Under the increasingly drastic conditions imposed on motor vehicles, in terms of pollution, manufacturers and researchers are looking for solutions to reduce pollutant emissions, especially emissions of nitrogen oxides (NOx) dissipated in the atmosphere. The problem of polluting emissions in the field of transport is becoming increasingly stringent, the pollution rules are becoming stricter, so there is a general interest in finding solutions to reduce pollutant emissions and fuel consumption. A possible solution to this problem can be achieved by direct or indirect water injection (through the valve port) inside the cylinder of an internal combustion engine. In this paperwork we present the test bench and we analyzed the effect of water injection inside a cylinder of an internal combustion engine. The water injection is made upstream of the throttle valve by single injector mounted on the intake. The injection timing and amount of water injected inside the engine have been controlled by CompactRIO hardware device and in-house algorithm implemented in LabView. The engine used for measurements is a 1.6 liter engine, manufactured by Daewoo Motor Company and for the moment it's running on wasted spark configuration. So in order to have water particles in all the cylinders, the water is injected two times at each rotation of the crankshaft. The main goal of this research was decreasing of nitrogen oxides (NOx) by reducing the combustion chamber temperature.
