Water injection system is used to lower in-cylinder temperatures and burn the air or fuel mixture, which helps to avoid detonation. It is useful in forced induction and internal combustion engines. The system consists of water injector, high pressure pumps and inlet air temperature sensor. A pressure sensor is connected to the inlet manifold. It is engaged when the inlet air temperature is exceeding 40 degrees Celsius. It provides 3D cartography.

Water jet cutting is a powerful variance on the conventional metal cutting tools. By means of high-pressure water jet and some abrasive, munitions can be cut with high speed. Nevertheless it is a relatively safe method as the water cools the metal and possible ignition of the explosive is suppressed. This technique can be utilized on those munitions that cannot be opened by reversed assembly e.g. munitions in bad condition. Water pressures of 400 MPa are commonly used for industrial purposes, although pressure as high as 1400 MPa is possible. The nozzle diameter can vary between 0.05 and 1mm. The outcome is a fine water jet that can cut a narrow groove. Materials for which water jet cutting is used include cardboard, insulating materials, rubber, soft gasket materials, fabrics, plastics, and food produce.

The water jet cutting service operated on the principle of using a granular abrasive medium contained in a high pressure water stream to accomplish its cutting. It cuts faster than wire EDM, and can handle thicker material than most lasers. It has a process where a jet stream of water is forced through a tiny nozzle at a very high pressure. It provides many unique capabilities and advantages that allow the cutting of materials and parts often considered too costly or even impossible with other methods such as laser and die cutting.
