What is the reason why cars can't afford gasoline?

There is something wrong with the gasoline pump, the oil pump is damaged or the oil pressure is too low to pump gasoline from the oil tank;

Impurities in the oil tank block the oil pump or oil inlet;

Blockage of fuel system, such as nozzle, gasoline filter or fuel quality;

Air intake system is blocked, such as air filter and air flowmeter;

The ignition system is not easy to use, such as spark plugs and high-voltage lines.

Incorrect valve timing, such as lax sealing of intake valve and exhaust valve.

When the car is cold, the gasoline is not completely atomized, which causes the mixture to be diluted, and it feels that no oil can be added. In fact, the power can't be reached, and the engine runs unevenly. Now cars are all EFI. In the past, it was a vaporizer with a valve to thicken the mixture. It is suggested to let the car idle for five minutes to warm up before going out, which can prolong the service life of the car.

Gasoline is a blend of straight-run gasoline, catalytic cracking gasoline and catalytic reforming gasoline obtained from petroleum refining with high octane number components, which is mainly used as fuel for automobile ignition internal combustion engines.
