“…Conditions (LTC), such as Homogeneous Charge Compression Ignition (HCCI), Partially Premixed Compression Ignition (PPCI) and others, have shown to be a good solution to reduce pollutant emissions while keeping, or even improving, the engine efficiency [1]. However, new combustion strategies have shown different challenges to overcome before implementing these technologies in commercial engines.…”

A phenomenological explanation about the autoignition propagation under HCCI conditions is developed in this paper. To do so, diffusive effects from the burned zones to the fresh mixture, pressure waves based effects and expansion effects caused by combustion are taken into account. Additionally, different Damköhler numbers have been defined and evaluated in order to characterize the phenomenon and quantify the relevance of each effect.

“…Because of these advantages, HCCI combustion mode take attention over last few decades and researchers have performed a lot of studies about HCCI combustion. In most of these experimental researches reference fuels are tested in HCCI engines as well as the using alternative fuels such as natural gas, liquid petroleum gas, biodiesel and alcohol [34][35][36][37][38].…”

The depletion of fossil fuels as a result of excessive use and increased environmental pollution brought up the research of environmentally conscious and renewable alternative fuels. The alternative fuel to be considered for internal combustion engines should not decrease the performance of the engine too much and positively affect the exhaust emissions. It is also important that this fuel should provide some specifications such as easy producibility, low cost, availability and usability in internal combustion engine without modification. Low temperature combustion modes are promising technologies providing nearly zero NOx and soot emissions and currently a lot of researcher has focused on this technology. In this experimental study naphtha was tested in an HCCI engine. In order to examine and understand the effects of the naphtha on HCCI mode a comparison study was also conducted by using RON68. Maximum imep was computed as 3.23 and 3.32 bar with RON68 and naphtha respectively at λ=1.7. SOC was determined 5.4 °CA and 5.76 °CA ATDC with naphtha and RON68 at λ=2. CA50 is far away from TDC fact that net work decreases. Maximum ITE was calculated as 45.42% and 46.07% at λ=2 with RON68 and naphtha respectively.
