4A15K1 engine is independently developed and produced by GAC Motor Co., Ltd. This engine is quite impressive, featuring combustion control technology, VVT on both intake and exhaust sides, and equipped with an electronically controlled variable displacement oil pump and a small inertia turbocharger. It is truly commendable for a Chinese brand enterprise to mass-produce such a product through independent research and development. In terms of power performance parameters, it is not inferior to its benchmark engine. Many technologies adopted by this engine are mature technologies used by mainstream engines in the market, which can improve the working efficiency and performance of the engine to a certain extent, such as low-inertia turbocharger, DVVT, variable displacement oil pump, roller rocker arm, etc. In some technical details, the persistence of GAC engineers in product performance can be seen, such as the independently developed oil-gas separator, aluminum alloy fender, lightweight piston/connecting rod, forged crankshaft, etc.

What is the Online Study for Point Deduction Reduction on Driver's License?

According to Article 5 of the Notice issued by the Ministry of Public Security on April 1, 2022, regarding the "Work Regulations on Reducing Points for Road Traffic Safety Violations through Accepting Traffic Safety Education (Trial)" (Public Transport Management [2020] No. 14): Motor vehicle drivers who apply to participate in traffic safety education to reduce points for traffic violations must participate in corresponding road traffic safety laws, regulations, and related knowledge learning, examinations, or traffic safety public welfare activities according to their highest permitted driving license type and meet the relevant requirements to apply for point reduction. The "Study for Point Deduction Reduction" is a measure for drivers holding a driver's license who have been penalized with points due to traffic violations. After participating in online traffic safety education and passing the examination, their points can be reduced. This is a convenient traffic management measure uniformly deployed by the Traffic Management Bureau of the Ministry of Public Security. Function: The "Study for Point Deduction Reduction" reduces existing points on the driver's license rather than adding points or replacing penalty points. The points obtained through free study are used to clear the penalty records. For example, if a driver is penalized with 6 points, passing the point reduction examination can clear these 6 points, starting fresh. Regulations: The number of points that can be deducted after point reduction depends on how many points the driver had before the study, but the cumulative points cannot exceed 11. Whether or not the driver participates in point reduction, the driver's license only has 12 points. The point reduction only reduces existing points and does not increase the total points to 18. Specific considerations are as follows: Applicable Individuals: Motor vehicle drivers holding a driver's license from the People's Republic of China, regardless of the permitted driving license type or whether they are commercial vehicle drivers, can participate in point reduction. They must participate in corresponding road traffic safety laws, regulations, and related knowledge learning and examinations according to their highest permitted driving license type. Specific Rules: Motor vehicle drivers participating in online road traffic laws, regulations, and related content learning must study continuously for 5 minutes each time, accumulating 30 minutes of study within 3 days. They can then register for an examination within 7 days. Passing the examination will reduce 1 point. Drivers can also attend on-site learning, with each session lasting no less than 1 hour. After completing the required study hours, they can apply for an examination. Passing the examination will reduce 2 points. Drivers can also participate in offline safety public welfare activities, with each session lasting 1 hour, reducing 1 point per session. Accumulating 30 minutes of study within 3 days, with each study session lasting no less than 5 minutes, and passing the examination can reduce 1 point. The maximum point reduction in one scoring cycle is 6 points. Non-acceptance Situations: The following situations will not be accepted: In the previous scoring cycle, the driver had two or more instances of full-point penalties. Within a 3-point cycle, the driver was involved in hit-and-run accidents, drunk driving, or the use of forged or altered documents or license plates. The driver's license is in the probation period or has not been reviewed on time. The driver has unprocessed traffic violation records. The driver has a vehicle with an expired safety technical inspection or one that has not been deregistered as required. The driver has already reduced the maximum of 6 points in the current cycle.

How to Set Up Vehicle Touch Alarm?

Adjust the alarm sensitivity to the highest level. In this case, the vehicle will sound an alarm whenever it is touched. Below is relevant information about vehicle alarms: 1. Definition: A motor vehicle alarm refers to a device that emits warning signals, used for issuing and canceling alerts. If the vehicle originally lacks this function, you can have it modified at an authorized service center or repair shop. After modification, the alarm function will work normally. During modification, try to avoid altering the original wiring of the vehicle. 2. Precautions: In daily use, it is highly discouraged to set the alarm this way because even wind blowing past the vehicle could trigger the alarm.

What is an Automotive Filter Element?

The oil filter element, also known as the oil filter, functions to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil, thereby protecting the engine. Relevant information about the air filter is as follows: 1. Classification of air filters: Based on the filtration principle, air filters can be divided into several types including filtration type, centrifugal type, oil bath type, and composite type. 2. Regular cleaning of the air filter is necessary: After prolonged operation, the filter element accumulates a certain amount of impurities, leading to increased pressure and reduced flow rate, at which point timely cleaning is required.

Why Do Flooded Cars Have Their Trunks Opened?

The reason why the trunk of a flooded car is opened is due to air pressure; at a certain pressure, the trunk will automatically open. Below are specific methods to determine if a car has been flooded: Odor: When sitting in the driver's seat, there will be a rotten smell of mud. No matter how much a water-damaged car is cleaned, some traces of this mud odor will remain. Copper Wire Oxidation: There will be oxidized copper wires on the wiring and connectors. In severely flooded cars, even after treatment, it's difficult to completely remove moisture from the engine wiring and transmission sensor connectors. Over time, the copper wires on these components will react with air and moisture, forming green copper rust.

Will the fuel tank of a flooded car take in water?

The fuel tank will not take in water. The fuel tank has excellent sealing and a certain degree of pressure resistance. Here is additional information: Vehicle wading: Vehicle wading refers to driving through low-lying, waterlogged areas, typically occurring during rainy weather when inadequate drainage leads to water accumulation in low-lying road sections. Stall handling: If a car stalls in water, the main cause is usually water entering the exhaust pipe, though in some cases, electrical damage may also occur. Once the car stalls, never attempt to restart the engine, as this may cause water to enter the intake manifold and damage the valves, potentially leading to severe engine failure.
