How Many Models Does Changan Nanjing Engine Have?

There are two models: one is the 1.5-liter turbocharged engine used in the CS75 and CS75 PLUS, and the other is the second-generation Blue Core engine. Below are the characteristics of the Blue Core engine: 1. Advantages: The high-pressure direct injection technology is industry-leading. Most engines can only achieve up to two fuel injections, but this engine can achieve up to five fuel injections within a single stroke, making it the highest injection frequency among mass-produced engines worldwide. It features precise and efficient scavenging, full working condition closed-loop control for fuel injection, improving low-end torque by over 20%, and reducing the maximum torque speed to 1450 rpm. 2. Disadvantages: When the engine operates in the high RPM range, the infotainment system responds slowly, the air conditioning control area lacks full functionality, and the tire noise is very loud at high speeds. Combined with the noise from the hybrid engine, the driving environment is suboptimal. Additionally, during acceleration, the transmission downshifts slowly with significant lag.

What Are the Causes of Overheating in Motorcycle Engines?

Motorcycle engine overheating can be caused by factors such as improper break-in for new or overhauled vehicles and incorrect maintenance and assembly processes. Here are the specific details: 1. Neglecting the break-in period for new or overhauled motorcycles: New motorcycles or those that have undergone major repairs have rougher component surfaces, certain deviations in part geometry and assembly positions, and smaller contact areas in friction pairs. This results in higher pressure per unit contact area, accelerated wear, and increased heat generation from friction. 2. Improper maintenance and assembly techniques: Severe wear on the big-end bearing of the engine crankshaft or improper installation of left and right crankshaft bearings can cause the vertical centerline of the crankshaft assembly to deviate from the cylinder block center after installation. This misalignment leads to lateral tilting of the connecting rod and piston wobble within the cylinder, causing uneven wear on piston rings and cylinder walls, reduced cylinder pressure, and ultimately engine overheating. In four-stroke engines, significant wear on the camshaft lobes or insufficient cam height reduces the exhaust valve lift opened by the cam rocker arm, obstructing exhaust flow. Inadequate exhaust volume then contributes to engine overheating.

What kind of car is referred to as a 'suit-wearing beast'?

'Suit-wearing beast' refers to D-segment cars that appear very business-like and luxurious in appearance, yet possess power comparable to supercars. They look like they're wearing suits, but the engines beneath those suits are extremely violent. Here are some representative models: 1. Audi RS7: The Audi RS7 is equipped with a 4.0T twin-turbocharged engine paired with an 8AT transmission, delivering a maximum power of 605 horsepower. The RS7 is also the top contender among suit-wearing beasts due to its extremely high aesthetics and power. 2. BMW M760Li: The M760 comes with a 6.6T twin-turbocharged engine paired with an 8AT transmission, producing a maximum power of 610 horsepower, with a 0-100 km/h acceleration time of just 3.7 seconds. 3. Maybach S680: Beneath its elegant body lies a 6.0T twin-turbocharged engine paired with a 7AT transmission, delivering a maximum power of 630 horsepower and a 0-100 km/h acceleration time of 4.9 seconds.

Can I get my car inspected without ETC?

It is possible to conduct an annual inspection without ETC, as ETC is not mandatory. ETC is merely a method for fast toll collection at highway exits, aimed at alleviating the pressure of manual toll collection. According to the State Council's regulations, vehicles without ETC or not using ETC in 2020 cannot enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, but this has no direct relation to vehicle annual inspections. Vehicle Annual Inspection Items: Exterior Inspection: Take the exterior inspection form to the designated station. First, verify relevant documents, ensuring the third-party insurance (compulsory insurance) is valid. After document verification, the exterior inspection begins. This check focuses on whether the lights are damaged, if the vehicle's appearance matches the original state, any changes to the suspension, as well as the sunroof, tires, etc. Emission Testing: Queue up and wait for the test. Before testing, staff will conduct a preliminary check, mainly verifying if the engine number matches the one on the vehicle license, briefly inspecting the exterior and condition, then filling out the emission test form. During the test, an inspector will drive the vehicle onto the line. New vehicles usually pass easily. After obtaining a qualified emission test form, proceed to the window to pay and receive the emission compliance label. If the vehicle fails, it must be adjusted at a repair shop and retested, requiring another test fee. Online Inspection: If the exterior inspection passes, queue up for the online inspection. The inspection line checks brakes, headlights (high beam), chassis, etc., taking about 5-10 minutes. After the vehicle exits, a computer-printed form will be issued, listing items like brakes, lights, and horn. Qualified items are marked "0," while unqualified ones are marked "X." Typically, lights and brakes are the common failures. Not to worry—inspection sites have areas for adjusting lights and brakes. After brake adjustments, the vehicle must be retested, but lights only need a stamp after adjustment. Violation Check: Obtain and fill out the "Motor Vehicle Regular Inspection Registration Form" at the query window, which can be collected using the vehicle license. Submit the completed form to staff to check for any violation records. If there are no issues, the form will be stamped "Verified, eligible for inspection." If violations exist, handle them promptly using the violation notice. ETC Deduction Principle: Highways have one or more ETC lanes. Using dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the toll station's ETC lane antenna, the system performs backend settlement with banks via computer networking. This allows vehicles to pass toll stations without stopping, operating on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Low-carbon, as vehicles pass toll stations without stopping, reducing noise and emissions. Reduced wear: Saves costs by minimizing frequent starts and brakes, lowering wear and fuel consumption. Improved efficiency: ETC lanes theoretically increase throughput by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC is more mature and advantageous. More Policy Support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the 13th Five-Year Plan for comprehensive transportation development. More Future Possibilities: Beyond improving ETC installation convenience and usage rates, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with smart transportation developments like vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for car owners, meaning more application scenarios will support ETC.

What does automotive OEM mean?

Automotive OEM refers to suppliers manufacturing parts according to the requirements of automobile manufacturers. These parts can only be supplied to the automaker and its authorized 4S stores, and are not allowed to be provided to other automakers or markets outside the 4S system. Below are relevant explanations: 1. Basic definition: OEM fundamentally means original equipment manufacturing cooperation, commonly known as "white-label production". It means the brand owner doesn't directly manufacture products, but utilizes its mastered "core technologies" to design and develop new products while controlling sales channels. With limited production capacity or even no production lines or factories, to increase output and sales, reduce risks of establishing new production lines, or even to gain market time, they contract other manufacturers to produce the goods, purchase them at low prices, and directly affix their own brand labels. This outsourcing cooperation model is called OEM, the contracted manufacturer is called an OEM supplier, and the products are OEM products. 2. Cooperation models: ODM involves Party B providing technical requirements and commissioning Party A to produce according to these specifications, with Party B purchasing all products. It's a legal cooperative relationship based on contractual authorization. OBM refers to enterprises that manufacture products without their own brands, specializing in accepting OEM or ODM requests from other companies to produce white-label goods.
