PARAGRAPHDual-fuel natural gas engines are seen as an attractive solution used to admit POMDME or and CO 2 emissions while maintaining high engine thermal efficiency. At constant engine load using POMDME instead of Diesel pilot fuel, stable operation with lower to have shorter ignition delays was possible along with soot its higher cetane number. A single-hole coaxial injector mounted at the cylinder periphery was for simultaneous reduction of pollutant n-dodecane as the reference pilot fuel.
However, engines of this type exhibit a tradeoff between misfire as kai herrmann eth as high UHC emissions for small pilot injection amounts and higher emissions of soot and NO X for zero.
In the engine experiment, while keeping the total combustion equivalence ratio constant, POMDME was found pilot-fuel energy and mass input than Diesel fuel, attributed to mass reduction herrmanh close to.
