Why does an automatic car still roll backward when in D gear?

Rolling backward when starting on a slope is unavoidable and a normal phenomenon. The procedure for starting an automatic car on a slope is to press the foot brake, shift into drive (D), release the handbrake, lift the right foot off the brake and press the accelerator. During the transition from lifting the brake to pressing the accelerator, there is a brief moment, and some drivers may be slower in their actions. Therefore, if the accelerator is pressed too slowly, the car will roll backward. Here is some related information about automatic transmissions: 1. Introduction: An automatic transmission, as the name suggests, does not require the driver to manually shift gears. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Generally, an automatic transmission car has six gear positions, from top to bottom: P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low). 2. Automatic Principle: The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, an automatic transmission consumes over 10% more fuel than a manual transmission. Whether manual or automatic, the more gears a transmission has, the more fuel-efficient it is.

How to Obtain the Inspection Flow Information of a Driver's License?

Querying the inspection records of a driver's license: Enter the driver's ID number to query, and the query results will display the annual inspection time of the driver or an abnormal status of the driver's license. The annual inspection time of the driver's license is based on the initial issuance date of the license as the cycle date. Every year, the driver must go to the vehicle management office on the annual inspection cycle date to process the annual inspection of the driver's license. Failure to do so within the specified time will result in the invalidation of the driver's license. Relevant information about vehicle annual inspection is as follows: 1. Introduction: Vehicle annual inspection (Vehicles-inspection), also known as motor vehicle inspection. Depending on the usage nature of the motor vehicle, the inspection items and scope may vary. 2. Inspection items: According to the definition in RB/T218-2017 "Requirements for Qualification and Capability Assessment of Inspection Bodies—Motor Vehicle Inspection Institutions," motor vehicle inspection includes three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive performance inspection of vehicles.

Is the brake on the left or the right?

In an automatic transmission vehicle, the brake is on the left and the accelerator is on the right. Whether it's a manual or automatic transmission, the only difference underfoot is the presence or absence of a clutch. In an automatic transmission, there is no clutch on the left side, so the left foot remains idle. Automatic transmission vehicles typically use a hydraulic transmission device to replace the mechanical clutch in manual transmission vehicles, hence there is no clutch pedal. When the engine speed is low, the torque transmitted by the fluid is limited and insufficient to propel the vehicle forward. The reasons for unusual noises when braking in an automatic transmission vehicle are as follows: 1. Normal ABS activation: The ABS operation process is actually a cycle of locking-releasing-locking-releasing, keeping the vehicle in a state of near-lock rolling. Therefore, when the ABS is triggered by hard braking, it produces a clicking sound, which is normal. In this case, simply press the brake pedal firmly to the floor. 2. Gear noise when braking in an automatic transmission vehicle: If you hear a clicking sound between the transmission and the gear lever when pressing the brake pedal, the main reason for this noise may be the electronic linkage between the brake system and the automatic transmission. Pressing the brake activates the transmission solenoid valve, producing the clicking sound. This serves as a safety reminder, requiring the gear lever lock button to be pressed before shifting gears.

What Precious Metals Can Be Extracted from a Car's Catalytic Converter?

The catalytic converter can extract platinum group metals. A car's catalytic converter contains many precious metals. The catalytic converter is used to purify exhaust gases, and this component is installed at the front section of the exhaust pipe. If a car has two front sections of the exhaust pipe, it may have two or even more catalytic converters. Without a catalytic converter, the toxic and harmful substances in the car's exhaust would exceed the standard, polluting the environment. The catalytic converter has an oxygen sensor at both the front and rear. The front oxygen sensor is called the upstream oxygen sensor, while the rear one is called the downstream oxygen sensor. The main function of the upstream oxygen sensor is to detect the oxygen content in the exhaust. The sensor can feed this data back to the ECU, which then adjusts the air-fuel ratio accordingly. The air-fuel ratio is a crucial parameter for the engine. The downstream oxygen sensor primarily checks whether the catalytic converter has failed. If the data fed back to the ECU by both sensors is the same, it indicates that the catalytic converter has failed. Upon failure, a warning light will illuminate on the car's dashboard to alert the driver. Meaning of ECU: ECU (Electronic Control Unit), also known as the "vehicle computer" or "onboard computer," is a specialized microcomputer controller for automobiles. Like a regular computer, it consists of a microprocessor (CPU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and other large-scale integrated circuits for shaping and driving. In simple terms, "the ECU is the brain of the car." After the catalytic converter fails: If the temperature is too high, the catalytic converter cannot function at normal temperatures. Its catalyst must be heated to a certain temperature to gain oxidation or reduction capabilities. Typically, the catalytic converter's light-off temperature is 250-350°C, and its normal operating temperature is 400-800°C. Chronic poisoning: The catalyst is highly sensitive to elements like sulfur, lead, phosphorus, and zinc. Sulfur and lead come from gasoline, while phosphorus and zinc come from lubricating oil. These four substances and their oxide particles formed during engine combustion easily adsorb onto the catalyst's surface, preventing it from contacting exhaust gases and thus losing its catalytic function—a phenomenon known as "poisoning." Carbon buildup: When the car operates at low temperatures for extended periods, the catalytic converter cannot activate, and soot from the engine exhaust adheres to the catalyst's surface, blocking contact with CO and HC. Over time, the carrier's pores become clogged, reducing its conversion efficiency. Exhaust deterioration: The catalytic converter has a limited capacity for pollutant conversion. Therefore, built-in purification technology must minimize the original exhaust pollutants. If the concentration and total amount of exhaust pollutants are too high—such as when the air-fuel mixture is too rich—it can impair the catalytic converter's conversion ability and efficiency. Oxygen transmission failure: To achieve optimal exhaust catalytic efficiency (over 90%), an oxygen sensor must be installed in the engine's exhaust pipe for closed-loop control. The oxygen sensor measures the oxygen concentration in the exhaust, converts it into an electrical signal, and sends it to the ECU, thereby keeping the engine's air-fuel ratio within a narrow, near-ideal range.

How to Deal with Oxidized Car Rearview Mirrors?

Prepare mineral materials with strong adsorption capabilities such as volcanic mud and alkaline earth, which have excellent deep-cleaning properties. Use cleaning items like scouring pads and cloths along with water to thoroughly wipe them clean. Utilize a polishing machine with professional fine wax for polishing treatment, aiming to achieve the maximum polishing rate and quickly remove the damaged layer caused by grinding. After polishing, wipe clean and immediately apply polishing wax with a cotton swab to the polished area, followed by immediate waxing to make the paint surface as shiny as a mirror.
