Description

  The present invention relates to an eddy current turbocharger power system related to the structure of a vehicle power unit.

A typical vehicle has a constant power output energy at the time of shipment, and the power source of the vehicle is obtained from the engine. Engine power is generated mainly by gas introduced from the intake end entering the combustion chamber of the engine. It is mixed with oil gas and combusted, and the piston is pushed by the explosive force of the explosion caused by the combustion to generate drive power. For this reason, the combustion efficiency directly affects the output at the rear end, and in order to achieve a preferable output as it approaches the complete combustion, the completely burned air is often input to the combustion chamber of a general vehicle engine. Larger than the amount of gas produced.
Further, a turbine turbocharger system 10 (see FIG. 1) exists in the market, and mainly includes a cylinder 11, an exhaust gas turbine 12, and a drive compression turbine 13. The exhaust gas combusted by the cylinder 11 is input to the exhaust gas turbine 12 communicated from the exhaust end 111 to drive and rotate the exhaust gas turbine 12, and the exhaust gas turbine 12 rotates the drive compression turbine 13 in conjunction with the drive shaft 121. The drive compression turbine 13 simultaneously sucks fresh air, and the fresh air sucked by the drive compression turbine 13 is compressed, and then gas is fed into the intake end 112 of the cylinder 11. Thereby, the cylinder 11 receives the compressed air and combustion efficiency increases.

However, the above-described turbine turbocharger system 10 needs to generate power by receiving exhaust gas, and needs to absorb and compress fresh air. For this reason, it cannot be realized by a single turbine, and it is necessary to arrange one exhaust gas turbine 12 and one drive compression turbine 13. Therefore, the entire turbine turbocharger system 10 has a constant weight and volume, and the load on the vehicle also increases. In other words, in terms of construction, the turbine turbocharger system 10 must be joined between the exhaust end 111 and the intake end 112 of the engine, and the arrangement of the pipelines and the arrangement of the members has expertise. If it is not an expert, it cannot be smoothly installed in the vehicle.
It is difficult for a general user to install by himself, so when a general user installs the turbine turbocharger system 10, he / she bears the cost of the overall structure and the installation service cost of an expert. Because it has to be done, users tend to hesitate to use it, affecting the economic effect.
