The ADEM A4 electronic control module manages fuel
delivery and airow to get the best performance per liter
(gallon) of fuel used. It provides exible fuel mapping, allowing
the engine to respond quickly to varying application needs.
MEUI Fuel System
Through the use of multiple injection fuel delivery,
combustion chamber temperatures are lower, generating
fewer emissions and optimized fuel efciency. This is
accomplished with the MEUI fuel system, which strikes
the proper balance between the precision of the electronic
control system and the simplicity of mechanically controlled
unit fuel injectors. The result is more productivity and lower
fuel consumption.
