What is the fuel consumption of the 2021 Haval 2nd Generation?

The official combined fuel consumption of the 2021 Haval 2nd Generation is 4.7-6.7L/100km. Currently, there are 6 models of the 2021 Haval 2nd Generation available for sale. The combined fuel consumption of the Haval King Rabbit is 4.7L/100km. The Gold Rabbit, Platinum Rabbit, and Silver Rabbit have a combined fuel consumption of 6.2L/100km. The Bronze Rabbit and Copper Rabbit have a combined fuel consumption of 6.7L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test cycle. The actual fuel consumption is higher than this value, ranging from 8.0-8.1L/100km. Methods to reduce fuel consumption: Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a high level of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional cleaning of the engine carbon deposits by technicians. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases during driving, and the oxygen sensor should be replaced immediately. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they become dirty and send incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased carbon deposits in the engine. Check the electronic control unit: Although the engine's electronic control unit is highly reliable, in older vehicles, various faults may inevitably occur.

What does variable speed limit on highways mean?

Variable speed limit on highways is used for roads and expressways to timely remind drivers of their driving speed. The speed limit value can be displayed through the monitoring center based on actual road conditions, thereby effectively guiding traffic flow, promoting driving safety, and improving the transportation capacity of the road network. Maximum speed of vehicles on highways: The maximum speed of small passenger cars on highways shall not exceed 120 kilometers per hour, other motor vehicles shall not exceed 100 kilometers per hour, and motorcycles shall not exceed 80 kilometers per hour. For two lanes in the same direction: The minimum speed of the left lane is 100 kilometers per hour. For three or more lanes in the same direction: The minimum speed of the leftmost lane is 110 kilometers per hour, and the minimum speed of the middle lane is 90 kilometers per hour.

What Does a Back-House Vehicle Mean?

Back-house vehicle refers to a car that cannot be transferred. Below is a detailed explanation: 1. A back-house vehicle is also an ordinary car, all procedures may have been completed, and annual inspections and insurance are normal, but the transfer of ownership is not allowed. 2. A back-house vehicle refers to a situation where an out-of-town individual spends money to find a local resident with household registration in the city to borrow their ID card for car purchase procedures. 3. Due to legal regulations, out-of-town individuals purchasing used cars in a certain city cannot directly transfer the vehicle under their own name. 4. Before September 2005, China's automobile management regulations stipulated that used cars under local management could not be sold or auctioned in other regions, requiring cross-region transfer registration. The vehicle's exit procedures were handled by the public security traffic management department at the place of origin, and the entry procedures were handled by the public security traffic management department at the destination. Hence, the phenomenon emerged where 'back-car groups' would pay a local resident to borrow their ID card for purchasing a vehicle.

Do Cars Consume More Fuel in Winter Than in Summer?

Cars consume more fuel in winter than in summer, and the specific reasons are as follows: 1. An engine's optimal working condition requires a certain temperature, generally around 90 degrees Celsius. Only when the engine is in good working condition will fuel consumption be normal. However, outdoor temperatures in winter are relatively low, and after starting, the engine needs a longer running time to reach its optimal working state, leading to increased fuel consumption compared to other seasons. 2. The operation of a car depends on the combustion of gasoline, which inevitably contains some impurities. Over time, these impurities can accumulate on the engine's surface, forming carbon deposits and sludge. This not only damages the engine but can also cause difficulties in starting, high idle speed, excessive exhaust emissions, and more importantly, increases the car's fuel consumption.
