At the first day of the 2014 Beijing International Road Transport Exhibition, Cummins' first natural gas engine developed and produced in China, the L8.9G, unveiled its mysterious veil and attracted numerous eyeballs for its public premiere.

The L8.9G natural gas engine is an eye-catching job in the field of green power. The power covers 250-320 hp and meets the national five emission standards. It is the first natural gas engine that Cummins has built specifically for the Chinese market. It has consolidated global R&D strength and cutting-edge technology and has undergone a number of rigorous tests to meet a variety of operating conditions and needs. L8.9G inherits Cummins' reliable and enduring classic quality, while its power and economy are particularly prominent.

"The successful listing of L8.9G marks Cummins taking another solid step towards the goal of serving China's mainstream market," said Dr. Peng Lixin, the company's chief technologist. "In order to better serve Chinese users, we not only need to introduce the most advanced technology and internationally into China, but also need to intensively cultivate China's mainstream market and tailor the most suitable products and technologies to meet our customers' needs. We will link global resources and promote local development. R&D, local production, and local services to respond quickly to customer needs."

L8.9G brings together Cummins' most cutting-edge R&D forces to build with Cummins' R&D team in China, and Cummins' global superiority resources. This new natural gas power platform is based on proven and proven products. It not only integrates Cummins advanced natural gas power technology, but also fully considers the specific needs of Chinese users, ensuring that this product provides superior power while achieving cost-effective performance. Sex, environmental protection and reliability have become the natural gas power that the market really needs.

Cummins is a pioneer in global gas power technology. As early as the 1960s, the research and development of natural gas power began. In the 1980s, Cummins's first natural gas engine for vehicles was successful when it was launched. At present, in the global context, Cummins has a total of six R & D centers working together to jointly participate in the development of natural gas engines.

“Global demand for natural gas power is growing because customers are increasingly recognizing the low cost and environmental benefits of natural gas,” said Roe East, general manager of Cummins' global heavy-duty gas business. “With a large number of Chinese passenger car and truck manufacturers starting to produce natural gas vehicles, the increasing popularity of natural gas filling stations and the attractive price advantage of natural gas, China is becoming the world’s most important natural gas engine market, and the local production of natural gas engines. It is also an important layout of Cummins' global natural gas strategy."

At the launch site, the first batch of user representatives of L8.9G stated: “The L8.9G engine is very dynamic and economical during testing, and its failure rate is extremely low. Its excellent reliability ensures the efficient operation of the fleet. "In terms of services, the representative also said:" Cummins selected a team of senior technicians on-site for our company. At the same time, it also has factory, branch and on-site three-level spare parts reserves, and provides backup machines to ensure rapid response. In addition, they also train our service technicians and help improve our self-service capabilities. This excellent service quality is the cornerstone of our long-term friendly cooperation with Cummins."

The Cummins L8.9G natural gas engine combines three major advantages:

Better and more durable

L8.9G adopts the world's leading natural gas technology research and development platform and the industry's most professional simulation and simulation tool (CAE). It integrates the world's top bench testing equipment and the overall development process lasted for more than 2 years. The unique domestic real-time gas analysis function enables the product to adapt to gas in different regions and has a wide range of applications. The accumulative bench test verification time exceeds 8000 hours, and in particular, the industry’s most severe thermal shock test with more than 10,000 duty cycles was conducted, and the actual operation of the entire vehicle in the Chinese market was conducted, and 600,000 km of actual road tests were conducted to ensure The engine operates reliably for a long time under various application conditions.

To Zhiqiang Power Co., Ltd.

L8.9G natural gas engine power up to 26.4kw / L, higher than similar products in the market. With a maximum torque of 1200 Nm., it also has a wide range of peak torque torque and excellent power performance. The clutch engagement torque can reach 730 Nm. Compared with similar products, it exceeds 15%, which greatly enhances vehicle starting performance.

Green efficiency saves

L8.9G natural gas engine realizes the cost savings of the whole life cycle while meeting the national five emission standards: localized manufacturing and procurement strategies, effectively reducing the cost of customer acquisition; innovative design and unique performance tuning, improving fuel economy, and reducing fleets Operating costs; modular design, low failure rate, optimized service channels and fittings systems, and reduced fleet maintenance costs. In addition, combining the road conditions of the Chinese market and driver's driving habits, relying on Cummins's years of applied experience, the vehicle can be perfectly matched to provide maximum value for users.

In addition to the L8.9G engine, two diesel engine products from the Dongfeng Cummins, ISDe6.7L and ISL9.5L, were on display at the Cummins booth.

ISDe 6.7-liter engine, in-line 6-cylinder, power coverage 185-300 hp, meets National III/Euro III, National IV/Euro IV, National V/Euro V emission standards, maximum torque up to 1100 Nm, power reserve and transient Excellent response performance. The engine interface size is the same as that of the country III and Europe V. It is more convenient to upgrade and match the vehicle. It is especially suitable for 8-12 meters of bus passenger cars, intercity buses and hybrid buses within 12 meters.

ISL 9.5-liter engine, in-line 6-cylinder, 292-425 horsepower, to meet the national III / Euro III, the national IV / Euro IV emission standards, apply to more than 12m intercity bus. ISL9.5 uses Cummins ultra-high pressure fuel system, variable fuel injection timing, to achieve the best combustion state within the full speed range and full load range, to minimize fuel consumption. EBP's Homo sapiens energy-saving system can help the driver to flexibly select the power, standard, and economic three-speed selection keys according to different road conditions and bearing conditions to achieve the interactive communication between the engine, vehicle and driver. Oil and water treasure device can filter fuel impurities, greatly improve the reliability and durability of the fuel system, oil better adaptability. The electronic fan can control the fan speed according to the engine water temperature, so that the engine maintains a reasonable temperature to achieve the fuel-saving effect.
