Methane CNG Sequential Injection System Conversion kits for 3 or 4Cylinder EFI gasoline Cars

Methane CNG Sequential Injection System Conversion kits for 3 or 4Cylinder EFI gasoline Cars


Methane CNG Multipoint Sequential Injection System Conversion kits, for 3 or 4cylinder EFI petrol Cars   RFQ

With this system installed, the car will run on either petrol or CNG, it's bi-fuel system, you can switch between both fuels.

CNG Sequential Reducer/Regulator, integrated with CNG high pressure Solenoid Valve
2. CNG Pressure Gauge
3. Gas ECU set, include: Electronic control unit, Harness, Water Temperature Sensor, Micro-switch, Map Sensor.
ECU Programming software: Mach Pro, support 11 languages--1) English 2) Chinese 3)Polish 4) Russian 5) Thai 6) Turkish 7) Spanish 8) French 9) German 10) Dutch 11) Italian;
It is for 3/4cyls, not for 5/6/8cyls (another type);
Injector Rail-4cyls, 3cyls available;
Gas Filter: Installed after regualtor before injection rail, to filter the low pressure CNG
6. High pressure steel tubingDia 6mm* length 6m 
7. Low Pressure Hoses
8. Mounting Fittings: Hardware etc. for connecting/fixing/sealing the autogas kits on car
9. Programming interface cable--At least 1unit is needed for new buyers, not necessary to buy if you had one yet; For ECU connect to computer to calibrate/program to reach a proper air-fuel ratio for cars of different power, It is special, other ones may not suit to our system.
10. Not Include Items here:
CNG tank, tank valvefilling valve, tank brackets(Too heavy to ship or may not suit to your local requirements) 


How to install the Methane CNG system gas Conversion kits in cars?
Please download Installation manuals and software via "Tech Support" or contact LGC:

How to use LGC's Products? Easiest and fastest way to start from Zero (Take 4cyliner CNG injection system for example):
1. Check visualized installation diagrams from LGC to have a general view of how is the full system connected together
2. Check 4Cylinder Gas ECU wiring diagram for the system to see how is the electronics wired
3. See Installation pictures for reference
4. Study the installation manuals: “LPG CNG Sequential injection system kits installation manual.pdf”, “Mach Pro ECU Programming Guidance.pdf”.
To see how to program the Gas ECU--mainly to reach a proper air-fuel ratio for cars of different power

5. Start your conversion on a car and contact LGC for guidance if questions during installation.
(Installation of other gas systems from LGC: take the above steps as reference.)

Propane and methane system (LPG CNG System) gas conversion kits from LGC:
Sequential injection system kits, two types: suit to 3-4 and 5-6-8 cylinders injection cars;
Propane Methane Normal Suction system Conversion kits suit to 4/5/6/8 cylinders injection cars, EFI as well as carburetor engines;; Mainly for cars older than 1990's, for newer cars, we recommend injection system, better performance;
Do not suit to FSI(fuel straight injection) engines, nor diesel engines either.
