What are the reasons for frequent cycling of car air conditioning?

The reasons for frequent cycling of car air conditioning are: 1. Pressure issues: When the pressure in the air conditioning system exceeds 24 BAR or falls below 2.4 BAR, the pressure switch will control the compressor to stop. 2. Power issues: When the engine power is insufficient, the engine ECU controls the compressor to stop working via a relay. 3. Engine coolant temperature: When the coolant temperature is too high, the temperature control box controls the compressor to stop working via a relay. Below is related information: Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.

What is the difference between 200-cell and 300-cell catalytic converters?

The main difference between a 200-cell catalytic converter and a 300-cell catalytic converter lies in their pore size. The 300-cell converter has larger pores, which is considered the optimal parameter as it ensures passing the annual vehicle inspection while also improving the vehicle's power output when necessary. Additionally, the 200-cell converter produces relatively lower noise and emissions. More details are as follows: 1. The three-way catalytic converter is a crucial exhaust treatment device in automobiles, with at least one installed to process exhaust gases. Its primary function is to convert three harmful substances in vehicle exhaust—CO, HC, and NOx—into non-toxic, non-polluting gases such as CO, H2O, and N2. 2. There is also a cylindrical device inside which contains a purifying agent made of a carrier and catalyst, effectively purifying the gases as they pass through the cylindrical device.

What does fault code C0084 mean?

Fault code C0084 indicates a malfunction in the Traction Control System (TCS), and the fault code needs to be cleared. The function of the Traction Control System (TCS) is to control torque output by measures such as retarding ignition timing when it detects wheel slip, preventing the torque converter from locking up. When clearing the fault code, it is essential to follow the specified method for the particular vehicle model. Do not directly disconnect the negative battery cable, as this may lead to the following issues: 1. Some vehicle models' control modules may lose "historical records." Most central control modules have memory functions, and disconnecting the negative battery cable may erase engine operation data stored in the random-access memory. 2. Normal functions may be lost, such as the audio system's lock function, which would then require repair.

Below are the relevant provisions: 1. Article 92 of the "Road Traffic Safety Law" states that if a road passenger vehicle carries more passengers than the approved number, a fine of 200 to 500 yuan shall be imposed; if the number exceeds 20% of the approved number or if goods are carried in violation of regulations, a fine of 500 to 2,000 yuan shall be imposed. 2. If a freight motor vehicle exceeds the approved load capacity, a fine of 200 to 500 yuan shall be imposed; if the load exceeds 30% of the approved capacity or if passengers are carried in violation of regulations, a fine of 500 to 2,000 yuan shall be imposed. For the above two violations, the traffic management department of the public security organ shall detain the motor vehicle until the illegal status is rectified. 3. If a transport unit's vehicle falls under the circumstances described in the first or second paragraph of this article and fails to rectify after punishment, the directly responsible person in charge shall be fined 2,000 to 5,000 yuan.
