Abstract of the Disclosure Flame Incubating and Propagating Apparatus For A Fuel Combustion System Conventional direct-injection internal combustion engines having a fuel injector with multiple fuel spray orifices will not completely ignite and burn relatively lower-cetane-number alternative fuels such as 100 percent methanol or ethanol. That is because the fuel spray injection pattern, per se, usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by sectors of fuel-deficient intake air. The present fuel combustion system includes a multiple-orifice fuel injector, a baffle having a concave surface, and a fuel ignition-initiating device such as glow plug positioned generally in spaced relation between the fuel injector and the concave surface. The baffle intercepts and temporarily maintains a stoichiometric preselected portion of at least one, and preferably two, fuel streams in ignitable proximity to the fuel ignition-initiating device to positively start a localized flame of burning fuel. The baffle controlledly reflects and rapidly directs the resultant expanding flame of burning fuel to all of the remaining fuel streams so that they are interconnectedly bridged with the flame and thereby positively ignited.
