Q1.Use CNG kit, how about economical effect?
A1, Take Sichuan deyang city installed gold dragon bus for example,(CA4113Z type pressurize engine, length 7.9M,30 seats), whose running route is from deyang city centre to chendu railway station, whole mileage is60.5 kilometer, daily running 242kilometer(twice come and go) which road is in good condition, it was installed our intelligent electrical control CNG kit in year 2004,it is running well use dual-fuel mode, we calculate and compare the two different mode’s economical effect under same running condition. Under dual-fuel mode, running 100km consume 14.59L diesel,9.9M3 Natural gas. Under diesel mode, running 100km consume 26.77. The price for diesel is 3.54RMB/L,for Natural gas is 1.55RMB/M3. The saving cost as following table shows( if the bus was running in high speed road, will get 60% substitution rate, as well as save more cost)

Q2.Use intelligent electric CNG kit to install vehicle, need to change which part of original vehicle?
A2. Use intelligent electric CNG kit to install normal vehicle to CNG dual-fuel vehicle, only need to add two cylinder and one CNG kit, no big change from original vehicle. One CNG kit including ECU, pressure reducer, solenoid valve, distributor, switch , pedal position sensor and wiring etc components
Q3 How does the driver to operate after installation CNG kit?
A3 The driver can through control switch on the operation panel to let the vehicle working in gasoline or gas, very easy and convenient to operate.
Q4For diesel-CNG dual-fuel kit, which elements will affect the substitution rate?
A4 When the diesel vehicle starting, it use diesel fuel, then supply gas or not depend on ECU judge the vehicle load and rev. when load and rev reached set up data, ECU will inform Diesel control unit to limit diesel usage, and start to supply gas. will only supply diesel when vehicle Idle speed. From this we can see, vehicle work situation, running road condition, vehicle situation, and driver’s operation etc will be effect the substitution result.
Q5 For diesel-CNG dual-fuel vehicle, which situation use dual-fuel mode will get the best result?
A5 When vehicle in normal condition, water temperature reach 60℃use dual-fuel mode will get the best result
Q6What is CNG kit’s performance and effect?
A6 Take Sichuan deyang city installed gold dragon bus for example, after installed CNG kits, its performance compare with original one like following: the max torque ≥102%,RPM advanced 200/min,max power ≥98%,max speed ≥96%,improve exhaust emission, FSN≤1.03(International require ≤4.0),substitution rate ≥50%. From Sichuan southern natural gas vehicle testing centre testing result see: engine’s temperature shows normal, especially improve engine too hot problem, as well as low down black smoke release when freely speed up.
Q7 How about safety of intelligent electronic control CNG kit?
A7 This kit use unique electromechanical integration technology, ECU control precision supply fuel. For turbocharged diesel, CNG fuel mixed with pressurized atmosphere, without backfire, the vehicle running steady, safe and reliable after install our CNG kit..
Q8 which type of vehicle available for intelligent electric control CNG kit?
A8 Since our intelligent electric control CNG kit’s key technical is high-tech, common use ECU, it is available for variety vehicles(Gasoline car, diesel truck) as well as variety fuel(LNG,LPG, CBG, methane).
