The 4 Cyl 3Ohm CNG LPG gas fuel injector rail is a vital core part for multipoint electronically controlled autogas sequential injection systems, widely used for car gas conversion in Latin America, Brazil, Argentina, Peru, Colombia and other South American markets. Composed of solenoid assembly, valve nozzles and rail body, this 4-cylinder injector rail features nozzles quantity matching exactly the engine cylinder number. Responding in real-time to engine demands and gas ECU commands, it delivers fast, precise gaseous fuel delivery into each cylinder. Compact small-footprint construction brings low-noise operation and highly stable injection flow rate. Built-in stainless-steel internal magnetic tube offers outstanding anti-friction performance. Easy-to-disassemble and easy-to-clean design simplifies regular maintenance for talleres de conversion de gas automotriz. It continuously adjusts gas supply according to variable engine working conditions, compatible with most popular 4-cylinder vehicles for LPG y CNG retrofit projects across South America.

Frequently Asked Questions
Q: What vehicles fit this 4 Cyl 3Ohm gas injector rail?
A: Designed for 4-cylinder gasoline vehicles converted to CNG (GNV) or LPG(GLP) sequential injection kit. The 3Ohm coil version is mainly recommended for Compressed Natural Gas systems popular in South America.
Q: What is difference between 2Ohm and 3Ohm injector rail?
A: 2Ohm coil is optimized for LPG(GLP), while 3Ohm coil matches CNG(GNV). Opening-time and turn-off-time parameters differ, you need select correct resistance for your autogas ECU.
Q: Is this injector rail suitable for taxi fleet conversion projects in Latin America?
A: Yes, this unit is widely supplied for talleres de conversion de gas automotriz for taxi and fleet retrofits across Brazil, Peru, Argentina, Colombia and Chile.
Q: Can I clean this injector rail when suffering clogged nozzles?
A: Yes, it adopts easy-to-clean construction. Regular cleaning helps to recover stable gas flow and avoid rough idling or high gas consumption problems.
Q: What will happen if injector rail performance degrades?
A: Clogged or worn injectors can lead to unstable idle, power loss, higher gas consumption, misfire and poor performance for vehiculos a gas natural.
Q: Can I combine this injector rail with other CNG LPG spare parts for one shipment?
A: Yes, you can mix-order with reducer, filter, pressure gauge, ECU harness and other autogas accessories for consolidated export shipment.
