Trends of Air Fuel Ratio on Engine Performance of Four Cylinder Direct Injection Hydrogen Fueled Engine
The present study focuses on the effect of air-fuel ratio on the performance of four cylinder hydrogen fueled direct injection internal combustion engine. GT-Power was utilized to develop the model for direct injection engine. Air-fuel ratio was varied from rich limit to a lean limit. The rotational speed of the engine was varied from 1250 to 4500 rpm. The acquired results shown that the air fu...
متن کاملEffects of Air Fuel Ratio and Injection Timing on Performance for Four-Cylinder Direct Injection Hydrogen Fueled Engine
In this study, the influence air fuel ratio and injection timing on the engine performance of 4-cylinder direct injection hydrogen fueled engine was investigated. The effect of air fuel ratio (AFR) and engine speed on optimum injection timing is presented. The 4-cylinder direct injection hydrogen engine model was developed utilizing the GTPower commercial software. This model employed one dimen...
متن کاملInfluence of Engine Speed and Injection Timings on In-cylinder Heat Transfer for Port Injection Hydrogen Fueled Engine
The overall heat transfer process within the in-cylinder for port injection hydrogen fueled internal combustion engine (H2ICE) has been investigated through simulation, while the experimental data has been utilized for validation purpose of the adopted numerical model. One-dimensional gas dynamics was used to describe the flow and heat transfer in the components of the engine model. The engine ...
متن کاملExperimental Study of Hydrogen Addition Impact on Emissions and Performance of a Natural Gas Fueled Engine
Hydrogen is seen as one of the important energy carriers of the future with potential to reduce local as well as global warming. The main by-product of the combustion of hydrogen in air is water vapor and trace quantities of oxides of nitrogen. An experiment was conducted to study the impact of hydrogen/natural gas blends on performance, thermodynamic efficiency and exhaust gas emissions in ...
