When Should You Turn On the Car ECON Mode?

1 Answers

07/25/25 1:27pm
If you are driving in congested traffic, it is recommended to turn on the ECON mode, but avoid using it on smooth roads. ECON is the car's energy-saving mode switch, and on some vehicles, the energy-saving mode is abbreviated as ECO. The name ECO is derived from the combination of Ecology, Conservation, and Optimization. From its inception, ECO has been designed with the fundamental principles of technology, environmental protection, and economy in mind. These three attributes have also become the enduring qualities pursued by the ECO intelligent engine family series. How ECO Works: ECO primarily operates by comprehensively analyzing and judging factors that affect fuel consumption during vehicle movement, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving modes.

What is the 729 car?

License plates starting with 729 in North Korea are designated for the exclusive use of the highest-ranking government officials. Vehicles bearing such plates are granted the highest level of road privileges in the country. Additionally, July 27, 1953, marks the anniversary of North Korea's liberation; hence, license plates like 727, 728, and 729 are indicative of individuals holding national-level status. Further details are as follows: 1. License plate colors: Similar to China, North Korea assigns different colors to license plates based on the nature of the vehicle. The primary colors used for North Korean license plates are white, black, yellow, red, and green. The most common license plates seen on North Korean streets are white with black characters, which denote government-owned vehicles. 2. North Korean vehicles: The majority of vehicles in North Korea are owned by institutions, making white plates with black characters a common sight. Many taxis in Pyongyang also feature these plates. Another frequently seen license plate type is black with white characters, which are used for military vehicles. Red plates with white characters are occasionally spotted on the streets, typically belonging to foreign organizations. Private vehicles in North Korea have yellow plates with black characters. However, private cars are extremely rare, and they are virtually absent from the streets of Pyongyang.

Causes and Solutions for Engine Water Pump Leakage

There are many reasons for engine water pump leakage, including severe wear of the bearing clearance inside the water pump, corrosion of the water pump by coolant, and damage to the mechanical shaft seal inside the water pump. In such cases, immediately stop the engine and call a 4S shop or repair shop to have professionals inspect and repair it. Below is a detailed explanation: 1. The function of the car water pump: The car water pump is mainly used for engine cooling to prevent the engine from overheating and causing the engine to "boil." The car water pump is generally located near the engine crankshaft and contains water. When the water level falls below the standard, it should be replenished promptly. 2. Solutions for water pump failure: When the car water pump fails, the car will exhibit symptoms such as weak acceleration and excessively high engine temperature. In such cases, immediately stop the engine and call a 4S shop or repair shop to have professionals inspect and repair it. Continuing to drive with a faulty water pump can cause damage to the engine, and in severe cases, may lead to engine failure. 3. Daily maintenance: The engine water pump is one of the essential components of a car. During daily use, it is important to perform regular maintenance to ensure the coolant level in the water pump is adequate. The water pump should be inspected every 20,000 kilometers driven.

What is the difference between No. 0 diesel and No. -35 diesel?

The differences between No. 0 diesel and No. -35 diesel are as follows: 1. Different freezing points: The freezing point of No. 0 diesel is higher than that of No. -35 diesel. Diesel is graded by freezing point, with light diesel having six grades: 5, 0, -10, -20, -35, -50, and heavy diesel having three grades: 10, 20, 30. That is, the freezing point of No. 0 diesel is 0 degrees Celsius, and the freezing point of No. -35 diesel is -35 degrees Celsius; 2. Different applicable temperatures: No. 0 diesel is suitable for environments with temperatures above 4℃, while No. -35 diesel is suitable for environments with temperatures between -14℃ and -29℃; 3. Different anti-freeze agent contents: No. 0 diesel has a lower anti-freeze agent content than No. -35 diesel. The main components of No. 0 diesel and No. -35 diesel are the same, and their combustion heat values are also the same. The difference lies in the content of anti-freeze agents. Generally, the higher the grade, the higher the minimum combustible temperature.

What Causes Abnormal Noises in the Vehicle Chassis?

Here are the reasons for abnormal noises in the vehicle chassis: 1. Noises during vehicle startup are generally caused by faults in the suspension system, possibly due to loose or damaged engine mounts. 2. Noises during vehicle steering may be caused by faults in the steering system or suspension system. As the vehicle tilts during steering, the suspension system deforms and participates in the movement. 3. Noises during driving on good road conditions may be caused by faults in the braking system components, such as loose or worn parts, out-of-round brake drums, or uneven brake discs. 4. It could also be due to issues with the bearings that connect moving and stationary parts. If it's a bearing issue, the driver can identify it by applying slight braking. If the noise remains unchanged when braking at a constant speed, it indicates a bearing problem. 5. Noises during driving on poor road conditions are mostly caused by issues in the suspension system or possibly loose braking system components. 6. Noises during acceleration, deceleration, or stopping are mostly caused by the suspension system or braking system. Friction sounds from the suspension system are common. To reduce these noises, drivers should avoid rough driving, minimize bumps, slow down on poor road conditions, and avoid driving through water, which can effectively reduce abnormal noises in the vehicle chassis.

Why Does the Shock Absorber Make Metal Noise When Cold but Not When Hot?

This situation usually occurs due to oil leakage from the shock absorber or damage to the shock absorber itself. The owner can inspect it themselves or visit a professional 4S shop or repair shop for inspection and maintenance, which may involve replacing the shock absorber. Below is some relevant information: 1. Definition of Shock Absorber: The car shock absorber (including the shock spring) is the most important component in the vehicle's vibration filtering system. 2. Function of Shock Absorber: It absorbs vibrations and impacts caused by uneven road surfaces during driving, thereby providing a comfortable ride for passengers. 3. Hazards of Damaged Shock Absorber: Once the shock absorber is damaged, the vehicle may experience excessive bumpiness and instability while driving, which can severely impact driving safety in serious cases. 4. Common Damages to Shock Absorbers: (1) Abnormal Noise: If the shock absorber makes unusual noises when driving on bumpy roads, it is highly likely that the shock absorber is damaged. (2) Oil Leakage: By using a flashlight to inspect the shock absorber through the wheel arch, if oil leakage is observed on the exterior of the shock absorber, it indicates that the shock absorber is already damaged. (3) Loose Chassis: When driving on bumpy roads, if the vehicle's body exhibits excessive bumpiness and instability, it is often a sign that the shock absorber is malfunctioning.
