What is the purpose of adding urea to a vehicle?

The purpose of adding urea to a vehicle: It is mainly used to treat exhaust gases and reduce pollutants in the emissions. Below is an extended explanation about adding urea to vehicles: 1. Only vehicles equipped with diesel engines require the addition of urea. Most vehicles that use diesel engines include buses, trucks, semi-trailers, and heavy-duty trucks, among others. 2. The working principle of a diesel engine differs from that of a gasoline engine. Diesel engines do not have spark plugs, so after the compression stroke ends, they do not rely on spark plugs to ignite the combustible mixture but instead rely on compression ignition. 3. After the compression stroke ends, the pressure and temperature of the combustible mixture are relatively high, allowing the mixture in diesel engines to self-ignite. Additionally, most diesel engines are equipped with turbocharging technology, providing relatively strong power, which necessitates the use of urea to treat the exhaust gases.

What is the wheelbase of the Audi Q8?

The wheelbase of the Audi Q8 is 2995 mm. The length, width, and height of this car are 4986 mm, 1995 mm, and 1702 mm respectively. Here is more information about the Audi Q8: 1. Engine: The Audi Q8 is equipped with two engines, one is a 2.0-liter turbocharged engine, and the other is a 3.0-liter turbocharged engine. The engines are paired with an 8AT transmission. 2. Model: The Audi Q8 is a mid-to-large-sized SUV that emphasizes comfort. 3. Suspension: The front suspension of the Audi Q8 uses a multi-link independent suspension, and the rear suspension also uses a multi-link independent suspension. The multi-link independent suspension can improve the wheel's ground contact performance, enhance the wheel's grip, and thus improve the car's handling.

Use Parking Lights or Low Beams at Night?

Use low beams at night. Parking lights are lamps installed at the higher positions of the front and rear of the vehicle, similar to the anti-collision lights on the wingtips of aircraft. They are primarily used during dusk, overcast days, or rainy/foggy conditions to indicate the vehicle's width and height, helping drivers judge relative positions and vehicle sizes during encounters or overtaking. Typically, parking lights are white at the front and red at the rear. Low beams have an illumination range of about 30 to 40 meters, designed for close-range lighting with a wide coverage area, short projection distance, and non-adjustable focus.

Where is the Renault Air Filter Located?

Renault Koleos air filter is located inside the glove compartment on the passenger side. To replace it, first open the plastic buckle on the right side of the glove box, then squeeze both sides of the glove box to remove it, and finally pull out the old air filter and replace it with a new one. Renault air filter replacement method: 1. Japanese cars usually install the air filter behind the glove compartment on the passenger side. To replace the air filter, first open the glove box cover. 2. Locate the fixed buckle on the right side of the glove box and pull it outward with force. 3. Remove the fixed buckle of the glove box cover to detach it. 4. Squeeze both sides of the glove box towards the middle with both hands, and the glove box can be removed. 5. After removing the glove box, you can see the air filter cover. Press the fixed buckles on both sides of the cover with force, and the cover can be removed. 6. Pull out the old air filter to the outside. 7. Install the new air filter and restore it to its original position in the reverse order of the disassembly process.

What kind of oil is valve body oil?

Valve body oil is transmission oil, which is a lubricant used to keep the gear shift system clean. It serves to lubricate and prolong the lifespan of the transmission components, providing effective lubrication even at low temperatures and reducing oil loss under harsh operating conditions. Depending on the structure of the transmission, transmission oil is further divided into automatic transmission fluid (ATF) and manual transmission oil. Automatic transmission fluid is specifically designed for automatic transmissions, whereas early automatic transmissions did not have dedicated fluid and instead used engine oil. Manual transmission oil, commonly referred to as gear oil, is used for lubricating hypoid gear drive shafts and manual transmissions that operate under severe conditions with high impact loads.

What engine does the Jetta use?

The Jetta is equipped with 1.4L and 1.5L naturally aspirated engines, manufactured by FAW-Volkswagen Engine (Chengdu) Co., Ltd. The Jetta's engine model is EA211. The 1.4L engine has a maximum power output of 66 kW and a maximum torque of 132 N·m, while the 1.5L engine delivers a maximum power of 81 kW and a maximum torque of 150 N·m. For daily maintenance of the Jetta's engine, the following methods can be employed: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will deteriorate during use. After a certain mileage, performance degradation can cause various engine problems. To prevent 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 becomes clogged and oil cannot pass through, the filter element may rupture or the safety valve may open, allowing oil to bypass through the relief 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, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil, but in large quantities, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of both the radiator and the engine.
