What engines are generally used in Changan Oushang?

Changan Oushang generally uses Dong'an engines, which are independently developed and produced by Changan Company, with the factory located in Chongqing. Different Changan Oushang models have different engines. The engine model for Oushang X5 is JL473ZQ2, with a maximum horsepower of 180, maximum power of 132kw, maximum power speed of 5500rpm, and maximum torque of 300N.m. The engine model for Oushang X7 is JL476ZQCF, with a maximum horsepower of 178, maximum power of 131kw, maximum power speed of 5500rpm, and maximum torque of 265N.m. For daily maintenance of Changan Oushang engines, 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 based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid faults, oil should be changed regularly based on usage conditions, and the oil quantity should be moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to pass through the bypass valve and bringing dirt back to the lubrication area, accelerating engine wear and internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and cylinder wall, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.

What are the body dimensions of the Volkswagen T-Roc?

The body dimensions of the Volkswagen T-Roc are 4318mm in length, 1819mm in width, and 1582mm in height. Below is some relevant information about the Volkswagen T-Roc: 1. Introduction to the Volkswagen T-Roc: The T-Roc is an SUV under FAW-Volkswagen, equipped with Alcantara seats, a panoramic sunroof, an electric tailgate, a BeatsAudio sound system, a 10.3-inch ActiveInfoDisplay full LCD instrument panel, among others. It also offers various active and passive safety features such as front collision warning. Additionally, the T-Roc has been optimized for space and handling performance. In terms of configuration, it includes a Panorama large panoramic sunroof, a BeatsAudio sound system, and other equipment. Safety-wise, the T-Roc uses up to 88% high-strength steel, and over 60 active and passive safety features enhance the vehicle's safety rating. 2. The "Short Overhang, Long Wheelbase" design of the Volkswagen T-Roc: With the longest wheelbase in its class at 2688mm/2680mm and a large net space, the T-Roc adopts an overall "Short Overhang, Long Wheelbase" design, achieving a large "net space" inside the cabin through the L99-2 measurement. L99-2 measures the distance from the front footwell to the center point of the rear seats, with the T-Roc's L99-2 value being 1789mm. Offering diverse space solutions, the T-Roc also features rich in-cabin storage space designs, a double-layer adjustable trunk space, and a 40:60 split-folding rear seat, among other space utilization schemes. Furthermore, the loading space can be effectively extended through roof racks or towing a caravan, providing users with more flexible and diverse space solutions.

How is the off-road performance of the Volvo XC90?

Volvo XC90 demonstrates commendable performance in off-road capabilities. Below are the details regarding the off-road performance of the Volvo XC90: 1. Theoretical passing performance of the Volvo XC90: When unloaded, the Volvo XC90 has a minimum ground clearance of 27.5cm, which indicates a lower likelihood of scraping the chassis. Additionally, the XC90 performs well in terms of approach angle, departure angle, and ramp breakover angle, reducing the probability of scratches when traversing rough or complex terrains. 2. Locking speed and extrication capability of the Volvo XC90: The XC90 is equipped with the fifth-generation Haldex all-wheel-drive system, featuring a multi-plate clutch central differential and open differentials on both the front and rear axles. During the all-wheel-drive extrication tests, the XC90 quickly passed three relatively simple scenarios: both rear wheels with traction, both front wheels with traction, and the cross-axle situation. However, in the more challenging single-wheel extrication tests (single front wheel with traction and single rear wheel with traction), the all-wheel-drive system responded slightly slower. Specifically, it took 7 seconds to pass the test with only the single front wheel having traction. Overall, the locking and response capabilities of the all-wheel-drive system are quite good.

Are Sports Cars Manual or Automatic?

Sports cars are automatic. Here is a partial introduction about sports cars: 1. Automatic transmission shifting: The shifting speed is faster. Most sports cars use dual-clutch transmissions, which are very suitable for performance cars and sports cars. A dual-clutch transmission is a product developed based on manual transmissions. 2. Dual-clutch transmission: This type has fast shifting speed and relatively high transmission efficiency. There are two types, one is dry and the other is wet. The clutch plates of a dry dual-clutch transmission are not immersed in transmission oil.

Why Do Vehicles Need to Use Urea?

Vehicles need to use urea to reduce harmful nitrogen oxides in the exhaust into nitrogen and water. Here is some information about why vehicles use urea: 1. Reason Analysis: The exhaust directly emitted by the engine can no longer meet regulatory requirements, leading to the development of exhaust aftertreatment devices. The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter, which can be reduced inside the engine through technical means. 2. Principle: The exhaust primarily contains nitrogen oxides. Urea is injected into the exhaust aftertreatment device, where it decomposes into ammonia at high temperatures. Under the action of a catalyst, the ammonia reacts with nitrogen oxides to produce harmless nitrogen and water. This device is called the SCR (Selective Catalytic Reduction) aftertreatment system.
