    Abstract: Phenomenon of Backfire in intake pipe is common and inevitable while gas engine is in operation.  Serious backfire may damage the inter-cooler or crack intake pipes. Conventional measure to avoid the damage is to install explosion proof equipment in intake pipe besides decreasing valve overlap angle. This paper introduces two types of methods designing explosion proof   equipment servicing gas engine and application of the latter explosion proof equipment on T16V280 gas engine.
