Why is the Leiling's engine so loud?

What does it mean when the engine exhaust fault light is on?

Engine exhaust fault light is on for the following reasons: Fuel pump failure: If the fault light comes on and the vehicle cannot start after stalling, this is usually due to a fuel pump or ignition system failure. It requires replacement of new fuel pump, ignition coils, spark plugs, and other components. Continuing to drive may cause severe shaking, lack of acceleration, and other symptoms. Addressing this promptly not only prevents further engine damage but also ensures the safety of the driver and passengers. Excessive carbon buildup: The engine exhaust system fault light may illuminate due to excessive carbon deposits in the throttle body or inside the engine, causing an imbalance in the air-fuel mixture. When the engine control unit detects signals affecting emission requirements, the fault light will activate. The vehicle then requires carbon cleaning or throttle body replacement.

What is the difference between four-valve and two-valve engines?

The differences between four-valve and two-valve engines are as follows: 1. Four-valve engines have larger intake and exhaust cross-sectional areas: Compared to two-valve engines, four-valve engines can increase the intake area by approximately 30% and the exhaust area by about 50%. 2. Additionally, four-valve engines have improved charging efficiency: The two intake valves create more suitable air movement, thereby enhancing mixture formation and reducing CO and HC emissions. Due to the shortened combustion duration, the formation of NOx is reduced. Lighter valve mass allows for higher engine speeds. The adoption of multiple valves increases charging efficiency and combustion speed, resulting in engine power output increasing by up to 45% and improved power per liter.

What does automatic dual-clutch mean?

Automatic dual-clutch refers to a dual-clutch transmission (DCT), which combines the flexibility of a manual transmission with the comfort of an automatic transmission while providing uninterrupted power output. Dual-clutch: A dual-clutch transmission differs from conventional automatic transmission systems. Based on manual transmissions yet belonging to the automatic transmission category, it is a transmission mechanism capable of both transmitting and cutting off power. Its primary functions are ensuring smooth vehicle starts, reducing impact loads on transmission gears during gear shifts, and preventing drivetrain overload. Disadvantages of traditional manual transmissions: Traditional manual transmissions use a single clutch. During gear shifts, the driver must depress the clutch pedal to engage different gears, resulting in power interruption during shifting and intermittent power delivery.

How to Disable the Santana's Automatic Locking Feature?

Santana's automatic locking feature cannot be disabled as it is a factory setting that activates when the vehicle speed reaches 20 mph. Below is relevant information: 1. The automatic speed-sensing lock is an electronic device. 2. When the vehicle reaches a preset speed (typically set by the manufacturer, usually between 10-20 km/h), the lock button automatically engages to prevent accidental door opening. This is the most common method of automatic locking used in many vehicle models. There are other methods of automatic locking as well. For instance, when the transmission is shifted into D (Drive) gear, the lock button automatically engages to prevent accidental door opening. Some Chevrolet and Buick models use this locking method.

How Often Should You Inflate Your Car Tires?

Generally, you should top up your tire pressure every 1-2 months. Equip yourself with an electric air pump and tire pressure gauge: Every car owner should keep an electric air pump and tire pressure gauge in their vehicle. Many car detailing shops have outdated pressure gauges that often show significant errors. For safety reasons, it's advisable to carry a high-quality portable tire pressure gauge. Under normal circumstances, if there are no obvious abnormalities on the tire sidewalls, checking the tire pressure weekly is sufficient. Monitor tire pressure: Many people only visit car washes to inflate their tires when they notice them looking flat. However, by this point, the tires may already be severely underinflated, with the sidewalls lacking proper support. This not only increases fuel consumption but also causes greater body roll during turns and increases the risk of overheating and blowouts during high-speed driving.
