Mastering Dual-Fuel Combustion

Dual-fuel combustion = A strategy to improve thermal efficiencies of internal combustion engines and reduce emissions Compression ignition engines = Engines that utilize dual-fuel combustion to promote the use of more available gaseous fuels or advanced combustion modes Spark-ignited engines = Engines that implement a dual-fuel combustion strategy to avoid engine knock Engine knock = A condition in engines caused by the air-fuel mixture in the cylinder detonating in more than once place at a time

Improved control of combustion timing = Achieved by varying the proportion of two simultaneously injected fuels Use of advanced combustion modes at high load = Possible because the two injected fuels ignite in succession reducing high peak pressures

Compression ignition engines = Promote the use of more readily available gaseous fuels or more efficient, advanced combustion modes Spark-ignited engines = Use dual-fuel combustion as an alternative approach to avoid engine knock

<p>Simultaneous injection of two fuels = Allows improved control of the combustion timing and use of advanced combustion modes at high load Use of more readily available gaseous fuels = Promoted in compression ignition engines via dual-fuel combustion</p> Signup and view all the answers
