Baojun 730 suddenly lights up the malfunction indicator lamp reasons: Carbon deposit issues: Poor gasoline quality can lead to incomplete combustion of the air-fuel mixture in the cylinder, causing the light to come on, and it also easily leads to carbon deposits. The presence of carbon deposits in the intake tract and on top of the pistons can result in poor atomization, leading to incomplete combustion and triggering the light. ECU temperature correction issues: During cold starts, especially when the temperature drops sharply, the light may come on due to the ECU's temperature correction. However, once the temperature stabilizes at a certain level without fluctuations, the situation will become relatively stable. Abnormal fuel supply pressure: Abnormal fuel supply pressure and faults in the intake pressure sensor can cause this issue. If the fuel pump's supply pressure is abnormal or the intake pressure sensor provides incorrect data or malfunctions, it can lead to engine shaking and insufficient power.

What does 94V mean on a tire?

94V on a tire indicates that the tire has a maximum load capacity of 670 kilograms and a maximum speed of 240 kilometers per hour. The following explains tire specifications and the functions of tires: Tire specifications: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the second number indicates the rim diameter in inches. For example, 165/70/R14 represents a radial tire with a width of 165 millimeters, an aspect ratio of 70, and a rim diameter of 14 inches. The tire model can generally be found on the tire sidewall. Functions of tires: Tires are circular elastic rubber products mounted on metal rims, designed for various vehicles or machinery. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain the vehicle's driving performance.

How to Identify China IV and China V Vehicles?

Check the vehicle's environmental protection label, which has clear markings on the back. Below are the differences between China IV and China V: Exhaust Emissions: Compared to previous standards, China V regulations reduce nitrogen oxide (NOx) emissions by 25% for light-duty vehicles and 43% for heavy-duty vehicles compared to China IV. Emission Standards: The China V emission standard reduces nitrogen oxide (NOx) emissions by 28% compared to China IV, and the combined hydrocarbon and nitrogen oxide (HC+NOx) index is lowered by 23%. For diesel vehicles, particulate matter (PM) concentration is reduced by 82%, and the new particulate number (PN) testing is specifically targeted at diesel vehicles, with PN standards only applicable to diesel vehicles.

What Does PHEV Mean?

Plug-in Hybrid Electric Vehicle (PHEV) refers to a vehicle that can be charged externally and operate in pure electric mode. Once the battery is depleted, it switches to hybrid mode (primarily powered by an internal combustion engine) while simultaneously recharging the battery. Hybrid vehicles are actually a broad category, which can be divided into three types: plug-in hybrid, conventional hybrid, and range-extended hybrid. Plug-in hybrid models offer a balance between power and fuel efficiency, enjoy preferential policies in most cities, and are not overly restricted in terms of range. Compared to pure electric vehicles, which generally have shorter ranges, most people would still prefer plug-in hybrid vehicles. Series Plug-in Hybrid: Series plug-in hybrid, also known as range-extended hybrid. The engine does not directly drive the vehicle; instead, it first drives a generator to produce electricity, which then powers the electric motor to drive the car. This results in a longer energy transfer chain and relatively lower overall efficiency. Representative models include the BMW i3 Range Extender. Parallel Plug-in Hybrid: In this type, both the engine and the electric motor can drive the vehicle. It offers multiple power transmission modes, better performance, a simpler structure, and is widely used, making it the mainstream technical route. Representative models include the BYD Tang DM.

What should be paid attention to when waxing a car?

First, wash the car thoroughly, preferably using a dedicated car wash solution to ensure it is completely clean. After rinsing the car, use a drying cloth to thoroughly dry the car, as water on the paint surface makes waxing difficult. Then, move the car to a shady area to prepare for waxing. Use a solid car wax with a dedicated round sponge to apply the wax evenly on the paint surface. It doesn't need to be too thick; a thin layer is sufficient. During the application process, you can use the sponge to draw circles evenly on the car body, creating a fish-scale effect with the wax on the paint surface.

What is the transmission model of the Binrui 1.4t?

The Binrui 1.4t is equipped with a 6-speed manual transmission and a CVT continuously variable transmission (simulating 8 gears), which is a transmission independently developed by Geely. The function of continuously variable transmission: Continuously variable transmission refers to a transmission system that can continuously obtain any transmission ratio within the transmission range. Through continuously variable transmission, the optimal matching between the transmission system and the engine operating conditions can be achieved. Common continuously variable transmissions include hydraulic mechanical continuously variable transmissions, metal belt continuously variable transmissions (VDT-CVT), and variable inclined plane continuously variable transmissions. The principle of continuously variable transmission: It uses two transmission wheels with variable diameters, with a transmission belt in the middle to transmit power. The two ends of the transmission belt are wound around a conical pulley, and the outer diameter of the pulley changes continuously based on oil pressure. The continuously variable transmission technology uses a transmission belt and variable-diameter driving and driven wheels to transmit power, enabling continuous changes in the transmission ratio, thereby achieving better matching between the transmission system and the engine operating conditions.

How Does a 4S Shop Compensate for a New Car's Transmission Replacement?

New car transmission replacement compensation information from 4S shops is as follows: Handling method: If there is a problem with the new car's transmission, the merchant is obligated to repair it. If the repair is unsuccessful, it should be replaced. Article 20 of Chapter 5 of the automobile three-guarantee policy stipulates that "if the vehicle has undergone two repairs for serious safety performance failures that have not been resolved or new serious safety performance failures have occurred," the car can be returned. Relevant regulations: The "Regulations on the Repair, Replacement, and Return of Household Automobile Products" issued by the General Administration of Quality Supervision, Inspection, and Quarantine, also known as the automobile three-guarantee regulations, have been implemented since October 1, 2013. It is recommended that consumers carefully understand the relevant details before purchasing a car.
