Can the car proceed when the left-turn waiting zone light turns red?

When the light turns red in the left-turn waiting zone, the car cannot proceed. Here are the relevant explanations: 1. The purpose of the left-turn waiting zone: The left-turn waiting zone is only for vehicles making a left turn. When the straight-through light in the same direction is green, although the left-turn light is red, vehicles making a left turn are allowed to enter the left-turn waiting zone at the intersection and wait until the left-turn signal turns green before proceeding through the intersection. The left-turn waiting line is not a "stop line"; if both the straight-through and left-turn signal lights are red, vehicles must wait at the previous stop line. 2. Relevant advice: It is recommended to slow down in advance when approaching an intersection to create distance from larger vehicles, allowing time and space to observe the traffic lights. If you have already crossed the stop line, do not reverse, as this not only increases the risk of collision with vehicles behind or pedestrians but may also be recorded by traffic cameras due to the movement.

What kind of vehicle is used for pouring concrete?

Concrete pouring vehicles are called concrete pump trucks. The following is an introduction to concrete pump trucks: 1. Introduction to concrete pump trucks: These are machines that use pressure to continuously transport concrete through pipelines. They consist of a pump body and delivery pipes. Based on structural types, they are categorized into piston-type, extrusion-type, and hydraulic diaphragm-type. The pump body is mounted on a vehicle chassis, and when equipped with an extendable or foldable placing boom, it forms a pump truck. Concrete pump trucks are modified from heavy-duty truck chassis, with the chassis fitted with motion and power transmission devices, pumping and mixing devices, placing devices, and other auxiliary equipment. The power of the concrete pump truck is transmitted from the engine to the hydraulic pump group or rear axle through a power take-off box, and the hydraulic pump drives the piston to operate the concrete pump. The placing boom and delivery pipes on the pump truck are then used to transport concrete to a certain height and distance. 2. Classification of concrete pump trucks: They consist of five main parts: the boom, pumping system, hydraulic system, support system, and electrical control system.

What is the principle of the throttle valve?

The throttle valve is used to regulate the engine speed. The larger the throttle opening, the lower the speed. There is an air intake hole next to it. When the throttle angle is large, the air pressure inside the engine is less than that outside, and part of the air enters through the small hole on the side, carrying away the corresponding gasoline. In other words, the smaller the throttle opening, the more gasoline is carried away. The throttle valve is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. It is connected to the air filter at the top and the engine block at the bottom, and is known as the throat of the car engine. There are two types of throttle valves: the traditional cable type and the electronic throttle. The throttle control mechanism of a traditional engine operates through a cable (soft steel wire) or a rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, thereby adjusting the amount of air intake.
