Universal system for engine control enhancement

Characterization presentation

Prestenters : Ehab Shakour Gaby Shakour

Instructor : Moni Orbach

Historical BackgroundBefore 1970Carburetor & Distributors

1980s till nowECU

Then we cameNew generation ECU

MotivationNowadays:Most ECU’s today aren’t modifiable Expensive , Narrow Range

Our Design: Engine modes: sport , economic, power More engines , more modes , more control

Project goals

Building an Engine-Control-Unit, for power optimization of the engine performance.

The unit controls the plugs and fuel injectors

specifications

Real time systemRead sensors with A to D Analyze and calculate using LUT’sGenerate output with D to A
