摘要： In an apparatus for controlling the EGR in a diesel engine, a single pressure control valve adjusts the control pressure from a pump automatically when the pressure changes, and supplies the control pressure in response to the command signal of a control circuit to an EGR valve and a waste-gate valve of a turbocharger. The pressure control valve includes an electric actuator, a spool valve, a sleeve, a diaphragm, and a spring. By using this apparatus, a diesel engine which has a high response speed, high control precision, simple constitution, less nitrogen oxides in the exhaust gas, and low manufacturing cost is obtained.

摘要： In an EGR control system for a diesel engine, the EGR amount is controlled by controlling the pressure in a diaphragm chamber of an EGR valve using the output signal of a computer, responsive to signals from a plurality of engine running condition sensors, for calculating the EGR amount with corrections according to the engine running conditions and the excess air rate. In some cases, the EGR is carried out only when the rotational speed of the engine is higher than a predetermined rotational speed. Also, in some cases, the EGR is carried out when an occurrence of idling is detected, even if the rotational speed of the engine is lower than the predetermined rotational speed.

摘要： An atmospheric pressure compensation system for an exhaust gas recirculation (EGR) of an internal combustion engine comprises a vacuum source for generating vacuum of a substantially constant absolute value, an EGR valve for regulating the gas flow passing through an EGR passage by means of the vacuum, an atmospheric pressure compensation valve for opening and closing a passage for transmitting the vacuum from the vacuum source to the EGR valve, a control circuit for detecting the engine running conditions and generating a control signal, and an actuator for contributing to actuate the compensation valve in response to the control signal. The atmospheric pressure compensation valve comprises a valve body defining at least two chambers partitioned by a diaphragm. The atmospheric pressure is introduced into one of the chambers, while the substantially constant vacuum from the vacuum source is introduced into the other chamber. A servo valve is operatively connected to the diaphragm and to the actuator. The servo valve is subjected to a force of the actuator and the pressure difference between the atmospheric pressure and the substantially constant vacuum.
