How to Remove the Key If It Won't Come Out?

Turn the key counterclockwise two notches, then gently press it in and turn it one more notch to remove the key. Alternatively, press the key in directly and turn it counterclockwise three notches to pull it out. Below are explanations for why the key might not come out: 1. After turning off the engine, the key getting stuck is common in automatic transmission models. The reason is that the gearshift is not fully returned to the P (Park) position. It may appear to be in place, but it hasn't actually triggered the electronic sensor, or there might be obstacles like coins in the gear slot preventing it from returning. In this case, the owner should check the gear slot for any obstructions, remove them, start the car, shift the gear again to ensure it's fully engaged, and the key can then be removed. 2. After turning off the engine, the most common reason the key won't come out is the steering wheel lock engaging, which prevents key removal. In this situation, avoid forcing the key. Instead, slightly move the steering wheel while turning the key to release it. Some vehicles are designed with enhanced security features that prevent key removal unless the gearshift is in the P (Park) position. Therefore, to remove the key, the gear must be set to P.

What engine is used in the Dongfeng AX7?

The engine of the Dongfeng Fengshen AX7 is from the French PSA Group. The engine model of the Dongfeng Fengshen AX7 is DFMC15TP1, with a maximum power of 140 kW, maximum torque of 300 Nm, maximum horsepower of 190 Ps, maximum power speed of 5200 rpm, and maximum torque speed range of 2000-4000 rpm. For daily maintenance of the Dongfeng Fengshen AX7 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

How to Shift from D Gear to S Gear?

While the car is in motion, you can directly shift from D gear to S gear. The D gear can also be engaged into S gear during acceleration. Here is an introduction to shifting from D gear to S gear in an automatic transmission car: 1. When shifting from D gear to S gear in an automatic transmission car, there is no need to press the brake or come to a complete stop. The car can directly shift from D gear to S gear while driving, and the D gear can also be engaged into S gear during acceleration. After shifting to S gear, the power output becomes more intense, and fuel consumption increases accordingly, with power and fuel consumption being directly proportional. 2. For normal driving, D gear is generally used, as it has a very wide range of applications. In situations requiring higher power, S gear or sport mode can be used.

What is the difference between SOHC and DOHC engines?

SOHC engine refers to its intake system using a single overhead camshaft, which means one intake valve and one exhaust valve; DOHC engine refers to its intake system using double overhead camshafts, generally with multiple valves per cylinder, commonly 4 valves. DOHC has two overhead camshafts placed on the cylinder block, the first one drives the intake valves, and the second drives the exhaust valves; SOHC, a single overhead camshaft in the cylinder head uses one camshaft to directly drive the intake and exhaust valves, featuring a simple structure and is suitable for high-speed engines. The single camshaft has a simpler mechanical structure, fewer issues, and greater low-speed torque. The opening times of the intake and exhaust valves in a single camshaft are fixed, but its mechanical simplicity, ease of maintenance, and fuel efficiency are all advantages of SOHC. The double camshaft can adjust the valve overlap angle, thus delivering greater horsepower, but it lacks low-speed torque and, due to its more complex mechanical structure, has higher manufacturing costs and maintenance expenses. The double camshaft technology originates from racing, primarily to control the timing difference between the intake and exhaust valves. Neither is inherently better; single and double camshafts are just structurally different.

Do You Still Need to Press the Brake Pedal to Shift Gears While Driving an Automatic Transmission Car?

For automatic transmission vehicles, you need to press the brake pedal and also press a switch on the gear lever when shifting into P (Park) or R (Reverse) gears. Other gears can be engaged directly without pressing the brake. Additional information is as follows: 1. The requirement to press the brake for shifting is to prevent driver misoperation. Park and Reverse are two critical gears in the transmission system. Mistakes during shifting could cause the vehicle to lurch forward or backward, so for safety reasons, it's mandated that the driver must press the brake. 2. When pressing the brake, avoid pressing too lightly. Otherwise, the brake pedal sensor may not detect that the driver has pressed the brake, and the gear will not be released. Additionally, the vehicle may not achieve optimal braking performance.

The Meaning of 175/70R14

175 indicates the tire width, which is 175 millimeters; 70 is called the aspect ratio, meaning the ratio of the tire's sidewall height to its width is 70%; R is the international code for radial tires, representing "radial tire"; 14 refers to the diameter of the wheel rim, which is 14 inches. Here is some information about tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; 2. Transmit traction and braking torque, ensuring good adhesion between the wheel and the road surface to improve the car's power, braking, and passability; work together with the car suspension to mitigate impacts during driving and dampen the resulting vibrations; 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency.
