Performance Evaluation and Emissions improving of Turbocharged DI Diesel Engine with Exhaust Gas Recirculation (EGR)
Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...
متن کاملLaboratory Study on Influence of Air Duct Throttling on Exhaust Gas Composition in Marine Four-stroke Diesel Engine
Presented paper shows results of laboratory tests on the relationship between the throttling of a cross area of an air intake duct and the composition of exhaust gas from the marine engine. The object of research is a laboratory four-stroke diesel engine, worked with a load from 50kW to 250kW at a constant speed. During the laboratory, tests over 50 parameters were measured of the engine with t...
متن کاملPerformance and Exhaust Gas Emissions Analysis of Direct Injection Cng-diesel Dual Fuel Engine
Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...
متن کاملLocation Isolability of Intake and Exhaust Manifold Leaks in a Turbocharged Diesel Engine with Exhaust Gas Recirculation
An investigation into the isolability of the location of intake and exhaust manifold leaks in heavy duty diesel engines is presented. In particular, established fault detection and isolation (FDI) methods are explored to assess their utility in successfully determining the location of a leak within the air path of an engine equipped with exhaust gas recirculation and an asymmetric twin-scroll t...
