Why does the Magotan shake and stall during cold start?

Magotan shaking and stalling during cold start may be caused by the following reasons: 1. Low temperature: Insufficient temperature in the engine leads to inadequate fuel and lubricant temperatures. During cold starts, more fuel injection is required to meet power demands. Larger spark plug gaps result in weaker ignition energy. Poor fuel atomization at low temperatures requires higher ignition energy. Prolonged vehicle use can cause spark plug gaps to widen, reducing ignition energy and affecting power performance, leading to shaking. 2. Incorrect air-fuel mixture ratio: Inaccurate fuel-air mixture occurs in both open-loop and closed-loop control systems. In closed-loop control vehicles, the oxygen sensor's minimum operating temperature is 370°C. If the exhaust pipe temperature doesn't reach 370°C upon startup, the oxygen sensor won't function. This causes ECU miscalculations, resulting in errors in fuel-air mixture and ignition timing control, reducing power output and causing shaking. 3. Faulty coolant temperature sensor: The coolant temperature sensor is crucial for the ECU to determine engine operating conditions. If the engine starts at -10°C, the ECU may inject fuel based on a 20°C condition, resulting in insufficient fuel quantity and consequent shaking.

What Causes Abnormal Noises in the Car Air Conditioning?

When the car air conditioning produces abnormal noises, it is necessary to determine whether the noise is coming from inside or outside the air conditioning system. Abnormal noises inside the air conditioning system are often caused by moisture or air in the refrigerant. When the refrigerant expands, it can produce sounds, and the refrigerant can be directly replaced. Below is an analysis of common causes of car air conditioning issues: 1. Problems with the compressor electromagnetic clutch: Issues with the compressor electromagnetic clutch are a common cause of abnormal noises in the compressor. Since the compressor frequently operates under high load, transitioning from low to high speeds, the demands on the electromagnetic clutch are high. Additionally, the electromagnetic clutch is usually installed close to the ground and often comes into contact with rain and dirt. When the bearings inside the electromagnetic clutch are damaged, abnormal noises can occur. 2. Issues with the tightness of the compressor drive belt: The tightness of the compressor drive belt can also cause abnormal noises in the car air conditioning compressor. If the drive belt is too tight or too loose, it can affect the lifespan of the electromagnetic clutch. A loose drive belt can cause the electromagnetic clutch to slip, while an overly tight drive belt increases the load on the electromagnetic clutch.

How many copies of the vehicle frame number rubbing are required for new car registration?

New car registration requires 2 copies of the vehicle frame number rubbing. The vehicle frame number, also known as the Vehicle Identification Number (VIN), is a unique 17-character alphanumeric code that represents various vehicle information. Car registration process: After selecting the vehicle model and paying the purchase price, the dealer will provide the manufacturer's vehicle quality certificate and a 3-day vehicle movement permit, and issue the purchase invoice. When issuing the purchase invoice, the owner needs to provide their name and ID number. The owner should bring the tax payment copy of the purchase invoice, a copy of the vehicle quality certificate, original ID card and its copy (for corporate vehicles, the company's organization code certificate and official seal are required) to the vehicle purchase tax office to pay the additional vehicle purchase tax. After completing the vehicle purchase tax payment, the owner can submit the relevant documents, including the registration copy of the purchase invoice, original vehicle quality certificate, original ID card and its copy (must be copied on A4 paper) to the vehicle management office for approval and license plate application. At the vehicle management office, first obtain a new vehicle registration form (for corporate vehicles, an official seal is required), accurately fill in the owner and vehicle information (with guidance available), then queue to submit. The vehicle will undergo an external inspection to verify the engine number, frame number, and vehicle model. After the external inspection, proceed to the insurance hall to purchase compulsory traffic insurance and other commercial insurance. After completing the insurance, process the vehicle registration at the registration hall. Pay relevant fees including vehicle and vessel tax, road toll, vehicle license, and license plate fees. After paying the fees, the owner can randomly select their license plate number via computer. After selecting the number, the license plate can be installed. After installation, take photos of the new vehicle for records. Apply anti-theft glass markings and obtain the exhaust emission certificate. The final step at the vehicle management office is to collect the vehicle license and vehicle registration certificate (title). The owner should bring the vehicle license, vehicle purchase tax payment certificate, and vehicle registration certificate to the vehicle purchase tax office to collect the tax booklet. Finally, register and pay the road maintenance fee at the road maintenance fee collection office with the registration copy of the purchase invoice, vehicle license, tax booklet, and vehicle registration certificate.

What Happens When Car Air Conditioning Pressure is Too High?

High pressure in a car's air conditioning system can lead to reduced cooling efficiency, increased working pressure on the compressor causing it to overheat, and may result in the compressor not working or operating intermittently. Below is the working process of a car's air conditioning system: 1. Compression Process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas before discharging it. 2. Heat Dissipation Process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant amount of heat. 3. Throttling Process: The refrigerant liquid, which is at a higher temperature and pressure, passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply, exiting as a mist (fine droplets). 4. Heat Absorption Process: The mist-like refrigerant liquid enters the evaporator, where, because the refrigerant's boiling point is much lower than the temperature inside the evaporator, it evaporates into a gas. During this evaporation process, it absorbs a large amount of surrounding heat, after which the low-temperature, low-pressure refrigerant vapor re-enters the compressor.

What does 'please check power steering' mean?

Please check power steering means there is a fault with the power steering system. Below are common faults and causes in automotive steering systems: 1. Abnormal noise during steering: This is usually caused by mechanical issues such as damage to the kingpin and bushing, or failure of the column thrust bearing. During inspection, turn the steering wheel left and right to locate the source of the noise for disassembly and repair. 2. Steering gear oil leakage: Oil leakage from the steering gear typically occurs at a few locations: the upper cover of the steering gear, the side end cover, and the connection between the steering shaft and the pitman arm. These areas are equipped with seals, and replacing the oil seals and gaskets can resolve the issue. Leakage from other parts may indicate sand holes or cracks in the steering gear housing. Small cracks and sand holes can be sealed using Loctite 290 high-permeability sealant. 3. Difficulty in steering wheel return: Most vehicles have an automatic return function for the steering wheel. In hydraulically assisted vehicles, the automatic return function may be slightly weakened due to hydraulic damping, but some return capability should remain. If the same amount of force is required to return the steering wheel as when turning, it indicates a fault in the return function, which is usually related to the mechanical parts of the steering system.
