What is the principle of the BMW 730 fuel tank?

The principle of the BMW 730 fuel tank is to utilize the thermal energy generated by the engine during operation, adding a set of thermal circulation system between the engine, fuel tank, and water tank. Composition of the BMW 730 fuel tank: The original single fuel tank design is replaced by a combined fuel tank consisting of a main tank and an auxiliary tank. A water heater is installed at the bottom of the fuel tank to heat the main tank using the thermal energy generated by the engine. The fuel supply pipe of the main tank and the oil pipe of the auxiliary tank are connected to the engine oil circuit through an oil circuit conversion valve. The auxiliary tank is used when starting the car, and after driving 5-8 kilometers, the conversion valve is switched to cut the oil circuit into the main tank. Gasoline grades for the fuel tank: The main tank is filled with 0# oil, and the auxiliary tank is filled with -35# oil. The oil circuit of the main tank runs parallel to the heater pipeline, and a thermal insulation pipe is placed over the oil circuit pipeline and the heating pipeline to prevent the oil circuit from freezing in cold seasons.

What is the electric four-wheel drive method of the Wildlander?

The electric four-wheel drive method of the Wildlander is the DTC intelligent four-wheel drive system. Working principle of the DTC intelligent four-wheel drive system: Since the rear wheels have an open differential, the power distribution between the left and right wheels is controlled by the AIM (All-Wheel Drive Integrated Management System), which also utilizes the vehicle stability control system. In simple terms, it brakes the slipping wheel to transfer power to the other wheel. This is a relatively economical four-wheel drive system that can handle slippery road conditions and improve safety. Compared to the two-wheel drive version, it only increases fuel consumption by 0.4 liters per 100 kilometers. Modes of the DTC intelligent four-wheel drive system: Although the structure is relatively simple, the electronic system's logic is quite sophisticated. The 2.0L-CVT four-wheel drive luxury version offers three modes: snow, mud/sand, and loose gravel/soil. These can be understood as three levels of control to adjust the front-rear power distribution, wheel slip tolerance, engine output, etc., ensuring safe driving under different conditions.

Why does the electric vehicle show a green light but not charge?

The electric vehicle cannot charge because of a fault in the charger converter or a small battery in the battery pack. Charger converter fault: The charger converter or fuse is damaged, causing the electric vehicle to show a green light but not charge. The primary consideration is whether the charger has a fault, which usually manifests as a damaged converter or fuse. If the converter is damaged, the charger cannot convert and charge properly, resulting in the electric vehicle showing a green light but not charging. If the fuse is damaged, it directly results in no charging. The correct solution is to replace the converter or fuse, but if the issue persists, the only option is to replace the charger. Small battery fault in the battery pack: A fault in a small battery within the battery pack causes the electric vehicle to show a green light but not charge. The next consideration is whether the battery has a fault, which usually manifests as an open-circuit fault in one of the small batteries in the battery pack. In this case, when attempting to charge the electric vehicle, the charger will continuously show a green light without charging. The correct solution is to have a technician use a multimeter to check each battery for faults, identify the faulty battery, and determine if it can be repaired. If repair is not possible, the only option is to replace the battery.

What does 'Hill Start Assist Unavailable' mean?

Hill Start Assist Unavailable means that the current road environment is not suitable for using the hill start assist function. Introduction to Hill Start Assist Function: Derived from the ESP system, its function is to allow the vehicle to start on a slope without using the handbrake. During the gap when the foot moves from the brake pedal to the throttle, the hill start assist system maintains braking for 2 seconds, making it easy to switch from the brake pedal to the throttle pedal, preventing the vehicle from rolling back. It also prevents the driver from feeling flustered. Conditions for Hill Start Assist System Activation: The gear lever is in any position other than P (for automatic transmission models); the throttle pedal is not pressed; the vehicle is stationary; the parking brake (handbrake or foot brake) is not engaged.

These small insects specifically suck on tender branches and leaves and then excrete sticky liquid, which is also particularly difficult to clean. Purpose of removing tree sap: It can protect your beloved car from heat and rain, naturally shielding it from tree sap, and also prevent the paint from discoloring due to prolonged exposure to the sun.
