What to Do When the Car Engine Light Comes On?

If the car engine light comes on, it may indicate a fault in the engine. You should park the car in a safe location for inspection, which generally requires professional personnel to check and handle. Only after the inspection and necessary repairs should you start the car and drive again. Below are the possible reasons why the engine light comes on: 1. It could be an oxygen sensor malfunction. The oxygen sensor measures the amount of oxygen in the exhaust gas after combustion, and its failure can lead to a sharp increase in fuel consumption. 2. It might be a problem with the catalytic converter. The catalytic converter rarely fails, but the possibility of it being damaged cannot be ruled out. 3. If the fuel tank cap is not properly closed or is missing, this can also cause the engine fault light to come on. 4. A faulty thermostat can also trigger the engine fault light, as it is responsible for maintaining a constant temperature of the engine coolant. 5. Aging ignition coils can cause the engine fault light to illuminate. Issues like spark plug failure or excessive engine compartment temperature can lead to ignition coil failure. 6. A malfunctioning air flow sensor can also cause the engine fault light to come on, along with increased fuel consumption.

What does a 6-speed dual-clutch transmission mean?

6-speed dual-clutch transmission means there are two gearboxes, one controlling gears 1, 3, 5 and the other controlling gears 2, 4, 6. While using the current gear, the next gear is already automatically prepared, so the shifting time is very short without the delay of manual transmissions. Below is an introduction to the 6-speed dual-clutch transmission: 1. The 6-speed dual-clutch transmission is based on manual transmission but belongs to automatic transmission. It not only has the flexibility of manual transmission and the comfort of automatic transmission, but also provides uninterrupted power output, making it much better than ordinary manual and automatic transmissions. 2. Since the 6-speed dual-clutch transmission has two clutches that cooperate to switch gears, there is always power output during the shifting process without stagnation. Therefore, this technology is widely used, especially in sports cars where it is most widely applied. Uninterrupted power output makes the car's power more sufficient, and shifting is also more convenient. 3. The dual-clutch transmission was invented by the Frenchman Adolphe-Kégresse before World War II and was planned to be equipped in the Citroën Traction, but the market conditions at that time were not suitable for commercial applications. The dual-clutch transmission had to wait half a century before it began to be equipped in civilian vehicles.

Why does the car keep drifting while driving?

The main reasons for a car drifting are excessive tension causing overly large steering wheel movements or a steering wheel that's too tight to return to center. Below are techniques for maintaining straight-line driving: 1. First, hold the steering wheel steady and straight. The car may slightly deviate from a straight line; if it drifts to one side, gently turn the steering wheel slightly in the opposite direction. 2. Find suitable reference points on the road to help maintain straight-line driving over time. Examples include the center line of the road, roadside lines, curbs, and roadside trees. 3. Looking far ahead makes it easier to drive straight. Beginners often drift when driving on wide road sections because the vast space and broad field of vision can weaken the reference points from roadside and markings. New drivers should focus their gaze far ahead to better judge if they're drifting.

Do I Need to Check Traffic Lights When Making a U-Turn?

Whether you need to check traffic lights when making a U-turn depends on the specific situation. Sometimes you need to observe the traffic lights, while other times you can make a U-turn without checking them. Here are some important considerations for vehicle U-turns: 1. U-turns are not allowed at locations with 'No U-turn' or 'No Left Turn' signs. 2. Intersections without U-turn signals but with left-turn signals allow U-turns. Drivers can use the left-turn lane to make a U-turn at the central median or when approaching the intersection, provided it does not interfere with normal traffic flow. 3. U-turns are permitted in yellow grid areas. While parking is prohibited in these areas, if the traffic light ahead is red, vehicles behind should avoid stopping in this zone and can complete the U-turn at the central guardrail. 4. U-turns are prohibited in zebra crossing areas. Drivers cannot make U-turns on pedestrian crosswalks but can do so after crossing the zebra crossing when the light is green. 5. Intersections with U-turn indicators allow U-turns. At intersections with U-turn traffic lights or road signs indicating U-turns, drivers can make a U-turn after ensuring safety.

Where is the RPM Sensor Located?

The engine RPM sensor is installed on the rear crankshaft oil seal, with a small hole on the side of the cylinder block. Below is a detailed introduction to the RPM sensor: 1. The engine RPM sensor is an inductive sensor that captures the engine speed and the precise angular position of the crankshaft for input into the system. A separate signal wheel for the engine RPM sensor is mounted on the flywheel; 2. The signal wheel is designed as a wheel with multiple tooth segments, divided into a total of 60 segments. Each time the signal wheel passes the sensor, an alternating voltage is generated, the frequency of which varies with the speed. The frequency indicates the level of RPM; 3. To identify the crankshaft position, there is a gap between two tooth segments on the signal wheel. The engine RPM sensor is used to identify the engine speed. Together with the Hall sensor, it identifies the top dead center of the first cylinder's ignition, thereby determining the fuel injection timing and ignition timing.

How to Adjust the Clutch of Baojun 510?

Baojun 510 clutch adjustment method: Fine-tuning can be done by adjusting the clutch control part, but if it is a hydraulic clutch control part, it cannot be adjusted. Here are the usage methods for the Baojun 510 clutch: 1. The Baojun 510 is equipped with a manual transmission; when depressing the clutch, follow the principle of 'one fast, two slow, three linkage.' 2. When lifting the clutch pedal, adhere to the operation principle of 'one fast, two slow, three linkage.' 3. When starting, depress the clutch pedal swiftly and completely to ensure the clutch is fully disengaged. 4. Once you feel the clutch pressure plate gradually engaging to the semi-linked state, slow down the lifting speed of the pedal. During the process from semi-linkage to full engagement, lift the clutch pedal slowly. 5. While lifting the clutch pedal, gradually press the accelerator pedal according to the engine's power to ensure a smooth start. The throttle operation should be steady and appropriate; only when the clutch is fully engaged can you increase the throttle.
