Description

The invention relates to mechanical engineering, in particular to engine building, in particular to devices for adding water to a fuel-air mixture of an internal combustion engine.

A device is known for the addition of water to the air-fuel mixture of an internal combustion engine, comprising a spray gun, an electric variable displacement pump, a pipeline and a container with an additive (water) 1.

A disadvantage of the known power system is that. that it is not always possible to provide the optimum amount of water supplied to the engine, especially at low temperatures of the intake air due to condensation of water.

The closest in technical essence and the achieved result to the proposed technical solution is a device for adding water to the fuel-air mixture of an internal combustion engine, comprising a water supply line with a water evaporator, an ionizer connected to the engine inlet pipe and provided with positive and negative electrodes connected to the main power supply, and a throttle for regulating the vacuum in the intake pipe, while the evaporator is made in the form of a snake ka and is located around the exhaust pipe of the engine 2.

The device supplies ionized water vapor to the engine inlet to reduce engine fuel consumption and exhaust emissions.

A disadvantage of the known device is its complexity. In addition, the presence of a throttle valve creates additional resistance at the inlet, not ensuring optimal water supply in all modes, and limits its use in diesel engines. The ionizer in the form of a chamber equipped with electrodes ionizes only water, limiting the efficiency of processing the mixture with an electric field. The presence of positively charged water ions contributes to their intense deposition on the walls of the inlet pipe of the internal combustion engine having a negative potential,

The aim of the invention is to simplify the design, improve the accuracy of dosing of the water supply, increase the efficiency of processing the mixture by providing ionization of the air of water, thereby reducing fuel consumption

engine exhaust emissions

This goal is achieved in that in a device for adding water to the air-fuel mixture of an internal combustion engine, comprising a water supply line with a water evaporator, an ionizer in communication with the engine intake pipe and provided with a positive and

With negative electrodes connected to the main power source, the inlet pipe is equipped with a dielectric nozzle, the positive electrode is made in the form of a cylinder placed in the dielectric nozzle 5, the negative electrode is in the form of a curved tubular water atomizer, and a pump with an electric drive from an additional source of power is installed in the water supply line current associated with the automatic control system, and as the main power source used power source direct current

auto-adjusting system 15. It has the role of electric diffuser. method- The power is supplied to a power source 14 of a very strong dissociation of constant current particles, which causes a pump 13 to act under high voltage. The pump delivers water from a direct current, which leads to a uniform tank 6 through the filter 10 into the water supply 9 and 5 of the cylinder water distribution evaporator 8, where the water is overheated and the internal combustion engine. An accurate cut of the steam line 7 and the atomizer feeds water, depending on the mode, into the ionizer. Under the influence of strong electric operation of the internal combustion engine, the negatively charged field provides the pump 13 with electrically water particles rushing to the periphery, 10 from the power supply 14 of the constant positive electrode 3 and, displaced from the current, equipped with an automatic ionized air through the inlet regulation, pipeline 1 of the internal engine - Bench research of the engine
