When the SVS light comes on in a Jiangling diesel vehicle accompanied by insufficient power, this is a common issue in my repair experience, often related to fuel system faults. For example, a clogged diesel filter can lead to poor fuel supply due to accumulated impurities, causing the engine to lack sufficient fuel—like running on an empty stomach. Alternatively, a failing high-pressure fuel pump may result in inadequate fuel pressure and incomplete fuel injection. Sometimes, air or water entering the fuel lines can also trigger similar issues, making the vehicle sluggish. It's advisable to first check the filter's condition and replace it if dirty. If the light persists, it's best to visit a professional repair shop to scan for fault codes, as it might be an electronic signal misjudgment. Using standard diesel fuel regularly can help reduce such occurrences.

How Many Lights Should Be Turned On When Driving in Heavy Fog?

When driving in heavy fog, 3 types of lights should be turned on. Specific lights to activate: In foggy conditions, drivers should turn on fog lights, hazard warning flashers, and low beam headlights. Additionally, during fog, rain, or snow, it's also necessary to activate low beam headlights along with clearance lights and rear position lights. Light activation levels: When the fog is extremely dense with very low visibility, hazard warning flashers must be activated. This helps alert oncoming vehicles ahead. However, drivers should exercise caution when using these lights during turns or lane changes, as the turn signals become ineffective when hazard lights are on, which could potentially lead to accidents. For moderate fog conditions with relatively better visibility, front fog lights and low beam headlights should be used. Sometimes, when driving at higher speeds, rear fog lights should also be activated. In light fog conditions with higher visibility, simply turning on clearance lights and rear position lights together is sufficient.

Why doesn't an automatic transmission car move when shifted to R gear without pressing the accelerator?

An automatic transmission car not moving when the accelerator is pressed may be due to the clutch not fully engaging; the handbrake not being released; the gear being stuck and not fully engaged; or wear and tear on the clutch disc. Automatic transmission gear positions: Generally, an automatic transmission has 6 to 7 gear positions, arranged in order from front to back. They are P (Park), R (Reverse), N (Neutral), D (Drive), and some Drive positions include D, 3, 2, and 1 gears. Some models have only three Drive positions (D, 2, 1). If equipped with a four-speed transmission, there may also be an overdrive selection switch (O/D) to engage the overdrive gear. Correct driving method for automatic transmission cars: Start the engine with the gear shift lever in the P position, and you must press the brake pedal to shift from P to other gear positions. When starting, push the gear shift lever to a lower gear position (i.e., 2 or 1, some may also have 3), and after the speed increases to a certain level, shift to D for normal driving. If cruising at high speed on a highway, you can use the O/D gear to save fuel.

Which is Quieter: Three-Groove or Four-Groove Tires?

Theoretically, four-groove tires offer better noise reduction compared to three-groove tires, but noise reduction primarily depends on the tire's compound and carcass structure. Introduction to Tires: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. They are typically installed on metal rims to support the vehicle body, absorb external shocks, maintain contact with the road surface, and ensure driving performance. Performance Requirements for Tires: Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during use. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. Additionally, they require excellent wear resistance, flexibility, and low rolling resistance with minimal heat generation.

How to Maintain a Car Dashboard?

Car dashboard maintenance methods are: 1. Regularly use a specially diluted cleaning agent to wipe, avoiding high concentration that may cause plastic parts to lose gloss or turn white; 2. Evenly spray the prepared cleaning agent on the surface of the dashboard, then use both a dry and a wet towel to wipe twice, first with the wet towel followed by the dry one; 3. Apply a layer of cleaning protective wax to extend its service life. The dashboard, also known as the instrument panel, is widely used in the cabins of all vehicles and engineering machinery. It mainly consists of instruments, steering wheel, dashboard shell, dashboard frame, and dashboard wiring harness.

What is the Impact of a Charcoal Canister on Fuel Consumption?

Charcoal canisters can affect fuel consumption levels, and a damaged charcoal canister can lead to increased fuel consumption. Working process of the charcoal canister: Due to the adsorption properties of activated carbon, when the vehicle is running or turned off, gasoline vapors from the fuel tank enter the upper part of the charcoal canister through the pipeline, while fresh air enters the lower part of the charcoal canister. When the vehicle is in motion, the charcoal canister solenoid valve opens at the appropriate time to reintroduce the absorbed fuel vapors into the intake manifold, which saves fuel and is more environmentally friendly. Symptoms of a damaged charcoal canister: If the charcoal canister is damaged, a gasoline odor may be detected inside or around the vehicle. If the air inlet of the charcoal canister or its filter becomes clogged, it can cause fluctuations in the engine idle speed. If the charcoal canister solenoid valve remains open continuously, an overly rich air-fuel mixture can make the engine difficult to start or even cause it to stall when starting.

Why Do Others Start So Fast with a Manual Transmission?

Manual transmission cars start quickly mainly due to proper clutch and throttle control. As long as the clutch and throttle are skillfully managed, manual transmission vehicles can achieve faster starts. Below is a detailed introduction to starting with a manual transmission: Correct Operation for Manual Transmission Start: For starting a manual transmission car, many beginners fear stalling. The correct sequence of operations should be to quickly depress the clutch, shift into first gear, release the handbrake, then slowly release the clutch. When you feel the vehicle begin to move forward, hold the clutch steady, lightly press the accelerator, and gradually release the clutch. Precautions for Manual Transmission Start: When starting, if you feel the engine lacks power and is about to stall, immediately press the clutch pedal again and restart. The clutch pedal must be operated according to the correct technique. Releasing it too slowly can accelerate wear on the friction surfaces of the clutch disc, pressure plate, and flywheel, leading to clutch component damage. Releasing the clutch pedal too quickly or pressing the accelerator too lightly can cause the engine to stall.
