When burning CNG, the ECU of sequential injection system will get the time of fuel injection in order to calculate how to control the opening time of injector. Engine system is mainly based on ECU to work.

Sequential injection kit is 2 stages decompression which can supply gas required by engine under any conditions and adjust the 2nd stage pressure at the same time. The 2nd stage pressure can be adjusted at random between 1.5-2.6bar. The kit is fit to engines with power of 145KW.
