New fuel-efficient approach: Michelin fuel oil 100 km 4L

On November 14, 2011, the Ministry of Transport Car Trailer Quality Supervision, Inspection and Testing Center and Michelin jointly announced that the Michelin fuel-efficient tires passed the two-day test of the Ministry of Transport's testing ground. Michelin's oil has inner-tube fuel-efficient tires and tireless tires with no inner fuel-efficient tires. Ordinary tires save fuel by 3.8% and 4.5% respectively, and the comprehensive fuel-efficient efficiency is about 4L.

Authoritative inspections add evidence to fuel-efficient tires

The Ministry of Transport Car Trailer Quality Supervision, Inspection and Test Center is the first large-scale comprehensive experimental base built by the Ministry of Transport of the People's Republic of China to carry out experimental research on automotive engineering, traffic engineering, and highway engineering at the same time. According to Minister Yang of the test center, " This test refers to GB/T12534-1990 "General Rules for Automotive Road Test Methods" GB/T2977-2008 "Specifications, Dimensions, Pressure and Load of Heavy-duty Vehicle Tires" GB/T12545.2 "Test Methods for Fuel Consumption of Commercial Vehicles", The Michelin tire fuel consumption experiment stipulated by both parties adopts a speedometer, a standard tester such as a host, a flowmeter, a meteorological meter, and a fuel density meter, and uses two FAW liberation trucks with the same or similar parameters. car."

Measurements were divided into two groups. Michelin 11.00R20 XZA 2 Energy & XDA 2 Energy and 315/80R22.5 XZA 2 + Energy/XDA 2 +Energy were used respectively. Samples were first tested with inner tires and fuel-efficient tires. Test of tube tires and fuel-efficient tires, sample cars driving at a speed of 60km/h for 30km to complete preheating, and then measurement sample vehicle A and measurement sample vehicle B for a constant speed of 60km/h driving through 5km of fuel consumption (continuous measurement 3 times); Afterwards, the vehicle sample A and the measurement sample vehicle B are measured in the same way and the fuel consumption of a constant speed of 50 km travels at a speed of 60 km/h. The final comprehensive data shows that Michelin's fuel-containing inner-tube fuel-efficient tires and tire-free fuel-efficient tires save fuel by 3.8% and 4.5%, respectively, compared to ordinary tires.

Tyre saving is also a way to improve operational efficiency

Little is known: Tyre saving is also a way to increase operating efficiency. Michelin proves the fuel-saving performance of tires through authoritative testing, user experience, and original test, which provides new options for improving the operational efficiency of roads. Looking at the historical data of refined oil price adjustments in recent years, we can see that the prices of domestic refined oil products have been constantly changing, and their characteristics are characterized by rising or falling, and they continue to rise in fluctuations. As far as diesel is concerned, the retail price in recent years has also shown a continuous and substantial increase. Taking the Beijing area as an example, the retail price of diesel No. 0 per litre on May 10, 2005 increased from 3.49 yuan to 3.62 yuan; in 2006, it exceeded 5 yuan to 5.02 yuan; on February 20, 2011, it exceeded 7 yuan, and thereafter Continue to be above 7 yuan.

With the continuous rise of oil prices, the pressure on vehicle operators is increasing, and the emergence of fuel-efficient tires will effectively relieve this pressure. Taking a car with a fuel consumption of 35L per 100 km and 200,000 km per year, the use of fuel-efficient 4% of Michelin tires at a fuel price of 7.5 yuan per liter can save 21,000 yuan per year, for a fleet of 50 vehicles. You can save 1.05 million yuan / year. Users from Hangzhou Guang'an Cargo Transport Company stated that vehicles using Michelin fuel oil tires can save fuel costs by 10 yuan per 100 kilometers, and the company’s 60 vehicles can save 1.26 million yuan per year, which greatly eases the increase in fuel prices. Operating costs pressure.

Michelin Card Customer Experience Manager Zhang Hongbing admitted frankly that “the purchase price of Michelin oil tyres is different from other tyres in pricing, but because tyres only account for 6% of vehicle costs, fuel costs are 40%, saving 21,000 yuan of fuel per year. Cost calculations can buy another 6-7 Michelin tires. After hundreds of thousands of kilometers of driving, the Michelin tires' full life cycle also includes a ditching + 2 refurbishments, and its overall economic return will be even higher."

Fuel-saving tires full range of products can try

According to Michael, a truck and truck marketing director who has worked for Michelin for 34 years, tire rolling resistance consumes about 35% of the fuel needed for vehicle operation. In order to reduce rolling resistance, Michelin started adding silicon to rubber formulations in 1992 to save tires. . Since then, in August 2006, XZA 2+ Energy, an all-wheel tireless tire for highways, luxury passenger cars, passenger cars and trucks, was launched. In August 2010, all wheel positions for long-distance highways and national highways were introduced. All-weather tubeless tire X Coach XZ Energy, and in March 2011 launched the XDA2 Energy, XDA2+ Energy, an energy-efficient driveline for long-distance high-speed driving. So far, Michelin's fuel-efficient tires can be used in city buses, coaches and truck.

Taking the Michelin 12R22.5 X Coach Energy XZ tire as an example, it adopts a special compound formula containing silicon, which has the main features of long mileage, energy saving, high efficiency, safety and comfort. By using Michelin's durable technology, the tread pattern of this tire has an interlocking function that can effectively counter irregular wear and tread thorns, thereby giving the user a longer mileage experience. The tire is a low flat ratio tubeless tire with a ratio of sidewall height to tread width of 90%, which reduces the vehicle's weight compared to conventional inner tube tires (aspect ratio is 1:1, ie 100%). The center of gravity improves the handling and safety of the vehicle. In addition, the Michelin 12R22.5 X Coach XZ Energy also has outstanding advantages such as “slow nailing,” “low operating temperature,” and “convenient maintenance” as tubeless tires (so-called “vacuum tires”). At the same time, this tire also has fuel efficiency of up to 5%.
