摘要： A device for purifying exhaust gas of an internal combustion engine, to reduce the nitrogen oxide content, which has an exhaust conduit for introducing part of the exhaust gas into an intake passage of the engine, a valve provided in the exhaust conduit opened by a diaphragm device to allow passage of the exhaust gas when the vacuum acting on the diaphragm device becomes over a predetermined value, a vacuum conduit for introducing the vacuum of the intake passage of a carburetor into the diaphragm device, said vacuum conduit being connected to the intake passage at a position adapted to open upstream of the throttle valve when the throttle valve is closed and to open downstream of the throttle valve when the throttle valve is slightly opened, control means operating to sense the engine temperature and provided in the vacuum conduit, said control means introducing the intake vacuum into the diaphragm device when the sensed temperature is over a predetermined value and for shutting off the introduction of the intake vacuum into the diaphragm device when the sensed temperature is below a predetermined value whereby the part of the exhaust gas is introduced into the intake passage only when the engine temperature becomes over a predetermined value and the intake vacuum becomes over a predetermined value.

摘要： Internal combustion engine exhaust gases, passing unreacted through an exhaust gas catalytic or thermal reaction device during the warmup period of the device, are directed to an expansible container which retains the entire flow of exhaust gases or to a container of filter, adsorptive and absorptive material which retains undesirable constituents of the exhaust gases. After warmup of the reaction device, the retained gases or constituents are recirculated to the engine induction system or the reaction device. This approach supplements the emission control of the reaction device by preventing emission of undesirable exhaust gas constituents during starting of the engine and warmup of the reaction device.

摘要： An engine controller controls a direct fuel-injection engine including a fuel injection valve for directly injecting a fuel into a cylinder and a valve overlap period adjusting mechanism for adjusting a valve overlap period between an open period of an intake valve and an open period of an exhaust valve. The engine controller is provided with an acceleration request sensor for detecting an acceleration request of a driver, and when the acceleration request occurs and a top surface temperature of a piston in the cylinder is lower than a predetermined temperature, the engine controller extends the valve overlap period between the open period of the intake valve and the open period of the exhaust valve, ranging before and after an exhaust top dead center.

摘要： Methods and systems are provided for flowing exhaust through a second cooler, arranged downstream of a first cooler and upstream of an intake in an exhaust gas recirculation passage, and extracting condensate for water injection from condensate in cooled exhaust gas exiting the second cooler. In one example, a method may include adjusting the amount of exhaust gas flowing through the second cooler based on an amount of water stored at a water storage tank of a water injection system and engine operating conditions. Further, the method may include selectively flowing exhaust gas from the second cooler to a location upstream or downstream of a compressor in response to engine operating conditions.

摘要： A flow rate controller of an internal combustion engine includes a flow rate change section configured by including an EGR valve, a bypass valve, and a diesel throttle, as the flow rate change section capable of changing at least one of a flow rate of exhaust gas that is recirculated to an intake system from an exhaust system of an internal combustion engine via an EGR passage and a flow rate of fresh air that flows into the internal combustion engine. In addition, an ECU is included to realize: an arrival position determining section for determining an arrival position of condensed water in the EGR passage that is moved by the EGR at least either at the time of acceleration or at the time of deceleration of the internal combustion engine; and a control section for controlling the flow rate change section on the basis of the arrival position determined by the arrival position determining section.

摘要： A six-stroke engine system including an engine with a combustion chamber including an exhaust valve that expels exhaust gasses during an exhaust stroke, and a blowdown exhaust valve that expels blowdown exhaust gasses during recompression. An intake line directs air into the combustion chamber, and an exhaust line directs exhaust gasses from combustion chamber. A blowdown exhaust line directs blowdown exhaust gasses out of the combustion chamber and into the intake line. The blowdown exhaust gasses are expelled through the blowdown exhaust valve during recompression, and exhaust gasses are expelled through the exhaust valve during the exhaust stroke.

摘要： A diesel engine system includes a diesel engine, a throttle valve, an EGR (Exhaust Gas Recirculation) path, an EGR valve and a controller. The throttle valve controls a flow rate of intake air to the diesel engine. Exhaust gas is recirculated along the EGR path from an exhaust port to an intake port of the diesel engine. The EGR valve controls a flow rate of the exhaust gas. The controller controls the throttle valve and the EGR valve such that an opening of the throttle valve decreases and an opening of the EGR valve increases when a load of the diesel engine increases. The controller controls the EGR valve such that the opening of the EGR valve increases after the opening of the EGR valve is held constant for a first predetermined holding time.
