What Happens When the Idle Speed is Unstable?

Unstable idle speed in a car is mainly manifested by the fluctuation of the tachometer needle up and down, pointing unstably, moving up and down, often accompanied by idle vibration. Unstable idle speed can be considered one of the most common engine faults, which can range from minor to severe. Under normal circumstances, the engine idle speed is fixed, with the specific level depending on the tuning of the particular model. Generally, a higher idle speed leads to relatively higher fuel consumption, but an idle speed that is too low can cause the engine to vibrate or even stall. Below is relevant information about unstable idle speed: 1. Oil residue and carbon deposits in the throttle body, dirty intake manifold: A clogged intake manifold can cause idle pull, while carbon deposits or oil in the throttle body are the most common causes of unstable idle speed. Carbon deposits in the throttle body can affect its opening, influencing the intake air volume, causing the engine speed to fluctuate erratically after a cold start, being very unstable and accompanied by strong vibrations. 2. Weak sparks from faulty spark plugs: Spark plugs can also accumulate carbon deposits, which can be cleaned to restore their activity, but some spark plugs may be nearing the end of their lifespan, leading to decreased performance. Weak sparks from spark plugs in individual cylinders can affect the car's performance. It is known that spark plug faults can cause the car to exhibit "misfire" symptoms, but minor faults in spark plugs of individual cylinders can lead to unstable idle speed symptoms.

What is the appropriate tire pressure for front car tires?

According to the regulations and requirements of the international GBT2978-2008 standard, the standard tire pressure for tires is 2.4-2.5 bar. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Generally, an alarm will sound if the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure reset is not performed in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to turn on. In this case, simply perform a tire pressure reset. Tire pressure sensor damage: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation valve. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to turn on. For sensor damage issues, only a new replacement part can be installed.

Should Transmission Fluid Be Replaced?

Transmission fluid needs to be replaced periodically. More information about transmission fluid is as follows: 1. The main function of transmission fluid is to keep the shifting system clean, as well as lubricate and prolong the lifespan of the transmission components. 2. The replacement interval for transmission fluid is longer compared to other fluids, and some vehicle models feature maintenance-free transmission fluid. 3. Generally, the automatic transmission fluid (ATF) in vehicles should be replaced every two years or every 40,000 kilometers, but this varies depending on the vehicle model, as different models have different requirements.

What is the fuel tank capacity of the Geely King Kong?

The fuel tank capacity of the Geely King Kong is 45 liters. A fuel tank is a container for storing fuel, used in aircraft or automobiles, and is a specialized container in hydraulic systems for storing hydraulic oil or fluid. Fuel tanks can be divided into two types: open tanks and closed tanks. To maintain oil cleanliness, the tank should have a sealed cover around its perimeter, equipped with an air filter. The bottom of the tank should be at least 150mm above the ground. Taking the 2019 New King Kong 1.5L Manual Base model as an example: it is a compact 4-door, 5-seater sedan, equipped with a 5-speed manual transmission. Its dimensions are 4342mm in length, 1692mm in width, and 1435mm in height, with a wheelbase of 2502mm, and a top speed of 165 kilometers per hour.

Is the Geely Boyue Engine Domestically Produced?

Geely Boyue's engine is domestically produced and independently developed by Geely. The Geely Boyue offers consumers a choice between a 1.8TD engine and a 2.0L naturally aspirated engine. The 1.8TD engine equipped in the model is an upgraded high-power version based on the Borui 1.8TD, which was awarded the 'China's Top 10 Engines in 2015.' It delivers strong power and excellent performance. The 2.0L naturally aspirated engine, model JLD—4G20, is part of Geely's GeTec high-efficiency green energy-saving engine series. The entire GeTec series features an all-aluminum cylinder block, achieving engine lightweighting, while the aluminum cylinder block also offers better recyclability compared to cast iron blocks. Additionally, GeTec engines incorporate a dual-balance shaft design, chain-driven variable valve timing technology, an all-plastic intake manifold, and a water-jacket cooling system. Through these technological advancements, the GeTec series engines achieve the goals of energy efficiency and environmental protection.
