If the water temperature gauge doesn't rise, it is likely due to a malfunction of the water temperature sensor. The water temperature sensor is installed in the water jacket of the engine block or cylinder head, directly contacting the coolant to measure the temperature of the engine coolant. If the water temperature sensor fails or malfunctions, the engine ECU will detect that the output signal from the water temperature sensor is unreliable. Below are the hazards of low water temperature in cars during winter: 1. It can lead to incomplete fuel combustion: reducing the engine's efficiency. 2. Incomplete fuel combustion causes carbon deposits: increasing fuel consumption and polluting the environment. 3. Prolonged operation of the vehicle at low temperatures: accelerates wear and tear on internal engine components.

Should Left-Turning Vehicles Yield to Right-Turning Vehicles?

If two vehicles are traveling in opposite directions, the right-turning motor vehicle must yield to the left-turning vehicle. This is because left-turning vehicles have a longer trajectory. If the right-turning vehicle does not yield, the left-turning vehicle would have to stop in the middle of the intersection for an extended period, disrupting the normal flow of other vehicles. Therefore, left-turning vehicles have the right of way. According to traffic regulations, if a collision occurs because the right-turning vehicle fails to yield, the right-turning vehicle bears full responsibility. In addition to the "right-turning vehicles yield to left-turning vehicles" rule, when motor vehicles pass through intersections without traffic signals or police direction, they must also adhere to the following rules: Right-of-Way Principle: When two vehicles approach from intersecting directions and both intend to go straight, the vehicle on the left must yield to the vehicle on the right. Turning Vehicles Yield to Straight Vehicles: At an intersection, vehicles turning left (or right) must yield to vehicles going straight. If there are traffic signs or markings indicating priority, the vehicle with the right of way proceeds first.

How Often Should a Turbocharger Be Cleaned?

Turbochargers generally need to be cleaned approximately every 10,000 kilometers, with a typical service life of around 5-6 years. Below is relevant information about turbochargers: 1. Increasing Air Intake: A turbocharger is essentially an air compressor that boosts intake by compressing air. With prolonged use, the turbo shaft can experience oil seepage under high temperatures, which combines with impurities, dust from the air, and carbon deposits from recycled exhaust, forming accumulated sludge. This sludge can impair the performance of turbocharged vehicles. 2. Working Principle: The turbocharger utilizes the inertial force of exhaust gases expelled by the engine to drive the turbine in the turbo chamber. The turbine, in turn, drives the coaxial impeller, which compresses air delivered through the air filter pipeline, forcing it into the cylinders under increased pressure. As the engine speed rises, the exhaust gas velocity and turbine speed increase synchronously, allowing the impeller to compress more air into the cylinders. The heightened air pressure and density enable the combustion of more fuel, and by adjusting the fuel quantity and engine speed accordingly, the engine's output power can be enhanced.

What to Do If You're Afraid to Drive After Just Getting Your License?

Here are some suggestions for new drivers who are afraid to drive after just getting their license: 1. Minimize lane changes; reduce the number of times you switch lanes. Even when you need to merge or change lanes, it's best to start doing so 300-500 meters in advance. Always check your rearview mirror early to give following vehicles enough space. Never slow down and change lanes right at an intersection, as this can easily lead to rear-end collisions or scrapes. 2. Anticipate: Predict traffic conditions ahead by frequently observing the vehicles in front and the adjacent lanes. Master throttle control—if you anticipate needing to slow down, ease off the accelerator early to prepare for braking, reducing the need for sudden stops. 3. Observe: Regularly check all three rearview mirrors. While it's easy to predict the road conditions ahead, you can only monitor vehicles behind you through the mirrors. Pay extra attention to fast-approaching vehicles or those tailgating too closely. 4. Route: For manual transmission drivers, it's best to practice starting and stopping in quiet areas to minimize stalling when driving on the road.

What causes the car to deviate during Subject Three driving test?

The main reasons for a car deviating during the Subject Three driving test are threefold: 1. Driving tire pressure: Inconsistent driving tire pressure causes uneven wear between the driving wheels and the ground, leading to deviation. 2. Suspension system failure: Issues such as suspension damage, deformation, or misalignment can cause the car to deviate. 3. Unequal wheelbase on both sides: When the car is moving, it will tend to deviate towards the side with the shorter wheelbase. Below is relevant information: 1. Driving phenomenon: Car deviation refers to the tendency of a car to automatically steer left or right when driving at a constant speed on a flat, straight, dry, and clean cement or asphalt road after releasing the steering wheel, resulting in the centerline of the front and rear axles not aligning with the centerline of the driving trajectory. 2. Influencing factors: Due to factors such as car structural design and manufacturing precision, a car that does not deviate at all does not exist. Typically, if a car deviates more than 5 meters when driving 1000 meters on a flat straight road, it can be considered as deviation.

What to do when changing license plates for ETC?

Remove the ETC device and ETC card from the vehicle, and bring your ID card, new license plate vehicle registration certificate, and driver's license to an ETC service center or ETC processing point to complete the modification procedures. The staff will input the new information into the ETC electronic tag, reactivate it, and after reinstallation, it can be used. Below is relevant information: 1. The ETC device is dedicated to a specific vehicle. However, one ETC card can be bound to multiple vehicles for payment. An ETC card already bound to another vehicle can be used on other vehicles. Therefore, if the license plate is changed and the ETC device cannot be used, you can take it to an ETC service center or ETC processing point to cancel the ETC. After successful cancellation, reactivate the ETC device and input the new information, and bind the ETC card to the new license plate for use. 2. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically used for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and some sections of urban centers to alleviate urban traffic congestion.

What is the difference between VCU and ECU?

VCU and ECU have the following differences: 1. VCU: The VCU is the core electronic control unit that implements vehicle control decisions. It is generally only equipped in new energy vehicles, while traditional fuel vehicles do not require this device. The VCU determines the driver's driving intention by collecting signals from the accelerator pedal, gear, brake pedal, etc. By monitoring vehicle status (such as speed, temperature, etc.), the VCU processes this information and sends control commands for the vehicle's operating state to the powertrain and battery system, while also controlling the working mode of the on-board auxiliary power system. The VCU has functions for diagnosing, protecting, and storing faults in the entire vehicle system. 2. ECU: The ECU controls the fuel mixture (air-fuel ratio) and spark timing (ignition advance and duration) based on feedback from sensors connected to the engine. The control of fuel mixture and spark timing is quite complex. The ECU needs to gather data from multiple sensors to achieve optimal system control. The ECU must monitor ground speed, engine speed, crankshaft position, air quality (oxygen content), engine temperature, engine load (such as when the air conditioning (A/C) is on), throttle position, throttle change rate, transmission gear, exhaust emissions, and more.
