What are the technical requirements for Diesel A that must be taken into account, and why?

The cetane number, water and sediment content, low temperature performance and oxidation stability are the most important characteristics that make it possible to determine the quality level of a fuel.

Firstly, the cetane number gives us an assessment of the fuel ignition capacity in an engine, the most significant characteristic in relation to low temperature ignition.

The cetane number must meet the minimum recommendations of engine manufacturers for each type of service. A higher cetane number than required does not improve the efficiency or running of the engine. Currently, the specification for the cetane number is 51 minimum.

Water and sediment content is an important characteristic because these contaminants can contribute to clogging filters and causing damage to the injection system.

Running at low temperatures is measured by the fuel's capacity to flow and be pumped through the filter system without causing obstruction by the presence of paraffin compounds forming at low temperatures. This diesel performance at low temperatures can be estimated by determining the point of obstruction of the cold filter for which it is specified in winter at a maximum of -10°C.

Finally, oxidation stability measures the tendency of diesel fuel to form gums and sediments derived from oxidation in the presence of air. Diesels with low oxidation stability contain insolubles that can obstruct filters, deform deposits in the combustion chamber and damage components of the injection system.
