Major advantage of the present utility model is:
Automatically cleaning is effective, owing to adopting bypass to purge, can, the in the situation that of power-off, carry out automatically cleaning to pipe interior, guarantees that igniter is clean, is easy to igniting.
Cause success rate high, owing to adopting Hi-mixer, use automobile just can control ignition with spark plug, use high-energy igniter economical and practical than in the past.
Cause energy large, because mixture homogeneity improves, under the constant prerequisite of other condition, more fuel saving gas, the bursting strength of gaseous mixture is also higher.
Failure rate is low, anti-backfire are effective, have used two acetylene non-return valves in acetylene pipeline, and two two-way to dress acetylene magnetic valve, and spark arrester, shares non-return valve four road anti-backfire measures.
On-the-spot easy for installation, easy to maintenance.
