The Boeing Next-Generation 737 Family
Advanced Engine Technology
The Next-Generation 737 models are powered by new CFM56-7 engines produced by CFMI, a joint venture of General Electric Co. of the U.S. and Snecma of France.
- In April 2009, Boeing and its engine partner, CFM, announced a 2 percent reduction in fuel consumption by 2011 through a combination of airframe and engine improvements. Airplane structural improvements will reduce drag on the airplane, reducing fuel use by about 1 percent. CFM is contributing the other 1 percent fuel savings through hardware changes to its engine.
- In 2007, Boeing and CFM introduced the CFM56-7B tech insertion engine which provides lower emissions and longer time on wing.
- The engines meet community noise restrictions.
- The engines provide up to 27,300 pounds of thrust (Boeing equivalent thrust value).
- They offer longer time on wing resulting in lower engine maintenance costs.
- The CFM56-7B has a higher thrust capability than the CFM56-3C engines powering the 737-300/-400/-500 models.
