If the engine runs basically normally without load, but accelerates slowly under load, the car lacks power when going uphill, and still feels insufficient power when the accelerator pedal is pressed to the bottom, the speed cannot be increased, and the maximum speed cannot be reached. The main causes of the failure are: (1) The air filter is blocked. (2) The throttle is improperly adjusted and cannot be fully opened. (3) The fuel pressure is too low. (4) The fuel injector is blocked or atomized poorly. (5) The water temperature sensor is faulty. (6) The air flow meter is faulty. (7) The ignition timing is improper or the high-voltage spark is too weak. (8) The engine compression pressure is too low.

What Causes a Sudden Loss of Power Storage in a Car Battery?

When a car battery fails to hold a charge, it is most likely due to deep discharge. The reasons for the loss of power storage and the hazards of battery depletion are as follows: Reasons: When the vehicle is turned off, certain devices may remain operational, continuously draining the battery and accelerating its degradation. Another common cause is the aging of the alternator belt. The engine directly drives the alternator via the belt, and the generated electricity is then rectified and stabilized before charging the car battery. Hazards of Battery Depletion: Unstable engine idling, reduced actual fuel injection, weakened ignition energy, inability to disable the anti-theft alarm, locking of the audio system, and malfunctioning of related systems, among others.

Is a Power of Attorney Still Required for Out-of-Town Vehicle Inspection?

Out-of-town vehicle inspection does not require a power of attorney. The inspection items include: 1. Checking whether the engine, chassis, body, and their ancillary equipment are clean, complete, and effective, whether the paint surface is uniform and aesthetically pleasing, whether the main assemblies have been replaced, and whether they match the initial inspection records; 2. Testing whether the vehicle's braking performance, lighting, exhaust, and other safety features comply with relevant regulations; 3. Verifying whether the vehicle has been modified, remodeled, or altered, and whether the driving license, license plate, and all vehicle file registrations match the actual condition of the vehicle; 4. Checking for any damage, alterations, or illegible characters on the license plate, driving license, and the enlarged license plate characters printed on the vehicle, and determining whether replacement is necessary.

What is the fuel consumption of the Trumpchi GS3?

The fuel consumption of the Trumpchi GS3 1.5L displacement automatic transmission version is 8.5L per 100 kilometers; the manual version consumes 7.7L per 100 kilometers; the 1.3T displacement version consumes 8.8L per 100 kilometers. The following are specific reasons for high fuel consumption in cars: Affected by temperature: Fluctuations in fuel consumption occur, especially in winter when lower temperatures lead to increased fuel consumption. Vehicle not maintained for a long time: Dirty engine oil and air filters can also cause increased fuel consumption. Dirty engine oil leads to poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, resulting in higher fuel consumption. Excessive carbon buildup in the vehicle: Carbon buildup in areas such as the throttle body, fuel injectors, intake manifold, and piston tops can lead to incomplete combustion, thereby increasing fuel consumption.

When Does the Turbo Kick In?

Turbocharged engines typically engage at 1500-2000 RPM. 1. The exact engagement point of turbocharging is related to engine displacement. Larger displacement engines have lower engagement RPM. For example, a 1.4L engine engages around 2000 RPM, a 1.8L around 1500 RPM, and a 2.0L around 1000 RPM. 2. The main function of turbocharging is to increase engine air intake. By increasing air intake, turbocharging enhances engine power and torque, making the vehicle more powerful. When a turbocharger is installed, the engine's maximum power increases by over 40% compared to without one. When the turbo engages, the power delivery becomes more aggressive, creating noticeable acceleration force (commonly felt as "push-back" sensation), which also serves as an indicator of turbo engagement.

What are the impacts on car owners if they do not scrap their vehicles?

Failure to scrap a vehicle may affect the car owner's driver's license renewal or annual inspection. Here is relevant information about not processing vehicle scrappage: 1. Negative impacts: If the owner sells the car as scrap, some illegal elements may retain vehicle identification marks such as the engine number and chassis number, and install them on other vehicles. If such reassembled vehicles are involved in accidents, authorities can trace these marks back to the original vehicle owner, who will undoubtedly face troubles and unnecessary losses. 2. Other regulations: Article 13 of the Road Traffic Safety Law: For motor vehicles registered for road use, regular safety technical inspections shall be conducted in accordance with laws and administrative regulations, based on factors such as vehicle purpose, passenger/cargo capacity, and service life.
