What causes intermittent fuel cut-off while driving and then recovery?

This issue could be caused by a faulty throttle pedal position sensor or throttle position sensor. Malfunctions in the idle control valve or engine control unit (ECU) may also lead to this phenomenon. It is recommended to contact a 4S dealership for inspection and repair. Relevant information about engine fuel cut-off: 1. Fuel cut-off protection working principle: For small and medium-sized diesel engines, the fuel cut-off protection usually involves installing a small cylinder on the throttle linkage. The piston of this small cylinder is connected to the throttle linkage. When the diesel engine experiences a loss of lubricating oil pressure, the pressure detection device installed in the lubricating oil pipeline system will activate the compressed air switch. This allows compressed air to travel through the pipeline to the small cylinder, pushing the piston to move the throttle linkage to the extreme fuel cut-off position, completely stopping the fuel supply and shutting down the engine. 2. Fuel cut-off protection working method: Generally, this refers to the engine control module (ECM) temporarily stopping the operation of the fuel injectors when it detects that the engine is operating outside the normal range or identifies an abnormal condition. This prevents fuel from being injected into the cylinders, causing the engine speed to drop or heat generation to decrease sharply, thereby protecting the engine. When the ECM detects that the speed has fallen back to a safe range or the water temperature has returned to normal, fuel injection resumes, and the engine returns to normal operation.

Where is the Vitara's rearview mirror heating located?

Vitara's rearview mirror heating is located below the electric mirror adjustment button on the driver's seat, which is a square button. Additional information: 1. Principle of rearview mirror heating: It uses electric heating wires on the mirror surface to warm up and evaporate rain or fog until it disappears, ensuring clear visibility. The heated rearview mirror operates via heating wires embedded behind the mirror, gradually raising the mirror temperature above 40°C to accelerate the evaporation of moisture and maintain a clear view. 2. Usage scenarios: When driving in foggy, rainy, or snowy conditions, moisture can obscure the driver's view of the side and rear, requiring frequent cleaning by reaching out the window. This is not only inconvenient but also compromises driving safety, and the effect is temporary as fog and rain quickly blur the mirror again. With a heated rearview mirror, the driver simply needs to press the defrost button, and the mirror will heat up (usually around 45°C), removing accumulated fog or frost from the surface. This ensures clear visibility, significantly improving convenience and enhancing driving safety.

What principle does the engine operate on?

Engine working principle is: 1. Four-stroke gasoline engine: The working cycle of a four-stroke gasoline engine consists of four piston strokes, namely the intake stroke, compression stroke, power stroke, and exhaust stroke. 2. Four-stroke diesel engine: The working principle of a four-stroke diesel engine is the same as that of a four-stroke gasoline engine, also consisting of intake, compression, power, and exhaust strokes. The difference is that the diesel engine's intake stroke draws in pure air, and near the top dead center of the compression stroke, the fuel injector sprays diesel into the combustion chamber. 3. Two-stroke engine: The engine cylinder block has three holes, namely the intake hole, exhaust hole, and scavenging hole, which are closed by the piston at specific times.

Is Adaptive High Beam Useful?

Automotive adaptive high beam lighting system is a headlight system that can automatically switch between high and low beams to adapt to changing driving conditions. It represents one of the latest international advancements in automotive lighting technology, significantly enhancing nighttime driving safety. Here are the key details: 1. Function: The system uses a camera mounted on the rearview mirror to detect oncoming vehicles up to 400 meters ahead. 2. Automatic Switching: When an approaching vehicle is detected, the system selectively blocks portions of the high beam to avoid dazzling the other driver, ensuring clear visibility without manual intervention. Once no vehicles are detected ahead, it automatically switches back to high beam mode.

Can people over 70 still drive?

People over 70 can still drive. The details are as follows: 1. No age limit for driving C1 vehicles: There is no age limit for a C1 driver's license, but drivers aged 70 or older must have their license checked annually. 2. Submission of a driver's health certificate required: Drivers must submit a 'driver's health certificate' within 30 days after the end of the scoring period. Failure to submit will result in the license becoming invalid the following year. Additional information on the application and use of motor vehicle driver's licenses: According to Article 57 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses,' motor vehicle drivers should apply for license renewal at the vehicle management office where the license was issued or another office 90 days before the license expires. When applying, the following documents must be submitted: 1. The driver's identity proof. 2. The motor vehicle driver's license. 3. A health condition certificate issued by a county-level or higher medical institution or a military medical institution at the regimental level or above. For applications for small automatic passenger vehicles for the disabled, a health condition certificate issued by a specialized medical institution designated by the provincial health authority must be submitted.

What does low tire pressure mean?

Tire low pressure means that the tire pressure is too low. When this situation occurs, it should be inflated in time. The following is the extended information: 1. When the tire pressure is too high or too low: The tire pressure should not be too high or too low. If the pressure is too low, the tire will show wave deformation during high-speed driving, which will reduce the service life of the tire and also increase the chance of a tire blowout. If the pressure is too high, it will reduce the contact area between the tire and the ground, which will affect the car's handling and driving stability. 2. Tire replacement time: Tires are rubber products, and rubber products will age after long-term use, so tires are a vulnerable part that needs to be replaced regularly. Generally, tires need to be replaced every four years, so it is recommended to replace the tires every four years. When buying new tires, be sure to check the production date clearly, as tires also have a shelf life. Generally, the shelf life of unused tires is three years. If the tires have been produced for more than three years, do not purchase them.
