Even more advanced devices allow users to reset engine DTC codes, effectively turning off engine lights in the dashboard; however, resetting the codes does not address the underlying issues and can in worst-case scenarios even lead to engine breakage where the source issue is serious and left unattended for long periods.
The bypass ratio (BPR) of a turbofan engine is the ratio between the mass flow rate of the bypass stream to the mass flow rate entering the core. [1] A 10:1 bypass ratio, for example, means that 10 kg of air passes through the bypass duct for every 1 kg of air passing through the core.
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum ...

The two-shaft turbofan has a high-pressure core from the PS-12 with an eight-stage compressor and a two-stage turbine, and four low-pressure stages. The high-bypass engine does not employ an exhaust mixer, fuel burn should be reduced by 10–15% from the CFM International CFM56 and it could power an upgraded Tupolev Tu-204. [citation needed]
A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.
The TF41 was jointly developed by Allison Engine Company and Rolls-Royce from the latter's RB.168-25R Spey. [1] Allison manufactured the TF41 under license, while Rolls-Royce supplied parts common to existing Speys. [2]
