... of hydrogen as in situ dual fuel solution to counter the conflicting emission and performance requirements of contemporary diesel engines made to operate under EGR. The unique combustion properties of hydrogen (see supplemental Table S-1 [( 67 )]) make it an ideal choice for its use in compression...

... that current diesel engines emit low levels of N 2 O [( 17 18 19 )]. However, the N 2 O emissions of HCCI engines have not been reported extensively. As described in the literature [( 8 9 10 11 12 )], the nitrous oxide (N 2 O) intermediate route is initiated mainly by the reactions O + N 2  + M ↔...

... such as injection delay and ignition characteristics. The effects of fuel injection timing, which can compensate for these changes, on the performance and emissions in a single cylinder air-cooled diesel engine at partial loads using canola methyl ester and its blends with diesel are presented in this study...

...Seung Hyun Yoon; Su Han Park; Hyun Kyu Suh; Chang Sik Lee An experimental investigation was performed to analyze the effects of biodiesel-ethanol blended fuel spray on the combustion, and exhaust emission characteristics in a single cylinder common-rail diesel engine. In order to analyze...

... to be 89 g / cm 3 and 4.83 mm 2 / s , respectively. Studies on engine performance were conducted using a Prony brake internal combustion (IC) diesel engine using various blending ratios of biodiesel with commercial diesel. The fuel blends were evaluated for parameters such as speed of engine, fuel...

...Murari Mohon Roy This study investigated the effect of fuel injection timing and injection pressure on combustion and odorous emissions in a direct injection diesel engine. Injection timings from 15 deg before top dead center (BTDC) to top dead center (TDC) and injection pressures from 20 MPa...

...Talal F. Yusaf Performance and emission testing for a single cylinder four-stroke diesel engine have been experimentally performed to determine the optimum operation conditions for this engine when it is used as a hybrid power unit. The studied operation parameters included brake specific fuel...

... presents the advanced (injection) low pilot ignition natural gas (ALPING) engine as a viable, efficient, and low emission alternative to conventional diesel engines, and discusses further efficiency improvements to the base ALPING engine using organic rankine cycles (ORC) as bottoming cycles. The ALPING...

...Christopher Simoson; John Wagner, Ph.D. PE Diesel engines are critical in fulfilling transportation and mechanical/electrical power generation needs throughout the world. The engine’s combustion by-products spawn health and environmental concerns, so there is a responsibility to develop emission...

...Murari Mohon Roy This study investigated normal heptane ( N -heptane)-diesel combustion and odorous emissions in a direct injection diesel engine during and after engine warmup at idling. The odor is a little worse with N -heptane and blends than that of diesel fuel due to overleaning...

...., the aldehydes and unburned fuel. Not only are the model results consistent with actual findings, they also support a method for addressing causes of off-load inefficiency and engine failures due to engine oil dilution with fuel. 03 12 2006 26 07 2007 biofuel combustion diesel engines...

...Murari Mohon Roy Direct injection (DI) diesel engines emit a far more disagreeable exhaust odor than gasoline engines, especially at low temperatures and at idling. There is no proper system of odor reduction in these conditions in DI diesel engines. This study investigated a charcoal-adsorption...

... movers include stoichiometric spark-ignited (SI) engines, lean burn SI engines, diesel engines, microturbines, and fuel cells. The investigated option, HCCI engines, is a relatively new type of engine that has some fundamental differences with respect to other prime movers. The prime movers are compared...
