ACC on a car stands for Adaptive Cruise Control, which is an intelligent automatic control system developed from the existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects speed signals. The adaptive cruise system only works when the vehicle speed exceeds 25 km/h, and when the speed drops below 25 km/h, manual control by the driver is required. Through system software upgrades, the adaptive cruise control system can achieve stop-and-go functionality to handle frequent stops and starts in urban driving conditions.

What Causes High Engine RPM Without Corresponding Speed Increase in Motorcycles?

This situation may be caused by clutch slippage. The engine RPM can increase, but the vehicle speed does not correspondingly rise. If the riding method is correct, the likely cause is clutch slippage. First, check the engine oil condition, whether the clutch cable is too tight, and if the clutch release rocker arm is stuck and not returning to position. If these aspects are normal, then inspect the wear condition of the clutch plates and whether there are issues with the clutch springs. Below is relevant information about engine RPM: 1. Introduction: The level of engine RPM relates to the number of work cycles per unit time or the magnitude of the engine's effective power, meaning the engine's effective power varies with different RPMs. Therefore, when indicating the size of the engine's effective power, the corresponding RPM must also be specified. The effective power and its corresponding RPM specified on the engine's product label are referred to as the rated power and rated RPM, respectively. The operating condition of the engine at rated power and RPM is called the rated condition. Rated power is not the maximum power the engine can produce; it is the maximum usable limit of effective power determined based on the engine's application. For the same engine model, the rated power value may differ depending on its use. Effective torque also varies with engine conditions. Therefore, the maximum torque a vehicle engine can output and its corresponding RPM serve as an indicator for evaluating the engine's dynamic performance. 2. RPM Measurement: Typically, an RPM sensor is used, corresponding to the signal teeth on the flywheel, to measure the engine's RPM.

What is the fuel consumption of the Nissan Murano?

The comprehensive fuel consumption of the Nissan Murano is 8.3-8.4L/100km. There are currently 3 models of the Nissan Murano on sale. The fuel consumption of the Elite version is 8.3L/100km, while the Intelligent Luxury version and Intelligent Leading version have a fuel consumption of 8.4L/100km. The above figures are based on the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than these values, ranging from 8.6-9.1L/100km. Specific factors affecting a car's fuel consumption are as follows: Vehicle weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine and a weight of around 1.2 tons has a fuel consumption of about 7.5 liters (calculated under full load conditions), while an SUV weighing around 1.5 tons consumes about 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag coefficients increase fuel consumption during driving. Cars with better aerodynamics have lower drag coefficients, leading to lower fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point. Maintaining the car's speed within this torque output range can significantly reduce fuel consumption. Generally, for small-displacement cars, this is around 70 km/h, while for larger-displacement cars, it is about 100 km/h. Staying within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before red lights can increase fuel consumption.

Can New Energy Vehicles Get Blue License Plates?

New energy vehicles cannot get blue license plates; they must use green license plates, which are special plates designated for new energy vehicles, with green symbolizing environmental protection. Types of new energy vehicles include: pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles. Characteristics of new energy vehicles: 1. They use natural gas, petroleum gas, hydrogen, or electricity as power sources, saving fuel energy; 2. They reduce exhaust emissions, produce no tailpipe pollution (hydrogen vehicles emit only water, causing no environmental harm); 3. They employ new technologies and structures for higher efficiency; 4. They operate with low noise.

What are the precautions for new energy vehicles?

Precautions for new energy vehicles are: 1. Before driving, check whether the battery power is sufficient, whether the braking performance is good, whether the screws are loose, and any faults should be repaired and eliminated in time; 2. When parking, the power switch must be turned off, the key must be pulled out, the gear switch must be turned to the neutral position, and the handbrake must be pulled up; 3. When children play in the car, the key switch must be pulled out; 4. Charging should be carried out in a place where children cannot reach; 5. When repairing or replacing the charging fuse, the power plug must be unplugged; 6. When repairing or replacing the battery or electrical appliances, the main power switch must be turned off before operation; 7. Before driving a new energy vehicle, it is necessary to check whether the doors are closed tightly; 8. In case of fire caused by an accident or other reasons, the main power switch should be turned off immediately.

How to Install a Dash Cam?

The installation method of a dash cam: First, install the dash cam on the front windshield. The dash cam comes with a suction cup, which can be directly attached to the windshield. Then, route the power cable along the edge of the windshield and secure the wire. Finally, connect the power charging device to the car's cigarette lighter. A dash cam is an instrument that records images, sounds, and other related information during vehicle travel. After installing a dash cam, it can record the entire driving process, including video and audio, which can serve as evidence in traffic accidents. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. Additionally, it can be used at home as a DV to capture life's moments or as a home surveillance device.
