The research of normal combustion, knock and super-knock in highly boosted gasoline engine could be conducted on a RCM platform associated with optical methods to obtain the pressure traces and …
Many researchers have investigated the cause of cyclic variation with a focus on the ignition and combustion process in SI engine. In both experimental and simulation studies, the early phase …
A single-cylinder high-compression-ratio engine with the specifications was shown in Table 1. The tested engine was designed so as to enhance thermal efficiency under lean conditions around an excess air …
To estimate the actual electric energy consumed of spark plug in the cylinder, the resistance of the ignition system was considered. The equivalent circuit of spark plug used in the …
To discuss the combustion speed, heat release was estimated from the in-cylinder pressure waveform. First, the heat-release rate was calculated by Eq. using combustion analysis software (Ono Sokki, DS0328). And …
The lean combustion concept has several advantages for the thermal efficiency enhancement of internal combustion (IC) engines: (1) the reduction of pumping loss resulting from throttle opening, (2) the reduction …
