What methods are available for mixing additive with gas?

Methods of “F2-21 ee Fuel“ additive blending with gas.

«Piped», compressed and liquefied natural gas - the additive is injected into the fuel gas flow after the control mechanism in the amount determined by fuel gas and additive density ratio, and additive concentration.

In a constructive way:
1. Additive consumption is ranging from 20 to 150 milliliter per hour.
1.1. The additive can be injected into the vacuum space inside the combustion chamber or engine intake system.
1.2. The additive can be injected into the high-pressure area of engine cylinder. High pressure pumps and piezo actuated unit injectors of diesel engines with fuel consumption of up to 0.5 liter per hour can be used.
2. Additive consumption is ranging from 150 to 250 and from 250 to 500 milliliter per hour.
2.1. The additive can be injected into the vacuum space inside the combustion chamber or engine intake system. The pumps and piezo actuated unit injectors of diesel engines can be used.
2.2. The additive can be injected into the high-pressure area of engine cylinder. The pumps and piezo actuated unit injectors of diesel engines can be used.
3. Additive consumption is more than 1 liter per hour. It can be injected by high-pressure pumps and injectors.
