LPG sequential systems are electronically controlled gas feeding systems. The LPG sequential system can be installed in all vehicles with sequential injection system. The system is controlled by an ECU which controls the gas injection sequence and the timing. The LPG is injected through injectors directly into the suction pipes thus obtaining a particularly precise mix to optimise the combustion process. The gas injection timing is attained by assessing the gasoline injection timing of the original gasoline ECU of the vehicle.

Our sequential system is called LPG Dual Sequential System. The Dual Seqential System is new generation sequential system, and this system is incontestable better than ordinary sequential systems. Our system achieves better performance, more LPG economy, and longer service life of the engine by comparison with the ordinary sequential systems.
