What are the reasons for the inability to adjust motorcycle idle speed?

The reason why the motorcycle idle speed cannot be adjusted is that the idle jet is partially blocked, resulting in a lean fuel supply at idle. Solutions for idle adjustment failure: The carburetor should be cleaned; If the gasket or rubber ring connecting the carburetor and the engine intake pipe is damaged, air leakage will occur, allowing additional air to enter the engine, causing a lean fuel supply at idle and resulting in unstable idle speed. Replace the connecting gasket or rubber ring. If the connecting bolts between the carburetor and the engine intake pipe are loose, air leakage will also occur. Tighten them to resolve the issue. Precautions for idle speed adjustment: Adjust the throttle adjustment screw and idle adjustment screw. If the idle speed cannot be adjusted, it indicates a carburetor malfunction. Remove the carburetor, use a 0.2mm wire to clear all holes, and blow out all channels and jets with a high-pressure gun. If there is still no idle speed, check whether the intake manifold bolts are tightened; if loose, tighten them. If there is still no idle speed, it means the fuel level in the carburetor float chamber is too low and should be adjusted. If the above methods do not work, check whether the cylinder pressure is appropriate (greater than 600 kPa), and inspect all sealing parts in sequence, such as valves, pistons, etc., and resolve any issues. Generally, the idle speed is pre-adjusted when the motorcycle leaves the factory. If idle speed problems occur, first follow the manufacturer's instructions for repeated debugging.

How Far Can You Drive with a Tire Pressure Warning?

You should not drive when the tire pressure warning is activated. The purpose of the tire pressure warning is to automatically alert and display the tire status when there is air leakage, excessive or insufficient tire pressure, or high temperature, ensuring driving safety. Abnormal tire pressure can be caused by the following reasons: Abnormal tire pressure: Generally, the warning will activate if the pressure is below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to display the previously recorded data, causing the tire pressure warning light to illuminate. Simply reset the tire pressure monitoring system to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors the tire pressure. If the sensor is damaged during driving (e.g., by impact), the tire pressure warning light may also turn on. In case of sensor damage, the only solution is to replace it with a new part.

What engines do domestic cars use?

Domestic cars use the following types of engines: Chery Engine: Chery Automobile is the only domestic brand in China that independently develops all three major components (engine, transmission, and chassis). Recently, it launched the most powerful 1.6T turbocharged engine in its history, which can run for 300,000 kilometers over ten years with a lifetime warranty. It is exceptionally robust, with the Chery Tiggo 8 being a representative model. Changan Automobile Engine: Changan's Blue Core engine has been rated as the best-selling engine among domestic cars. As one of China's top four automotive groups, Changan possesses strong vehicle manufacturing technology. Models like the Changan CS75 Plus 2.0T, Changan CS35 Plus 1.4T, and Eado 1.4T all use the Blue Core engine. This engine meets the China VI emission standards, delivering a maximum power of 116 kW and a maximum torque of 260 Nm. It reaches peak torque at just over 1,400 rpm, demonstrating performance on par with joint-venture engines. It also offers excellent fuel economy, along with well-controlled power and noise levels. Geely Automobile Engine: Although Geely started relatively late, its engines are of high quality and performance, especially after acquiring the Volvo brand, which significantly enhanced its vehicle manufacturing capabilities. Many of its models feature outstanding engines. The Geely Emgrand GS uses a self-developed 1.3T engine and a 1.8L engine, both of which are technologically mature and stable in performance. These engines cater to consumers seeking family-friendly and economical options. The 1.3T turbocharged engine delivers a maximum power of 95 kW at 5,500 rpm and a peak torque of 158 Nm between 2,000–4,500 rpm, equivalent to the power output of a 1.8L–2.0L naturally aspirated engine. Additionally, it performs well in terms of fuel efficiency and noise reduction. Great Wall Motors Engine: When it comes to the Great Wall brand, many veteran drivers might associate it with high fuel consumption, but this is an outdated notion. Current models like the Haval H6 and Haval F7 feature a 2.0T engine with a maximum horsepower of 224, excelling in both performance and fuel economy.
