Fuel injection controlling apparatus for engine |
摘要 |
The invention provides a fuel injection controlling apparatus for an engine that reduces NOx amounts in an exhaust gas of a Diesel engine conducting lean combustion. An inter-cylinder injector (20a) is arranged in each cylinder of an engine (1). An intake port/manifold injector (21a) is arranged at an inlet of each cylinder of an intake manifold (5). A speed sensor (32) for detecting the engine speed is provided to the engine. A controller (31) is connected to the speed sensor (32), the inter-cylinder injector (20a) and the intake port/manifold injector (21a), and calculates an engine load. The intake port/manifold injector (21a) injects the fuel when the engine load is low, and the inter-cylinder injector (20a) injects the fuel when the engine load is high.
