Does the jerky movement of the fuel nozzle cause fuel loss. Reasons for fuel loss: After testing by professionals, it has been proven that the repeated tightening and releasing of the fuel nozzle can cause gasoline backflow, which indeed results in reduced fuel delivery. Although this mechanism is designed to prevent overflow during refueling, it does lead to decreased fuel quantity. This occurs because frequent on-off operation of the throttle causes data recording lag in the nozzle's switch valve - meaning the meter starts counting before fuel actually flows out. After shutting off the nozzle, un-dispensed fuel begins flowing backward, creating significant measurement errors. Definition of fuel nozzle: The fuel nozzle is the terminal output device of gas station dispensers that interfaces with vehicle fuel tanks. The most commonly used types are self-sealing nozzles and composite nozzles.

ETC will incur a service fee if not used for a year. Here are the relevant details: 1. Reason: Currently, although the ETC cards issued by major banks do not impose a minimum annual spending requirement on vehicle owners, they still require a certain number of transactions to waive the annual fee. Additionally, fees such as SMS service charges and card loss handling fees must also be paid by the vehicle owner. 2. Billing System: The system utilizes dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations.

What Does Driving License Subject 3 Test?

Subject 3 road driving skills test generally includes: preparation before getting on the car, light simulation test, starting, driving in a straight line, shifting gears up and down, changing lanes, pulling over, going straight through intersections, turning left at intersections, turning right at intersections, passing crosswalks, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and night driving. The difficulties of the Subject 3 test are as follows: 1. Speed and gear mismatch: Errors regarding high gear at low speed and low gear at high speed should be noted during the test. Before shifting gears, it is necessary to increase or decrease the speed to match the gear, and then switch gears. 2. Deviation in straight-line driving: Many trainees deliberately slow down the speed during driving because they are worried that the driving trajectory is not straight, which is not advisable. This will instead increase the possibility of the vehicle's driving trajectory deviating, so a reasonable and constant speed should be maintained.
