ECU

TLDI uses ECU to control factors such as fuel injection amount, injection timing and ignition timing to the best suited
conditions based on the information from the sensors.Moreover, the TLDI achieves lean combustion through stratified
charge in the low engine speed range, and highly efficient combustion through electronic control of premixed charge that
provides homogeneous fuel distribution in the combustion chamber in the high speed range.
