HiTEC® 46600 Multifunctional Diesel Performance Additive

The DLG QUALITY SEAL for operating equipment and consum­ables encompasses products, which are subjected to extensive testing of their value-determining and advertised characteristics.

The tested criteria and the requirements to be fulfilled are specified by independent commissions and are designed – over and above legal requirements – to prove the product’s fitness for purpose, its advertised characteristics and practical requirements.

Testing contents and requirements are developed further by the responsible specialist departments of the DLG e.V. in line with the applicable legislation, as well as with technical and scientific progress. 

Successful testing is concluded with the assignment of the DLG QUALITY SEAL. The approved products  are then published.

In the course of the development of diesel engines, fuel injection systems have become more and  more complex, the injection pressures higher and the injection nozzle holes in the injectors are smaller,  more precise and more sensitive to dirt and deposits. 

These deposits affect the fuel spray pattern and subsequent combustion becomes less effective.  This reduces engine performance and can also lead to a deterioration in exhaust gas behavior and, in the worst case, to engine damage.

A well-controlled industry ‘Test Fuel’ consistent with fuel used in the industry standard CEC F-098 injector coking test was used to provide an efficient and reproducible method of creating injector deposits. Injector coking deposits in market fuel arise from a range of contaminants and oxidation products that  occur in fuel manufacturing, shipping, and storage. Dissolved zinc from sources such as galvanized fuel tanks or the release of tiny particles from brass connections combined with oxidation products from bio-diesel  can accelerate deposit formation in the nozzle holes in a very short time.

With the HiTEC® 46600 diesel fuel additive deposits on the injector nozzle holes are broken down and new deposits are prevented, reversing the effects on combustion and restoring vehicle performance. Other criteria were not tested.
