Digital Air Pressure Controller For Four Cylinder Engine
For better drivability and better emission, amount of fuel input & air input to engine are most important
parameter. For better injection of fuel and air, supply system of engine should be accurate and appropriate. Electronic Engine
Management is the science of electronically equipping, controlling, correcting and adjusting an engine to maintain top
performance and fuel economy while achieving cleanest possible exhaust spurt, and continuously detecting system defect
(flaw). Due to the demanding of lower emissions, together with the need for better performance, air supply is a very
important factor. This paper mainly explores design of air pressure controller i.e. ECU (Engine control Unit) simulation
board for the application of off board testing and validation of component at manufacturer level. To Control air-fuel in
engine we have engine control unit (ECU), but it is used in vehicle (ON-BOARD TESTING) and not available with air
circulator component manufacturer and vehicle service station. So for testing and validation of component before exporting /
Replacing, designed handheld controller is very useful.
