Requirements for Alkylate-based Petrol

Heavy demands are placed on alkylate-based petrols. The specifications laid down by the KWF board of trustees for forest work and forestry technology (Kuratorium für Waldarbeit und Forsttechnik) and those of the Swedish standard SS 155461:2017 serve as the limiting values of 2 and 4-stroke special fuels. These limiting values differ only minimally.

The Difference Between Alkylate-based Petrol and Conventional Petrol

Alkylate-based petrol is intended for use in power tools. For such fuels, the requirements are higher than for petrol intended to fuel vehicles in terms of both operational and external environmental properties. Alkylate-based petrol is not intended for use in road vehicles.

Alkylate-based petrol should be used whenever people come into direct contact with exhaust fumes, as the fumes from such petrol contains up to 99% fewer harmful hydrocarbons. It consists almost entirely of paraffin oils and contains only very small amounts of olefins and aromatics - less than 1% according to the specifications of the KWF and the Swedish standard SS 155461:2017. The sulphur and benzene content is also very low. The proportion of carcinogenic and mutagenic substances, or compounds toxic to reproduction in alkylate-based petrol is therefore much lower than in conventional petrol, making it much better for health and the environment.

Engine performance can also be sustainably increased with alkylate-based petrol, since the clean combustion prevents deposits from forming and thus reduces wear.

The density of alkylate-based petrol is lower than that of conventional petrol. It is therefore advisable to check the mixture control setting in the carburettor and, if necessary, in the fuel injection before using alkylate-based petrol. It should be adjusted if necessary (set it richer) in order to prevent starting difficulties and/or misfiring.
