Document Type and Number:
Japanese Patent JP2590170
Kind Code:
B2
Abstract:
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 (10) includes a multiple-orifice fuel injector (22), a baffle (138) having a concave surface (146), and a fuel ignition-initiating device (22) such as glow plug positioned generally in spaced relation between the fuel injector (22) and the concave surface (146). The baffle (138) intercepts and temporarily maintains a stoichiometric preselected portion (34,38) of at least one, and preferably two, fuel streams (102,106) in ignitable proximity to the fuel ignition-initiating device (26) to positively start a localized flame (42) of burning fuel. The baffle (138) controlledly reflects and rapidly directs the resultant expanding flame (42) of burning fuel to all of the remaining fuel streams (110) so that they are interconnectedly bridged with the flame (42) and thereby positively ignited.
