Methods to distinguish the intake and exhaust camshaft bearing caps of Geely Emgrand: The camshaft has letters marked on it, where IN represents intake and EX represents exhaust. The function of the automobile camshaft is to control the opening and closing of valves. Here is more information about Geely Emgrand: 1. The curb weight of Geely Emgrand is about 1.4 tons. The new Emgrand is equipped with a 1.3-liter turbocharged engine. The 1.3T engine features high torque at low speeds and strong acceleration performance, paired with a mature and stable CVT transmission. 2. Emgrand is a compact sedan under Geely.

I've worked on the Geely Emgrand engine multiple times, and the key to distinguishing between intake and exhaust camshaft bearing caps lies in their positions and markings. The intake bearing caps are typically located towards the front of the engine or on the intake manifold side, often engraved with 'IN' or intake symbols, and feel relatively smooth to the touch. The exhaust bearing caps are positioned at the rear or near the exhaust manifold, marked with 'EX' or exhaust symbols, and may be designed slightly thicker to withstand high temperatures. During disassembly, it's crucial to take photos with your phone or mark the original positions with a marker pen to avoid confusion. Installing them incorrectly can cause the camshaft to jam, leading to engine knocking or excessive noise. I recommend referring to the Geely official manual diagrams for guidance. During maintenance, take the opportunity to check lubrication. If there are no markings, measure the dimensions—the intake bore is usually larger to ensure proper airflow. Remembering these small details can save you a lot of trouble and repair costs.

Are Plug-in Hybrids Considered New Energy Vehicles?

Plug-in hybrids belong to the category of new energy vehicles. Plug-in hybrid vehicles currently serve as a transitional model between gasoline-powered cars and pure electric vehicles, with the purpose of enabling more people to understand and use new energy vehicles. Due to the range limitations of pure electric vehicles, plug-in hybrid models have emerged to compensate while also promoting the construction of charging infrastructure. Below is an introduction to the types of plug-in hybrid electric vehicles: Series Plug-in Hybrid: Also known as range-extended hybrids. In this configuration, the engine does not directly drive the vehicle. Instead, the engine first drives a generator to produce electricity, which then powers the electric motor to drive the car. This results in a longer energy transfer chain and relatively lower overall efficiency. Parallel Plug-in Hybrid: In this type, both the engine and the electric motor can drive the vehicle. It offers multiple power transmission modes, better dynamic performance, and a simpler structure, making it a widely adopted mainstream technical solution. Power-Split Plug-in Hybrid: Also referred to as hybrid parallel-series configuration. This type generally requires two motors (one generator and one electric motor) along with a planetary gear set for power distribution.

What is the reason why the Surui one-button start makes a sound but then doesn't respond?

The reason why the Surui one-button start makes a sound but then doesn't respond is that the internal motor of the steering lock is stuck, causing insufficient induction and preventing the car from starting. Relevant information about the Surui is as follows: 1. Power: The Surui is equipped with a TI power engine that combines turbocharging and direct fuel injection technology. The new power system will significantly improve the overall vehicle performance. Looking at the domestic car market, consumers have a strong preference for "T" power, and the letter "T" embedded at the rear of the car has gradually become a symbol of high technology, strong power, and more fashion. With the launch of the BYD G6 featuring "TID" technology, the "T stage" is no longer dominated by Volkswagen alone, as BYD has become the first domestic car brand to master world-class commercial engine technology. 2. Exterior: The Surui's front face features a dual-chrome strip design that blends seamlessly with the crystal-clear willow-leaf combination headlights; the diamond-contour taillights perfectly connect with the waistline that runs from front to rear, making the body more harmonious, smooth, dynamic, and stylish. It is reported that the full-body outer covering sheet metal molds of the Surui are designed and produced by Japan's Ogihara factory, and its main welding line also adopts advanced patented technology from Germany's ABB company, with welding performed by robots, achieving a higher level of craftsmanship. The Surui's body dimensions of 4680mm × 1765mm × 1490mm and an ultra-long wheelbase of 2660mm outperform its peers, creating a more spacious and comfortable driving space, placing it in the A+ class sedan category.

What Are the Differences Between New and Used Cars?

New cars are purchased from car dealerships and are vehicles that come directly from the production line. Used cars are vehicles that have been registered for the first time and then transferred, possibly multiple times. 1. Different Definitions: (1) New cars mainly refer to vehicles purchased for the first time from a dealer, including those whose transfer count is also the first. These vehicles are bought directly from the production line, and after registration, ownership is designated to the first owner. (2) Used cars, by definition, are vehicles transferred from previous owners, so the transfer count is generally two or more. Professionally, they are also referred to as 'pre-owned vehicles,' primarily indicating motor vehicles that have not reached the state-mandated scrapping time and can still be used. Transferring a used car represents the transfer of ownership, disposal rights, and other powers. 2. Different Purchase Channels: New cars are those seen in traditional 4S stores. The purchase channels for used cars are more diverse than for new cars. Car enthusiasts can choose used cars from various channels such as used car markets, private sellers, and vehicle auction transactions.

How to Check if ETC is Successfully Activated?

There are two ways to check whether the ETC has been activated: Simply insert the ETC card into the ETC electronic tag, and you can click to view after insertion. If the ETC card account balance is displayed, it means the activation is successful. When passing through the ETC lane, a beep sound indicates successful deduction, the barrier will automatically rise, and it can be used normally. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Sign Invalid, Please Insert Card," indicating the device is normal. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the protective film of the OBU back adhesive and stick it to the installation position. Press with your hand for 2-3 minutes to remove air bubbles. Insert the ETC card with the front facing the driver and the back facing the front glass. The chip should be inserted into the OBU device. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Cost-saving: Reduces expenses, decreases the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on toll fees; Improved efficiency: The efficiency of passing through ETC lanes can theoretically increase by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
