Effect of Injection Timing on Backfire of Port Injection Hydrogen Engine 2008-01-1788

A four-cylinder four-stroke gasoline engine is modified to a hydrogen engine, with the rebuilding of fuel supply and control system. The phenomenon of backfire is described and the effect of injection timing on backfire of port injection hydrogen engine is analyzed. The minimum start of injection (SOI) is derived considering the response time of the electromagnetic solenoid valve. It is finally found that the minimum SOI is approximately linear with the engine speed at a fixed engine load.
