Gas engine and vehicle

The invention relates to the technical field of vehicles, and discloses a gas engine and a vehicle, according to the gas engine, two air inlet channels of each air cylinder are arranged to be parallel air channels and are symmetrically arranged tumble air channels, and tumble can be generated easily. According to the size of the crank angle, the air inlet valve divides the opening air inlet interval of the air inlet into two low-lift intervals and a high-lift interval located between the two low-lift intervals, and when the two crank angles are limited to be located in the low-lift intervals, the lifts of the two air inlet valves are the same, so that the requirement of the small lift for the air inlet amount in the air inlet process can be met; when the crank angle is located in the high lift interval, the lifts of the two air inlet valves are different, and effective vortexes can be generated, so that inclined shaft tumble flow is formed, the two air inlet channels arranged in parallel of each air cylinder
