TL;DR: In this article, the effects of blending n-butanol and n-pentanol with biodiesel at 10% and 20% by volume on engine performance and on the physico-chemical characteristics of particulate emissions from a single cylinder, direct injection diesel engine.

TL;DR: In this paper, an ideal thermodynamics model of the exhaust gas compression, water injection at top center, and expansion was used to investigate this modification that effectively recovers waste heat from both the engine coolant and combustion exhaust gas.

TL;DR: In this paper, the results of an experimental investigation of methane-air combustion within a porous medium burner for various equivalence ratios and flow rates are presented, and the results indicate that CO and NOx, emissions increase with flame speed.
Abstract: In this paper, we report the results of an experimental investigation of methane-air combustion within a porous medium burner for various equivalence ratios and flow rates. Measurements of emissions and radiant output are presented. The results indicate that CO and NOx, emissions increase with flame speed. For a given equivalence ratio, however, NOx, emissions are fairly constant over the range of flame speed studied. The radiant output increases but the radiant thermal efficiency decreases with flame speed.

TL;DR: In this article, the performance and emission characteristics of the diesel engine with hydrogen added to the intake air at late diesel-fuel injection timings were investigated and the authors attempted to reduce further NO and smoke emissions by EGR.

TL;DR: In this article, the on-road RCS-E (Rankine cycle system efficiency) is as low as 3.63%, which is less than half of the design RCSE (7.77%) at the rated operating point.
