The fuel pump is installed inside the fuel tank. Its function is to draw gasoline from the fuel tank and deliver it through pipelines and the fuel filter to the float chamber of the carburetor. Thanks to the fuel pump, the fuel tank can be placed at the rear of the vehicle, away from the engine and at a lower position. Fuel pumps can be divided into two types based on their driving methods: mechanically driven diaphragm type and electrically driven type. The diaphragm fuel pump is representative of mechanical fuel pumps, used in carburetor engines and driven by an eccentric wheel on the camshaft. The electric fuel pump, on the other hand, is not driven by the camshaft but relies on electromagnetic force to repeatedly move the pump diaphragm. This type of electric pump allows for flexible installation positions and helps prevent vapor lock.

How Early Should You Arrive for the Subject 2 Driving Test?

Subject 2 test candidates must arrive at the test site at least 1 hour before the scheduled start time for verification and entry. Social vehicles are prohibited from entering the test site. Subject 2 Test Content: For the Subject 2 driving test, the requirements for pole parking and garage shifting, as well as test items with limited real-life applicability such as passing continuous obstacles and single-plank bridges, have been removed. After adjustments, the original "train ten items, test four items" has been changed to "train and test five items each," which include reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves. Important Notes: Test Scheduling: The Subject 2 test requires advance scheduling. Applicants can self-schedule the test via the internet or phone, increasing the methods for test scheduling. This makes it more convenient for the public to schedule test times based on their study, work, and personal arrangements, avoiding the need to queue at the vehicle management office. Test Attempts: After scheduling the Subject 2 test, applicants can take the test once and have one retake. Those who do not attend the retake or fail the retake must reschedule the test. Within the validity period of the test permit, the number of scheduled attempts for the Subject 2 test must not exceed five. Passing Criteria: The test is scored out of 100 points, with evaluation standards set for failing, deducting 100 points, and deducting 10 points.

How many days does it usually take to get the license after passing the test?

After passing the test, the time to obtain the driver's license is divided into two time nodes: same-day issuance and next-day issuance. In some areas, generally after passing all the driving test subjects, the vehicle management office will process the license within one working day, and you can even get the license two hours after the test. The specific time to receive the license may vary by region, so you can consult your instructor for details. Below are some notes about receiving the license: Same-day issuance: If you finish the subject four test early in the morning, you can collect the driver's license at the vehicle management office in the afternoon. However, more and more vehicle management offices have canceled the on-site license collection process, meaning you cannot get the license on the same day. The advantage of same-day issuance is that you get the license quickly and can have it as early as possible. The disadvantage is that you may have to wait for a long time at the vehicle management office, which can be time-consuming. Next-day issuance: In this case, the student does not need to go to the vehicle management office. Instead, the driver's license is mailed via same-city courier. After passing subject four, the vehicle management office staff will ask you to fill in the mailing address and contact phone number. Once the license is processed on the test day, a courier will deliver it within the same city. Due to the short distance, the license will be mailed to the student the next day. However, this mailing method requires the student to pay the courier fee.

What procedures are required to convert a commercial vehicle to a non-commercial vehicle?

To apply for converting a commercial vehicle to a non-commercial vehicle, the required documents include an application form, the 'Road Transport Permit' (including the payment receipt) for the conversion from commercial to non-commercial use, and the commercial vehicle license plate. If these cannot be submitted, a lost property declaration procedure must first be completed. Specific steps: First, submit an application to the local Transportation Bureau's Vehicle Management Office or Transportation Management Office to obtain the quota or approval for converting a non-commercial vehicle to commercial use. Then, proceed to the Vehicle Management Office to complete the relevant procedures and change the vehicle's usage type. After that, go to the Transportation Management Department to cancel the commercial vehicle permit. Once canceled, the vehicle can no longer be used for commercial purposes, and the annual inspection of the vehicle license will follow normal procedures. When converting a commercial motor vehicle to a non-commercial motor vehicle or vice versa, or when the owner's residence changes beyond the jurisdiction of the Vehicle Management Office, an application for change of registration must be submitted to the Vehicle Management Office after the change, along with the required legal documents and certificates.

Where is the best position for a Corolla phone holder in 2020?

When looking for a suitable position to install a phone holder in a Corolla, the key is to align with common usage habits. The most common installation location is on the car's air vent. Benefits of car phone holders: When traveling, mobile phones are naturally inseparable companions, even during driving. For car owners, the placement of the phone while driving has always been awkward. Although many cars are designed with ample space reserved for phones, sudden incoming calls or the need to use phone navigation while driving can still be inconvenient. In such cases, car phone holders come into play. Simply fixed on the dashboard or air vent, they serve as practical tools to assist driving while also adding a nice decorative touch. Silicon suction cup holder: It adopts the triangular fixation principle formed by the phone arm clip, which can securely lock the phone in place, preventing it from falling even on bumpy roads. At the same time, thanks to the high-quality silicon suction cup, it has strong adhesion. Based on actual store test data, it can bear up to 13KG of weight, making holding a phone effortless. Moreover, the silicon suction cup can be reused multiple times—after washing with water and air-drying, its suction power remains as strong as new. The contact surface with the phone is equipped with a silicon cushion, providing all-around anti-slip and anti-scratch protection to effectively prevent slipping and falling.
