Benefits of technology
The invention is about a new design for turbochargers used in vehicles. The design includes a free portion on the shaft connecting the compressor to the turbine, which reduces heat transfer between the two casings and improves performance. The design also includes bearing housings that support the shaft and air deflection means to cool the compressor casing and prevent hot air from heating it. The invention also includes a vehicle that uses the new turbocharger design and a plurality of turbochargers can be installed on a single vehicle for optimal performance. Additionally, the invention includes a catalytic converter in the exhaust line to reduce toxicity of exhaust gases. These technical effects improve the performance and efficiency of turbochargers in vehicles.
Problems solved by technology
Indeed, it has been observed that the presence of a bearing housing surrounding all of that portion of the shaft between the compressor casing and the turbine casing gave rise to a non-negligible flow of heat from the turbine casing, which is therefore heated by the exhaust gases, to the compressor casing, in which any increase in temperature is therefore disadvantageous owing to the resulting decrease in density of the compressed air.

Embodiment Construction
[0020]FIG. 1 shows an embodiment of the turbocharger according to the invention. Thus, the turbocharger consists of a compressor casing 1 that houses a radial compressor, and of a turbine casing 2 that houses a radial turbine. The turbine is connected to the compressor by a shaft 3. Thus, the compressor draws in the air 4 that is intended to be admitted to the engine and, once it has compressed this air, thus sends it to the intake duct of the engine. The turbine, for its part, is driven by the exhaust gases 5 from the engine. The compressor casing 1 is secured to the turbine casing 2 via the intermediary of a plurality of bars 6 and attachment plates 7a and 7b secured to said casings 1 and 2. The shaft 3 comprises a free portion 8 between the two casings 1 and 2.
[0021]Thus, the free portion 8 communicates with the exterior of the turbocharger. In particular, the bars 6 allow the passage of a flow of air coming from the exterior of the turbocharger and flowing around the two casings...

A turbocharger includes a compressor and a compressor housing (1) surrounding the compressor, a turbine and a turbine housing (2) surrounding the turbine. The compressor housing (1) includes an inlet and an outlet for the air (4) entering a combustion chamber of an engine. The turbine housing (2) includes an inlet and an outlet for the exhaust gases (5), a shaft (3) linking the turbine and the compressor, at least one bearing for supporting and guiding the rotation of the shaft (3). The turbocharger includes attachment means (6, 7a, 7b) for attaching the turbine housing (2) to the compressor housing (1). The shaft (3) includes a free portion (8) between the two housings (1, 2), the attachment means (6, 7a, 7b) being suitable for allowing the passage of a flow of air circulating along the free portion (8) and around the turbine housing (2) and compressor housing (1).
Description
FIELD OF THE INVENTION[0001]The invention relates to a turbocharger, in particular a turbocharger for an internal combustion engine.DESCRIPTION OF THE PRIOR ART[0002]The turbocharger is a forced induction system very widely used in internal combustion engines for the purpose of increasing the power of these engines. The principle is to increase the density of the air supplied to the combustion chamber of the engine by compressing it using a compressor that is connected by a shaft to a turbine which is in turn set in rotation by the exhaust gases. For optimal operation, a turbocharger generally requires the use, downstream of the turbocharger, of a heat exchanger in order to cool the air and thus further increase its density, since compressed air generally has an elevated temperature at the outlet of the turbocharger. Owing to their high temperature, the exhaust gases constitute the main source of heat within the turbocharger. Thus, these exhaust gases drive an increase in temperatur...
