  "textContent": "This invention aims at providing a fuel admission control unit to control a diesel engine, with which ensuring compatibility between the exhaust gas performance and the engine speed response performance is achieved by a simple control with a consideration of the residual oxygen in the EGR gas. A control unit to control a diesel engine having an EGR system includes: an estimation excess air ratio » S computing means (47) that is an arithmetic section to compute an estimation excess air ratio » S , from the quantity of the fuel injected by the fuel injection valve (31) into the cylinder (3), the intake air flow rate measured by the air flow meter (35), and the flow rate of the residual oxygen in the EGR gas that returns back into the intake air system; and a fuel admission control means (33 or 51) that controls the fuel flow rate under hard acceleration, based on the estimation excess air ratio » S that is computed by the estimation excess air ratio » S computing means.",
