A method of estimating an ideal air-fuel ratio in an internal combustion engine, comprises receiving an output of an upstream air-fuel ratio sensor and an output of a downstream air-fuel ratio sensor, the upstream air-fuel ratio sensor being attached to an exhaust gas passage such that it ...
Question: Consider an ideal turbojet engine with afterburner operating at the below conditions and, using excel sheet or MATLAB, generate the below performance curves of specific thrust, specific fuel consumption, fuel to air ratio, and efficiencies as f...
The ideal Utto cycle is changed to an ideal Diesel cycle with the same maximum pressure and same heat release.(The compression ratio will need to be changed to accomplish this.) Entropy b)The first half of the fuel-air mixture burns normal...
The remaining parts of the problem involve finding the gas temperature after combustion, the approximate rate of consumption of diesel fuel, the air-fuel ratio, and the volumetric efficiency of the engine. To solve these parts, one must have the value for the 'heat or energy content' of the...
aWith EGR, the engine can use a higher boost pressure and compression ratio to achieve a better performance and higher thermal efficiency for a stoichiometric air-fuel mixture 与EGR,引擎可能使用更高的升压力和压缩比达到一张更好的表现和更高的热效率为一个化学计量学的空气燃料混合物 [translate] a...

Frontline’s IsoCool™ product reduces the amount of power and energy required to compress the air by removing heat from each axial stage of compression via our patent-pending Q-Blade™ Technology. Depending on the pressure ratio, turbine power and application, this can save 5-10% in fuel...
Divers going to great depths in the sea are able to circumvent this problem somewhat by breathing a compressed helium-oxygen mixture in which the oxygen partial pressure is adjusted so that it is always equal to its value in atmospheric air at STP. Helium, being much less soluble in body ti...
