Book EXPERIMENTAL AND COMPUTATIONAL INVESTIGATION OF DUAL FUEL DIESEL NATURAL GAS RCCI COMBUSTION IN A HEAVY DUTY DIESEL ENGINE

Download or read book EXPERIMENTAL AND COMPUTATIONAL INVESTIGATION OF DUAL FUEL DIESEL NATURAL GAS RCCI COMBUSTION IN A HEAVY DUTY DIESEL ENGINE written by and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Among the various alternative fuels, natural gas is considered as a leading candidate for heavy-duty applications due to its availability and applicability in conventional internal combustion diesel engines. Compared to their diesel counterparts natural gas fueled spark-ignited engines have a lower power density, reduced low-end torque capability, limited altitude performance, and ammonia emissions downstream of the three-way catalyst. The dual fuel diesel/natural gas engine does not suffer with the performance limitations of the spark-ignited concept due to the flexibility of switching between different fueling modes. Considerable research has already been conducted to understand the combustion behavior of dual fuel diesel/natural gas engines. As reported by most researchers, the major difficulty with dual fuel operation is the challenge of providing high levels of natural gas substitution, especially at low and medium loads. In this study extensive experimental and simulation studies were conducted to understand the combustion behavior of a heavy-duty diesel engine when operated with compressed natural gas (CNG) in a dual fuel regime. In one of the experimental studies, conducted on a 13 liter heavy-duty six cylinder diesel engine with a compression ratio of 16.7:1, it was found that at part loads high levels of CNG substitution could be achieved along with very low NOx and PM emissions by applying reactivity controlled compression ignition (RCCI) combustion. When compared to the diesel-only baseline, a 75% reduction in both NOx and PM emissions was observed at a 5 bar BMEP load point along with comparable fuel consumption values. Further experimental studies conducted on the 13 liter heavy-duty six cylinder diesel engine have shown that RCCI combustion targeting low NOx emissions becomes progressively difficult to control as the load is increased at a given speed or the speed is reduced at a given load. To overcome these challenges a number of simulation studies were conducted to quantify the in-cylinder conditions that are needed at high loads and low to medium engine speeds to effectively control low NOx RCCI combustion. A number of design parameters were analyzed in this study including exhaust gas recirculation (EGR) rate, CNG substitution, injection strategy, fuel injection pressure, fuel spray angle and compression ratio. The study revealed that lowering the compression ratio was very effective in controlling low NOx RCCI combustion. By lowering the base compression ratio by 4 points, to 12.7:1, a low NOx RCCI combustion was achieved at both 12 bar and 20 bar BMEP load points. The NOx emissions were reduced by 75% at 12 bar BMEP while fuel consumption was improved by 5.5%. For the 20 BMEP case, a 2% improvement in fuel consumption was achieved with an 87.5% reduction in NOx emissions. At both load points low PM emissions were observed with RCCI combustion. A low NOx RCCI combustion system has multiple advantages over other combustion approaches, these include; significantly lower NOx and PM emission which allows a reduction in aftertreatment cost and packaging requirements along with application of higher CNG substitution rates resulting in reduced CO2 emissions.

Book COMBUSTION DEVELOPMENT OF A HIGH EFFICIENCY DIESEL MICRO PILOT NATURAL GAS ENGINE

Download or read book COMBUSTION DEVELOPMENT OF A HIGH EFFICIENCY DIESEL MICRO PILOT NATURAL GAS ENGINE written by and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Dual fuel engine operation with premixed natural gas as the main fuel and diesel pilot ignition has been gaining interest among research and industry as natural gas is among the most promising existing alternative fuels. The dual fuel engine performance has been shown to equal and sometimes, depending on operating conditions, better the performance and efficiency of the diesel engine. Along with its advantages on the combustion high efficiency, diesel-like performance, and emissions of NOx and particulate matter reduction, some disadvantages are brought by the application of such operation. At light load conditions, there is an increase in CO and HC emissions, low fuel efficiency and combustion stability. While operating at higher loads, the dual fuel engine performance showed to be limited by combustion knock. This effectively reduces the maximum break mean effective pressure (BMEP) the engine can output when compared to a diesel engine. Although combustion knock is well defined in SI and diesel engines, dual fuel knock characterization still needs more investigation. This project centers on developing a fuel system for a diesel engine conversion to dual fuel to deliver high load and high efficiency. The selected engine has been converted to the dual fuel operation and dual fuel combustion has been demonstrated. After achieving the project goal of a high load and high efficiency dual fuel engine, the combustion knock in dual fuel operation will be characterized and a method for detection and intensity calculation will be modeled. The characterization will also be compared to spark ignition (SI) and reactivity-controlled compression ignition (RCCI) operating engines.
