Efficiency of a gas engine
WebIn the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption ...

Transients prompted by significant changes in thrust or power demand are common and unavoidable. Extreme transient scenarios such as those associated with a go-around during a landing attempt are possible and must be accounted for in the design of the …
WebThe table below shows an example of the cumulative system efficiency of a gas engine. If a less electrically efficient model is used, over-all efficiency can be in excess of 90%. However the relative commercial value of the electricity is typically much higher than that of the heat, and hence the drive is for more electrically efficient engines. WebThe combustion temperature of gasoline is about 550K. So the Carnot limit for a gasoline-burning engine outdoors is roughly $$ \epsilon_C = 1-\frac{T_f}{T_i} = 1 - \frac{275 \mathrm{K}}{550 \mathrm{K}} =50\% $$ Here I've taken the output temperature to be near freezing, which is a rudimentary estimate at best (as dmckee points out). This ...
