Actual Fuel Consumption of the Land Cruiser 4600?

Why does the car feel sluggish when stepping on the accelerator with AC on during a cold start in summer?

In summer, the car feels sluggish when stepping on the accelerator with AC on during a cold start, which may be due to poor valve sealing or excessive carbon buildup in the intake tract. Reasons for sluggish acceleration with AC on during a cold start: It could be caused by poor valve sealing and insufficient cylinder pressure; it might also result from excessive carbon buildup in the intake tract; another possibility is carbon buildup on the spark plugs or incorrect spark plug gaps; it could also be due to clogged fuel injectors, leading to insufficient fuel delivery. A detailed inspection is required to determine the exact cause. It is recommended to visit a 4S shop or auto repair shop for a comprehensive check. Causes of this common phenomenon: It is usually the result of multiple factors working together. First, unavoidable environmental factors come into play. In winter, temperatures are generally low, and the engine remains cold for a long time after starting. The engine oil inside the car becomes overly viscous, forcing the engine to operate under extreme conditions. This affects the engine's responsiveness. Compared to normal temperatures, acceleration in winter is relatively slower, sometimes taking a long time to respond. Additionally, in winter, the car's heating system starts working immediately upon startup. The water temperature in the radiator is insufficient to provide cabin warmth, so the heating system relies on the AC. Heating itself is highly energy-consuming, so the AC heating system also consumes a portion of the engine's output power. As a result, acceleration feels noticeably slower than usual.

What does it mean when the car body touches the parking space boundary line during parallel parking?

It means crossing the line, which is considered a failure. Crossing the line not only refers to the wheels touching the line but also includes the car body covering the line. Notes for parallel parking: 1. Reference points: Pay attention to the reference points during parallel parking. Be sure to remember the reference points designated by the instructor. When the vehicle reaches a certain point, quickly turn the steering wheel to complete normal entry into the parking space. 2. Steering wheel: Also note that when the vehicle is completely reversed into the parking space, the steering wheel should not be moved; otherwise, the vehicle will not be able to exit the parking space. 3. Parallel parking test standards: After the vehicle is parked in the space, if the car body crosses the line, 100 points will be deducted; if the wheels touch the lane boundary line while driving, 10 points will be deducted; if the vehicle is not parked within the space, 100 points will be deducted; if the left turn signal is not turned on when starting, 10 points will be deducted; if there is a stop during the process, 100 points will be deducted.

Does the Brake Disc Get Hot During Normal Driving?

During normal driving, the brake disc will become hot. There is slight friction between the brake pads and the brake disc during normal driving, which causes heating—this is a normal phenomenon. When the vehicle brakes, friction is generated between the brake caliper and the brake pads, leading to the brake disc heating up. This is also normal and has no adverse effects on the car as long as the heating remains within normal limits. Simply put, the brake disc is a circular disc that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force, which helps in slowing down or stopping the vehicle.

Is Four-Wheel Soundproofing Effective?

Four-wheel double-layer soundproofing shows noticeable effects. 1. Wheel arch soundproofing: It serves to prevent gravel and mud splashed up by the wheels during driving from reaching the underside of the cabin. 2. Function: Automotive soundproofing products originated in the late 1980s, developed by a group of American car audio enthusiasts to better enjoy the pleasures brought by car audio. It not only reduces interior noise during driving but also enhances the sound pressure and tone quality of car audio. 3. Principle: By applying damping materials and soundproofing materials to the vehicle, it reduces vibrations and noise transmitted through the car's metal structure, thereby improving driving comfort.

Under What Circumstances Is Fatigue Driving Prone to Occur?

Factors contributing to fatigue driving include: 1. Driver fatigue: Primarily involves fatigue of the nerves and sensory organs, as well as physical fatigue caused by prolonged maintenance of a fixed posture leading to poor blood circulation. Drivers sitting in a fixed position for extended periods with limited movement, while maintaining high concentration and being preoccupied with processing external stimuli, experience heightened mental tension. This results in symptoms of driving fatigue such as blurred vision, backache, slow reaction times, and impaired driving agility. 2. The sequence in which fatigue typically develops is: eyes, neck, shoulders, and waist, with the main focus being on eye and physical fatigue.
