Performance and NOx Investigation on Diesel Engine using Cold EGR Spiral Tube: A Review

Abstract

Abstractthe world has the same problem to reduce emissions. Based the problem, many technologies invented to reduce the Emission. One of them is EGR (Exhaust Gas Recirculation). EGR is the most simpleNOx reduction by circulating potion of exhaust gas return into the combustion chamber. EGR system is often known by the name the hot EGR where exhaust gas circulation process without cooling system. This new Hot EGR system is designed by the addition of cooling system with air-cooled type. So that the circulating of exhaust gas to be cooled in advance in such that the mass of air increases.This research aims to study the performance and a reduction in NOX of diesel engine with EGR using addition of air cooling system. The experiments were used on diesel engine Yanmar TF 85-MHDI.

Effect of Water Fuel Emulsion on Performance and NOx Emissions of Diesel Engine

“…The technique concerned with introducing water into engine combustion chamber was proposed by Prof. B. Hopkinson in 1913, to make better internal cooling of the gas engine and to increase the engine output. Furthermore, the technique was developed to improve the thermal efficiency and reduce exhaust emissions, or used as the safety fuel [5][6][7][8][9][10][11][12][13][14][15].…”

“…The vapour also eliminates unburnt residual particles and helps the cleaning of engine parts and exhaust system. [5,[30][31][32][33][34][35][36][37][38] With more than 90% of global trade now carried by sea, the shipping industry has played a crucial role in shaping the integrated global economy. It is estimated that if the growth trend of the last 150 years continues, nearly 23 billion tons of cargo that will be transported by ship by 2060, compared to 8.5 billion tones in 2010.…”

“…Figure 3 described the emissions calculation that carried out from a South American perspective for transporting 1000 tons of cargo between Manaus, Brazil and either Buenos Aires, Argentina or Santos, Brazil. For shipping this means that the international rules apply, that is, a maximum fuel sulphur content of 3.5% and, for ships constructed after 2000, tier 1 NOx levels [5] II. METHOD Before the experiment needs to prepare of fuel used for mixing with water.…”

Concept for a LNG Gas Handling System for a Dual Fuel Engine

“…The use of LNG as marine fuel is the proven solution and will contribute to a reduction of these emissions. These reductions will have significant environmental benefits such as improved local air quality, reduced acid rain and contribute to limit global warming [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”
