摘要： A method and a device for exhaust gas recycling (EGR) in a combustion engine having two exhaust collectors. EGR gasses from the two exhausts collectors are combined in a mixing section of the EGR channel where they are accelerated, in a contraction portion, mixed and expanded. EGR gasses from a first exhaust collector are led into a first and EGR gasses from a second exhaust collector are led into a second portion of the contraction portion, which is arranged sideways with respect to the first portion of the contraction portion and separated therefrom up to the upstream area of the transition portion.

摘要： An airflow system for an engine includes first and second turbines coupled with first and second compressors, respectively. The first turbine receives exhaust from an exhaust manifold, and the first compressor supplies compressed air to an intake manifold. A wastegate valve, fluidly coupled with the exhaust manifold, is movable between a first position allowing exhaust to bypass at least one of the turbines and a second position restricting exhaust from bypassing. A controller restricts the supply of pressurized air to the wastegate valve such that the wastegate is in the second position when at least one of (i) a load of the engine is less than or equal to a predetermined load, (ii) a speed of the engine is less than or equal to a predetermined speed, and (iii) a temperature of air leaving the first compressor is less than or equal to a predetermined temperature.

摘要： In a two-stage concept for supercharging of internal combustion engines, in which the first stage is performed by an exhaust-gas turbocharger and the second stage by an electrically driven compressor, the compressor is also used to provide the secondary air used for the heating of a catalytic converter. In this manner, the catalytic converter quickly reaches an efficient operating temperature.

摘要： An arrangement for feeding air in a supercharged piston engine includes at least a supercharging device arranged for feeding air to more than one cylinder, an air chamber in connection with the supercharging device, and a channel arrangement leading from the air chamber to each cylinder of the piston engine. A resonator system is in connection with the air chamber for attenuating the pressure pulsation in the air chamber. In a method of operating the supercharged piston engine, combustion air is fed by means of the supercharging device at a pressure higher than ambient pressure into the air chamber, air is led from the air chamber to the cylinders through the channel arrangements, and a pressure pulsation is formed in the air chamber, which pulsation is half-wavelength shifted from the pulsation in the air chamber, appearing at frequencies at or below the third harmonic of the rotational speed of the engine.
