The method to address the illuminated exhaust emission control system indicator light is to clean the carbon deposits from the throttle and fuel injector. The maintenance methods for the engine include: 1. Use qualified engine oil; 2. Use qualified coolant and antifreeze; 3. Regularly clean the radiator scale; 4. Regularly clean engine carbon deposits; 5. Regularly replace the three filters of the car; 6. Maintain reasonable engine speed. The function of the engine is to convert the heat energy of gasoline or diesel into mechanical energy by expanding the gas after combustion in a sealed cylinder, thereby pushing the piston to perform work. The engine consists of: the engine block, the crankshaft and connecting rod mechanism, the valve train and intake/exhaust system, the fuel supply system and governor, the starting device, the cooling system, and the lubrication system.

What are the symbols for China's emission standards?

China's vehicle emission standards are denoted as China I, China II, China III, China IV, China V, and China VI. The purpose of these emission standards is to implement environmental protection laws, reduce and prevent vehicle exhaust pollution, protect the ecological environment, and ensure human health. Below is a detailed introduction to China's vehicle emission standards: China I Emission Standard: In the early 1980s, China issued a series of motor vehicle exhaust pollution control emission standards, including the "Idle Emission Standard for Gasoline Vehicles," "Free Acceleration Smoke Emission Standard for Diesel Vehicles," "Full-Load Smoke Emission Standard for Automotive Diesel Engines," and their measurement standards. This marked the gradual establishment of China's vehicle emission standards. The China I standard was fully implemented nationwide on July 1, 2001. China II Emission Standard: By this stage, China had developed a relatively complete vehicle exhaust emission standard and testing system. Beijing was the first to implement the China II emission standard. The requirements for various pollutant emissions were further tightened, and the standard was implemented nationwide by July 1, 2004. China III Emission Standard: On December 30, 2005, Beijing began implementing the China III emission standard. It was also during this time that OBD devices started to be widely used. The specific implementation dates were: July 1, 2009, for light-duty diesel vehicles; July 1, 2010, for heavy-duty gasoline vehicles; July 1, 2008, for heavy-duty gas vehicles; and July 1, 2008, for heavy-duty diesel vehicles. China IV Emission Standard: On January 1, 2008, China IV fuel was introduced in Beijing, followed by the implementation of the China IV standard in multiple cities such as Beijing, Shanghai, and Guangzhou. The nationwide implementation dates were: July 1, 2013, for light-duty diesel vehicles; July 1, 2013, for heavy-duty gasoline vehicles; January 1, 2011, for heavy-duty gas vehicles; and July 1, 2013, for heavy-duty diesel vehicles. China V Emission Standard: The China V emission standard was fully implemented nationwide on July 1, 2017. Compared to China IV, it reduced nitrogen oxide emissions by 25% and introduced stricter PM emission limits. China VI Emission Standard: The "China VI" standard is an upgrade of the China V standard. Compared to "China V," "China VI" imposes stricter limits on pollutant emissions, making it one of the most stringent standards globally. Specifically, "China VI" reduces carbon monoxide emissions from gasoline vehicles by 50%, total hydrocarbon and non-methane hydrocarbon emission limits by 50%, and tightens nitrogen oxide emission limits by 42%.

What is the fuel tank capacity of the 2019 Sportage?

The fuel tank capacity of the 2019 Sportage is 58L. This data is officially released, and owners of the 2019 Sportage can also check it on the vehicle's configuration sheet. The 2019 Sportage comes in two variants with different engine displacements. The model equipped with a 1.4T engine uses 92-octane fuel, has an NEDC combined fuel consumption of 6.3L/100km, and can travel up to 920km on a full tank. The model equipped with a 2.0L naturally aspirated engine also uses 92-octane fuel, has an NEDC combined fuel consumption of 6.9L/100km, and can travel up to 840km on a full tank. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is usually done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity. In addition, the following factors can affect a vehicle's fuel consumption: Vehicle weight: There is a direct correlation between vehicle weight and fuel consumption. A 10% reduction in weight can lead to a corresponding reduction in fuel consumption. Vehicle aerodynamics: A lower drag coefficient results in significantly reduced fuel consumption, while a higher drag coefficient increases fuel consumption proportionally. Tire pressure: Low tire pressure increases friction and adhesion, leading to higher fuel consumption. Driving habits: Aggressive acceleration, frequent braking, and rapid starts can significantly increase fuel consumption. Wind direction: Driving with a tailwind reduces fuel consumption, while driving against a headwind increases engine workload and fuel consumption. Road conditions: Driving on flat roads results in lower fuel consumption, while driving on uneven or steep roads increases fuel consumption. Use of additional electronic devices: Operating extra equipment like the air conditioning while driving increases fuel consumption.

What is the starting current of a car in amperes?

During startup, the maximum current can exceed 300 amps, and if the engine has more cylinders, the current will be even higher. Engines with more cylinders are equipped with higher-power starters; otherwise, the engine cannot start smoothly. Battery in the starting system: The car's starting system also includes the battery, which provides energy to the starter. Without the battery, the starter cannot operate. The battery is a very important component and is also a wear part that needs to be replaced regularly. As the number of charge and discharge cycles increases, the battery's storage capacity will decrease, so car owners need to replace their car's battery periodically.
