Where is the Yellow River Truck produced?

Yellow River Truck is produced in Jinan. Product Origin: It is widely known that the Yellow River brand heavy-duty trucks are manufactured in Jinan. However, there are different opinions about when the first Yellow River brand truck was produced. According to some records: In April 1960, Jinan Automobile Manufacturing Plant trial-produced China's first heavy-duty truck—the Yellow River brand 8-ton truck, ending the history of China's inability to produce heavy-duty vehicles. Development History: In the late 1960s, the Yellow River JN150 model began to enter the international market. After the reform and opening-up, Jinan Automobile Manufacturing Plant developed into China National Heavy Duty Truck Group (Sinotruk), which once neglected the development of the Yellow River brand trucks, focusing instead on the introduced Steyr series, leading to difficulties in the company's development. In 2001, Sinotruk was transferred to the management of Jinan City. Since 2003, Sinotruk has cooperated with foreign partners to jointly design and develop a new series of mid-to-high-end medium and heavy-duty trucks, including the 'Yellow River Prince', 'Yellow River Young Marshal', and 'Yellow River General' series.

Has the 2021 Toyota Hybrid Engine Oil Emulsification Issue Been Resolved?

Toyota hybrid engine oil emulsification issue has not been resolved yet. Hazards of engine oil emulsification: Oil and water are immiscible, but under certain temperatures and specific conditions, they can mix and cause emulsification. Emulsified oil appears white in color. Since engine oil lubricates engine components, its performance significantly deteriorates after emulsification, leading to severe engine wear and reduced engine lifespan. Therefore, engine oil emulsification is not a minor issue. Normal engine oil emulsification phenomenon: Sometimes, when the engine is turned off and cools down, air enters the valve chamber where the camshaft is located. The condensation of water vapor in the air can cause slight emulsification on the oil cap. The accumulation of emulsion on the oil filler cap is entirely different from the engine oil emulsification issue. This is a normal occurrence and does not fall under the category of engine oil emulsification problems.

Methods for Defogging the Car Interior on Rainy Days

When driving on rainy days, it is common for the car interior to fog up, which can obstruct the driver's view and reduce driving safety. Here are some methods to remove fog from the car interior on rainy days: 1. If the temperature difference between the inside and outside of the car is small and the fog is minimal, simply prepare a highly absorbent towel and gently wipe the interior glass. 2. If fog reappears after wiping, slightly lower the window to create a small gap, reducing the temperature difference between the inside and outside of the car, which will cause the fog to disappear. This method is not suitable for snowy or rainy weather or when driving on highways. 3. You can quickly remove fog from the car interior by turning on the air conditioning. After activating the hot/cold air, use the recirculation mode and adjust the air vents to blow onto the glass, and the fog will clear immediately. 4. Spray a defogging agent onto the inner surface of the car glass and wipe it clean. This not only removes dirt from the glass but also forms a protective film that prevents moisture from condensing into fog on the glass. One application can prevent fogging for about ten days.

What is the battery model of the Buick Excelle?

The battery model of the Buick Excelle is 12V55AH. Car batteries typically have a voltage of 12V or 24V. Generally, gasoline-powered passenger cars for household use have 12V batteries, while diesel engines, which operate differently from gasoline engines, require higher voltage and thus often use 24V batteries. The Buick Excelle has a body length, width, and height of 4468mm, 1765mm, and 1469mm respectively, with a wheelbase of 2611mm. The tire model for the Buick Excelle is 185/65R15. This tire has a relatively high aspect ratio, which enhances its ability to absorb bumps and vibrations, making it well-suited for family use. Car battery replacement considerations: The warranty period for car batteries is typically around 2 years. First, measure the battery using a high-frequency discharger or battery tester. Under a load current of no less than 110 amps, the minimum voltage should not drop below 9.6 volts and must remain stable for 5 seconds. If the voltage is below 9.6 volts but remains stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly.

How to close the sunshade of the Hongqi HS5 sunroof?

The sunroof opening and closing function is located below the SOS button. Features of the Hongqi HS5: The new Hongqi HS5 is full of charms and highlights, briefly summarized as mH5, where m stands for numerous, H represents charms and highlights, and the 5th power signifies five major characteristics: supreme luxury, supreme elegance, supreme comfort, supreme intelligence, and supreme safety at its core. Powertrain of the Hongqi HS5: The Hongqi HS5 is equipped with a low-power version of the CA4GC inline four-cylinder turbocharged direct injection engine, with a rated power of 165kW and a maximum torque of 340N·m. This engine is independently developed by the FAW Group, incorporating ten industry-leading technologies such as high-compression ratio Miller cycle combustion technology, 350bar precise fuel injection technology, full MAP intelligent thermal management technology, and all-aluminum lightweight engine technology, achieving a thermal efficiency of 39%. The CA4GC aluminum-steel engine is lightweight, approximately 50% lighter than cast iron cylinder blocks of the same displacement. Additionally, thanks to the platform mesh grinding process, the engine reduces wear on the cylinder liners and piston rings, extending the overall engine lifespan.

Is a U-turn allowed where left turns are prohibited?

At intersections where left turns are prohibited, U-turns are also not allowed. If a U-turn is made in a no-U-turn zone, according to the "Road Traffic Safety Law," the violator will be fined 200 yuan and receive 3 penalty points. Generally, on long roads, solid lines, dashed lines, or no-U-turn signs are present in the middle sections or before intersections. If the line is a yellow dashed line or white dashed line without any prohibition signs, a U-turn is allowed. However, U-turns are prohibited if there are solid lines or prohibition signs. Scenarios where U-turns are permitted: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn is allowed. If there is a U-turn traffic light, follow its instructions. In the absence of a traffic light, make the U-turn based on the situation without obstructing other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: If there are no explicit signs prohibiting U-turns, they are allowed. "No explicit prohibition" means the absence of signs like "No U-turn," "No Left Turn," or solid central lines. In such cases, U-turns can be made confidently. Yellow grid zones: Yellow grid lines are no-stopping zones, typically marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Stopping (including waiting at traffic lights) on these grids is a violation. Although stopping is prohibited, U-turns are allowed in yellow grid zones unless a central barrier is present. These zones effectively permit U-turns. Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, proceed only when it is green. When "No Left Turn" and "U-turn Permitted" signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" and "No Left Turn" are not the same. Precautions when making U-turns at intersections: Observe road markings. If solid lines are present, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If a "No Left Turn" sign is displayed, U-turns are also prohibited at that intersection, even if no explicit "No U-turn" sign exists, as U-turns inherently involve left-turning movements. U-turns must be made from the innermost left-turn lane. If in the second left-turn lane, U-turns are not permitted at that intersection. Yield to oncoming traffic when making a U-turn. Proceed only if it does not interfere with straight-moving vehicles; otherwise, you bear full liability for any accidents. Near stop lines at intersections, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—some may have straight arrows. Even without explicit no-U-turn signs, U-turns are prohibited in such lanes. U-turns must not be made on pedestrian crosswalks, as this is also a violation.
