Pin: each injector has two pins SM1 and 02. Among them, the foot with SM1 identifies the main relay
The electrical output of 87 pin; another in accordance with 1, 2, 3, 4 cylinder are respectively connected with the
ECU X1-24, X1-62,
X1-61, B60 pin. V1~4 said the first to the fourth fuel injectors.
2) Installation position
One end of the cylinder head intake valve close.
3) Working principle
Injection time of ECU through pulse width to control fuel injector. Current flowing through the injector coil,
producing drag needle
The electromagnetic force, when the electromagnetic force increases to a certain extent, the needle was beginning
to rise, fuel injection process begins, when the current stops
When the needle valve, under the action of the spring, heavy and closed end, fuel injection process.

(2) The allowable fuel
The injector can be used only in accordance with the people's Republic of China national standard GB
17930-1999 "unleaded gasoline for vehicle and the" national environmental protection standards GWKB 1-1999
"standard" harmful substance control of gasoline fuel and provisions, add detergent in gasoline. In particular,
gasoline is stored for long time will go bad. In particular, LPG and gasoline dual fuel engine in a taxi, long-term to
LPG as fuel, gasoline is used for starting, gasoline consumption rarely. But the long-term operation of fuel pump,
fuel tank temperature is high. If gasoline is stored in the car's fuel tank, it is very easy to be oxidized, may cause
injector blockage or damage.
