CFM56 Tech Insertion
CFM has introduced advanced technology for two of its mature fleets: the CFM56-5B and -7B engines. Now built according to Tech Insertion production standards, CFM56-powered aircraft can release fewer emissions while flying at significantly lower operating cost.
Environmental Benefit
CFM56 Tech Insertion aircraft engines produce on average 28 percent fewer NOx emissions than the engine-lines it replaces, the base CFM56-5B and -7B.
Operating Benefit
If an airline were to replace a fleet of 20 aircraft with Tech Insertion engines it would save nearly $384,000 in fuel costs each year, compared to today's CFM56-5B and -7B engines.
CFM is lowering emissions
When CFM set out to reinvest in the CFM56-5B and -7B, two of the most successful aircraft engine fleets in the world, it did so with the environment and its customers in mind. CFM56 Tech Insertion aircraft engines produce on average 28 percent fewer NOx emissions than the engine-lines it replaces, the base CFM56-5B and -7B. NOx emissions from the CFM56 Tech Insertion engine models are also an average 26 percent lower than 2008 International Civil Aviation Organization regulations allow.
Every engine component improved with Tech Insertion is the result of years of innovation by some of the best engineers in the world. Advanced computer modeling techniques led to the design of new aerodynamic blades in the compressor, which is the heart of the engine, as well as improved cooling methods for the combustor. These steps forward in engine technology have resulted in better fuel efficiency that is maintained over time, and more durable engines.
Perhaps most impressive of all, Tech Insertion engines are pioneering CFM's most advanced combustor yet. NOx emissions from the combustor are below the maximum allowed by 2008 international standards with room to spare.
More information about CFM56 Tech Insertion
CFM56 Tech Insertion aircraft engines produce on average 28 percent fewer NOx emissions than the engine-lines it replaces, the base CFM56-5B and -7B. For each combined airplane takeoff and landing, this NOx reduction is equivalent to eliminating the NOx emitted by more than 350 passenger vehicles idling for an hour, which can potentially improve local air quality in the vicinity of the airport.
Over a 20-year life span, Tech Insertion engines sold in the next 10 years will also emit an estimated 9.2 million fewer metric tons of carbon dioxide than would have been produced by the engines they replace.
Compared to the current CFM56-5B and -7B powered fleets, an equivalent size fleet with CFM56 Tech Insertion engines would reduce annual carbon dioxide emissions more than 340,000 metric tons, the equivalent of:
- removing 66,000 cars from U.S. roads for a year or
- the amount of carbon dioxide absorbed annually by 93,000 acres of southeastern U.S. forest.
Compared to today's CFM56-5B and -7B fleet of aircraft, CFM56 Tech Insertion engines would save nearly 36 million gallons of jet fuel each year — enough to fill 8,900 jet fuel tanker trucks, or fly more than 3.4 million people from New York City to Chicago on Boeing 737 or Airbus A320 jets.
If an airline were to replace 20 of its aircraft with the latest Tech Insertion engines over the base CFM56-5B or -7B, it would save nearly U.S. U.S. $384,000 in fuel costs annually.
On average, the CFM56 Tech Insertion engine is expected to reduce Direct Maintenance Cost (DMC) by 6 percent when compared to the engine-line it replaces, due to its enhanced durability components and improved time-on-wing.
In total, more than 8,500 CFM56-5B and -7B engines have been delivered to more than 300 operators around the globe. The CFM56-5B is the engine of choice for the Airbus A318/A319/A320/A321 family. The CFM56-7B is the sole powerplant for the Boeing 737-600/-700/-800/-900/-900ER and 737 BBJ aircraft.
