Oxides of Nitrogen are the major emission from a diesel engine. It is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of NO is promoted. Various techniques are therefore employed to reduce the NOX emission like EGR, SCR, etc. In this present work a rotating injector is a tec...

Hydrogen is an effective route for achieving zero carbon dioxide emissions, with a contained cost compared to electric powertrains. When considering the conversion of spark ignition (SI) engines H2 fueling, relatively minor changes are required in terms added components. This study looks at possibility converting small-size passenger car powered by turbocharged SI unit. The initial evaluation r...

Presenting the influence of compressed natural gas (CNG) used as alternative fuel on combustion an automotive diesel engine represents main objective this paper. The paper studies brake specific energetic consumption, in-cylinder pressure and rise rate, carbon dioxide, nitrogen oxides, smoke hydrocarbons emissions at 2000 rev/min 40%, 55% 70% load. Low content will determine lower CO 2 all load...

Automobile industries primarily use petroleum-based fuels like petrol and diesel, creating environmental hazards, a high carbon footprint, severe health issues. The world focuses on compressed natural gas (CNG)-based energy solutions developing CNG infrastructures to minimize concerns from fossil fuel. current focus introduce fraction of hydrogen with in the existing fuel system is initiated he...

The improvement of the overall utilization rate compressed natural gas (CNG) engine fuel is basis efficient energy utilization. On foundation heat balance theory internal combustion engines, this study fully considers operation characteristics CNG engines and systematically analyzes distribution different waste under variable working conditions. nonlinear relationship between speed intercooler ...

methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. use of biofuels such as methanol for combustion process is associated with positive environmental impacts. using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. in this paper, methanol was injected into combustion chamber of a ism 370 hd dies...

Turbocharged CNG engines produce high NOx emission due to the fuel type and high combustion temperature. In this research, the effects of lean-burn and waste gate opening pressure threshold on NOx emission are studied theoretically and experimentally at WOT condition as well as 13-mode ECE-R49 test cycle. A code is developed in MATLAB environment for predicting engine NOx and the results are va...
