Is the car load value 70 normal?

Normal load ratio: 20-50.

Engine load refers to the load borne by the engine. When the engine bears a heavy load, the intake air volume and fuel injection volume will also increase accordingly. If the maximum load is exceeded, the service life of the engine will be shortened.

Load rate is a relative concept of torque percentage at a certain engine speed. Its strict definition refers to the ratio of the torque at part throttle to the maximum torque at full throttle at the same engine speed.
