“…Under the clearly high combustion temperatures, supported further by the combustion of the Hydrogen in the overall fuel supplied to the engine, the nitrogen present in the air reacts with oxygen to form NO x . A recent study [3] showed that hydrogen fuel supplement can be used in diesel engine with hydrogen to diesel ratio of 34% calculated based on amount of energy in the fuel (which represent 19% as mass ratio between hydrogen to diesel).…”

“…The recent price climbs of crude oil products has led scientists and engineers to explore the use of alternative possible fuels to run compression ignition engines such as LGP [1] and hydrogen [2,3], in order to replace diesel or at least reduce its use as a fuel for engines. The use of hydrogen in diesel engines is driven by multiple reasons [2] which are (1) increases the hydrogen to carbon ratio of the entire fuel supplied to the engine, (2) injecting small amounts of hydrogen into a diesel engine can decrease the heterogeneity of diesel fuel spray, and (3) reduces the combustion duration.…”

Particulate matter and gaseous emissions a b s t r a c tThe present work investigates experimentally the behavior of compression ignition engine while boosting the combustion by enriching air-intake manifold with hydrogen supplement at the atmospheric condition. The study reports the engine thermal efficiency, NO x emissions and engine exhaust temperature while varying hydrogen content, engine speed and ignition timing. The results show that thermal efficiency of the compression ignition engine increases as hydrogen content increases in the air-intake manifold for the same diesel mass flow rate. The effect of hydrogen supplement on engine efficiency is more pronounced at low engine speed and part-load. The hydrogen supplement causes an increase in NO x emissions which is attributed to the increase in the combustion temperature and as a result, lower smoke opacity numbers are attained.

“…The use of hydrogen in compression ignition (CI) engines shows brighter prospect when compared to spark ignition (SI) engines since the use of hydrogen as a fuel in spark ignition engine has showed a significant reduction in power output [6]. In addition, at high load multiple problems have been reported in spark ignition such pre ignition, backfire and knocking [6]. These problems have limited the use of hydrogen in SI engine [7,8].…”

“…Das et al reported that the maximum brake thermal efficiency of 31.3% is obtained at 2200 rpm with 13 N-m torque. Recently, Hamdan et al [8] showed that the use hydrogen could boost compression engine efficiency by more than 10% and reduce specific fuel consumption by more than 35% at the same load. Hamdan et al [9] has reported an increase in thermal efficiency of more than 35% for dual injection at low speed (1080 rpm) and more than 8% at high speed (1800 rpm), where diesel is injected at 35 degree from btdc.…”

Abstract.This experimental study evaluates the feasibility of supporting compression ignition engine that primary run on diesel fuel with hydrogen gas that is produced by solar-hydrogen cycle. A photovoltaic panel is used to produce hydrogen through electrolysis from solar energy. Different mass ratio of hydrogen enrichment to liquid diesel fuel are tested on an engine operating under fixed torque of 14.7 N-m and engine rotational speed of 1100 rpm. Under same loading condition, the study shows that hydrogen can be used to reduce diesel fuel consumption and CO2 emission however this comes on the cost of increasing of NOx emission. The results show that beyond a maximum mass ratio of hydrogen-to-diesel of 9.7%, the engine starts knocking. The experiment shows that adding hydrogen to the air intake of a diesel requires a simple pluming operation in which hydrogen is allowed to enter the engine from the air intake manifold and hence the cost of retrofitting of current diesel engine is considered marginal.
