摘要： An exhaust gas recirculation device of an internal combustion engine includes a turbocharger (5), a low-pressure EGR passage (31), a high-pressure EGR passage (41) and an air flow meter (7). The device feedback-controls the high-pressure EGR gas amount in accordance with the fresh air amount, and open-loop controls the low-pressure EGR gas amount on the basis of the state of operation of the internal combustion engine. The device sets the degrees of opening of appliances and the fresh air amount at reference values. On the basis of the fresh air amount measured when the setting is done, the device learns and corrects a relationship between the low-pressure EGR gas amount and the degrees of opening of the appliances capable of adjusting the low-pressure EGR gas amount.

摘要： PROBLEM TO BE SOLVED: To provide a controller suppressing degradation in exhaust gas in a running gear for a vehicle equipped with an engine and an auxiliary machine driven by the engine. SOLUTION: The load of the auxiliary machine is reduced by an auxiliary machine control means 114 so that an EGR rate by an EGR device 64 is set to an EGR rate threshold (an EGR rate determination value) or more set based on the operating condition of the engine 8. Thereby, the EGR rate reduced according as the operation condition of the engine 8 becomes in a high load operating condition is made in the low load operating condition of the engine 8 which is set to the EGR rate threshold or more. In other words, an area where the engine 8 is made in the low load operating condition so as to secure the EGR rate threshold or more is widened, and degradation in exhaust gas is suppressed. The load of the auxiliary machine is reduced by the auxiliary machine control means 114, thereby output required for traveling a vehicle is secured. COPYRIGHT: (C)2007,JPO&INPIT

摘要： An IC engine has a single exhaust gas regulation (EGR) control valve (12,13) to feed back a variable proportion of the exhaust gases into the inlet manifold. The total gas flow in the engine is measured, as is the amount of fresh air intake. A processor calculates the difference between the two gas values to determine the amount of EGR.

摘要： PROBLEM TO BE SOLVED: To provide an engine control system to enable the prevention of hunting in a target VNT opening (a first control command value) of a variable nozzle in a variable nozzle turbo charger or a target EGR opening (a second control command value) of a flow control valve in an exhaust gas recirculation system.

Thus, when the hunting of the target VNT opening or the target EGR openig is detected, a first or a second gain correction coefficient multiplied by first or second feed back amount respectively is changed over to the value to lessen the absolute value of the first and the second feed back amount.
