“…Although hydrogen energy is in many ways an ideal alternative for gasoline engines, it has critical problems including its low energy density, insufficient infrastructure, and high cost as a primary fuel. Ganesh et al [3] experimentally investigated the performance of a hydrogen-fueled spark ignition engine, and showed that the peak power output of a hydrogen engine was 20% lower than that of a gasoline engine. Also, the specific fuel consumption (SFC) and total fuel consumption (TFC) of the hydrogen engine were much lower than those of the gasoline engine.…”

“…The most serious problem with PI is the significant possibility of pre-ignition and backfire, especially with rich mixtures Ganesh, Subramanian, Balasubramanian, Mallikarjuna, Ramesh & Sharma, 2008). However, conditions with PI are much less severe and the probability for abnormal combustion is reduced because it imparts a better resistance to backfire (COD, 2001).…”

“…Then, injection of the hydrogen with a relatively low temperature of 0-10 °C, such that the combustion chamber is cooled by the hydrogen and finally, lowering of the compression ratio to 8:1. One of the main conclusions drawn from the experimental study of Ganesh et al (2008) was the possibility of overcoming the problem of backfire by reducing the injection duration. Sierens and Verhelst (2003) examined four different junctions of the port injection position (fuel line) against the air flow.…”

Hydrogen induction strategy in an internal combustion engine plays a vital role in increasing the power density and prohibiting combustion anomalies. This paper inspects the performance characteristics of cylinder hydrogen-fueled engine with port injection feeding strategy. To that end, a one-dimensional gas dynamic model has been built to represent the flow and heat transfer in the components of the engine. The governing equations are introduced followed by the performance parameters and model description. Air-fuel ratio was varied from a stoichiometric limit to a lean limit. The rotational speed of the engine was also changed from 1000 to 4500 RPM. The injector location was fixed in the mid-point of the intake port. The general behavior of the hydrogen engine was similar to that of a gasoline engine, apart from a reduction in the power density, which was due to a decrease in the volumetric efficiency. This emphasizes the ability of retrofitting traditional engines for hydrogen fuel with minor modifications. The decrease in the volumetric efficiency needs to be rectified.

“…Furthermore, external mixture formation provides a greater degree of freedom concerning storage methods. The most serious problem with PFI is the high possibility of pre-ignition and backfire, especially with rich mixtures [10][11] . However, conditions with PFI are much less severe and the probability for abnormal combustion is reduced because it imparts a better resistance to backfire.…”

This study was focused on the engine performance of single cylinder hydrogen fueled port injection internal combustion engine. GT-Power was utilized to develop the model for port injection engine. One dimensional gas dynamics was represented the flow and heat transfer in the components of the engine model. The governing equations were introduced first, followed by the performance parameters and model description. Air-fuel ratio was varied from stoichiometric limit to a lean limit and the rotational speed varied from 2500 to 4500 rpm while the injector location was considered fixed in the midway of the intake port. The effects of air fuel ratio, crank angle and engine speed are presented in this study. From the acquired results show that the air-fuel ratio and engine speed were greatly influence on the performance of hydrogen fueled engine. It was shown that decreases the Brake Mean Effective Pressure (BMEP) and brake thermal efficiency with increases of the engine speed and air-fuel ratio however the increase the Brake Specific Fuel Consumption (BSFC) with increases the speed and air-fuel ratio. The cylinder temperature increases with increases of engine speed however temperature decreases with increases of air-fuel ratio. The pressure fluctuations increased substantially with increases of speed at intake port however rise of pressure at the end of the exhaust stroke lead to reverse flow into the cylinder past exhaust valve. The fluctuation amplitude responded to the engine speed in case of exhaust pressure were given less than the intake pressure. The volumetric efficiency increased with increases of engine speed and equivalent ratio. The volumetric efficiency of the hydrogen engines with port injection is a serious problem and reduces the overall performance of the engine. This emphasized the ability of retrofitting the traditional engines with hydrogen fuel with minor modifications.
