CVU injectors differ from other types of fuel injectors in that they use a piston to control the flow of fuel. The piston is moved up and down by a camshaft, and the movement of the piston creates a constant volume of fuel. This constant volume of fuel is then used to create a pressure differential, which is used to inject the fuel into the combustion chamber.
CVU injectors are known for their high precision and durability. They are also able to withstand high pressures, which makes them ideal for use in diesel engines. However, CVU injectors are also more expensive than other types of fuel injectors.
Overall, CVU fuel injectors are a reliable and efficient type of fuel injector that is commonly used in diesel engines.
