What is the difference between BMW 730 and BMW 740?

Does the Camry coolant need to be replaced at 160,000 kilometers?

Camry coolant needs to be replaced at 160,000 kilometers, and then every 80,000 kilometers thereafter. The method for replacing Camry coolant is as follows: Fill the reservoir, start the car, wait until the water temperature is normal and the electric fan starts working, then check the coolant level in the reservoir. If it is low, add more coolant, and check it again in the following days. The Camry is a mid-size sedan under Toyota, with body dimensions of 4885mm in length, 1840mm in width, and 1445mm in height, and a wheelbase of 2825mm. The new Camry uses two engines, one is a 2.0-liter naturally aspirated engine, and the other is a 2.5-liter naturally aspirated engine. These engines are paired with a CVT transmission and an 8AT transmission, respectively.

What is the suitable engine oil for Baojun 730?

Baojun 730 can use either 5w30 or 0w30 engine oil. Here is some extended information about engine oil: 1. Engine oil is something every car owner will come into contact with during vehicle use. It is referred to as the 'blood' of the engine, as the engine cannot operate normally without it. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. 2. When the engine is running, the oil forms a thin film on the surfaces of various components inside the engine, preventing direct contact and friction between them. 3. If engine components directly contact and rub against each other, it will accelerate engine wear and cause the engine to overheat. Continuous operation in an overheated state can lead to severe engine damage. Over time, the performance of engine oil degrades, so it needs to be replaced regularly.

What is the energy source used by new energy vehicles?

New energy vehicles primarily use energy sources including fuel cells, hybrid power, hydrogen energy, etc. New energy vehicles refer to all other types of vehicles besides those powered by gasoline or diesel engines, as well as solar energy, among others. More related information is as follows: 1. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. 2. From the perspective of global new energy vehicle development, their power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and supercapacitors, with supercapacitors mostly appearing in the form of auxiliary power sources. The main reason is that these battery technologies are not yet fully mature or have obvious shortcomings, resulting in significant gaps compared to traditional vehicles in terms of cost, power, and range, which is also an important factor restricting the development of new energy vehicles.

What Components Make Up an Automobile System?

The following are the components of an automobile system: 1. Engine, chassis, and body. 2. Auxiliary electrical appliances and electronic equipment. Below is an introduction to the auxiliary electrical appliances and electronic equipment: 1. Auxiliary electrical appliances: automobile generator, battery, engine ignition and starting equipment, lighting and signaling equipment, instruments, air conditioning, wipers, audio and video equipment. 2. Electronic equipment: electronically controlled fuel injection system and ignition system, electronically controlled automatic transmission, anti-lock braking system (ABS), electronic traction control system, brake force distribution system, electronic stability program (ESP), torque vectoring system. Below is extended information about automobile braking system malfunctions: 1. When pressing the brake pedal, the pedal does not rise and there is no resistance. 2. When the brake pedal is pressed all the way down, the braking effect is poor; continuous braking does not improve the effect, and the pedal gradually rises. 3. Continuous braking causes the pedal to return and rise, with some improvement in braking effect. 4. Continuous braking causes the pedal position to rise, accompanied by a sinking sensation.

How to Deal with a Locked Steering Wheel in a Geely Car?

Solution for a locked steering wheel in a Geely car: First, insert the key and press the brake pedal, then turn the steering wheel left and right. Although the steering wheel is in a locked state at this time, it can still be slightly rotated when turning. While turning the steering wheel, turn the key simultaneously to complete the steering wheel unlocking process. Reason for the steering wheel lock: The steering wheel locks mainly because the steering wheel was turned when the key was removed after the last engine shutdown. At this point, the car's security anti-theft system perceives a risk of theft, so the system locks the steering wheel to prevent the vehicle from being stolen. Geely has many models, among which the Geely Borui, as a mid-sized family sedan, has body dimensions of 4956mm in length, 1861mm in width, and 1513mm in height, with a wheelbase of 2850mm.

Where is the beam of the car located?

Under the car body, there are two channel steels running from the front to the rear of the vehicle, which mark the position of the car beam. Below is a detailed introduction to the car beam: 1. The beam, also known as the frame, is the base of the car. It generally consists of two longitudinal beams and several cross beams, supported on the wheels via suspension devices, front axle, and rear axle. 2. The car beam is part of the car's chassis structure. However, most modern cars no longer use a beam-type chassis design, except for trucks and buses. The car beam is the main load-bearing component of a truck, carrying almost the entire weight of the cargo. The quality of the beam affects the vehicle's lifespan and driving safety. The manufacturing of car beams typically uses stamping forming processes, with bending as the primary deformation method. Therefore, the beam plate requires high formability, meaning the car beam steel plate must have excellent comprehensive performance, sufficient strength and toughness, good fatigue resistance, and cold formability. 3. The car beam provides strong body rigidity and enhances safety, which is particularly important for heavy-duty vehicles and off-road vehicles.
