What are the causes of unstable idle speed when the engine is warm?

The following are the main reasons for unstable idle speed when the engine is warm: 1. Poor performance of spark plugs. 2. Faulty throttle position sensor. 3. Air leakage in the intake system. 4. Vacuum tube leakage. 5. Malfunction of the idle stepper motor and idle control valve warning light. Here are some solutions to these issues: If unstable engine idle speed is detected, the first step is to adjust the idle speed. If the problem persists after adjustment, check whether the idle jet and idle air jet are clogged. If clogging is found, clean them with gasoline or acetone and then use compressed air to blow them clear. If no clogging is found, inspect the intake manifold or carburetor for air leaks. If leaks are present, tighten the screws to secure them.

How many kilometers can a 48V electric vehicle run?

Here are the main factors affecting the range of an electric vehicle's battery: 1. Ambient temperature: When the ambient temperature drops, the battery's usage time will correspondingly decrease. According to empirical calculations, for every 1°C drop in room temperature, the battery capacity decreases by about 1%, which is why electric vehicle batteries have shorter usage times in winter. 2. Depth of discharge: Depth of discharge refers to the extent of battery usage during electric vehicle riding. The deeper the discharge depth each time, the shorter the battery's lifespan. Simply put, the longer the electric vehicle is used after a full charge, the greater the battery's discharge depth. 3. Road traffic conditions: Generally, on flat roads, if there are more steep slopes, the distance traveled will decrease. 4. Actual conditions such as load weight and frequency of starting and braking. 5. Charging time of the electric vehicle battery: The charging method for the electric vehicle battery is very important, as improper operation can damage the battery.

What Causes Windshield Washer Fluid Not to Spray in Winter?

In winter, the most common reason for windshield washer fluid not spraying is that the added fluid lacks sufficient antifreeze capability and freezes. For example, in winter temperatures around -10°C, a washer fluid with a freeze resistance of 0°C is typically used. Other causes include clogged windshield nozzles, damaged washer pump or electrical faults, leaks in the washer fluid lines, or insufficient washer fluid levels. It is recommended to choose a washer fluid with antifreeze capability of at least -25°C or -40°C based on the winter driving environment. Here are the correct ways to use windshield washer fluid: 1. Spray it on the area to be cleaned, let it soak for 2-3 minutes, then wipe with a soft cloth or directly apply the cleaning solution with a soft cloth until the area is clear. 2. For heavily soiled areas, repeat the cleaning process and rinse with clean water, then dry thoroughly. 3. After dilution, it can be directly poured into the vehicle's windshield washer reservoir for use while driving.

How to Install Piston Rings?

If no special clamp is available, you can also use both thumbs to appropriately open the piston ring port, while the other four fingers protect the surrounding area of the ring. Carefully slide the ring into the piston ring groove, paying attention to the structure and installation direction of each ring. Make sure to distinguish the front and back sides. During installation, the inner circular cut groove and chamfered groove should face upward; the outer circular cut groove and chamfered groove should face downward.

Is It Necessary to Install Rain Guards?

During rainy days, the car interior can feel stuffy, and even turning on the air conditioning doesn't provide much relief. Opening the windows allows rainwater to splash inside. Installing rain guards can solve this problem. Although the windows can only be opened slightly, it's enough to allow fresh air to circulate and expel the stale air inside the car. Additionally, rain guards offer some sunshade benefits, preventing side sunlight from obstructing the driver's view. The installation method for rain guards is as follows: 1. First, thoroughly clean your car, especially the areas where the rain guards will be installed (door frames), to ensure no debris interferes with proper adhesion. 2. Compare the rain guards with the door frames to ensure the correct positioning and size. 3. Once confirmed, peel off the 3M adhesive backing on the rain guards and attach them to the door frames. 4. Finally, press the rain guards firmly back and forth with your hands to ensure they are securely fixed. Alternatively, you can use a hairdryer to heat the adhesive for better bonding.
