Methods to identify the quality of gasoline are as follows: 1. Gasoline color: When refueling your car, pay attention to the color of the gasoline. Under normal circumstances, gasoline should be water-white in color. If the color darkens, it may indicate that the gasoline has been stored for too long and has undergone chemical reactions. 2. Usage observation: Check if fuel consumption has increased and inspect the exhaust pipe for any sticky substances. If present, it suggests the gasoline is of poor quality. Also, observe whether knocking occurs during use or if there are difficulties in ignition. 3. Smell test: Gently waft the gasoline's odor. If there is a pungent smell, such as a spicy or eye-irritating smoke-like odor, it means the gasoline contains excessive sulfur and usually other impurities. 4. Touch test: Rub a small amount of gasoline between your fingers several times. If the greasy sensation is strong, similar to engine oil, it indicates poor quality. Alternatively, pour a little gasoline on your hand—if it evaporates quickly, the gasoline is of good quality.

What is the reason for fault code 00546?

Cars are equipped with numerous sensors, which display different fault codes when they detect issues. When fault code 00546 appears, the corresponding measures are: clean the throttle valve, check whether G188 is functioning reliably, and if it is working normally, replace the engine wiring harness. More information about automotive fault self-inspection is as follows: 1. The angle sensor 1-G187 and angle sensor 2-G188 in the throttle unit are used to determine the current position of the throttle valve and transmit this information to the engine control unit. 2. The vehicle fault self-inspection terminal and automotive fault diagnostic tool (also known as a car decoder) are portable intelligent automotive fault self-inspection devices used to detect car faults. Users can quickly read faults in the car's electronic control system and, through the LCD screen, display fault information to promptly identify the location and cause of the fault.

What does engine backfire mean?

Backfire refers to the phenomenon of backfiring in the intake manifold. Below is a relevant introduction to engine backfiring: Causes of backfiring: Backfiring in the intake manifold is caused by insufficient fuel supply and an overly lean air-fuel mixture. An excessively lean mixture slows down the combustion speed, causing the combustion to continue until the end of the exhaust stroke when the intake valve opens. The fresh air-fuel mixture encounters unburned exhaust gases in the cylinder, ignites, and flows backward through the intake manifold, resulting in backfiring. Ignition misfiring: If backfiring in the intake manifold is accompanied by severe engine shaking, exhaust popping, and a significant drop in engine power, it is likely caused by ignition misfiring. Due to incorrect ignition timing, when a cylinder is in the intake stroke with the intake valve open and the spark plug fires at that moment, it can lead to backfiring in the intake manifold.

What is the trick for a loose cigarette lighter socket?

Cigarette lighter socket becomes loose can be fixed by using a small screwdriver to slightly bend the metal contact inside the socket towards the center to tighten it. The reason for the loose cigarette lighter socket is due to the failure of the spring contacts inside. The specific steps are as follows: 1. Find a piece of steel wire about 2mm in diameter and make a small hook at the front end. 2. Then flatten the front end of the hook with a hammer. 3. Use a flashlight to illuminate the cigarette lighter socket, identify the spring contacts, and gently bend them inward with the hook (there are two symmetrical contacts). Many cigarette lighter sockets tend to become loose over time. When not in use, it's advisable to cover the cigarette lighter socket with its cap to prevent water from entering.
