Title:
内燃機関における排気浄化用触媒装置の燃料供給装置
Document Type and Number:
Japanese Patent JP4471896
Kind Code:
B2
Abstract:
Cylinder heads (13L, 13R) are each provided with a fuel injection valve (14), and an addition nozzle (44) for adding fuel for activating an exhaust purifying catalyst (38) to an exhaust manifold (25L, 25R). There exists a non-exhaust period in which an exhaust gas does not flow out to exhaust passages (28L, 28R) from the exhaust manifolds (25L, 25R) during an operation of an engine (11). An ECU (46) controls the addition nozzles (44) in such a manner that the addition nozzles (44) execute a fuel addition during periods except the non-exhaust period. Accordingly, the fuel added to the exhaust manifolds for activating the catalysts (38) is avoided from collecting on a wall surface of an exhaust system without getting on an exhaust stream (Fig. 1).
