Why is the new Emgrand often said to have high fuel consumption?

The fuel consumption performance of the new Emgrand with a 1.5L displacement can reach the standard of a 2.0L engine, with a combined fuel consumption of around 8.5L/100km. This figure generally applies to automatic transmission models, while manual transmission models are slightly lower, typically around 7.8L/100km. Although not as fuel-efficient as Japanese cars in the same class, it is not considered a fuel-guzzling model. The fuel consumption details of the Geely Emgrand are as follows: 1. MIIT fuel consumption: The Emgrand 1.5L 5-speed manual transmission model (China V) has a MIIT combined fuel consumption of 5.8L/100km, the Emgrand 1.5L 5-speed manual transmission model (China VI) has a MIIT combined fuel consumption of 5.8L/100km, the Emgrand 1.5L CVT model (China V) has a MIIT combined fuel consumption of 6.1L/100km, and the Emgrand 1.5L CVT model (China VI) has a MIIT combined fuel consumption of 6.1L/100km. 2. Actual fuel consumption: The Emgrand 1.5L 5-speed manual transmission model (China V) has a fuel consumption range of 6.82-8.75L/100km with an average of 7.78L/100km, the Emgrand 1.5L 5-speed manual transmission model (China VI) has a fuel consumption range of 6.68-8.62L/100km with an average of 7.65L/100km, the Emgrand 1.5L CVT model (China V) has a fuel consumption range of 7.58-9.92L/100km with an average of 8.76L/100km, and the Emgrand 1.5L CVT model (China VI) has a fuel consumption range of 7.42-9.71L/100km with an average of 8.58L/100km.

Should You Use Internal or External Air Circulation for Defogging on Rainy Days?

If you want to quickly defog, it is recommended to turn on the external air circulation. If it's not raining heavily, you can also open the windows slightly for faster defogging. Below is an introduction to homemade and professional defogging sprays: Defogging with Homemade Spray: Mix dish soap and water in a ratio of 1:10 (or dishwashing liquid and water in a ratio of 1:6), then apply it to the inside of the front and rear windshields with a soft, clean cloth. After it dries, wipe off any remaining watermarks on the inside of the glass. This method can generally keep the glass fog-free for up to 20 hours, is simple, practical, and cost-effective. The effect is comparable to commercial defogging products—just spray and wipe to solve the problem. Defogging with Professional Defogging Spray: Before using a defogging spray, first clean the inside of the front windshield thoroughly. Then, spray an appropriate amount of the defogging agent and wait for it to solidify before wiping it off with a clean towel. The defogging agent forms a hydrophobic layer between water molecules and the inner surface of the glass, keeping the glass surface clean and preventing fogging.

Can a full-size spare tire that's 5 years old be used as a new tire?

It's okay to use a spare tire for a few days, but it should not be used for an extended period. It's best to replace the spare tire with the original tire once the vehicle is driven to a repair shop for fixing. Precautions for using a spare tire: Although there are no strict regulations on the mileage or duration for using a spare tire, speed should be limited, especially for non-full-size spare tires, with a maximum speed not exceeding 80 km/h. Storage duration of a spare tire: A spare tire that has been stored for 5 years cannot be used as a new tire. Even though the tread may still appear new due to infrequent use, spare tires are made of rubber. Over time, typically within 3-5 years, they undergo natural aging, which is mainly characterized by numerous small cracks on the tire sidewalls or hardening of the tire. At this point, the tire's performance has significantly deteriorated, and continued use poses a risk of a blowout. Therefore, a spare tire stored for 5 years should not be used as a new tire.

Will Traffic Violations Always Be Captured by Cameras?

Traffic violations may not always be captured by cameras. Firstly, it depends on whether the violation is obvious, and secondly, it depends on the system's judgment and whether the violation is identified manually. Drivers should always strive to follow traffic regulations. Working Principle: Traffic violation cameras work in conjunction with induction loops. Repeatedly crossing the line will not be treated as running a red light but will be penalized as stopping beyond the line. According to Article 4, Item 5 of the "Scoring Standards for Road Traffic Safety Violations," driving or stopping at an intersection in violation of regulations will result in a 2-point deduction. If a vehicle stops beyond the line and then reverses, it may be subject to a warning or a fine. Operation Process: The high-definition red-light running electronic police system utilizes advanced technologies such as optoelectronics, computer systems, image processing, pattern recognition, and remote data access. By leveraging the condition that each vehicle corresponds to a unique license plate number, the system continuously and real-time records the images of every passing vehicle and its license plate on monitored roads, operating around the clock.

Does engine oil affect fuel consumption increase?

Engine oil affects fuel consumption. It provides good lubrication for the engine, reducing friction, cleaning, cushioning, and sealing. Poor lubrication: If the engine oil provides poor lubrication, it will increase the engine's movement resistance, leading to higher fuel consumption. Therefore, engine oil not only affects fuel consumption but also the engine's lifespan. It is recommended to change the engine oil every 5,000 kilometers. Long-term use of engine oil: After prolonged use, engine oil gradually deteriorates, reducing viscosity and lubrication efficiency, which increases friction. Over time, this causes severe engine wear, enlarging the gaps between moving parts. As a result, the engine may produce abnormal noises, which grow louder with increasing wear.

Should I Inflate My Tires to 2.2 Bar in Autumn?

You should inflate your tires to 2.2 bar in autumn. Winter temperatures are relatively low, and due to thermal expansion and contraction, tire pressure will also change. Generally, the normal range for tire pressure is around 2.5 bar, which is suitable for regular use. However, as winter approaches, the tire pressure should be increased slightly. Typically, adjusting it to 2.6 bar is the most appropriate and safest range. Tire pressure standards for different types of tires: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.
