- Summary:
- Early Direct Injection Homogeneous Charge Compression Ignition is one of the clean combustion technologies which reduces the oxides of nitrogen and soot emissions significantly. However, this strategy suffered from drawbacks of fuel spray impingement on cylinder walls, excessive carbon monoxide, and unburnt hydrocarbon emissions, and lower thermal efficiency than conventional diesel combustion in CI engines. A novel attempt has been made in this experimental research work to address the above-said issues by injection of oxy hydrogen gas as a fuel additive to diesel in stationary Compression Ignition engine. This gas was injected into the intake manifold where it premixes with the incoming air. Experiments were conducted at a constant rpm of 1500 and load was varied from 0 to 75%. The diesel was injected by common rail direct injector 45 Before Top Dead Center which ensured an almost homogenous mixture of air, oxy hydrogen gas, and diesel. Due to the presence of hydrogen, the increased flame speed resulted in an increase in peak pressure and heat release rates. This enhanced the Brake Power and Brake Thermal Efficiency. CO and HC emissions were reduced due to oxy hydrogen gas addition compared to the early injection strategy. HC emissions decreased for a lower oxy hydrogen gas flow rate of 200 ml/minutes However, smoke emissions were increased with oxy hydrogen gas induction due to an increase in BSFC. Oxides of Nitrogen reduced with oxy hydrogen gas addition by almost 44.13%
