Patent ID: 8793043

Claim:
A hybrid vehicle comprising: a linear engine controlled by HCCI (Homogeneous Charge Compression Ignition) combustion in an operation section where an engine power is used for generating electricity after being started and reaching up to a predetermined RPM; and a motor-combined generator engaged to the liner engine and starting the linear engine and charging a battery by converting an entire engine power of the linear engine generated by the HCCI combustion into electricity generation power; wherein the linear engine performs a four-stroke cycle by putting two two-stroke cycle linear engines in parallel; and wherein the linear engine includes: a first linear engine where an expansion stroke due to explosion is generated at 45 degrees and 90 degrees in an entire stroke cycle; and a second linear engine that is arranged in parallel with the first linear engine and where an expansion stroke due to explosion is generated at 135 degrees and 180 degrees in the entire stroke cycle, wherein the engine power of the first linear engine and the second linear engine is transmitted to a crank connected to the motor-combined generator.
