“…Dual fuel engines have been pursued for several decades [11][12][13][14][15][16][17][18][19][20][21][22], particularly with natural gas as the primary fuel, with the main intention of improving exhaust emissions while maintaining diesel-like FCEs. In dual fuel combustion, an easily auto-ignitable high-cetane fuel (e.g., diesel) is used to ignite an autoignition-resistant low-cetane primary fuel (e.g., methane).…”

Diesel-ignited propane dual fuel low temperature combustion was characterized in a singlecylinder research engine (SCRE) at constant values of indicated mean effective pressure (IMEP of 5.1 bar), engine speed (1500 rpm), and propane energy substitution (PES = 80%). The effects of three important engine parameters (start of injection (SOI) of diesel fuel, common-rail pressure (Prail) for diesel injection, and boost pressure (Pin)) on engine performance, combustion, and emissions were examined. As SOI was advanced from 355 absolute crank angle degrees (CAD) (or 5° BTDC) to 280 CAD for constant Prail = 500 bar and Pin = 1.5 bar, the apparent heat release rate (AHRR) profiles changed from a two-stage, "diesel-like" combustion process to a smooth, "Gaussian-like," single-stage combustion process, that was representative of more homogeneous combustion. In addition, with SOI advancement, the combustion phasing (CA50) was initially advanced but eventually occurred later for very early SOIs. Indicated-specific emissions of oxides of nitrogen (ISNOx) were reduced to about 0.12 g/kWh for SOIs advanced beyond 310 CAD while maintaining high indicated fuel conversion efficiencies (IFCEs). While smoke emissions were below 0.1 FSN for all conditions tested in this study, indicated-specific hydrocarbon (ISHC) and

In the dual fuel engine, much of the energy release comes from the combustion of the gaseous fuel and only a small amount of diesel liquid fuel provides ignition through timed cylinder injection. Such operation with optimum conversion methods has the potential to provide operational characteristics that are comparable or superior to those of the corresponding diesel or spark ignition engines. These characteristics may be realized only if sufficiently effective measures can be ensured both for the avoidance of knock, usually at high loads, and incomplete gaseous fuel utilization at relatively light loads. To overcome these problems associated with the operation of dual fuel engines over a wide range of fuels and their mixtures, better control of the relatively complex processes of combustion is essential. Both experimental and analytical modeling procedures for effecting optimum improvements to the combustion process are described.
