Özet
The engine's power stroke involves injecting LN2 into the cylinder at the top dead centre, allowing nitrogen and air gas to escape. This process, without combustion, overcomes engine friction losses, enabling intake, compression, and output power. Previous studies have focused on improving diesel engine efficiency by adding materials like hydrogen, NO2, clean gasoline, ammonia, LN2, NO, and NOX and altering engine design and spark plugs. This study explores the potential benefits of liquid nitrogen-fuelled automobile engines despite their past inefficiency and similarity to compressed-air engines due to energy waste. The study underscores the potential of nitrogen gas addition in improving the cleanliness and efficiency of diesel engines, paving the way for further research and advancements. Uses CFD simulations to analyze the impact of nitrogen gas concentration on combustion effectiveness, emissions, and performance metrics of a compression-ignition diesel engine, explicitly focusing on nitrogen oxide and particulate matter emissions and their influence on mixture flow velocity. The addition of nitrogen gas significantly impacts combustion dynamics, altering temperature and pressure patterns. The mass flow rate and velocity are positively correlated, and the crankshaft deforms more rapidly with engine rotational speed. Nitrogen gas concentrations affect deformation and pressure, with higher values observed at 1800 RPM and 2200 RPM. The combustion process can be enhanced by adding hydrogen concentrations, changing engine shapes and designs, or using different fuel types. Nitrogen gas concentrations inversely relate to temperature, with higher concentrations causing lower temperatures, which is consistent with nitrogen gas's primary role in reducing engine temperature. Nitrogen gas concentration is linked to pressure gradients.
