What Causes Fuel Injector Failure?

Fuel injector failure can be caused by the following reasons: 1. Poor fuel atomization: When the injection pressure is too low, the injector nozzle is worn or has carbon deposits, or the spring end face is worn or the spring force is reduced, the injector will open prematurely and close late, resulting in poor fuel atomization. 2. Damaged injector return line: When the needle valve pair is severely worn or the fit between the needle valve body and the injector housing is not tight enough, the injector's return fuel volume increases significantly, sometimes reaching 0.1–0.3 kg/h. If the return line is damaged or missing, the return fuel is wasted. 3. Enlarged needle valve nozzle: Due to continuous high-pressure fuel flow erosion, the needle valve nozzle gradually wears out, leading to decreased injection pressure, shorter injection distance, poor diesel atomization, and increased carbon deposits in the cylinder. 4. Needle valve seizure: Water or acidic substances in the diesel can cause the needle valve to rust and stick. If the needle valve sealing cone surface is damaged, combustible gas in the cylinder can also enter the mating surface, forming carbon deposits that cause the needle valve to seize, rendering the injector non-functional and stopping the cylinder. 5. Wear on the needle valve body end face: The needle valve body end face is subjected to frequent reciprocating impacts from the needle valve, which over time forms a concave pit, increasing the needle valve lift and affecting the injector's normal operation. 6. Air leakage and oil seepage at the injector and cylinder head joint: When installing the injector into the cylinder head, carefully remove carbon deposits from the installation hole. The copper gasket must be flat and should not be replaced with asbestos or other materials to prevent poor heat dissipation or sealing failure. 7. Wear on the needle valve and needle valve bore guide surface: The needle valve's frequent reciprocating motion inside the needle valve bore, combined with contamination from diesel impurities, gradually wears the guide surface, increasing the gap or causing scratches. This leads to increased internal leakage in the injector, reduced pressure, decreased fuel injection volume, delayed injection timing, and difficulty starting the diesel engine. 8. Injector dripping: During injector operation, the needle valve body's sealing cone surface is subjected to frequent strong impacts from the needle valve, along with continuous high-pressure fuel flow erosion. Over time, the cone surface develops scratches or spots, losing its sealing ability and causing the injector to drip fuel.

What to Do When Car Windshield Washer Fluid Freezes?

Manually clean the windshield, then start the vehicle and use the heat generated by the vehicle's operation to melt the washer fluid. Here is some relevant information about washer fluid: 1. Types of washer fluid: There are many types of washer fluid available in the domestic market, but they can mainly be divided into three categories: summer washer fluid, winter antifreeze washer fluid, and special antifreeze washer fluid. Summer washer fluid is primarily used to remove insect residue from the windshield. It is important to choose the appropriate washer fluid based on different climates and temperature conditions. 2. Functions of washer fluid: High-quality washer fluid features rapid snow and ice melting, anti-glare, and anti-fogging properties, which play a significant role in improving driving safety.

What to Do When the Car Fogs Up on Rainy Days?

Here are solutions to remove fog inside the car on rainy days: 1. Turn on the air conditioning cold air: Direct the air vents towards the windows, set the fan to maximum speed and the temperature to low to eliminate fog inside the car. 2. Open the windows at diagonal positions inside the car: This helps in removing fog. 3. Use anti-fog spray: Prevents water vapor from condensing into fog on the glass, one application can prevent fog for about ten days. Below are precautions for driving on rainy days: 1. Maintain a sufficient safe distance. 2. Use lights correctly. 3. Avoid slamming the brakes, stepping on the accelerator too hard, or turning the steering wheel abruptly.

Should CRV Use 92 or 95 Octane Gasoline?

Honda CRV uses 92 octane gasoline. Below is relevant information: 1. Gasoline Quality: Gasoline is produced and sold by octane rating, which is specified by national gasoline product standards and relates to different standards. For China (V), the ratings are 89, 92, 95 (with 98 included in the appendix). Gasoline grades are classified by octane number. 2. Reducing Fuel Consumption: The most cost-effective method to reduce fuel consumption is to increase the engine's compression ratio. Increasing the compression ratio involves altering the piston stroke—the more the air-fuel mixture is compressed, the greater the combustion reaction and the more complete the combustion.

What causes the JMC SVS light to come on and the diesel engine to lose power?

The SVS light in a car is similar to the engine malfunction light. When the SVS indicator lights up, it indicates that the engine control unit has detected an erroneous signal from a sensor or that it has exceeded the standard usage limits. Below is relevant information: 1. Possible faults that may cause the car's SVS light to come on include: Poor engine combustion state; engine knocking; poor fuel quality; unclean engine cylinder interiors with accumulated carbon deposits; the electronic control unit being unable to retrieve engine data. 2. Solutions for when the SVS light comes on: You can try starting the engine. If it fails to start, it could be due to an abnormal fuel pump that cannot supply fuel to the engine properly. If the engine still starts, it might be another sensor malfunction. In this case, the car may still be drivable, but the fault could potentially affect the vehicle's normal operation, such as increased fuel consumption or body shaking. It is recommended to have it checked at a repair shop as soon as possible.

How long does it take to transfer ownership of a new energy vehicle?

New energy vehicles follow the same transfer procedures as blue license plate vehicles, with similar processing times. However, it's important to note that new energy vehicle license plates can be transferred, but both the vehicle and plate must be transferred together. Separation of vehicle and plate is only permitted six months after the transfer. Details are as follows: 1. New Energy Vehicles: These utilize unconventional vehicle fuels as power sources (or conventional vehicle fuels with new onboard power devices), integrating advanced technologies in power control and driving systems to create vehicles with advanced technical principles, new technologies, and innovative structures. 2. New energy vehicles include four major types: Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEV, including solar-powered vehicles), Fuel Cell Electric Vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, or other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline, diesel, natural gas (NG), liquefied petroleum gas (LPG), ethanol gasoline (EG), methanol, and dimethyl ether.
