What does gasoline ULR91 mean?

U.S. cars are marked with 87 (Research Octane number 91) or higher, which translates to U.S. No. 87 or above unleaded gasoline (No. 91 octane number or above unleaded gasoline). Ordinary No. 87 gasoline, which is the most used in the United States (more than 90 per cent), has a nominal octane number of 91 92 measured by the research method and 82 83 by the motor method, both of which are averaged in nominal terms.

This is the gasoline marking! Gasoline marking: It is the ratio of the anti-knock resistance of actual gasoline to the anti-knock resistance of standard gasoline.

Standard gasoline is composed of isooctane and n-heptane. Isooctane has good knock resistance, and its octane number is set at 100; N-heptane has poor knock resistance, and is prone to detonation on gasoline engines, and its octane number is set at 0. If the gasoline is marked 90, it means that the gasoline of this grade has the same anti-knock properties as standard gasoline containing 90% isooctane and 10% n-heptane.

For example, No. 90 gasoline can ensure that there will be no deflagration when used on an engine with a compression ratio of no more than 9, and No. 97 gasoline can be guaranteed to be used on an engine with a compression ratio not greater than that without deflagration. The higher the grade, the stronger the anti-explosion performance. Standard gasoline is composed of isooctane and n-heptane.

However, it is not that the higher the grade, the better, and the gasoline grade should be reasonably selected according to the engine compression ratio. In December 2011, Beijing proposed to revise the gasoline grade from "No. 90, No. 93, No. 97" to "No. 89, No. 92, No. 95", and stipulated that the sulfur content should not exceed %.

Hope it helps you to hope thank you!

In the automotive industry, the resource car refers to:The car of the resource company。The upstream vehicles of resource vehicles are manufacturers or car 4S stores, and it seems that there will be no problems with these cars from the source of the car, but the reality is that many consumers who want to buy low-cost cars through resource companies have paid a greater price.

There are many resource companies that will also install some low-profile vehicles and change them to high-profile versions, which not only sell the best that should not be sold, but also move the circuit and other systems, which is more risky. Du Long, head of Geely Central China, told reporters that the condition of these vehicles is often difficult for manufacturers to grasp, and consumers not only spend more money, but also have risks in actual use.

In addition, many resource cars have the problem of selling old models, the staff of Henan Automobile Industry Association told reporters that the vehicles in the car market will have a large number of new cars launched almost every year, and some old vehicles will also carry out certain facelifts and upgrades every year, and launch the era of vehicles.

These mid-term facelift era vehicles, often this year and last year's difference is not big, not the industry, sometimes it is difficult to distinguish whether it is the most ** model. The person in charge of a Japanese 4S store told reporters that even he himself is sometimes difficult to distinguish, let alone ordinary consumers, and some resource companies take advantage of this information asymmetry to sell old cars to consumers.

Resource vehicles and 4S shop vehicles.

Difference: 4S shop vehicles are palletized from the factory.

Shipped to the store for sale to customers. The resource car refers to the factory consignment version to the 4S store, and the 4S store resells the right to the automobile trading company, and then sells it to the end customer by the middleman. To put it simply, auto trade scalpers find more favorable models of the same model from 4S stores in other places and sell them to end customers to earn the difference.

Features of the resource vehicle:1From the 4S store in other places to drive back to the local area, rather than in the form of consignment, the new car is in the middle of the run-in period, and the high-speed vehicle is damaged by the run-in.

Generally, customers are more mindful of the new car driving around for a long time, and they can't accept it. 2.Generally, part of the car is prepaid first, and then the auto trade begins to find resource cars across the country.

That is to say, if you want to pay for the car with one hand and the car with the other, or pay the car before the car, this purchase method will not work, and there is a transaction risk in the middle. 3.The invoice for the purchase of the car is inconsistent with the unit that collects the money, to put it simply, B takes C's car and sells it to A, but A and C have never met, and finally B collects the money and C issues the invoice, and A and C do not have a buying and selling relationship.

If there is a problem, it is not possible to defend the rights. 4.Resource vehicles are generally vehicles that 4S stores are unwilling to sell themselves, so they are sold to middlemen.

4S shop sell-offs are all selective sell-offs, and there may be problems with the vehicle itself.

In short: the resource car will not affect the maintenance and repair of the license plate in the later stage, but if the price difference is not big with the 4S store in the local area, it is recommended not to buy. If the price difference is large, you need to invite professionals to help inspect the car.

The factory consigns to the 4S store, which resells it to the auto trading company, and then sells it to the end customer by the middleman. To put it simply, auto trade scalpers find more favorable models of the same model from 4S stores in other places and sell them to end customers to earn the difference.

A car is a vehicle that uses gasoline, diesel or natural gas as an energy source and is powered by an engine. Vehicles that generally have four or more wheels and are able to travel on land without relying on tracks or wires.

It means that you will transfer the car from another store, pay attention to the production date and whether there is a maintenance record, etc., if you win the lottery, you will lose three, but it is a very small probability of the grand prize in Toyota.

There are two kinds of vehicles produced by each automobile manufacturer: one is a retail vehicle (that is, a small batch order from a 4S store, and the highest in the factory) and the other is accommodating.

It is a bulk order of the automobile trade company (due to the large order volume, sometimes hundreds or even tens of thousands of units, so the factory ** is low; This kind of car is usually called a resource car in the industry), and there is no difference between the two vehicles and the national joint warranty. At present, many vehicles in 4S stores are taken from auto trading companies (most of the stores in 4S stores without capital are resource vehicles), but the current market environment is chaotic, and there are shoddy ones, such as slight scratches in transportation, and vehicles are also flooded in the ranks of resource vehicles after repair.

Changan Automobile is produced in Chongqing, and the manufacturer is Chongqing Changan Automobile Co., Ltd.

Changan Automobile is one of the four major automobile groups in China, with 16 production bases, 35 vehicle and engine plants and 10 key overseas markets.

At the same time, Changan Automobile actively seeks joint ventures and cooperation, and establishes joint ventures such as Changan Suzuki, Changan Ford, Jiangling Holdings, Changan Mazda, and Changan Peugeot Citroen.

Extended Materials. The history of Changan Automobile can be traced back to the period of the Westernization Movement, which originated in 1862 from the Shanghai Marine Artillery Bureau, and created a precedent for China's modern industry. With the tide of China's reform and opening up, Changan officially entered the automotive field in the early eighties of the last century. In 1996, it was registered and became a highly competitive listed company, and currently has 2 listed companies and 4 **.

Founded in 1862, Chang'an is the oldest industrial enterprise in China. Spanning three centuries and going through a hundred years of vicissitudes, Chang'an has always pursued the pace of human civilization. In 1957, China's first jeep was born in Chang'an, and in 1983, China's most valuable small car brand "Chang'an" was born.

Chang'an and automobiles are afflicted, which is Chang'an's choice for social progress and history's choice for Chang'an's development. Today, Changan has become the largest integrated manufacturing enterprise of automobiles and engines in China, with more than 20,000 employees, total assets of 11.3 billion yuan, an annual production capacity of 300,000 vehicles and 360,000 engines, and has put more than 100,000 Changan automobiles of various types on the market. In 2001, Chang'an's output value and income both exceeded 10 billion yuan, becoming the first "double 10 billion" enterprise in Chongqing and even the entire national defense system.

Changan currently has seven major automobile manufacturing enterprises: "Changan Automobile Co., Ltd.", "Changan Ford Automobile", "Changan Suzuki Automobile", "Nanjing Changan Automobile", "Hebei Changan Shengli", "Hebei Changan Automobile" and "Changan Leapfrog Vehicle". The brand value of "Changan" has reached 100 million yuan, becoming the most valuable automobile brand in the domestic small car industry and ranking among the top 20 automobile brands in the world.

Coming from the Westernization Movement in 1862, growing up in the tide of reform and opening up, and growing in the waves of the intersection of the century, Changan Automobile, a generation of famous cars, is creating a new era in the development of China's automobile civilization. The ancient and young Chang'an, like a shining rising star, is facing the fiery morning sun in the new century, moving towards new glory and hope!
