The diesel truck suddenly turned on the engine fault light. What happened to speeding? If the key is returned, please restart it.

There is something wrong with the throttle. Or carbon deposition will cause insufficient combustion of gasoline, leading to engine jitter. The influence of engine carbon deposition on automobiles is considerable. First, the engine power is reduced, that is, the uneven power output is gradually attenuated and the fuel consumption is increased.

The default maximum speed of cars is limited to 250km/h, but in China, because the maximum speed of most domestic cars is only a little more than 200km/h, many of them can't reach 200km, so there is no electronic speed limiter. Unless the driving computer is repainted and some minor adjustments are made, it is possible to really cancel the electronic speed limit, but this will cause hidden dangers and may cause certain damage to the car.

Extended data speed limit

The speed limit standard is not only based on the number of lanes, but also on the road grade, traffic flow, road width, isolation belt and other conditions. The speed limit of the first-class highway can be set to 60-100 according to the specific situation;

The secondary highway is 40-80, so there is a policy basis for setting the speed limit at 60.
