چکیده انگلیسی
This study deals with the effect of water addition on enhancement of maximum hydrogen energy share in a compression ignition engine (7.4Â kW rated power at 1500Â rpm) under dual fuel mode. The specific water consumption (SWC) was varied from 130 to 480Â g/kWÂ h in step of 70Â g/kWÂ h using manifold and port injection methods. Subsequently, the combined effect of reduction of compression ratio (CR) of the engine (from 19.5:1 (base) to 16.5:1 and 15.4:1) along with water addition on further enhancement of hydrogen energy share is investigated. The hydrogen energy share was limited to 18.8% with conventional dual fuel mode due to knocking. However, the energy share increased to 66.5% with water addition (maximum SWC: 480Â g/kWÂ h), and 79% with combined control strategies (SWC of 340Â g/kWÂ h and CR reduction to 16.5:1). Thermal efficiency of the engine under water added dual fuel mode is higher than base diesel mode (single fuel mode), but it is lower than the conventional dual fuel mode without water. The efficiency of the engine with reduced CR and water addition is lower than the conventional dual fuel mode, however at the CR of 16.5:1 and SWC of 340Â g/kWÂ h, the efficiency is comparable with base diesel mode efficiency. Hydrocarbon, carbon monoxide, smoke, and oxides of nitrogen emissions of the engine with water addition (340Â g/kWÂ h) and CR reduction (to 16.5:1) decreased significantly as compared to base diesel mode, but slightly higher than conventional dual fuel mode.
