Why is the car air conditioning compressor particularly loud when turned on?

When the car air conditioning compressor is particularly loud, it is due to increased load. Introduction to the air conditioning compressor: The air conditioning compressor plays a role in compressing and driving the refrigerant in the air conditioning refrigerant circuit. The air conditioning compressor is usually installed in the outdoor unit. The air conditioning compressor draws refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant changes from a gaseous state to a liquid state, increasing the pressure. Working principle: The heating principle is the same as the cooling principle, which is the reverse Carnot cycle. The difference from the cooling principle is the exchange of the condenser and evaporator, namely: compressor-evaporator-throttling device-condenser.

What kind of engine oil is better for turbocharged engines?

Turbocharged engines are better suited for full synthetic or semi-synthetic engine oil. Compared to naturally aspirated engines, turbocharged engines generate more powerful performance and higher output during operation, leading to relatively greater wear on internal components. Without high-performance engine oil for lubrication, it can result in abnormal wear or severe coking of the turbocharger, and in severe cases, even damage the turbo. There are three types of engine oils used in vehicles: mineral oil, semi-synthetic oil, and full synthetic oil. These three types of oils serve different purposes and have varying service intervals. Generally, mineral oil has a service interval of about 5,000 kilometers, semi-synthetic oil about 6,500 kilometers, and full synthetic oil about 10,000 kilometers.

What Causes Pungent White Smoke from Exhaust?

Reasons for pungent white smoke from exhaust: 1. The vehicle's air filter is contaminated, causing insufficient air intake; 2. The carburetor is malfunctioning, or the oxygen sensor in the exhaust pipe is contaminated, preventing the computer from providing correct air-fuel mixture information; 3. The engine's piston is damaged and burning engine oil; 4. Excessive water content in gasoline. It is recommended to clean the throttle body and check for leaks at the junction of the cylinder head and gasket. If leaks are found, it can be determined as caused by a damaged cylinder gasket. White smoke during cold starts that disappears as the engine warms up is normal, as it results from complete combustion in the engine and hot steam encountering cold air.

When will Guangdong implement China VI emission standards?

Guangdong implemented the China VI emission standards on July 1, 2019. Below is relevant information about China VI: 1. Concept of China VI: The term refers to vehicle emission standards that meet the requirements of the sixth stage of national emission standards, commonly abbreviated as China VI. This national vehicle emission standard began phased implementation starting from late 2019. China's vehicle emission standards are modeled after European standards, with the latest being the sixth stage emission standard, which is more stringent with progressively lower limits for various harmful gases. 2. Vehicle emission standards: These regulations specify limits for harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. The purpose of establishing vehicle emission standards is to curb the production of these harmful gases, encouraging automobile manufacturers to improve emission standards and reduce harmful emissions.
