.
10, circuit breakdown. If contact attaint of glue of undesirable, insulation,wait.
(2) electronic-controlled the reason of the respect
1, body of solar term door is too dirty. Bring about after quickening, loosen when quickening footplate, because do not have idle fast transfer and flameout.
2, idle fast electromotor or control line road have trouble.
3, sensor of position of solar term door has trouble.
4, air flowmeter has trouble. For example, air flowmeter hot line is too dirty; Point of solder of in-house circuit join drops, the contact is undesirable etc.
5, breakdown of inlet pressure sensor. For example sensor vacuum glue provides burst, hourglass is enraged, sometimes not flat, make from time to time of signal of inlet pressure sensor normal, from time to time is abnormal, cause engine to receive the flameout when quickening footplate.
6, sensor of cooling fluid temperature has trouble.
7, oxygen sensor has trouble. For example voltage of oxygen sensor signal is invariant, cause flameout of the engine when quickening easily.
8, crankshaft position sensor has trouble. If do not have rotate speed signal (plug was not inserted good, line of crankshaft position sensor is broken, bolt of sensor fixed position becomes loose, clearance the) such as attaint of maladjusted, sensor; Signal of crankshaft position sensor ages the circle breaks tooth, can cause the flameout when quickening; If stability of temperature of component of the electron inside crankshaft position sensor can be poor, can bring about signal abnormal, can cause intermittent flameout trouble.
9, ECU has trouble.
10, pressure adjuster has trouble.
11, ignition controller or ignition distributor module have trouble.
12, circuit has trouble. Take iron like sensor or ECU undesirable etc.
(3) cannot the reason of flameout
1, common cause
(1) engine temperature is exorbitant.
(2) waste gas recycle a powerful person works abnormal or cannot open.
(3) idle fast exorbitant.
(4) firebox carbon deposit is overmuch, or fuel injector has trouble.
(5) sparkplug choice is incorrect.
2, electronic-controlled respect reason
(1) sensor of position of solar term door has trouble.
(2) fuel pressure adjuster has trouble. Be like not sealed or diaphragm attaint
(3) sensor of cooling fluid temperature has trouble.
(4) inlet temperature sensor has trouble.
(5) ECU or connector have trouble
