Abstract
This work presents an ethanol injection system for diesel engine air intake pipe in order to evaluate its effects on mechanical performance for different energy fraction rates. The equipment measures the machine speed, fuel consumption, calculates the replacement fraction and returns parameters such as start point and active injection time synchronized with diesel injection pulse. The system evaluation was performed on a test bench engine. The speed used in the tests was 1800 rpm and the evaluation loads were 60 Nm and 120 Nm. The tests allowed verify the injection point in the cylinders, substitution energy fraction, torque increasing, temperatures, fuel specific consumption and thermal efficiency.
