5) Fault phenomenon and judgment method
Fault phenomenon: running noise, poor acceleration, can not start (starting difficulty) etc..
General failure: due to the use of inferior fuel,: 1, glial accumulation formed on the insulating layer;
2. Oil pump bushing and armature lock; 3. oil level sensor assembly corrosion.
Repair note: 1. according to the need of engine, electric fuel pump can have different flow, fuel
pump has the same shape, can hold up is not necessarily appropriate, part No. fuel pump repair by
must be with the original agreement, is not allowed to change the wrong; 2. in order to prevent
accidental damage to the fuel pump, please don't run in the dry state; 3. the need to replace the fuel
pump, please pay attention to the fuel tank and pipeline cleaning and replacing fuel filter.
A simple method to measure:
(Remove connector) Digital multimeter to Ohm, two probes are respectively connected fuel pump
two pins, measuring internal resistance, not zero or infinity (i.e. not short circuit, open circuit state).
(Connect the connector) To start the engine into the tubing connected to the fuel gauge, fuel pump,
observe whether work; if it is not running, check the "+" pin if there is power supply voltage; if the
operation, the idle condition, check the fuel pressure is about 260kPa; off the fuel pressure regulator
vacuum tube, whether fuel when the pressure is about 300kPa.
14. The ignition coil
1) installation position
Installed in the engine compartment
2) working principle
Using double-coil cylinder at the same ignition system
3) technical parameters
Room temperature 23
℃
, typical working voltage of 14V, the primary coil current 7A, secondary
output with 50pF load is 38KV - 10%.
