May 11, 2015 Beijing international road transport, urban public transport and Parts Fair (hereinafter: Beijing Bus Exhibition) opened domestic natural gas Cummins Engine series of new products –B6.7G released.
B6.7G Cummins Following the launch of the first domestic natural gas engine L8.9G new products last year, overlay 190-255 hp, to meet the country five (Beijing five) emission standards. As Cummins local R & D, the second paragraph of locally manufactured engine, B6.7G 8-12 meter bus and passenger vehicles tailored to meet the needs of mainstream Chinese passenger car market. The introduction of this engine to further improve the domestic natural gas engines Cummins product line, providing a richer horsepower segment selector for the Chinese user
Cummins Natural Gas Engine B6.7G
“The success marks the launch of Cummins B6.7G further improved ‘service Chinese mainstream market’ product chain.” Cummins, vice president and general manager of Dongfeng Cummins Engine Co., said Wang Ning, “China’s economy has entered a ‘new normal,’ ‘ environmental clean blue sky ‘is a general trend, people want. Domestic natural gas project is based on Cummins engines mature production technology and platforms, chain together the world’s most advanced technology and rich experience in the application of Cummins to achieve local development in China, local production, local services , which started five countries meet emission standards, further evidence of our ‘technology pioneer, driving a green future’ commitment. ”
“B6.7G uphold the power of Cummins products, good reliability, excellent quality cleaning and environmental protection while digging fuel economy and oil consumption, significantly reducing user costs.” Cummins (China) Investment Co., Ltd. Engine Steve Saxby Technical Director Business Unit.
It is understood, B6.7G rely on Cummins B series engine platform developed by a number of assessment tests, including the most demanding thermal shock experiments, super hot load test and oversized load test. In addition to the bench, the engine but also to withstand the test of combat, complete 1.2 million kilometers of road test mileage accumulation.
B6.7G natural gas engines Chinese bus market is the most commonly used models developed for the 8-12-meter bus, peak torque up to 860Nm, and has a wide range of smooth torque. For frequent buses started operating conditions, well-tuned low-speed torque, 650Nm to reach the clutch torque.
Meanwhile, B6.7G natural gas engines can meet the national five (Beijing V) emissions standards, together with the ECM-controlled precision knock control management system, so that the engine gas qualities for external changes, temperature and humidity have a strong adaptability. In complex industrial environments, without worrying about engine knock, cylinder head cracking, melting of the piston top and other issues.
In addition B6.7G engine, Cummins booth on display at the two from Dongfeng Cummins diesel engine products –ISDe6.7L and ISL9.5L.
ISDe6.7 liter, inline 6-cylinder, power covers 185-300 hp, to meet the country Ⅲ / Euro Ⅲ, country Ⅳ / Europe Ⅳ, country Ⅴ / Euro Ⅴ emission standards, the maximum torque up to 1100 Nm, power reserve and transient Excellent response. Engine connection size with the country Ⅲ, Europe Ⅴ consistent, vehicle upgrades easy match, especially for the 8-12 meter buses, intercity buses and hybrid buses within 12 meters.
ISL9.5 liter, inline 6-cylinder 292-425 hp, to meet the country Ⅲ / Euro Ⅲ, country Ⅳ / Euro Ⅳ emission standards for inter-city buses over 12m. ISL9.5 EHV Cummins fuel system, when the variable injection timing to achieve optimal burning whole speed range and the full load range, to minimize fuel consumption. EBP witty people saving system that helps the driver depending on the road conditions, load cases, the flexibility to choose power, standard and economy key third gear is selected to achieve interaction engines, vehicles and motorists. Po means fuel oil filter impurities can significantly improve the reliability and durability of the fuel system, the better the oil adaptability. Electronic fan can control the fan speed according to engine temperature, the engine to maintain a reasonable temperature, to achieve fuel efficiency.
