The first results were very encouraging, with more power and lower specific fuel consumption than the gasoline version.

Both these engines had high specific fuel consumptions and were noisy.

Together the improvements provided a 1.2% improvement to the Trent 700's specific fuel consumption.

Another number that measures the same thing, usually used for air breathing jet engines, is specific fuel consumption.

Due to the lower specific fuel consumption and higher thrust rating the design of the A340 was modified.

They achieve specific fuel consumptions of between 183 and 196g/kWh.

Running the engines at a relatively high thermal temperature was expected to improve the specific fuel consumption.

It shows the result of specific fuel consumption.

The engine features a high overall pressure ratio, yielding a low specific fuel consumption for its time.

See Brake specific fuel consumption for more information.

Fuel economy, or thrust specific fuel consumption in aircraft terms, is extremely poor.

This is reflected in improvements in the engine's specific fuel consumption.

The TR-1 was not a success, proving to have less thrust and a higher specific fuel consumption than designed.

In fact, the HF120 is expected to have the lowest specific fuel consumption in its class.

The following table takes selected values as an example for the minimum specific fuel consumption of several types of engine.

Specific fuel consumption is used extensively for describing the performance of air-breathing jet engines.

Another equivalent unit is specific fuel consumption.

While the thrust-to-weight ratio is excellent, thrust specific fuel consumption is very poor.

Engines designed or modified for systems specified in 6-1.A., regardless of thrust or specific fuel consumption.

The latter score in having up to 25% lower specific fuel consumption and much lower CO 2 output.

The Nomad compound engine achieved a specific fuel consumption of 0.345 lbs per horsepower-hour.

Alternative may be offering a more expensive lubricant and promise return in lower wear, specific fuel consumption or longer drain intervals.

Current direct-injection diesels are comparatively high on particulate output, though specific fuel consumption is good.

The Nomad II had the lowest specific fuel consumption figures seen up to that time.

Typical pulse jet engines have extremely poor fuel efficiency, specific fuel consumption, and thrust.
