It may be due to a faulty fuel pump in the new car, but generally, it is not recommended to replace the fuel pump in a new car. Introduction to the fuel pump: The fuel pump is a lightweight and compact pump, mainly categorized into in-line, distributor, and single-unit types. The fuel pump requires a power source to operate, and its lower camshaft is driven by the engine crankshaft gear. Impact of replacing the fuel pump in a car: When the pump core is damaged, during the operation of the fuel supply system, there will be no sound of the fuel pump running when the ignition is turned on. When the pump body is damaged, due to pressure leakage, the fuel pressure cannot reach the specified value, leading to poor atomization and consequently, the engine failing to start.

Can not wearing a seat belt be captured?

Electronic eyes can capture images of people not wearing seat belts. Related knowledge about electronic eyes: 1. Definition: "Electronic eye" is the common name for the "Intelligent Traffic Violation Monitoring and Shooting Management System". 2. Purpose: Electronic eyes use various technologies such as vehicle detection, photoelectric imaging, automatic control, network communication, and computers to monitor violations such as running red lights, driving in the wrong direction, speeding, crossing lines, and illegal parking around the clock. They capture graphic and textual information of vehicle violations and conduct post-processing based on the violation information. 3. Working principle: Electronic eyes use induction lines to sense the pressure transmitted by cars on the road. The signals are collected by sensors and sent to the central processor, which temporarily stores them in a register (this data is valid within one red light cycle).

Is a 1.5L engine sufficient for highway driving?

A 1.5L engine is sufficient for highway driving, but the following points should be noted: 1. Maintain a moderate speed, preferably around 120 km/h. 2. If you frequently drive long distances on highways, engage in off-road operations, or drive on mountainous roads, it is advisable to opt for a slightly larger engine displacement. Additional information: 1. Displacement (Swept-volume): A specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Generally, a larger displacement means the engine releases more energy per unit time (converting chemical energy from fuel into mechanical energy), resulting in better "power performance." 2. Pre-highway checks: Inspect vehicle lights, tire pressure, acceleration, braking, clutch pedal, seat belts, steering performance, brake fluid level, coolant level, engine oil level, and windshield washer fluid level.
