16 W Allowable fuel:
The injector can only use the fuel in compliance with the provisions in GB 17930-1999 (for vehicle unleaded gasoline) and GWKB 1-1999 (harmful substance control standard for vehicle gasoline), and detergent is required to be added into gasoline. It should be specially pointed out that too long storage of gasoline may make it deteriorate. Especially, the taxi with a (LPG and gasoline) dual-fuel engine uses LPG as fuel long and gasoline is only used for startup, so, daily consumption of gasoline is little. However, because the fuel pump runs long, so the temperature of fuel tank is quite high. If gasoline is stored in the fuel tank of such auto, it may quite liable to oxidation and deterioration, which may lead to choke even damage of injector. 9.4 Installation attentions 1. O-ring 2.
