What is the maximum speed limit for a car when turning?

The maximum speed for a car when turning or making a U-turn should not exceed 30 kilometers per hour. Below is a detailed introduction about vehicle speed: 1. Overview: Vehicle speed refers to the distance a car travels per unit of time, abbreviated as speed, commonly measured in kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. 2. Others: Vehicle speed can also generally refer to the speed of motor vehicles. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a car passing a specific point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and to ensure their coordination.

How Long Can You Drive with a Blown Cylinder Head Gasket?

Cylinder head gasket failure generally means you should not continue driving. It is recommended to drive to the nearest repair shop for servicing or call for roadside assistance. The cylinder head gasket is used to seal the water jacket and cylinder liner. A blown gasket will compromise this seal, allowing coolant from the water jacket to enter the cylinder liner while combustion gases leak into the cooling system. This leads to two issues: coolant loss and overheating (since hot combustion gases entering the cooling system raise coolant temperature). Main symptoms of a blown head gasket include: 1) Coolant bubbling in the radiator with rising temperature and white exhaust smoke. 2) Engine oil emulsification (turning milky white) or oil entering combustion chambers, causing blue exhaust smoke. 3) Noticeable power loss during driving, reduced acceleration, and in severe cases, engine knocking sounds. For safety reasons, immediate gasket replacement or repair is necessary.

What Causes a Car Air Conditioner to Not Cool?

There are several reasons why a car air conditioner may not cool properly: 1. Low refrigerant level: Refrigerant loss is mainly due to leaks. If the air conditioner performs poorly and the issue recurs after refilling the refrigerant, pay attention. If the condenser is leaking, it needs to be replaced. 2. Damaged air conditioner flap: Flap motor failure is relatively rare but not unheard of. If the flap motor malfunctions, it becomes problematic. The flap motor is usually located in the lower middle part of the dashboard and serves as the master switch for the air vents. A broken switch means that even if the air conditioner can produce cold air, the air can only escape through gaps. If no air comes out from any vents when the air conditioner is turned on, be cautious. Replacing the flap motor requires dismantling the dashboard, which is a major task. 3. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. In spring, willow and poplar catkins can clog the condenser, causing the engine to overheat or the air conditioner to perform poorly. Therefore, always check if the radiator is clogged with these fibers during spring. When cleaning, make sure to first use an air gun to blow away the debris before using a water gun to wash, otherwise it may have the opposite effect, leading not only to poor air conditioning performance but also increased fuel consumption.

Where to Get a Key Duplicated?

You can get a car key duplicated at a 4S shop or a large repair shop. Here is the relevant information: 1. Types of keys: Currently, car keys are divided into two types, one without an anti-theft chip and the other with an anti-theft chip. Keys without an anti-theft chip are commonly found in some low-end models and don't even have a remote control, which is now almost rare. Since it is a mechanical key without an anti-theft chip or remote control, duplicating this type of key is very convenient and quick. 2. Principle: Keys with an anti-theft chip are naturally much more advanced. In addition to the mechanical key part being correct, the key also needs to be reprogrammed so that the code of the key chip completely matches the code of the engine anti-theft system to start the engine. Duplicating this type of key is relatively complicated, and it can also be done at large repair shops outside, with relatively cheaper prices. If you want professional service, go to a 4S shop, where the price is higher and it takes longer.

Is Full-Range Speed Detection Really Full-Range?

Full-range speed detection is not truly full-range. Related details are as follows: 1. Specific Methods: The traffic management departments of public security authorities rely on fixed highway capture systems, supplemented by mobile speed detection enforcement equipment, adopting a combination of continuous interval speed detection, single-point fixed speed detection, and regional mobile speed detection for enforcement. 2. Precautions: The traffic police department states that highway speed detection is entirely based on the speed limits marked by the transportation departments on highways. For sections without speed limit signs, enforcement follows the statutory maximum speed limit as prescribed by national law, with the maximum speed for small vehicles set at 120 km/h. In special speed limit sections, the transportation department will set up speed limit signs in advance, and drivers are advised to pay attention to the warning signs while driving.

What Causes High Low Pressure in an Automotive Compressor?

Reasons for high low pressure in an automotive compressor: Compressor damage; Excessive opening of the expansion valve (refers to excessive opening caused by valve body failure, such as loose adjustment spring, faulty temperature sensing bulb, etc.); Poor system design, such as an undersized compressor, oversized expansion valve selection, excessive flow resistance in the evaporator, excessive flow resistance in the low-pressure pipe, etc.; Poor heat dissipation in the condenser, lack of subcooling before refrigerant enters the evaporator leading to poor heat exchange efficiency in the evaporator. Relevant information about turbochargers is as follows: 1. Introduction: A turbocharger is essentially an air compressor that increases air intake by compressing air. 2. Working Principle: It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller compresses air delivered through the air filter pipe, pressurizing it into the cylinders. When the engine speed increases, the exhaust gas velocity and turbine speed also increase synchronously, allowing the impeller to compress more air into the cylinders. The increased air pressure and density enable the combustion of more fuel, thereby increasing fuel supply and adjusting the engine speed, which enhances the engine's output power.
