TL;DR: In this article, an experimental investigation was carried out to study the effect of injection timing, diesel injection pressure, substitution rate of natural gas as well as engine load on the combustion and emission characteristics of an electronically controlled common-rail diesel/natural gas dual fuel engine.
Abstract: An experimental investigation was carried out to study the effect of injection timing, diesel injection pressure, substitution rate of natural gas as well as engine load on the combustion and emission characteristics of an electronically controlled common-rail diesel/natural gas dual fuel engine. The tests were conducted at a fixed engine speed of 1200 r/min, while other parameters were varied in reference to different study purposes. It can be concluded from the experimental results that maximum in-cylinder pressure and maximum heat release rate as well as the combustion noise are generally increased as injection timing advances and injection pressure increases, while decreases at higher substitution rate. Concerning the emission characteristics, THC and CO emissions could be improved by advancing injection timing and increasing diesel injection pressure with penalty on NOx emissions; in addition, THC emissions are significantly increased at higher load and higher substitution rate, while CO emissions reduce considerably with increasing load but tend to be less sensitive to substitution rate; NOx emissions can be mitigated by application of higher substitution rate and get worse as engine load increases.

TL;DR: In this article, an experiment was conducted on a single-cylinder diesel engine with the port fuel injection (PFI) of methanol and the results revealed that, because of the lower cetane number and larger latent evaporation heat value, the ignition timing delayed clearly, the maximum incylinder gas pressure decreased, and the maximum heat release rate increased with the PFI.
Abstract: A large number of published papers reveal that gas-to-liquid (GTL) fuel has the potential for reducing the particulate matter (PM), CO, and hydrocarbon (HC) emissions to a certain degree, and NOx emissions can also be reduced by optimizing the engine parameters or at a larger exhaust gas recirculation (EGR) rate. To reduce the PM and NOx emissions simultaneously on a larger scale, an experiment was conducted of GTL combustion and emissions on a single-cylinder diesel engine with the port fuel injection (PFI) of methanol. The results revealed that, because of the lower cetane number and larger latent evaporation heat value of methanol, the ignition timing delayed clearly, the maximum in-cylinder gas pressure decreased, and the maximum heat release rate increased with the PFI of methanol. At a lower to medium overall equivalence ratio, the maximum in-cylinder gas temperature decreased linearly with the increase of the premixed ratio of methanol. At a large overall equivalence ratio, the maximum gas temperat...

TL;DR: In this paper, a review is made of some of the main problems associated with the use of natural gas, notably methane, in dual fuel engines of the compression ignition diesel type.
Abstract: A review is made of some of the main problems associated with the use of natural gas, notably methane, in dual fuel engines of the compression ignition diesel type. It is shown that such applications represent in principle a very attractive mode for the utilization of the fuel for the production of power generally at relatively high efficiencies and outputs with good exhaust emissions characteristics. Some relevant solutions to the problems outlined are then discussed. Moreover, some further research and development needed in this general area is also outlined.
