How Many Generations of Bentley Flying Spur Are There?

2005-2013 First-Generation Continental Flying Spur In 2003, Bentley's two-door GT car, the Azure, was discontinued. The Bentley Continental GT was then launched, marking Bentley's flagship model after joining the Volkswagen Group. It featured a 6.0-liter W12 engine shared with the Audi A8 and Volkswagen Phaeton 6.0, but with added twin turbos, boosting horsepower to 552 hp and a top speed nearing 320 km/h. The car was equipped with a 6-speed Tiptronic transmission and 4Motion all-wheel-drive system, becoming Bentley's main model at the time. On March 5, 2013, the second-generation Flying Spur made its global debut at the Geneva Motor Show, establishing new design features for Bentley's high-performance four-door sedans. The body structure was reinforced at the B-pillars, sills, and front cross members, with deformable elements integrated into the floor. The fenders were formed using superplastic molding technology, making them lighter. The trunk lid, which housed the main antenna for the vehicle's electronic system, was made of a high-molecular synthetic material, further reducing weight. The torsional rigidity of the body was 36,500 Nm/degree, a 4% improvement over the previous generation. The sleek and streamlined design gave the new Flying Spur exceptional aerodynamic properties for a large four-door sedan, with a drag coefficient of just 0.29, ensuring superior emissions performance. Thanks to weight reduction measures across multiple areas of the car, despite more improvements, enhanced technical specifications, and reinforced structural design, the new Flying Spur was 50 kg lighter than the first-generation model. The third-generation Flying Spur was officially unveiled on June 11, 2019, with orders opening that autumn and deliveries starting on February 4, 2020. This generation introduced an all-wheel steering system for the first time, along with a new chassis made of aluminum and composite materials, a 48-volt electrical architecture, and a fresh design language. It was built with the latest powertrain and chassis technologies. Standard features included adaptive air suspension, torque vectoring by brake, dynamic drive control, and electric power steering. Additionally, customers could opt for the industry-leading 48-volt active roll control system—Bentley Dynamic Ride—and electronic all-wheel steering to further enhance the driving experience.

Cummins K38 Valve and Injector Adjustment Sequence

I. Cummins K38 Engine Valve Adjustment Sequence: 1. Cylinder-by-Cylinder Method: This method requires rotating each cylinder to its compression top dead center (TDC) position before adjusting its valve clearance. It necessitates identifying each cylinder's compression TDC and memorizing the engine's firing order for different vehicle models. 2. Two-Step Adjustment Method: This approach completes all valve adjustments in two operations. It's simple and highly efficient – even for engines with numerous cylinders, only two adjustments are needed to complete the process. II. Cummins Engine Valve Clearance Adjustment Method: The Cummins K38 engine maintains a specific clearance between valve stem ends and their transmission components to compensate for thermal expansion, ensuring proper engine operation. When valves are fully closed, this gap between valve stems and rocker arms is termed valve clearance. Below are the adjustment procedures for Cummins K38 engine valve clearance. Hazards of Improper Clearance: Excessive Clearance: ① Increased engine noise; ② Reduced valve travel decreases valve opening, leading to insufficient intake/exhaust flow that severely impacts engine power and lifespan; ③ Accelerated wear in valve train components due to increased impact. Insufficient Clearance: ① Thermal expansion may force valves open, causing leakage and power loss; ② Severe carbon buildup or burning on valve seats, potentially causing valve-to-piston contact. Valve Clearance Inspection: After 1 year or 1,500 hours of operation, valve clearance must be inspected and adjusted. Using a standard feeler gauge, proper clearance should show slight resistance when inserted. (Standard clearance: intake valve 0.28mm, exhaust valve 0.58mm) Before inspection, remove engine components obstructing valve cover access (e.g., crankcase breather tube), then detach valve cover fastening screws and carefully remove the cover. Injector Travel Adjustment Methods vary by type: Top-stop injectors: Torque method (zero-clearance); Non-top-stop injectors: Dial indicator method (travel measurement) Valve Adjustment Procedure: 1. Loosen lock nuts on adjustment bolts. Insert appropriate feeler gauges between rocker arms and crossheads (intake 0.28mm, exhaust 0.58mm). Tighten adjustment bolts until rockers contact gauges, then secure with 54-61 N·m torque. (Injector travel must be adjusted before valve clearance for each cylinder). 2. Loosen injector rocker arm lock nuts. Tighten adjustment bolts until plungers contact injector cups, then rotate 15° further to purge oil. 3. Back off adjustment bolts one turn, then advance until zero clearance is achieved (plunger should rotate freely with slight resistance). Tighten lock nuts to 54-61 N·m. 4. Following firing order (1-5-3-6-2-4), rotate engine to next timing mark (Point B) to adjust #5 cylinder valves and #3 cylinder injector plunger travel.

How to Use the Remote Key to Lower Windows with One Click?

After unlocking the vehicle, press and hold the unlock button on the remote key, and the vehicle's windows will lower. If you stop midway, the window lowering will pause; pressing the button again will continue the process until the windows are fully lowered. Here are some additional details: 1. The one-touch window-up feature only works on the driver's side door; the other three doors are not equipped with this function. Besides cost reduction, manufacturers also consider passenger safety. 2. The one-touch window control is primarily designed to prevent drivers from being distracted while operating the windows during driving, thereby reducing the risk of traffic accidents and enhancing safety.

What is the Function of Lane Departure Warning System?

Lane Departure Warning System (LDWS) functions by alerting the driver to reduce traffic accidents caused by lane departure. The system consists of an image processing chip, controller, sensors, etc. When the LDWS is activated, the camera continuously captures the lane markings, and the image processing system determines the vehicle's position parameters within the current lane. If a lane departure is detected, the sensors promptly collect vehicle data and the driver's operational status, after which the controller issues an alert signal. The entire process is completed in approximately 0.5 seconds, providing the driver with ample reaction time.

Where is the USB port in the Geely Boyue?

Geely Boyue's USB port is located inside the center armrest console, with a specification of 12V. Here is some information about the USB port: 1. Most in-car USB ports are designed for data transfer. Although they show charging when connected, the current is very small, only about 0.5A. 2. When the driver is listening to music or using mobile navigation, the power consumption within the same time period actually exceeds the charging amount. If the battery level decreases instead of increasing, it is recommended to stop using the USB port for charging.

Why do the headlights automatically turn on when unlocking the car with the key?

When the headlights automatically turn on upon unlocking the car with the key, it is likely because the light control has been set to the automatic mode. This situation usually occurs when the headlights are controlled by a light-sensitive trigger switch. Below is some related information about remote keys: 1. Introduction: A remote key utilizes the wireless remote control function of the central locking system, allowing you to unlock or lock the doors from a distance without inserting the key into the lock. 2. Working Principle: Simply put, the key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the unlocking or locking action.
