ASTM D2699 FREE DOWNLOAD

Varying the compression ratio by manipulating the cylinder height during engine operation produces various levels of knock intensity, making it possible to compare unknown fuels to reference fuels with known octane values. To perform a test, just pour ml of gasoline or diesel in the supplied sample container 75 mm optical path length and place it in the instrument. The ZX is the only NIR analyser which combines all these features with direct measurement, improved portability, user-friendliness and low cost. Already Subscribed to this document.
