Analysis of Knocking Characteristic in Dual Fuel Engine - the Effects on Diethyl Ether [PDF]
INCAS Bulletin, 2021 In Diesel engines, where fuel is pumped into highly compressed air towards the end of the compression cycle, knocking is more or less unavoidable. By this time there is already a quantity of fuel in the combustion chamber which will first burn in areas ...
