FADEC is the acronym for Full Authority Digital Engine Control. It is a system consisting of a digital computer (called EEC /Electronic Engine Control/ or ECU /Electronic Control Unit/) and its related accessories which control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines, their primary difference due to the different ways of controlling the engines.

Electronics' superior accuracy led to early generation analogue electronic control first used in Concorde's Rolls-Royce Olympus 5 ....etc

The evolutionary engine and the mind machine:
A design-based study of adaptive change

by

Christopher Complin




Abstract

The objectives of this thesis are to elucidate adaptive change from a design-stance, provide a detailed examination of the concept of evolvability and computationally model agents which undergo both genetic and cultural evolution. Using Sloman’s (1994) design-based methodology, Darwinian evolution by natural selection is taken as a starting point. The concept of adaptive change is ....etc

The stratified charge engine is a type of internal-combustion engine, similar in some ways to the Diesel cycle, but running on normal gasoline. The name refers to the layering of fuel/air mixture, the charge inside the cylinder.

In a traditional Otto cycle engine the fuel and air are mixed outside the cylinder and are drawn into it during the intake stroke. The air/fuel ratio is kept very close to stoichiometric, which is defined as the exact amount of air necessary for a complete combustion of the fuel. This mixture is easily ignited and bu ....etc

The present day requirement for high performance from a medium power engine has resulted in generally higher maximum crank shaft speeds, typically in the region 5500 ? 6000 rpm. This can be explained by recalling the factors governing the power output of an engine since, if neither piston displacement nor mean effective pressure can be further increased. Then the only other way to raise the maximum power is to permit higher crank shaft speeds. For this reason it becomes increasingly more important to avoid erratic operation of valves. As a resu ....etc

MPFI ( multi point fuel injection system ) Vs CRDI(Common rail direct injection system)

(Actually an open office format. Use open office to open it)
MPFI : mean multi point fuel injection system ie. in petrol engine for gaining more uniform Air Fuel blending fuel is injected at various point in the path of air. this tech is used in light weight car running on petrol. there is also milage improvement due to this.

but in case of DTSI(digital twin spark ignition) : the
engine cylinder consist of two no of spark plu ....etc
