FAQ:

Q: What is a CO2 injection system?

A: WHAT ABOUT PRESSURIZED SYSTEMS? A pressurized CO2 injection system consists of a cylinder of CO2 under pressure with a regulator screwed on top that allows the CO2 to flow out of the tank at a controlled rate.

Q: What does low carbon dioxide mean in a blood test?

A: What does it mean if your Carbon Dioxide (CO2) result is too low? A low level of bicarbonate in the blood combined with a low pH (less than 7.4) is a condition called metabolic acidosis. Some common causes include: kidney failure, liver failure, severe diarrhea, lactic acidosis, seizures, cancer, prolonged lack of oxygen, and diabetic ketoacidosis.

Q: What is a cylinder injector?

A: The injectors through which the fuel is sprayed are screwed, nozzle-first, into either the inlet manifold or the cylinder head and are angled so that the spray of fuel is fired towards the inlet valve . The injectors are one of two types, depending on the injection system.

Q: What is a chemical injector?

A: The chemical injector relies on the venturi nozzle to create a high pressure, fast stream of water inside the injector body. This nozzle must be properly sized to create the venturi action. The proper sized venturi nozzle will reduce the flow of water leaving the injector slightly, while allowing chemical to be injected.
