What Causes Drowsiness While Driving?

Does exceeding the upper limit of the engine oil dipstick have any impact?

Exceeding the upper limit of the engine oil dipstick does have an impact, and the effects include: 1. Hindering the operation of the crankshaft; 2. Increasing engine pressure, which affects the engine's power output. The functions of engine oil are: assisting in engine lubrication and reducing friction, cooling and temperature reduction, sealing and leak prevention, rust and corrosion prevention, and shock absorption. The method for changing engine oil is: 1. Run the engine to bring it to operating temperature; 2. Engage the handbrake and lift the vehicle; 3. Unscrew the filter and drain the oil; 4. Apply new oil to the gasket of the new filter; 5. Pour the new oil into the oil pan; 6. Check for leaks under the engine; 7. Lower the vehicle, check the oil dipstick, and start the engine; 8. Turn off the engine and repeat the oil level check.

Can You Press the Clutch to Shift While Stepping on the Accelerator?

You can press the clutch to shift while stepping on the accelerator. Specific details are as follows: 1. Hazards: Shifting without fully depressing the clutch can easily damage the clutch. The key to starting a manual transmission car lies in the coordination between the accelerator and the clutch. 2. Additional Information: The clutch refers to the separation device between the car engine and the transmission, also known as the clutch. In automatic transmission cars, the clutch is integrated into the transmission to achieve automatic shifting. The reason for separating the power from the wheels is that the engine needs to change speeds at different vehicle speeds. The driving and driven parts of the clutch rely on friction between contact surfaces, or use liquid as a transmission medium (hydraulic coupling), or magnetic transmission (electromagnetic clutch) to transmit torque, allowing temporary separation and gradual engagement, while permitting relative rotation between the two parts during transmission.

What tire model is used for the Dongfeng Peugeot 408?

Dongfeng Peugeot 408 uses the tire model 215/50R17, and it is equipped with Goodyear tires. The Goodyear Tire & Rubber Company was founded in 1898 and has a history of over a century. Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company primarily produces tires, engineered rubber products, and chemical products in more than 90 factories across 28 countries. Today, Goodyear employs over 80,000 people worldwide. For the tires of the Dongfeng Peugeot 408 in daily use, the following points should be noted: Regularly inspect the tire surface for cracks, deformations, or other defects. Due to driving wear, the tread grooves of the tires gradually become shallower. If the tread wears flat, it will lose its drainage and anti-skid functions, significantly reducing the car's performance. Small cracks may seem minor but can pose a risk of tire blowouts at high speeds. Additionally, promptly remove small stones lodged in the grooves. Try to park on flat ground. Avoid parking on roads with thick, sharp, or pointed stones. Do not park the car near or in contact with petroleum products, acids, or other materials that may deteriorate rubber. After parking, the driver should not turn the steering wheel, as this action accelerates tire wear. Do not splash water to cool down. In hot weather or during high-speed driving, tires are prone to overheating, and tire pressure may increase. In such cases, park to allow the tires to cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this may cause abnormal aging of the tread rubber. Avoid sudden braking. Try to minimize frequent or emergency braking to prevent accelerated tread wear caused by dragging between the tires and the road.

What are the effects of driving with the handbrake engaged?

Driving with the handbrake engaged for an extended period can lead to accelerated wear, overheating and hardening of the brake pads, and elongation of the handbrake cable. This results in reduced braking performance, and the burnt smell sometimes noticed by drivers originates from this issue. In severe cases, smoke may even emerge from the rear of the vehicle. Prolonged driving with the handbrake engaged can also cause the brake caliper to seize, brake fluid leakage, and excessive temperature of the brake fluid, leading to a complete loss of braking function. Below are some precautions for handbrake usage: 1. Always engage the handbrake when parking and turning off the engine. There have been cases where drivers forgot to engage the handbrake after parking, leading to the vehicle moving on its own and causing accidents, especially on slopes. Ensure the vehicle is in gear, the handbrake is engaged, and wait for the vehicle to stabilize before exiting. 2. The handbrake is often used in conjunction with neutral gear. Even during brief stops at traffic lights, remember to engage the handbrake when in neutral. This not only prevents the vehicle from rolling on uneven roads but also allows your right foot to rest briefly from the brake pedal. Use stationary objects nearby as a reference to check for any rolling. 3. Avoid pulling the handbrake too tightly. Many modern vehicles have spring-loaded handbrakes with multiple notches. The higher the handbrake is engaged, the more tension is placed on the spring. Engage it just enough to prevent the vehicle from moving (about 70-80% of full engagement) to prolong the handbrake's lifespan. 4. Before moving off, ensure the handbrake is fully disengaged. Press the release button and lower it completely. Many beginners forget to disengage the handbrake, which can cause damage. Most vehicles now have warning sounds to alert drivers if the handbrake is still engaged, so pay attention to the dashboard alerts. 5. In case of brake system failure on the highway, you can intermittently and gradually apply and release the handbrake to bring the vehicle to a stop.

Where is the Dongan Mitsubishi Engine Produced?

Dongan Mitsubishi engines are produced by Harbin Dongan Engine (Group) Co., Ltd. in Heilongjiang, China, and are classified as domestically manufactured engines. Models such as the Changan Star 9, Dongfeng Fengxing, and Yongyuan A380 utilize Dongan Mitsubishi engines. Specifically, the Changan Star 9 is equipped with the 4G15S engine model, which delivers a maximum power output of 85kW, a maximum torque of 150 Nm, and a maximum horsepower of 116. For the daily maintenance of the Changan CS15's engine, the following methods are recommended: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD to SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB to CD grade diesel engine oil according to mechanical load, ensuring the selected standard meets or exceeds the manufacturer's requirements. Regularly replace the engine oil and oil filter. The quality of any lubricating oil deteriorates over time with use. After a certain mileage, its performance degrades, potentially causing various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or activate the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication points, 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. These substances mix with metal particles from component wear, forming sludge. In small amounts, the sludge remains suspended in the oil, but in larger quantities, it precipitates, clogging filters and oil passages, making engine lubrication difficult and leading to wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates smoothly but also extends the overall lifespan of both the radiator and the engine.

What does it mean when the car transmission warning light comes on?

The reasons for the car transmission warning light coming on are: 1. Transmission computer or electronic component failure; 2. Transmission oil contains impurities or is severely insufficient; 3. Damage to internal transmission components; 4. False or incorrect warning light indication. Methods for maintaining a car transmission include: 1. Regularly changing the transmission oil; 2. Frequently checking the oil level; 3. Avoiding coasting in neutral; 4. Skipping gears when upshifting; 5. Not forcing the transmission into neutral; 6. Minimizing idle warm-up time; 7. Avoiding gear grinding when shifting; 8. Cleaning the transmission. The functions of a transmission are: 1. Changing the gear ratio to expand the range of torque and speed variation for the driving wheels; 2. Enabling the car to reverse while the engine's rotation direction remains unchanged; 3. Using neutral to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output.
