Problems solved by technology

[0007] In general, a turbocharger driven by exhaust gas (hereinafter referred to as a "mechanical turbocharger") may have low responsiveness, and it is difficult to achieve an engine with a high compression ratio due to high back pressure
In addition, since the turbocharger is exposed to high-temperature exhaust gas (ie, 700 degrees Celsius), the design cost of the peripheral parts of the turbocharger increases
[0008] Further, since the output power of the electric motor is limited by the output of the battery installed in the vehicle, the use of the electric supercharger is limited to the low-middle speed range

Abstract

According to an embodiment of the present invention, an engine system comprises: an engine including a plurality of combustion chambers for generating a driving force by combustion of fuel; a plurality of intake lines in which external air supplied to the combustion chambers flows; and electric superchargers individually installed in the intake lines.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Korean Patent Application No. 10-2016-0169527 filed in the Korean Intellectual Property Office on December 13, 2016, which is hereby incorporated by reference in its entirety. technical field [0003] The present application relates to an engine system. More particularly, the present application relates to an engine system capable of high compression ratios. Background technique [0004] The engine properly mixes air and fuel, and generates driving power by burning the mixed gas. In order to obtain the required or desired power output and combustion efficiency, sufficient air should be supplied to the engine. To this end, a turbocharger is used to improve combustion efficiency and supply sufficient air to the engine. [0005] Generally, a turbine of the turbocharger is rotated by the pressure of exhaust gas discharged from the engine, a compressor of the turbocharge...
