Why Can't You Turn on the Air Conditioning When the Car is Parked?

The following are specific reasons why you cannot turn on the air conditioning: 1. High fuel consumption: Keeping the air conditioning on while the car is idling consumes a lot of fuel because the compressor relies on the engine idling, which leads to incomplete combustion of gasoline and easily causes carbon buildup. 2. Toxic substances: Incompletely burned gasoline produces toxic substances such as carbon monoxide. If the car doors and windows remain closed for a long time, these exhaust gases can enter the enclosed cabin and accumulate to a level that can cause carbon monoxide poisoning. Idling with the air conditioning on emits more harmful exhaust gases than driving with the air conditioning on, as the idling condition produces relatively higher amounts of harmful gases like carbon monoxide, hydrocarbons, and nitrogen oxides.

What Are the Causes of Engine Block Cracking?

There are many reasons that can cause engine block cracking, such as adding water instead of antifreeze to the radiator. When the outside temperature is too low, the water inside the engine block freezes, causing the block to crack. Engine water shortage, overheating, and then adding too much cold water directly or splashing cold water onto the engine can cause the engine block to crack due to thermal shock. Severe impacts can also lead to cracks in the engine block. Engine Connecting Rod Fracture: Water entering the engine cylinders can cause the connecting rods to break. When a vehicle drives through flooded roads, water can be sucked into the cylinders. The water initially entering the cylinders quickly turns into steam due to the high temperature of the block, making it impossible for the cylinder to form a combustible mixture. As more water enters, it accumulates on top of the piston, reducing the effective volume of the combustion chamber and increasing compression resistance, which in turn increases the pressure transmitted from the piston to the connecting rod. When the water volume reaches a certain level, the compression stroke essentially becomes compression of water, drastically increasing the pressure on the connecting rod, causing it to bend, deform, and eventually break, potentially even rupturing the engine block. Repair Methods: To repair a cracked engine block, use coarse sandpaper to remove rust around the crack. When sanded to a certain extent, the terminal point of the crack can be identified. Then, directly weld a repair plate, but be cautious of warping at the welded area. If warping occurs, it must be hammered while hot to prevent residual slag. After repair, place an asbestos gasket between the repair plate and the block, and apply a layer of lubricating oil on both sides.

How to Determine the Condition of Engine Valves?

Check the condition of the valve head to the valve stem using the following methods: 1. Pitting on the valve seat; 2. Insufficient valve margin thickness; 3. Bent valve stem; 4. Pitting or severe wear on the valve stem; 5. Wear on the valve lock key groove; 6. Wear on the valve stem end. Additional relevant information is as follows: 1. Proper valve maintenance is crucial for engine performance. Therefore, it is essential to follow all measurement procedures in detail to identify components that exceed specifications. 2. If the measurement procedure indicates that the valve or valve seat requires reconditioning, the measurement procedure should be performed again after reconditioning.

What does ETC at highway entrance mean?

ETC at highway entrance refers to the Electronic Toll Collection system, which is an automatic tolling system for highways or bridges. The fully automatic electronic toll collection system is one of the service functions of the intelligent transportation system, and it is particularly suitable for use on highways or in busy bridge and tunnel environments. Currently, there are dedicated ETC toll lanes at highway toll stations. Car owners only need to install a sensor card on the vehicle's front windshield and preload funds. When passing through the toll station, there is no need for manual payment or stopping, as the highway toll will be automatically deducted from the card, enabling automatic toll collection. The fully automatic electronic toll collection system requires the installation of an onboard unit containing vehicle information on the vehicle.

How many more years can a China 5 vehicle be driven if purchased now?

China 5 vehicles can be driven until they are scrapped, as there is no mandatory retirement period set for private passenger vehicles in China. Therefore, how long a China 5 vehicle can be driven depends on whether it meets the standards at the time of purchase. If it complies, it can be driven indefinitely. Methods to check the emission standard of a vehicle: 1. Check the vehicle's environmental protection label: The simplest and most direct method is to look at the vehicle's environmental protection label, which clearly indicates the emission standard on the back. 2. Website inquiry: Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to check. 3. Vehicle Management Office inquiry: Take the vehicle registration certificate (original or copy) to the local Vehicle Management Office for inquiry. 4. Vehicle manufacturing certificate: For new vehicles, you can refer to the vehicle manufacturing certificate to find the emission standard. However, generally, the certificate is kept at the Vehicle Management Office. Therefore, it is recommended to make a copy for your records when purchasing a new vehicle.
