BlueCore and Blue Whale are not the same; BlueCore is the first-generation product of the Blue Whale engine. BlueCore generally refers to this engine equipped with DVVT. The Blue Whale series mostly consists of turbocharged engines with DVVT and direct injection. The latest Changan CS75 is equipped with the newly developed Blue Whale 1.5T turbocharged engine, which incorporates direct injection technology, delivering a maximum horsepower of 170 HP and torque of 230 N·m. It uses an Aisin automatic transmission for smoother power output. Below are the key features of the engine in the CS75: 1. Industry-leading high-pressure direct injection technology: Most engines only achieve up to two fuel injections per cycle. However, the new CS75's engine can perform up to five fuel injections in a single stroke. Currently, among mass-produced engines worldwide, it has the highest injection frequency. 2. Precise and efficient scavenging function: The linear oxygen sensor accurately calculates the air-fuel ratio, working in tandem with fine bench calibration and DVVT technology to achieve strong scavenging. This enables closed-loop control of fuel injection under all operating conditions, improving low-end torque by over 20% and reducing the maximum torque speed to 1450 rpm. 3. Low-friction technology for better fuel efficiency: This engine adopts an electronically controlled variable displacement oil pump. By optimizing the system design, it reduces the engine's demand for oil pressure and oil circulation frequency, slows down oil degradation, and adjusts the oil pump displacement for more optimized control strategies. This reduces the oil pump's power consumption, achieving a fuel-saving result of 0.14L.

What is the difference between D and S gear in Golf?

The differences between D and S gear in Golf are as follows: 1. S gear is more responsive than D gear: After shifting into S gear, the upshift is delayed. While driving, if you suddenly press the accelerator, S gear will respond quickly, whereas D gear will take a bit more time. When you press the accelerator, S gear provides a more direct driving experience, while D gear is relatively smoother. 2. S gear consumes more fuel than D gear: While pursuing speed advantages, S gear also maximizes power output. Long-term use of S gear increases air intake, naturally resulting in higher fuel consumption compared to D gear. However, you won't experience the driving pleasure of S gear in D mode. 3. S gear is more powerful for uphill driving: When climbing a slope without switching to S gear, you may notice some unusual noises from the car's engine. This occurs because the engine cannot provide sufficient power at low RPMs, so it's advisable to use S gear for uphill driving.

What Causes the Golf's Central Control Screen to Stop Responding?

When the touch screen of a car's central control panel becomes unresponsive, it is often due to prolonged usage leading to system crashes caused by fragmented files occupying the memory. Another possible reason could be issues with the screen's touch points, which may necessitate a complete replacement. Below is an overview of the Volkswagen Golf: 1. Model Overview: The Volkswagen Golf is a best-selling model under the Volkswagen brand, being the most produced and popular model by Volkswagen, ranking third among the world's best-selling cars. 2. Powertrain: The Volkswagen Golf is equipped with the most advanced 1.4TSI engine and a 7-speed dual-clutch transmission, offering robust performance, which is one of the key reasons for its popularity among consumers. 3. Safety Systems: In terms of active safety, as a compact car with a standard multi-collision brake system, the new Golf effectively prevents injuries from secondary collisions. It is complemented by a lane keeping system, rear traffic alert, fatigue monitoring system, tire pressure monitoring, and newly added rearview camera and blind spot monitoring among other active safety features.

Does Leaving the Car Door Open Drain the Battery?

Leaving the car door open will drain the battery. Here are the relevant details: Battery Drain: Leaving the car door open will cause the battery to lose power. Prolonged periods will deplete the battery. When the car is not in use, all electrical devices inside should be turned off, the doors should be closed, and the central locking system should be engaged. The operation of car doors and windows relies on battery power, so it is best to close all windows before turning off the engine, shut the doors after turning off the engine, and use the long-press lock button method to secure the doors after leaving the car. Before Turning Off the Engine: Turn off the air conditioning and audio system before shutting down the engine. The air conditioning system involves the compressor, blower, and audio—these are high-power electrical devices. Not turning them off before shutting down the engine will place a heavy burden on the battery, potentially causing damage. Long-Term Parking: The car battery will automatically discharge during prolonged periods of inactivity. The vehicle should be used regularly to avoid issues with automatic battery discharge.

Do You Need to Press the Accelerator When Shifting Gears?

You do not need to press the accelerator when shifting gears. Normally, when shifting gears, you should simultaneously depress the clutch and release the accelerator. At the moment the power is cut off, the engine speed begins to drop. If the accelerator is released too early, the engine speed may drop first, potentially causing engine braking and resulting in jerking. Below are the relevant details: 1. Transmission shifting process: During the gear shifting process, the transmission must ensure that the circumferential speeds of the pair of gear teeth to be meshed are equal (i.e., synchronized) to smoothly engage and shift into gear. If the gear teeth are not synchronized and forced into gear, it will inevitably cause impact and noise due to the speed difference between the two gear teeth. This not only makes shifting difficult but also affects the lifespan of the gear teeth, accelerating wear at the tooth ends and even leading to tooth breakage. 2. Introduction to the transmission: The function of the transmission is to change the speed and torque from the engine. It can fixedly or stepwise alter the transmission ratio between the output shaft and the input shaft. Also known as the gearbox, the transmission consists of the gear shifting mechanism and the control mechanism.

Is the dashboard backlight of the new Bora sensor-activated during the day?

The dashboard backlight of the new Bora does not illuminate during the day. Below are specific details about the Bora: 1. Background: The Bora is a classic model under the Volkswagen brand. The interior of the new Bora draws inspiration from the high-end model Magotan, featuring a simple and symmetrical design style that highlights a steady and grand atmosphere. 2. Exterior: The new Bora adopts Volkswagen's family-style front face design, with distinct layers in the headlights that use a wing-shaped design, creating a strong three-dimensional effect. The rear design has changes in the contour and light clusters compared to the current model, and the body lines are significantly different from the current Bora, becoming more fluid, while also featuring a newly designed aluminum alloy wheel style. 3. Powertrain Configuration: In terms of configuration, based on a simple comparison by the offline site editor, the new Bora differs from its sister model Lavida in the same segment, but they are on par with each other. As previously mentioned, the powertrain remains unchanged, and it can now be confirmed that the top-end model is still equipped with a 1.4TSI engine paired with a DSG transmission.

What are the differences between lane change signals and slow down signals?

The differences between lane change signals and slow down signals are as follows: 1. The slow down signal involves waving the hand horizontally downward, while the lane change signal involves waving the hand vertically to the left. 2. The lane change signal is one of the traffic police hand signals, indicating that vehicles should vacate the designated lane and slow down. The right arm is extended forward with the palm facing left, and the right arm swings horizontally to the left. 3. The new eight types of traffic police hand signals include: stop signal, go straight signal, left turn signal, left turn waiting signal, right turn signal, lane change and slow down signal, slow down signal, and signal for vehicles to pull over. 4. Among the original 11 hand signals, the rarely used and redundant two stop signals and two go straight signals were merged into one stop signal and one go straight signal, respectively. The 'large left turn signal' was canceled, while the frequently used and well-known hand signals familiar to traffic participants were retained.
