Modified natural gas vehicle
To free up more space for fuel storage tanks, the modification of natural gas vehicles requires some improvements to the vehicle's suspension system. Sometimes, at the rear of the car, a semi-trailer suspension system is used to replace the stabilizer bar suspension system, which provides more space for the rear bracket, while also providing a smooth and comfortable ride. Natural gas vehicles also remove spare tires and jacks, thereby achieving a flat floor design. In order to make up for the lack of spare tires and jacks, "low pressure safety tires" are installed on the car to provide basic guarantee for tire replacement.
