What does the 4S in 4S store stand for?

4S store is a car franchise model centered around the "four-in-one" concept, encompassing vehicle sales, spare parts, after-sales service, and information feedback. Here is some additional information: 1. The 4S store model was introduced to China in 1998 by Guangzhou Honda as an imported concept, which was subsequently emulated by various automobile manufacturers. Due to its close production and sales relationship with manufacturers, along with advantages such as a superior shopping environment and strong brand awareness, it was widely imitated by domestic manufacturers. 2. It features a unified exterior appearance, standardized logos, consistent management standards, and exclusively deals with a single brand. It is a distinctive tangible market characterized by channel consistency and a unified cultural philosophy. 4S stores excel in enhancing the brand image of automobiles and the reputation of automobile manufacturers.

What is the actual fuel consumption of the Toyota RAV4?

The actual measured fuel consumption is 8.0L/100km, which is not much different from the 8.3L/100km displayed by the onboard computer. Such fuel consumption performance is considered quite good for a compact SUV in its class. Relevant details are as follows: 1. The Toyota RAV4 is a long-standing member in the domestic joint-venture urban SUV market. After being renamed as the RAV4 Rongfang, it has become more widely recognized. Unlike its tougher siblings like the "Land Cruiser" and "Prado", the RAV4 Rongfang is more oriented towards family use. 2. Comparison of highway fuel consumption between the old RAV4 2.0L and the current RAV4 2.0L. During a weekend trip of nearly 300km, 90% of the journey was on highways with a speed limit of 120km/h, and the remaining 10% was on congested urban ring roads, with an average speed of 90km/h. The final measured fuel consumption for the current RAV4 2.0L was 7.5L/100km, while the old RAV4 2.0L was 9.8L/100km, showing a very significant advantage in fuel economy for the new powertrain.

What is the function of a differential?

The function of a differential is to meet the requirement of different rotational speeds of the wheels on both sides when the car is turning. The differential mainly consists of left and right axle gears, two planetary gears, and a gear carrier. Its purpose is to allow the left and right wheels to roll at different speeds when the car is turning or driving on uneven road surfaces, ensuring that both driving wheels perform pure rolling motion. The classification of differentials is as follows: 1. Gear-type differential. Due to its structure, this differential distributes equal torque to the left and right wheels. This torque-equalizing characteristic meets the needs of normal driving on good road surfaces, but it severely affects the car's passability when driving on bad roads. 2. Anti-slip differential. When one driving wheel slips on a bad road, it can transfer torque to the driving wheel on a good road, utilizing the adhesion of this driving wheel to generate sufficient driving force. 3. Double-worm differential. Its characteristic is that two meshing worms are inclinedly installed in the rotor, with the ends of the two worm shafts connected to the output shafts on both sides. The connection can be made via gears or universal joints. The ring gear is installed on the rotor, and the whole assembly is fixed to the housing by bearings. The power source is input from the ring gear, and the output shafts on both sides deliver the power.

What is a Hybrid Electric Vehicle?

Broadly speaking, a hybrid electric vehicle refers to a vehicle whose propulsion system consists of two or more individual drive systems that can operate simultaneously. The vehicle's driving power is provided by a single drive system alone or jointly, depending on the actual driving conditions of the vehicle. More detailed information is as follows: 1. The commonly referred hybrid electric vehicle generally means a gasoline-electric hybrid vehicle, which uses a traditional internal combustion engine and an electric motor as power sources. Some engines are modified to use other alternative fuels, such as compressed natural gas, propane, and ethanol fuels. 2. As environmental protection measures become increasingly stringent worldwide, hybrid vehicles have become a focus of automotive research and development due to their energy-saving and low-emission characteristics, and they have already begun commercialization. 3. The electric power system used in hybrid electric vehicles includes highly efficient and enhanced electric motors, generators, and batteries. The batteries used include lead-acid batteries, nickel-metal hydride batteries, and lithium batteries. In the future, hydrogen fuel cells may also be used.

Under What Circumstances Should Fuel Injectors Be Cleaned?

The following situations require cleaning the fuel injectors: 1. When the fuel injectors are clogged, fuel injection is not smooth. 2. When there is carbon buildup and adhesive deposits in the injector gap, preventing the designed fuel injection volume or atomization effect, the fuel injectors need to be cleaned. Below is some relevant information about fuel injectors: 1. A fuel injector is essentially a normally closed valve. When the electromagnetic coil is energized, it generates suction, lifting the needle valve to open the injection hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist that facilitates complete combustion. 2. Generally, fuel injectors need to be cleaned when a car has traveled approximately 30,000 to 50,000 kilometers. However, the condition of the fuel injectors is also related to factors such as the car model and external environment, so this mileage is not always accurate.

How to Maintain a Car Engine?

Methods for maintaining a car engine: 1. Ensure good crankcase ventilation. Most gasoline engines are equipped with a PCV valve (Positive Crankcase Ventilation), but contaminants from blow-by gases can accumulate around the PCV valve, potentially clogging it. Therefore, it's essential to regularly clean the contaminants around the PCV valve. 2. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will degrade over time. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. 3. Periodically clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, nitrogen oxides, and other substances from the combustion chamber can enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from wear to form sludge. Hence, regular cleaning of the crankcase is necessary to keep the engine internals clean. 4. Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD-SF grade oil based on the additional equipment in the intake and exhaust systems and usage conditions. For diesel engines, choose CB-CD grade diesel oil based on mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. 5. Address engine radiator rust. Rust and scale can restrict coolant flow in the cooling system, reducing heat dissipation and causing engine overheating or even damage. Therefore, clean the radiator periodically to remove rust and scale. 6. Maintain the three filters. The three filters refer to the air filter, oil filter, and fuel filter. They filter air, oil, and fuel in the car engine, protecting the engine and improving its efficiency. 7. Regularly clean the fuel system to control carbon deposit formation, keeping the engine in optimal condition.
