Streszczenie:

In order to efficiently supercharge Diesel engines with pressure wave superchargers it is necessary to correlate the superchargers rotation speed with certain parameters of the supercharged engine. For this purpose, to reduce the research costs and duration, simulation models can be used which help to determine the parameters which have a major impact on the supercharger's rotational speed and efficiency. In this paper there are presented two simulation models: a one-dimensional (made in AMESim software) and a three dimensional (made in Fluent Software). This simulation models offer the possib

The functional constructive variants of the Hyprex and Comprex compressors with pressure wave built until the present are reduced in number. Starting from this ascertainment, the paper proposes to highlight the optimization on joint functioning of existing pressure wave supercharger models with internal combustion engines. This is possible due to the efficiency of the supercharging process, realized with such superchargers, which depends on the correlation grade between the rotational speed of the supercharger and the pressure of the exhaust gasses that enter in the compressor's channels, reas

TThe efficiency of the turbochargers is not satisfactory while the supercharged engine is working at low speeds. The dual supercharging can represent a solution to improve the supercharging process efficiency of the turbochargers. Due to the different functioning principles of the turbochargers and the pressure wave superchargers, this compressors are not having the same efficiency when the engines is running at a certain speed. The pressure wave superchargers can operate with a satisfactory efficiency at low-medium engine speeds. For this reason the dual supercharging with turbocharger-pressu

With the advantages of good low-speed torque capability and excellent instant response performance, twin-screw superchargers have great potential in the automobile market, but the noise of these superchargers is the main factor that discourages their use. Therefore, it is important to study their noise mechanism and methods of reducing it.

Engine downsizing is a proven approach for achieving a superior fuel efficiency. It is conventionally achieved by reducing the swept volume of the engine and by employing some means of increasing the specific output to achieve the desired installed engine power, usually in the form of an exhaust-driven turbocharger. However, because of the perceptible time needed for the turbocharger system to generate the required boost pressure, a characteristic of turbocharged engines is their degraded driveability in comparison with those of their naturally aspirated counterparts.

Through the analysis of the sealing mechanism of the oil seals in exhaust gas turbo supercharger and the comparative test of different oil seals with the pressure change in the oil-return chamber, a seal that uses a caulking ring with reverse threads is designed, and an optimum combination of oil seal is selected. The combination of caulking ring and the oil-return thread structure has better complementary action on oil sealing, because for the seal with oil-return reverse thread there is better dynamic and static seal effect on ring seal and has good sealing performance and high reliability a

Abstract This paper is based on the simulation analysis of the supercharger front intake pipeline of the FSAE racing car engine. To limit engine power, the equation race requires an annular restrictor valve to be installed in the intake system with an inner diameter less than 20mm. Limiting valves have a great impact on the intake flow and engine performance. In this paper, the intake front segment is modeled, the simulation analysis is done by Fluent, and the GT-power engine simulation software is used to assist the simulation. A good intake front segment is obtained, which provides an effect

Simulation of the supercharged internal combustion engines operation cycle is impossible without correct estimation of the supercharger operating parameters. Standard approach is to use specially prepared performance maps of compressor and turbine of the turbocharger, which are based on the experimental (or manufacturer’s) raw data. Centrifugal compressor performance maps interpolation, extrapolation and treatment provides challenging requirements as it is important to get correct simulation under such special conditions as compressor choke, rotating stall and pumping surge.

Pressure-wave supercharger (PWS) is one technical way to boost the engine intake air pressure. PWS has several advantages such as less emission (especially NOx emission), rapid response when load changes, higher torque even at low engine speed. In this research a 493 diesel engine is charged by a pressure-wave supercharger (PWS). The emission performance of the PWS diesel engine is mainly investigated. Together with experimental test, the CFD simulation is completed basing on a 3D model of the PWS rotor channel. The CFD simulation results show that the inner EGR phenomenon happens especially w

In previous papers the authors have analyzed the functioning of the three lobe supercharger. This analysis was made possible by a complete analytical model of the rotors. The dynamic transformation of the chambers occupied by the fluid allows us to point out specific problems regarding trapped volumes and to design special devices to avoid these problems. As a result it is possible to simulate the performance of the compressor and to propose an analytical model in order to determine the dynamic loads on the rotors. The topic of this paper is the comparison between the performances achieved by
