An experimental investigation was conducted on the performance, combustion and knock characteristics of a high compression ratio, lean-burn heavy-duty spark ignition (SI) engine fuelled with n-butane and liquefied methane gas blend. Specifically, some technical adaptations were carried out on the original compression ignition (CI) engine for changing the direct fuel injection system into the electronic...
An experiment was conducted to investigate the effects of methane content in natural gas on combustion and performance of a liquefied natural gas (LNG) heavy-duty engine. Two kinds of LNG with different methane contents (i.e. 93% and 99%), in combination with three compression ratios (i.e. CR11.6, CR14 and CR16) and varied spark timings were tested and compared at various engine speeds. The results...
With the rapid development of EVs (electric vehicles), the integration of PV (photovoltaic) generation with EV charging infrastructure can effectively improve the efficiency of clean energy utilization and carbon emission reduction. How to optimize the capacities of components in the PV-based BSS (battery switch stations) is still unsettled. This paper focuses on the mathematical model of the problem...
In this work, the commercially available diesel fuel (Bu00), butanol(20%)–diesel(80%) (by vol.) (Bu20), butanol(30%)–diesel(70%) (Bu30), and butanol(40%)–diesel (60%) (Bu40) fuels were tested. Experiments were conducted on a high-speed direct injection (DI) diesel engine for passenger-car application for varied loads at two representative engine speeds. The results showed that butanol–diesel blends...
