Performance and emission characteristics of hydrogen fueled spark ignition engine

Sustainable development of road transportation sector using hydrogen energy system

“…Humankind needs a basic energy source and hydrogen is the most sensible choice [12]. Mathur and Khajuria [13] reported that the hydrogen engine can operate at wide air-fuel ratio. The hydrogen as fuel for SI engines have many attractive features, but it tend to suffer from frequent pre-ignition combustion events, especially under high load conditions.…”

“…The use of hydrogen as fuel for SI engines is advantageous due to high thermal efficiency and low exhaust pollutant levels [91,98]. But there is a setback of pre-ignition in the hydrogen engine operation using premixed intake charge formation, resulting in an intake manifold 'backfire or flashback', reduced volumetric efficiency and output power drop due to low fuel energy density on volume basis, and high NO x formation [9,13,20,90]. MacCarley and Vorst [99] introduced the timed fuel injection technique at the intake port or directly into the cylinder.…”

Series Hybrid Vehicles and Optimized Hydrogen Engine Design

“…6, where the difference between the ideal thermal efficiency calculated from Eq. (1) and the measured indicated thermal efficiency of King et al ., Oehmichen (Oehmichen 1942), and Mathur (Mathur and Khajuria 1984) are plotted against the surface-to-volume ratio which has been estimated from the engine schematic and dimensions provided in their papers. (Figures 5 and 6 also include preliminary data from the Onan experiment and are discussed later.…”
