combustion efficiency

[kəm′bəs·chən i′fish·ən·sē]
(chemistry)
The ratio of heat actually developed in a combustion process to the heat that would be released if the combustion were perfect.

Combustion efficiency

The efficiency at which a fuel is burned in a combustion appliance when operating at its rated output; the combustion efficiency is always higher than the annual fuel utilization efficiency (AFUE).

combustion efficiency

The ratio of energy released to the potential chemical energy of fuel. Both variables are expressed as a rate. It can also be described as the ratio of actual temperature rise to the theoretical temperature rise in jet engines.

x]) and combustion efficiency were performed by using the gas analyzer TESTO 350 XL.
When using a condensing water heater for space heating, maintaining a condensing water heater above 130[degrees]F (54[degrees]C) will result in decreased combustion efficiency, and should be avoided by designing the system for low-temperature operation.
But all eyes have been on the Optimal Drive system, which is made possible by new engine technologies and advanced transmissions with low-friction components, lightweight compact design and enhanced combustion efficiency.
The Optimal Drive technology focuses on reducing engine weight and any unnecessary mechanical losses whilst maximising combustion efficiency.
AFUE is "annual fuel utilization efficiency," a measure of average combustion efficiency in a furnace or heating unit.
In addition, the increased combustion efficiency, power and torque results in higher low-speed torque and faster response, while the new ECU has twice the memory and five times the computing power of the previous engine.
At low outputs, the heat loss to the combustion chamber walls is proportionately greater and combustion efficiency is poorer, resulting in higher fuel consumption for the power produced.
