What is the reason why the tricycle cold car caught fire and smoked?

The reasons for the fire and smoke of the tricycle cold car are as follows:

When the cold car starts, it emits black smoke, which is mainly caused by insufficient combustion and excessive mixture. For this problem, I suggest you check the throttle carbon deposit, oxygen sensor, air flow meter, nozzle atomization and other related components. The sound emitted from the exhaust pipe may also be related to the excessive mixture.

It is the phenomenon that the intake pressure sensor exceeds the standard use range value and the signal is inaccurate.

If the fuel pressure is too high, the fuel injector will leak oil, which will also bring the above phenomenon;

The ignition time is too late, which will lead to the decline of power performance and poor fuel economy, and also lead to poor combustion of vehicles and black smoke.
