“…For the sole purpose of fresh mixture density increase, and so for increasing the amount of fuel aspirated into an internal combustion engine, the indirect water injection seems, at first glance, of a moderated interest, at least when compared to usual forced induction strategies. As a matter of fact, increases of about 15% of brake torques experimentally observed by some authors [14] are then probably not only due to such increase of density, but also to the effect of water addition on the engine cycle itself.…”

Water injection is a well-known efficient way to improve the performance of internal combustion engines. Amazingly, most of previous studies have yet only assess this process in an experimental manner, depriving us of an understanding of its specific influence on different operating phases of the engine -density of the aspirated fresh mixture, work required by the compression stroke, and so on -but also of the possibility to predict its effects if set up on an existing engine. Thanks to a theoretical framework specifically developed, and similar to the one commonly used for the analysis of air conditioning systems, we start in this paper to untangle in a theoretical manner the different consequences of water injection on internal combustion engines. This first study is specifically focused on the fresh mixture density increase, due to the vaporisation of liquid water in the intake manifold. Results show that, in the best scenarios, we cannot expect to increase the amount of fuel finally aspirated into the cylinders by more than 10%. The methodology presented here, as well as the python software specifically developed, can be of a precious help for the optimisation of such process if applied to existing or future engines.

“…The study shows that below 3000rpm the in-cylinder pressure increase to provide more torque to the engine [16]. According to Busuttil et al, the intake temperature change by injecting water in the combustion effect the engine torque by as much as 7% [17]. Higher in-cylinder pressure obtained by the engine produced higher torque.…”

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.

“…Extensive research work has been carried out in the field of water injection in an internal combustion engine. The current project is a cumulative work of these research papers in combination to reduce the overall emissions Busuttil et al [1] experimentally investigated the optimum quantity of water to be injected for a particular engine. The experimentation was done using a combination of injectors and a specially designed circuit Breda et al [2] investigated using CFD analysis the solutions to increase the knock resistance.…”

The Emissions from combustion of fuels such as petrol and diesel in I.C. engines and the particulate matter released have been major part of the air pollution sources, especially in urban areas. It has always been the cause of severe public health issues for so long. A lot of research has been carried out in the field of reduction of these pollutants since diesel engines came into prime use. The Main emissions from a diesel engine are Oxides of Nitrogen (NOx), Carbon Monoxide (CO), Oxides of Sulphur (SOx) and particulate matter (PM). The use of an emulsion of diesel in water as a fuel has been a recent subject of study in this sector. Without compromising on the engine's performance, Water/diesel (W/D) emulsified formulations have evidently reduced the emissions of CO, SOx, NOx and particulate matter (PM) significantly. The depleting amount of Natural resources like natural gas, petroleum oil is evident by the ever escalating prices of crude oil, and is increased by transportation losses viz. leakages and oil spills. The fuel efficiency of the vehicle is the key factor while purchasing new vehicle
