“…Further, the increase in interlayer spacing of PCP was observed in case of detergent‐diesel fuel. Kim et al 10 compared the impacts of lube oil with and without additives on the exhaust emission of a diesel engine. The additives‐based lubricant indicated a decrease in total hydrocarbon and CO emissions while an increment in NO x emission due to the variation in lubricant composition and viscosity levels.…”

In recent years, nanoparticles have attracted researchers attention due to its wear and friction reduction characteristics in lubricating oil. Hence, it is of utmost importance to consider nanoparticles additive in the lube oil and study its impact on the tribological and performance characteristics of mechanical systems. Therefore, this paper intends to explore the impact of conventional and hexagonal boron nitride (hBN) nanoparticles‐based lubricant on the wear of engine components, performance, and emission characteristics of a diesel engine. The different concentration namely, 0.5 wt.%, 0.75 wt.%, and 1 wt.% BN‐based nanofluids were formulated. The formulated nanofluids were characterized by UV‐spectroscopy and differential scanning calorimetry (DSC) for dispersion and heat capacity analyses respectively. From the characterization results, 1wt.% BN nanofluid was found stable and well dispersed and therefore, considered for further experimental analysis. The outcomes of the present study revealed that 1 wt.% BN‐based nanofluid shown better anti‐wear properties and improvement in performance, emission characteristics of the diesel engine. The obtained results will be useful for the lubricant industry to think toward formulating nanoparticles‐based lubricating oil.

“…There are evidences suggesting that nucleation of soluble organic fraction (SOF) is promoted through the turbine [71]. A large share of the SOF is usually related to lubricant oil [46,72,73]; namely, lubricant oil components can represent up to the 80% of the SOF [74]. It is noteworthy that lubricant oil can cause the behavior observed downstream of the turbine in more than one way.…”

Evolution of Soot Particle Number, Mass and Size Distribution along the Exhaust Line of a Heavy-Duty Engine Fueled with Compressed Natural Gas

An experimental study has been conducted to provide a characterization of the transformations that particle size distributions and the number density of soot particles can encounter along the exhaust line of a modern EURO VI compliant heavy-duty engine, fueled with compressed natural gas. Being aware of the particles history in the exhausts can be of utmost importance to understand soot formation and oxidation dynamics, so that, new strategies for further reducing these emissions can be formulated and present and future regulations met. To this purpose, particle samples were collected from several points along the exhaust pipe, namely upstream and downstream of each device the exhaust gases interact with. The engine was turbocharged and equipped with a two-stage after-treatment system. The measurements were carried out in steady conditions while the engine operated in stoichiometric conditions. Particle emissions were measured using a fast-response particle size spectrometer (DMS500) so that size information was analyzed in the range between 5 and 1000 nm. Particle mass information was derived from size distribution data using a correlation available in the literature. The reported results provide more insight on the particle emission process related to natural gas engines and, in particular, point out the effects that the turbine and the after-treatment devices produce on soot particles. Furthermore, the reported observations suggest that soot particles might not derive only from the fuel, namely, external sources, such as lubricant oil, might have a relevant role in soot formation.

In high-pressure common rail fuel injection system, fuel pressure wave propagates back and forth in the system during fuel injection, and the cycle fuel injection volume is affected by the fluctuation of fuel injection pressure. Therefore, to reduce the influence of pressure fluctuation on the cycle fuel injection volume fluctuation, it is of great theoretical significance to analyze the mechanism of pressure fluctuation and its influence law. In this chapter, the dynamic pressure fluctuation characteristics of the high-pressure common rail fuel injection system are analyzed based on the injector inlet pressure, and experimental research and theoretical analysis are carried out for the time domain and frequency domain characteristics of injector inlet pressure fluctuation, aiming at revealing the pressure fluctuation mechanism and its influence law, and providing theoretical support for improving the control accuracy of multiple injection cycle fuel injection volume.
