PROBLEM TO BE SOLVED: To provide a fuel injection control device for an engine, reducing an amount of NOx in an exhaust gas from a lean-burn diesel engine. SOLUTION: An cylinder indicator 20a is provided in each cylinder of the engine 1, an intake manifold injector 21a is provided at an inlet of the intake manifold 5 to each cylinder and a speed sensor 32 is provided for detecting an engine speed. The control device 31, the speed sensor 32, the cylinder injector 20a and the intake manifold injector 21a are connected together to allow the control device 31 to calculate an engine load. A fuel is injected from the intake manifold injector 21a during a low engine load and injected from the cylinder injector 20a during a high load. |
