The search for alternative fuels that can limit the use of traditional fossil to power internal combustion engines is one main tasks faced by both modern automotive industry and energy industry. This paper presents experimental tests a compression ignition engine, in which conventional fuel, i.e., diesel, was partially replaced with propyl alcohol, renewable biofuel. Studies on co-combustion di...

Reactivity control compression ignition engines illustrated suitable abilities in emission reduction beside high thermal efficiency. In this research, nine various direct fuel injection strategies were studied numerically: three cases with single strategy and six split different start of (SOI). all simulated cases, equivalence ratio kept constant (i.e., 0.3). Among strategies, showed higher IME...

Abstract Although direct measurements of the fuel injection pressure and travel injector needle in conjunction with valve train mechanism timing can provide complete diagnostic information about technical conditions systems, this requires installation sensors other equipment directly into which is possible within research laboratories but generally forbidden during operation ship. Malfunctions ...

In the present study, a computational fluid dynamics (CFD) method have been utilized to investigate the effects of exhaust gas recirculation (EGR) and initial charge pressure by means of using a supercharger on the emissions and performance of a SI engine. This engine is fueled separately by gasoline and two potential alternative fuels, hydrogen and ethanol. The results of simulation are compar...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

In this paper, a numerical study is performed to provide the combustion and emission characteristics resulting from fuel-reactivity controlled compression ignition (RCCI) combustion mode in a heavy-duty, single-cylinder diesel engine with gasoline and diesel fuels. In RCCI strategy in-cylinder fuel blending is used to develop fuel reactivity gradients in the combustion chamber that result in a ...

Up to 136 laboratories participated in a joint effort to assess the trueness of routine measurements for 14 serum components. An unmodified, fresh-frozen human serum ("IMEP-17 Material 1"), produced for an international inter-laboratory comparison, served as the "master material". The serum had assigned values of the highest available metrological quality, and is assumed to involve no or neglig...

The addition of hydrogen peroxide and steam to a hydrogen-fuelled HCCI engine was investigated at various fuel lean conditions (ϕeff = 0.2–0.6) compression ratios (15–20) using 0-dimensional numerical model. use as an ignition promoter demonstrated increased IMEP (16%–39%), thermal efficiency (up 2%), reduced NOx (50%–76%) when compared the conventional method intake charge heating. When used p...
