“…The introduction of HHO gas in the combustion chamber increases the overall octane number of the fuel mixture 25 . The high flame speed of hydrogen creates instant combustion reducing the heat losses 26 . The reduction in ignition delay and shorter combustion period due to the high‐octane number of hydrogen gas also contributes to lower heat losses, creating combustion close to the ideal constant resulting in high‐thermal efficiency 27 .…”

Carbon emission and problems associated with the world have been the major concerns for the past few decades. The world governments have implemented stringent emission norms to reduce the pollution created by hydrocarbon combustion in automobiles. The use of gaseous fuels in IC engines has gained interest among the research community. In the present research work, hydrogen, and oxygen (HHO gas) are produced together in an electrolyzer unit and is fed into the engine intake manifold before the carburetor. The electrolyzer consists of an anode, cathode and five neutral plates made of 316 L SS. Electrolyser production rate was tested with four different molarity conditions of NaOH electrolyte solution ranging from 0.24 to 1 N. It was noted that a maximum of 2 LPM of HHO gas was produced with the supply of 90 A‐h current at 1 N solution concentration. The performance and emission characters of the SI engine were conducted at six different load conditions and four flow rates of HHO gas. HHO gas induction has significantly increased the thermal brake efficiency by 8% and decreased the specific fuel consumption by 20%. With the supply of 2 LPM of HHO gas, CO2, HC, and NOx emissions were reduced by 67%, 59%, and 34%, respectively.

“…As for SI [10,12] or reactivity controlled compression ignition (RCCI) engines [8,13], dualfuel technology can be used in HCCI engine. Recently, Mahmoodi et al [6] investigated dual fuel (reformed biogas/ diesel fuel), numerically on the combustion behavior, performance and emission characteristics of a reactivity controlled compression ignition (RCCI) engine.…”

“…However, some high-octane fuel does not participate in oxidation reactions due to its low self-ignition tendency, increasing the hydrocarbon emissions. Very recently, Feroskhan et al [13], studied the operation of a Homogeneous Charge Compression Ignition (HCCI) engine using simulated biogas and diethyl ether (DEE) as the primary and secondary fuels respectively. Performance, emission and combustion parameters are measured for various biogas flow rates, composition (50 to 100% methane), intake temperatures and loads, and they investigated two ways to injecte DEE at the intake port and by manifold injection.…”

“…Multi-criteria evaluation models can also be used as a tool for predicting biogas performance in IC engines, such as prognostic statistical models for estimating the impact of biogas flow on engine performance [27], or the selection of the optimal proportions of diesel/n-butanol/biogas in the fuel mixture [28]. The 0-D model was used to predict IC engine performance [29].…”

Biogas has increasingly been used as an alternative to fossil fuels in the world due to a number of factors, including the availability of raw materials, extensive resources, relatively cheap production and sufficient energy efficiency in internal combustion engines. Tightening environmental and renewable energy requirements create excellent prospects for biogas (BG) as a fuel. A study was conducted on a 1.6-L spark ignition (SI) engine (HR16DE), testing simulated biogas with different methane and carbon dioxide contents (100CH4, 80CH4_20CO2, 60CH4_40CO2, and 50CH4_50CO2) as fuel. The rate of heat release (ROHR) was calculated for each fuel. Vibration acceleration time, sound pressure and spectrum characteristics were also analyzed. The results of the study revealed which vibration of the engine correlates with combustion intensity, which is directly related to the main measure of engine energy efficiency—break thermal efficiency (BTE). Increasing vibrations have a negative correlation with carbon monoxide (CO) and hydrocarbon (HC) emissions, but a positive correlation with nitrogen oxide (NOx) emissions. Sound pressure also relates to the combustion process, but, in contrast to vibration, had a negative correlation with BTE and NOx, and a positive correlation with emissions of incomplete combustion products (CO, HC).
