What Could Be the Reason for Feeling Less Power After Changing Spark Plugs?

The reasons for feeling less power after changing spark plugs may include: The spark plugs were not tightened properly; The replaced spark plugs are of the wrong model; There is an issue with the ignition coil. Effects of damaged spark plugs: If the spark plugs are damaged, it can directly cause various problems such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant issue is difficulty in ignition, affecting the normal use of the vehicle. Severe erosion of the spark plugs, scarring at the top, damage, or melting and erosion of the electrodes indicate that the spark plugs are damaged and should be replaced. How to determine if spark plugs are damaged: Remove the spark plugs and observe their appearance to assess their condition. Normal spark plugs have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plugs are covered in oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, showing signs such as scarring, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or that the mixture is too rich, with oil seeping up.

What is the typical mileage for a car's break-in period?

The break-in period for a car is generally between 1,000 to 3,000 kilometers. During this period, it is essential for the owner to properly control the vehicle's speed, avoiding sudden braking and rapid acceleration. Additionally, preheating the engine before starting the car ensures proper lubrication, helping to prevent unnecessary malfunctions that could affect normal usage. It is normal for new cars to experience minor issues during the break-in period, as components have not yet fully adapted to each other. Poor driving habits can further increase the likelihood of such issues.

Can a Lost Car Key Be Tracked?

Lost car keys cannot be tracked, but once a new remote key is paired, the original key will automatically become invalid. Here are some details about remote keys: 1. Function: A remote key utilizes the wireless remote control feature of the central locking system, allowing users to lock or unlock the car from a distance without inserting the key into the lock. 2. Working Principle: The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the locking or unlocking action. This system mainly consists of a transmitter and a receiver.

What are the common issues with the Blue Whale engine?

The common issues with the Blue Whale engine include noticeable engine noise entering the cabin at high RPMs and a relatively stiff chassis. The 1.4T variant of the Blue Whale engine delivers a maximum horsepower of 158 HP and a peak torque of 260 N·m, which offers competitive performance among engines of the same displacement. Below is additional information: The Blue Whale NE1.4T high-pressure direct injection engine features a fully variable displacement oil pump + controllable PCJ, enabling precise pressure regulation based on different engine load conditions and on-demand supply. This achieves closed-loop pressure control, reducing power consumption by approximately 3%.

What are the common causes of car battery leakage?

Car battery leakage is generally caused by the following reasons: 1. Battery failure: Short circuit or oxidation shedding of battery plates leads to self-discharge and power loss, which is caused by internal battery discharge. This reason is an important indicator related to the quality of the battery itself. 2. Circuit grounding: Electronic components such as car electrical appliances, wiring harnesses, sensors, controllers, and actuators, as well as circuit grounding, cause battery leakage and power loss. This reason is called external battery discharge, and this kind of leakage is a latent circuit fault, which must be investigated as a leakage fault.

Can a Private Car Run Continuously for 24 Hours?

Private cars can run continuously for 24 hours, but doing so may cause certain damage to the engine. Here are some relevant details about car engines: 1. Optimal State: The general RPM range is between 1000~3500, with the maximum torque output occurring around 3000 RPM, after which it inversely correlates with RPM. 2. Impact of RPM: The engine's RPM affects the number of work cycles per unit time or the effective power output, meaning the engine's effective power varies with different RPM levels. Therefore, when specifying the engine's effective power, the corresponding RPM must also be indicated.
