“…This can mean two things: 1) that the engine operates with two different combustion processes over the entire range of operation of the engine, and 2) that the engine operates in HCCI with a pilot injection, as a dual fuel engine, with the injection occurring inside the intake air system just prior to entry into the cylinder or directly into the cylinder. Stanglmaier and coworkers at Southwest Research Institute developed a dual fuel natural gas engine to operate in HCCI mode at idle to mid range operation to improve fuel efficiency and reduce NOx emissions [149]. Although the goal of the experimentation was achieved, higher levels of HC and CO emissions were also observed [149].…”

“…The goal is that each fuel would burn in succession and thus spread out the combustion event duration, termed heat release elongation (HRE), which would help overcome the problem of too rapid rate of pressure rise. Examples of this fuel blending strategy include using dimethyl ether (easy to autoignite) mixed with methane (difficult to autoignite) [13], naptha with methane [14], and octane with n-heptane [15].…”

The influence of the small amounts (1-3%) of the additive di-tertiary butyl peroxide (DTBP) on the combustion event of Homogeneous Charge Compression Ignition (HCCI) engines was investigated using engine experiments, numerical modeling, and carbon-14 isotope tracing. DTBP was added to neat ethanol and diethyl ether (DEE) in ethanol fuel blends for a range of combustion timings and engine loads. The addition of DTBP to the fuel advanced combustion timing in each instance, with the DEE-in-ethanol mixture advancing more than the ethanol alone. A numerical model reproduced the experimental results. Carbon-14 isotope tracing showed that more ethanol burns to completion in DEE-in-ethanol blends with a DTBP additive when compared to results for DEE-in-ethanol without the additive. However, the addition of DTBP did not elongate the heat release in either case. The additive advances combustion timing for both pure ethanol and for DEE-in-ethanol mixtures, but the additive results in more of an advance in timing for the DEE-inethanol mixture. This suggests that although there are both thermal and kinetic influences from the addition of DTBP, the thermal effects are more important.
