What do MAX and ECO mean in the Binghu Car Refrigerator?

ECO stands for the initials of three English words: Ecology, Conservation, and Optimization. It is an energy-saving mode for vehicles. Activating this mode can achieve the effect of saving energy. The principle of ECO: ECO mainly involves making comprehensive judgments and analyses during vehicle movement regarding factors that affect fuel consumption, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal amount of fuel to provide to the engine for operation, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine speed with reasonable gear positions to reduce unnecessary fuel consumption. In a few cases, there is no need to activate ECO: When the car is driving at high speed (up to 100km/h), even if ECO is turned on, the vehicle's computer will prioritize speed, and the ECO mode will automatically deactivate. When a large torque output is needed, such as when climbing a mountain, the engine computer will prioritize ensuring and providing sufficient power to drive the vehicle, and the ECO mode will automatically deactivate.

What does DVP mean in the automotive industry?

In the automotive industry, DVP refers to Design-Verification-Plan, which is the test plan document. It includes bench tests and vehicle tests. The purpose is to ensure that the designed parts meet functional requirements and satisfy design specifications during future use. Type Approval Test: The type approval test for mass-produced vehicles is conducted before the official production of the vehicle or its main components. It aims to evaluate the performance, efficiency, reliability, durability, and adaptability of the vehicle or components to ensure they meet usage requirements. Inspection Test: This test is conducted during the vehicle production process to sample-check products and assess production quality. A certain number of products from each batch, or several vehicles per year or half-year, are selected for inspection tests according to specified procedures to identify and promptly correct any issues in craftsmanship or materials. Development and Research Test: This test is used for the development, research, design, and testing of new vehicle types, including new structures, materials, and theories. Since the methods and facilities used in automotive design and scientific research are largely similar, automotive manufacturers often establish design and research centers. These centers not only engage in product design and improvement but also conduct fundamental research to provide technical reserves. These tasks often require extensive testing.

How to Dispose of Scrapped Vehicles?

For vehicles with expired annual inspections that meet the scrapping conditions, after clearing all traffic violations, the scrapping procedures can be directly processed. Below is a detailed introduction to the disposal of vehicles that have reached their scrapping deadline: 1. Scrapping conditions: Light and mini trucks (including off-road types) and mining operation vehicles with a cumulative mileage of 300,000 kilometers; heavy and medium trucks (including off-road types) with a cumulative mileage of 400,000 kilometers; extra-large, large, medium, light, and mini buses (including off-road types) and sedans with a cumulative mileage of 500,000 kilometers; other vehicles with a cumulative mileage of 450,000 kilometers. 2. Other conditions: Additionally, vehicles that are severely damaged or in poor technical condition due to various reasons and cannot be repaired; models that have been phased out with no available parts; vehicles that, after long-term use, exceed the national standard fuel consumption by 15%; and those that still fail to meet the national technical safety requirements for motor vehicle operation after repairs and adjustments.

What Causes Steering Wheel Vibration at Speeds Above 130 km/h?

Tire dynamic imbalance, significant differences in tire pressure among the four tires, and poor four-wheel alignment can cause steering wheel vibration at speeds above 130 km/h. Tire Dynamic Imbalance: If a tire experiences a strong localized impact during driving, it can cause the balance weights to fall off or become damaged, thereby affecting the tire's dynamic balance. Significant Differences in Tire Pressure Among the Four Tires: When there is a significant difference in tire pressure among the four tires, especially between the left and right wheels, the car will experience noticeable body jolts and steering wheel vibration during high-speed driving. Poor Four-Wheel Alignment: When the four-wheel alignment has a large deviation angle, the car may exhibit phenomena such as body drift and vibration during high-speed driving. It can also lead to uneven tire wear, accelerating tire wear and shortening the tire's service life. Solutions for Steering Wheel Vibration at Speeds Above 130 km/h: When the car experiences steering wheel vibration at high speeds, the first step is to check and adjust the tire pressure. Then, perform a dynamic balance check on all four tires, and finally, conduct a four-wheel alignment.

What is the normal turbo boost pressure?

For ordinary family cars, the normal turbo boost pressure ranges between 1.2bar and 1.5bar. The maintenance methods for turbocharged engines are as follows: 1. Use high-grade synthetic oil: Since the combustion temperature and working pressure inside a turbocharged engine are significantly higher than those of a naturally aspirated engine during operation, turbocharged engines have higher requirements for lubrication and cooling. To ensure normal engine operation under more demanding working conditions, conventional mineral oil can no longer meet the requirements, and synthetic oil with better lubrication and cleaning capabilities must be used. Synthetic oil far surpasses mineral oil in terms of lubrication, cleaning, and anti-friction capabilities, and it also forms a lubricating film quickly, with high strength and good stability. Therefore, turbocharged models must use synthetic oil, preferably full synthetic oil. 2. Direct injection engines require the use of fuel injector cleaner: Direct injection sprays fuel directly into the cylinder, where it mixes with air. The ECU can precisely control the amount and timing of fuel injection based on the amount of air intake, ensuring that the air-fuel mixture burns more completely, thereby reducing fuel consumption and improving engine performance. However, because the fuel injectors in direct injection engines are placed directly inside the cylinders, they are prone to gum and carbon deposits. It is generally recommended to regularly add fuel injector cleaner to gasoline to clean the injectors. If the gum and carbon deposits on the injectors are severe, they need to be removed for cleaning. 3. Regular inspection: Due to the numerous components in a turbocharged engine, it is important to frequently check for unusual noises or vibrations in the turbocharger, and to inspect the lubrication pipes and joints for leaks. Check whether there is residual oil at the turbocharger exhaust outlet or oil on the walls of the compressor intake pipe. Oil consumption in turbocharged engines is not a common issue, but as a precaution, it is recommended that owners regularly pull out the engine oil dipstick to check oil consumption and ensure the oil level is within the normal range. If visible oil consumption is detected, it is best to visit a repair station for inspection as soon as possible.

Where are the A-pillar, B-pillar, and C-pillar of a car located?

A sedan body has three pillars, from front to back, they are the front pillar (A-pillar), middle pillar (B-pillar), and rear pillar (C-pillar). For sedans, these pillars not only provide structural support but also serve as door frames. The details are as follows: 1. A-pillar: The pillar between the front windshield and the left front door, which can obstruct the view when turning left. 2. B-pillar: The pillar located between the front door and the rear door. 3. C-pillar: The pillars on either side of the rear windshield. Additional information: 1. Front blind spot: The area in front of the car that is not visible from the hood, commonly known as the front blind spot. Several factors contribute to the front blind spot, including the height of the car body and seats, the length of the front end, and the driver's physique. 2. Rear blind spot: The blind spot behind the vehicle, commonly known as the rear blind spot, refers to an area of approximately 30 degrees extending outward from the rear door that is outside the view of the side mirrors. When the front of a following car is near the rear door of the leading car, the following car cannot be seen in the leading car's mirrors, making it prone to sideswipes and rear-end collisions.
