摘要： The present invention relates to an arrangement for recirculation of exhaust gases of a supercharged combustion engine. The arrangement comprises an exhaust line intended to lead exhaust gases out from the combustion engine, an inlet line intended to lead air which is at above atmospheric pressure to the combustion engine, a compressor adapted to the inlet line so that it is possible, via the return line, to recirculate exhaust gases from the exhaust line to the inlet line. The arrangement comprises a first EGR cooler in which the recirculating exhaust gases in the return line are cooled by the air in a portion of the inlet line which is situated downstream of the compressor in the inlet line with respect to the direction of flow of the air in the inlet line.

摘要： A compression ignition engine (10) has a control system (40), one or more combustion chambers (12), and fuel injectors (42, 44) for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of engine speed and engine load to select a particular domain for engine operation (HCCI, HCCI+CD, or CD,—FIG. 1). When the processing selects HCCI, the engine is fueled to cause alternative diesel combustion (such as HCCI) in all combustion chambers. When the processing selects CD, all combustion chambers are fueled for conventional diesel combustion. When the processing selects HCCI+CD, a first group of combustion chambers are fueled for HCCI combustion and a second group for CD combustion. Each group (G1, G2) has its own EGR valve (34, 38) and turbocharger (22, 24).

摘要： A method for an internal combustion engine includes the steps of collecting exhaust gas in a volume (902) and flowing exhaust gas out of the volume in a first and a second portions (904). The first portion forms a tailpipe gas stream (906), and the second portion forms an EGR gas stream (908). The tailpipe gas stream goes through a turbine (910). The EGR gas stream is catalyzed by an oxidizer coating in a heat exchanger, and thermal energy is transferred from the EGR gas stream to the tailpipe stream in the heat exchanger (916).

摘要： A method and system for controlling the temperature of recirculated exhaust gas in an exhaust gas recirculation (EGR) system, such as those used in connection with diesel engines. An EGR loop (which may be either a high pressure loop or a low pressure loop) has a dual-leg segment with an EGR cooler on one leg and an EGR heater on the other leg. By means of a valve, the EGR gas may be diverted to either one leg or the other, thereby providing either cooled or heated EGR gas to the engine.

摘要： The invention relates to a direct-injection internal combustion engine that is operated in a first operating range associated with the low part load, with largely homogeneous combustion of the mixture and subsequent injection. Said internal combustion engine is operated in a second operating range associated with the middle part load, with low-temperature combustion of the mixture. In this way, minimum nitrogen oxide and soot emissions and a high degree of efficiency can be achieved both in the lower part load region and up to the full load region.

摘要： EGR systems for an internal combustion engine configured to operate using multiple-staged turbochargers, or a pair of single stage turbochargers, to provide exhaust gas recirculation to meet emissions requirements while not affecting engine performance. One or two EGR loops operating at low, intermediate, or high pressures may be employed. EGR exhaust gases may be taken directly from the exhaust manifold, or after the exhaust stream has passed through a turbocharger turbine. EGR exhaust gases may be injected at an intermediate pressure between stages of a multiple stage turbocharger, or alternatively between a low pressure turbocharger compressor and high pressure turbocharger compressor, before being boosted to a pressure high enough to ensure the desired mass flow to the engine and delivered to the intake manifold. Intake air may be pressurized prior to mixing with the EGR exhaust gases.
