Methods to check car RPM: Look at the tachometer on the dashboard, which is usually marked with a basic unit of 1000 revolutions per minute. Multiply the pointer reading directly by the unit to get the RPM. If it's a digital dashboard, you can switch to the tachometer mode and read the value directly. The level of car RPM relates to the number of work cycles per unit time or the effective power of the engine, meaning the engine's effective power varies with different RPMs. Therefore, when stating the effective power of the engine, the corresponding RPM must also be specified. The effective power and its corresponding RPM specified on the engine's product label are referred to as the rated power and rated RPM, respectively.

What Causes the Car Starter to Not Respond When Igniting?

Possible reasons for this issue include: 1. Power supply and transmission failure, or starter relay malfunction. During inspection, the first step is always to check the battery condition. You can turn on the headlights to observe their brightness. If the lights appear dim, it may indicate excessive battery discharge, loose connections, or poor contact. 2. If the battery is in good condition, check for relay faults: examine whether the relay coil has burnt windings or open circuits. Check if the relay contacts are severely burnt or fail to close. If none of these issues exist, proceed to inspect the starter motor. 3. Check whether the electromagnetic switch contact disc can properly connect both contacts, including verifying if the contact heights are uniform and inspecting for any burning. Examine whether the commutator is burnt, affecting poor contact with the brushes. Check if the brushes are grounded or have open circuits with the field windings. Inspect whether the field windings and armature windings themselves have open circuits, short circuits, or grounding issues. Finally, check if the armature shaft is bent or "eccentric."

Why does the AC turn on automatically when defogging is activated?

When the defogging function is activated in a car, the air conditioning also turns on simultaneously. This is designed to accelerate the removal of fog by utilizing the principle of the refrigeration evaporator condensing moisture inside the vehicle. Fogging on the front windshield typically occurs during winter or rainy days. Depending on the season, you can choose between hot or cold air: 1. Using cold air: This method is generally suitable for rainy days in summer. The operation is straightforward—simply turn on the cold air, adjust the vents to the front windshield, and activate the external circulation. This approach quickly and effectively eliminates fogging on the front window. 2. Using hot air: Turn on the hot air, select the front windshield as the vent outlet, and turn off the internal circulation. This method addresses the root cause of fogging but takes longer, making it less suitable for use while driving. However, over time, the fog will gradually dissipate, and the interior will become warm and comfortable, making it ideal for cold winter weather.

What is the highway fuel consumption of the Magotan?

The actual measured fuel consumption of the Magotan is around 9L/100km, based on user feedback. The official combined fuel consumption certified by the Ministry of Industry and Information Technology is 6.2L/100km, but actual fuel consumption may vary depending on the owner's driving conditions. The three main factors affecting fuel consumption are vehicle weight, car design, and driving conditions. There is a direct proportional relationship between vehicle weight and fuel consumption—it is said that a 10% reduction in weight can lead to a corresponding percentage decrease in fuel consumption. Relevant information about fuel consumption is as follows: 1. Introduction: Fuel consumption generally refers to constant-speed fuel consumption, which is the vehicle's fuel consumption per 100 kilometers obtained in standardized tests under constant-speed driving conditions. 2. Testing methods: The test can be conducted on the road or on a chassis dynamometer, and the fuel consumption per 100 kilometers is then calculated using the 'flow meter method' or 'carbon balance method.'
