What are the symptoms of engine misfire in a car?

The symptoms of engine misfire in a car include unstable idle speed, abnormal engine shaking; noticeable decrease in power; difficulty in starting the vehicle, engine prone to stalling; black smoke from the exhaust pipe. The following are the causes and solutions for misfire: Ignition system issues such as eroded spark plugs not firing, damaged high-voltage coils unable to generate high voltage, faulty high-voltage coil relays, or possible ECU malfunctions causing the high-voltage coils not to ignite. Solutions include timely replacement of spark plugs as per the maintenance manual, using a multimeter to check if the high-voltage coil resistance is normal, and professional decoding equipment at a 4S shop for further diagnosis. Fuel injection system problems like insufficient fuel supply pressure, damaged fuel lines, excessive wear of the fuel tank pump, clogged fuel filters, insufficient pressure from the high-pressure fuel pump, clogged or poorly atomizing fuel injectors, or excessive wear of the injector needles leading to fuel dripping, which causes excessive gasoline vapor in the cylinder wetting the spark plugs and preventing them from firing. Solutions include using a fuel pressure gauge to check if the fuel line pressure is adequate; inspecting the fuel tank pump and high-pressure fuel pump for excessive wear and replacing them if necessary; cleaning or replacing fuel injectors based on usage.

Is it okay to run the air conditioning while parked on the roadside?

Running the air conditioning while parked is not advisable as it poses significant risks, including potential carbon monoxide poisoning. When the engine operates at idle for extended periods, incomplete combustion of gasoline occurs, producing high concentrations of carbon monoxide. In poorly ventilated areas like garages, this gas can enter the vehicle and cause poisoning. Below are the impacts of running the air conditioning while parked: 1. Impact on engine lifespan: Idling the engine to power the air conditioning at low RPMs reduces oil pump pressure, leading to insufficient lubrication of engine friction surfaces and accelerated wear. Additionally, low engine speeds can cause reduced intake pressure, prompting the engine to increase throttle opening and fuel injection. This results in incomplete combustion, carbon buildup in the combustion chamber, and ultimately shortens engine life, leading to issues like difficulty starting, poor acceleration, and increased fuel consumption. 2. Impact on battery lifespan: When idling the car to run the air conditioning, the cooling and ventilation systems driven by the air conditioning motor consume substantial electrical power, as does the vehicle's electronic control system. Since idling generates limited electricity, the engine often cannot meet these demands, forcing the battery to compensate. Over time, this drains the battery's charge capacity and reduces its effective service life.

What kind of adhesive is used for car spoilers?

Car spoilers use 3M double-sided adhesive tape. 3M tape provides strong adhesion for spoilers, but illegal modifications are against the law. There are two methods for fixing car spoilers, generally categorized as destructive installation and non-destructive installation. Non-destructive installation involves directly using 3M tape for adhesion; destructive installation requires drilling holes in the trunk lid and then securing the spoiler with screws. This method provides the strongest hold, but if not done properly, it can easily lead to rusting of vehicle body panels and requires higher craftsmanship. Spoilers installed with adhesive cannot pass annual vehicle inspections. Whether adhered or reinforced with nuts and bolts, spoilers are considered illegal modifications to the vehicle's appearance, which is a violation of the law. Such modifications can affect road safety and pose threats to other road users. Vehicle modifications must strictly comply with national laws and regulations, which clearly specify requirements for both appearance and performance modifications. Generally, owners can replace front and rear bumpers or grilles, but the size of these components must not exceed the original vehicle dimensions. For color changes, except for certain prohibited colors, owners simply need to register the new color with the vehicle management office.

Why Does It Smell Strongly of Gasoline While Driving?

When there is a strong gasoline smell while driving, the reasons are as follows: 1. Insufficient air intake in the car's throttle body leads to incorrect air flow information, affecting fuel injection volume, increasing fuel consumption, and resulting in a stronger gasoline smell. 2. Excessive carbon deposits in the cylinder combustion chamber and pistons cause insufficient cylinder pressure, leading to an overly rich air-fuel mixture and increased fuel consumption. 3. Excessive carbon deposits inside the engine result in poor atomization of the air-fuel mixture. 4. Leakage in the gasoline pipe forms oil sludge at the pipe joints, and the smell enters the car through the air conditioning system. 5. In older cars, rubber pipes in the engine compartment are prone to aging, leading to leaks. If you notice a strong gasoline smell when starting the car and the smell persists, you can check the condition of the fuel pipes.

Is the Water Dripping from the Car Chassis from the Air Conditioning?

When the air conditioning is turned on in summer, the water dripping from the chassis is from the air conditioning system. However, if water drips from the chassis even when the air conditioning is not in use, it indicates a coolant leak in the cooling system, and immediate repair of the car's cooling system is required. The dripping position of the car air conditioning system is located slightly to the right of the middle of the front of the car. The dripping caused by the car air conditioning refers to the condensation of moisture in the cabin on the evaporator during operation, forming water droplets that are discharged outside the car through the drain pan and drain pipe. In this case, the dripping is a normal phenomenon. Water dripping from the car chassis can be attributed to the cooling system of the box, windshield washer fluid, or condensation water generated during air conditioning use. The amount of water discharged from the air conditioning is related to the environmental humidity. Higher environmental humidity increases the condensation water on the evaporator. The air conditioning cools the hot air inside the cabin, and in summer, the high humidity means the indoor air contains more water vapor. This water vapor is cooled, releases heat, and condenses into liquid water in the evaporator. The water is then collected by the air conditioning and discharged outside the car through the drain pipe.
