What is the reason why lng engine suddenly shuts down and can't be started again?

1. Too much carbon deposit in throttle, idle motor, air intake and combustion chamber will lead to engine flameout. There are too many carbon deposits and dirt in the air inlet, and the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle air intake, resulting in the mixture being too rich or too lean and the engine unable to start.

Second, due to the poor fuel constant pressure performance and low fuel pressure of the electronic control system, the fuel injection atomization is poor and it is difficult to start.
