Adding substances such as sugar, salt, sand, and detergent to a diesel fuel tank can cause it to quickly become scrapped. Under normal circumstances, a diesel fuel tank will gradually age and eventually become scrapped over time with increased usage frequency. Firstly, diesel engines are compression-ignition types, where the fuel is ignited by the heat generated from the compression of air inside the cylinder. In other words, compressing the air raises its temperature, and when the temperature of the compressed air exceeds the ignition point of diesel, the diesel will combust. Diesel engines also have a relatively high compression ratio, generally above 14. Diesel-powered vehicles often travel on highways, running for extended periods with high engine temperatures and pressures, leading to the production of more soot and carbon deposits inside the cylinders. Engine oil is also prone to oxidation, forming sludge. Therefore, diesel engine oil is required to have excellent high-temperature detergency. If impurities or unknown solvents are added to the diesel fuel tank, they can damage the smoothness and clearance of various machine components. Over time, this will worsen the engine combustion process, leading to the diesel fuel tank being scrapped.

What does ESC mean on a car?

ESC on a car refers to the Electronic Stability Control system. When the ESC is activated, pressing and holding the ESC button can deactivate the Electronic Stability Control system. The Vehicle Stability Control system is an active safety system developed by Toyota, which significantly enhances vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the system can quickly detect and take appropriate braking actions, such as individually controlling each wheel while reducing engine output to maintain vehicle stability. The Electronic Stability Control system is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functionalities. It incorporates additional sensors like the yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor during vehicle steering. Through the ECU, it controls the driving and braking forces of the front, rear, left, and right wheels to ensure lateral stability during driving.

Does moving the front wheels back by 1 cm have any impact?

Moving the front wheels back by 1 cm does have an impact. It directly affects the vehicle's wheel alignment. The rearward movement can accelerate tire wear and reduce stability, so repairs are recommended. Below are the specific details about wheel alignment: 1. Purpose: Wheel alignment involves inspecting and correcting the vehicle's driving trajectory, including adjustments to the suspension, chassis, and components. 2. Function: Wheel alignment is responsible for adjusting the data of all four wheels. 3. Definition: Front wheel alignment includes four aspects: caster angle, kingpin inclination angle, camber angle, and toe-in. Rear wheel alignment includes camber angle and individual rear wheel toe-in. Collectively, front and rear wheel alignment is referred to as wheel alignment, commonly known as four-wheel alignment.

What is the fuel consumption of the BYD Han?

The BYD Han has a fuel consumption of 5.9 liters per 100 kilometers. The BYD Han is a plug-in hybrid vehicle, equipped with a 2.0-liter turbocharged four-cylinder engine. The BYD Han is a mid-to-large-sized sedan under the BYD brand. Reasons for increased fuel consumption: Fluctuations in fuel consumption due to temperature changes, prolonged lack of vehicle maintenance, and the need to replace spark plugs, among others. Prolonged lack of vehicle maintenance: Dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, which in turn increases fuel consumption.
