“…Similar studies with using the chambers: Hemispherical, Straight Sided, Toroidal and Re-entrant Toroidal were conducted by Channappagoudra et al [2] powering the CI engine with the B20 fuel. The best parameters of engine operation and exhaust emission indicators were obtained by using the Re-entrant Toroidal chamber.…”

Modern solutions used in compression-ignition internal combustion engines are quite similar to each other. The use of high-pressure, direct fuel injection results in high combustion rates with controlled exhaust emissions. One of the combustion system quality criteria is to obtain adequately high thermodynamic indicators of the combustion process, which are obtained through, among others, the right combustion chamber geometry. Its shape influences the fuel atomization process, turbulence of fuel dose, evaporation and the combustion process. Optimizing the combustion chamber shape is one of the decisive factors proving the correct execution of the combustion process. This article presents the methodology of choosing the combustion chamber shape (changes of three selected combustion chamber dimensions) by using the optimization methods. Generating multidimensional data while maintaining the correlation structure was performed by using the Latin hypercube method. Chamber optimization was carried out by using the Nelder-Mead method. The combustion chamber shape was optimized for three engine load values (determined by the average indicated pressure) at selected engine operating conditions. The presented method of engine combustion chamber optimization can be used in low and high speed diesel propulsion engines (especially in maritime transport applications).

“…Some engine parts were modified, including the nozzle and piston bowl geometry, then the modified engine was run with varying operational parameters such as injector opening pressure and injection timing. The study reported that an improvement could be achieved with a performance comparable with diesel fuel [10]. Moreover, an engine fueled with B20 does not required alterations in fuel injection time to obtain combustion, performance and emissions comparable to diesel fuel [10].…”

In this study, biodiesel fuel with a ratio of 20% volume (B20) was used on vehicles that are used in common rail injection systems, complying with Euro2 emission regulations. Laboratory and road tests were conducted to evaluate the effects of B20 on performance, emissions and engine components. Using diesel fuel and B20 as reference fuels, tests were conducted using Euro2 vehicle technology to investigate the effects on emissions, fuel consumption, and power. Durability testing was run for travel distances covering 40,000 km under various road and environmental conditions, while vehicle performance and emissions tests were conducted using the ECE R84-03 and ECE R101 test methods, respectively. The results show that B20 has lower CO and hydrocarbon (HC) emissions for every distance travelled, with an average of around 30%. Particulate emission was a bit lower, averaging 3.4% for B20 compared to B0, while NOx was found to slightly increase at around 2% for B20. Due to its lower calorific value, for an average distance traveled, the fuel economy of B20 was around 0.5% higher compared to B0. Furthermore, the maximum power of B20 was 3% lower compared to that of B0 for the entire distance traveled. However, an evaluation of engine components after 40,000 km showed that B20 and B0 were similar. Moreover, vehicles using B20 tend to have a comparable durability of engine components when compared with B0.

“…The performance tests were conducted on diesel engine by using B20 dairy scum biodiesel-diesel blend for different types of combustion chamber geometries at optimum engine operating conditions. It was found that Re-entrant Toroidal Piston Bowl Geometry (RTPBG) resulted in improved performance, combustion and reduced emission characteristics compared to other types of piston bowl geometries [156]. Figure 7 shows the summery of modifications done in fuel injection system.…”

The ever-increasing demand for transport is sustained by internal combustion (IC) engines. The demand for transport energy is large and continuously increasing across the globe. Though there are few alternative options emerging that may eliminate the IC engine, they are in a developing stage, meaning the burden of transportation has to be borne by IC engines until at least the near future. Hence, IC engines continue to be the prime mechanism to sustain transportation in general. However, the scarcity of fossil fuels and its rising prices have forced nations to look for alternate fuels. Biodiesel has been emerged as the replacement of diesel as fuel for diesel engines. The use of biodiesel in the existing diesel engine is not that efficient when it is compared with diesel run engine. Therefore, the biodiesel engine must be suitably improved in its design and developments pertaining to the intake manifold, fuel injection system, combustion chamber and exhaust manifold to get the maximum power output, improved brake thermal efficiency with reduced fuel consumption and exhaust emissions that are compatible with international standards. This paper reviews the efforts put by different researchers in modifying the engine components and systems to develop a diesel engine run on biodiesel for better performance, progressive combustion and improved emissions.
