Performance Combustion and Emission Characteristics of a

Polyoxymethylene dimethyl ethers (PODEn) stand for the mixtures of ethers with the formula of CH 3O(CH 2O)nCH 3 Compared with DME PODEn have the similar oxygen content but lower vapor pressure and higher cetane number and are usually in liquid form Among PODEn PODE 2 does not fulfill the security criterion due to its low flash point [7] and if n is higher than 5
