Haval H7 burns oil because the engine's lubricating oil film tends to break when the engine operates at extremely high speeds, leading to poor lubrication and dry friction in rotating parts. The solution is to ensure that the oil is filled according to specifications. If the oil level exceeds the midpoint, the excess oil should be extracted by the mechanic. Additionally, the oil level should be checked the next day before driving. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the "blood" of a car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new characteristics. Additives are an essential part of the lubricant.

What is the fuel tank capacity of the 2021 Bora?

The fuel tank capacity of the 2021 Bora is 50 liters, and it requires 92-octane or higher unleaded gasoline. The Bora is a compact car under FAW-Volkswagen. The 2018 Bora had a fuel tank capacity of 55 liters, while the 2019 and 2020 models both have a 50-liter fuel tank, also requiring 92-octane or higher unleaded gasoline. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with "E" and "F". When the needle is close to "E," it indicates low fuel, and when it approaches "F," it means the tank is nearly full. Maintenance tips for the fuel tank include: Draining accumulated water and sediment from the tank, and checking for leaks at fuel line connections and switches. For fuel tank caps equipped with air and vapor valves, ensure the vent holes are clear. The fuel filler inlet screen should be intact to prevent debris from entering the tank and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel spillage while driving.

Where is the OBD interface of the Bora located?

Volkswagen Bora's OBD interface is located next to the battery in the engine compartment. Here is the relevant content introduction: 1. OBD: OBD refers to the On-Board Diagnostics system. It is divided into two parts. OBD1 in China only required compliance with Euro 3 emission standards before July 2010. After that, all vehicles were required to have OBD2 functionality, which added alarm functions for excessive pollutant emissions, including alerts for misfire rates causing excessive emissions, alerts for oxygen sensor degradation leading to excessive emissions, and alerts for catalytic converter degradation causing excessive emissions. 2. Function: It locates and describes faults in components, facilitating repairs.

What is the fuel tank capacity of the Geely Binyue?

2021 Geely Binyue has a total of 6 models, all of which have a fuel tank capacity of 45 liters. The entire series is equipped with either a 1.4-liter or 1.5-liter turbocharged engine, and comes with three types of transmissions: a 6-speed manual transmission (MT), a 6-speed wet dual-clutch transmission (DCT), or a 7-speed wet dual-clutch transmission (DCT). All models feature front-wheel drive. In comparison to similar vehicles, the Song has a fuel tank capacity of 63 liters, the Haval M6 has 55 liters, and the Changan CS75 has 58 liters. If owners want to check the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates low fuel, and when it is near F, it means the fuel level is sufficient. Maintenance for the fuel tank includes: Draining accumulated water and sediment from the tank, and checking for leaks at fuel pipe connections and switches. For fuel tank caps equipped with air valves and vapor valves, ensure the vent holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank and clogging the fuel lines during refueling. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel from spilling out while driving.

How Long Does a Volkswagen Dry Dual Clutch Last?

The lifespan of a dry dual clutch is about ten years, and generally, the clutch plates need to be replaced after approximately ten years of use. Strictly speaking, there is no precise, standard, or uniform answer to this question because the number of years a dry dual clutch can last is influenced by too many objective factors. For example, daily driving conditions and driving habits can significantly impact the lifespan of a dry dual clutch. Methods to extend the clutch's lifespan include using the clutch decisively. The clutch is primarily used for gear shifting and starting/stopping the vehicle. When shifting gears, it should be done promptly and decisively without hesitation. Especially in low gears, releasing the clutch should be done quickly at first and then slowly to avoid excessive impact on the clutch, which is detrimental to its lifespan. The functions of the clutch include gradually increasing the driving force of the car to ensure a smooth start; temporarily separating the engine and transmission for gear shifting; preventing overload in the transmission system; and reducing torsional vibration shocks from the engine to extend the lifespan of the transmission gears. Symptoms of a faulty clutch include clutch slipping: when starting the car in low gear, the car fails to start or has difficulty starting after releasing the clutch pedal; incomplete clutch disengagement: even when the clutch pedal is fully depressed, the power between the driving and driven plates of the clutch cannot be completely cut off, leading to difficulty in shifting gears, gear grinding, inability to stop, or clutch overheating; clutch shuddering; and abnormal clutch noises.
