Definitions

  • the present invention relates to a method for Regulation of an internal combustion engine with a gas dynamic Pressure wave machine according to the preamble of claim 1.
  • a gas dynamic pressure wave machine that is designed to supply charge air to an internal combustion engine is from the WO 99/11913 by the same applicant is known.
  • a rotatable air housing to the Openings of one of the two high pressure channels with respect to the align other openings of the other high pressure duct, for process coordination across the entire map area to achieve the internal combustion engine as well as a variable Width adjustment of the high pressure exhaust duct and others Characteristics.
  • the driving behavior can initially be roughly divided into two stages divide, i.e. the acceleration and braking level as well the constant level. A distinction is made in the first stage between two phases, a positive load jump at Accelerating and a negative load jump when braking, or accelerate away.
  • the second stage can be divided into three phases subdivide, part load phase, idle phase and constant Vollastphase.
  • the present invention relates in particular to the positive load jump when accelerating as well as the negative Load jump when accelerating or braking with subsequent part-load behavior.
  • the Pressure wave charger can be damaged, for example
  • the rotor is supported by strips on the housings or due to high exhaust gas recirculation and / or too low Boost pressure and / or too high charge air temperature Engine operation is disrupted.
  • FIGs 1 and 2 is a gas dynamic Pressure wave machine shown on a variety of Improvements have been made to the total To increase efficiency significantly.
  • the pressure wave machine 30 is via the high-pressure exhaust duct 31 and the high-pressure charge air duct 32 with the schematically shown Internal combustion engine 33 connected.
  • the low-pressure exhaust duct 35 Located in the gas housing 34 the low-pressure exhaust duct 35, and it is off.
  • the rotor 40 can also be seen with its cells 41, the rotor in a jacket 42 is arranged and for example by a belt drive 43 is driven.
  • the first aim is to align the Opening edges of the high pressure exhaust duct with respect to Opening edges of the high pressure charge air duct in such a way vote that the so-called primary wave, which at Opening the high-pressure exhaust duct to the lower pressure standing rotor cell, is precisely coordinated, such that when opening the high pressure charge air duct Rotor cell arrives on the air side. It was earlier tries to achieve this optimization by Housings rotatable discs with openings attached to influence the two high pressure flows.
  • the twist of the housing can, for example 0 - 25 °.
  • the connecting line 46 in FIGS. 1 and 2 From the high pressure charge air duct into the high pressure exhaust duct leads. As a result, the positive pressure surges in the High-pressure charge air duct on the high-pressure exhaust gas duct transfer.
  • the connecting line contains a Check valve 47, optionally with a electronic control is provided. It works Check valve as a regulation in the sense that only Pressure surges are transmitted, their energetic level is higher than the current pressure in the high-pressure exhaust duct. In particular, the negative pressure pulses, i. H.
  • the pressure wave machine is after State of the art heavily dependent on filling.
  • Reduction of pressure pulsations as described above allows the provision of a connecting line Return of charge air to the high pressure exhaust side of the Pressure wave machine, thereby increasing the Mass throughput of the machine and thus an increase in Fill levels, which results in a significant increase in pressure noticeable.
  • An additional regulation of the returned Fresh air high pressure volume by means of a regulated Check valve can therefore be used to control the charge pressure in the general and in addition to the Otto engine Power control can be used. That means with others Words that the pressure wave machine to improve the Compression efficiency at higher engine throughputs can be dimensioned somewhat larger without lower ones Losing engine throughput to boost pressure.
  • Cross section of the connecting channel by means of a suitable, known device is regulated, either regulated check valve or an additional one Cross-sectional control can be used.
  • This is particularly effective in lower to medium speed, Temperature and load range of the internal combustion engine.
  • the means the system to increase performance by means of Connection line is a tool to help with possibly low achievable boost pressure at low engine speeds, from 1,000 to 3,000 RPM, a sharp increase in boost pressure by utilizing the exhaust gas pulsations and the positive ones To achieve pressure difference over the pressure wave machine.
  • Figures 3 and 3A relate to another aspect the pressure wave machine, on influencing the High pressure exhaust flow.
  • 3A is one Influencing the high pressure exhaust duct, or its Broadening, shown schematically.
  • the developed rotor 40 shown with the cells 41 and a Recess 48 provided in the gas housing 34, through a Slider 49 can be changed as indicated by the arrow 50 is indicated.
  • the slide 49 is completely in Arrow direction indented so that the high pressure exhaust duct is widened without creating a web.
  • the slider can be moved so that the High pressure channel is widened until the pressure inside it is that the pressure wave process generated boost pressure drops to the desired level.
  • check valve is the Connection line may only be opened when all other parameters and actuators after the positive Load jump, because of the requirement of the highest possible Boost pressure, are already in the optimal position. This is required because with the performance enhancement system High pressure process intensified at the expense of the flushing process becomes.
  • the method according to the invention is not based on that described system internal combustion engine-pressure wave machine limited.
  • the procedure is for everyone Systems internal combustion engine-pressure wave machine validity. It unfolds its full effectiveness with all options. This procedure also applies to both Otto and Diesel engines, with and without catalytic converters and with or without Additional heaters.
