Abstract

This paper presents the effect of engine performance by water injection charged air cooling. Water was injected into the intake manifold with different flowrate in a turbocharged spark ignition engine. The simulation was done on a validated engine modelling using GT-Power simulation that was based on a 1.6L turbocharged CamPro CFE engine. Two injectors were used to inject the water into the intake manifold. The addition of water injection shows potential to improve the engine operation characteristics. Improvement of brake torque as much as 19% and brake power as much as 10% have proven that the charged air cooling has improved the turbocharged engine. In this this study, the charged air intake raises the air density in the combustion chamber and has improved the brake specific fuel consumption as much as 23%. With the introduction of water to the upstream of the engine operation, the cooling effect does assist the engine to improve.
