A rectifier is a device that converts alternating current (AC) to direct current (DC). The function is to help the car to eliminate clutter interference, stabilize the output voltage, improve the instantaneous discharge capacity of the power system, increase the torque output, speed up the throttle response, prolong the battery life, shorten the starting time of the car engine, and improve the ignition efficiency.
Chrome alloy material, surface anti-oxidation treatment, ceramic hybrid structure, strong and durable.
Replacing 4012748, converting high-voltage unstable alternating current into voltage-stable 12v direct current, protecting battery and vehicle circuit system, reducing load and prolonging vehicle life.
The performance of onboard electrical equipment and other related components will gradually degrade as the rectifier fails, rendering the vehicle inoperable in some cases.

A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the action of the vacuum generated by the engine. The carburetor is a precision mechanical device that uses the kinetic energy of the inhaled air stream to achieve gasoline atomization. Its important effect on the engine can be called the "heart" of the engine. The complete device should include starting device, idle speed device, medium load device, full load device, and acceleration device. The carburetor will automatically proportion the corresponding concentration according to the requirements of the different working conditions of the engine, and output the corresponding amount of mixed gas. In order to make the mixed gas mixed evenly, the carburetor also has a fuel atomization device. Effect for normal operation of the machine.
