“…In an external mixture preparation strategy, A‐F mixture will be formed in the intake manifold with a partial or complete injection of low‐pressure fuel through port fuel injection, fumigation, 14‐16 or various induction techniques. Low volatile fuel like diesel can also be used through a fuel vaporization technique 17 . The complete induction or injection of fuel through external mixture formation technique has shown a huge decrement in NO x and smoke emissions in conventional CI engines.…”

The present experimental study was aimed to investigate the combined effect of external mixture formation and cooled exhaust gas recirculation (EGR) on performance and emissions characteristics of partially homogeneous charge compression ignition (PCCI) engine. A conventional single‐cylinder four‐stroke compression ignition engine was modified to operate on PCCI mode with the supply of diesel fuel vapor via intake manifold during suction stroke. A Homogenous air‐fuel charge was produced by using a retrofit system to provide fuel vapor. The engine was operated in two modes, direct injection (DI)‐EGR and PCCI (DI‐fuel vapor‐EGR) mode, and then results were compared with DI (conventional) mode. Constant 10% EGR was maintained during DI‐EGR and PCCI modes. Compared to conventional mode, in PCCI mode at full engine load, NOx and smoke opacity were decreased by 2.39 g kW−1 hr−1 and 27% respectively, and the marginal penalty in HC and CO emissions by 0.4 and 0.1 g kW−1 hr−1 was observed. Brake thermal efficiency was slightly reduced by 2.5% compared to DI mode.

Combustion of fossil fuels provides around 88% of total energy supply for modern society, and meanwhile causes many environ mental problems and social problems such as air pollution and energy crisis. Therefore， both at home and abroad are focusing on the research and development of natural gas engine recently.However, the mass production and application of this kind of engine are restricted by some unsolved technical difficulties. This paper explored the injection, combustion and emission processes of diesel/ natural gas and dual fuel engine based on Chemkin II, Fire software and Schlieren method. The experimental study on the mixing process of dual fuel jet was carried out by using high-speed Schlieren method in a constant volume bomb. Based on the Fire software, and then applied to Chemkin II software to analyze the effect of the initial temperature and pressure on the net heat production and combustion emissions. The results show that Dual fuel mechanism is capable of producing different heat production behaviors when varying the initial pressure and temperature CO2 emissions are minimized by changing the initial pressure above or below the atmospheric value. However, CO emissions are peaked when diesel fuel is used. The dual fuel engine minimizes the CO emissions amount caused by diesel fuel. Increasing the initial pressure eliminates dual fuel CO2 combustion emissions. The research of this paper is important to optimize the in cylinder combustion processes of natural gas engine, and have a certain important meaning to guide the development of diesel ignition dual fuel engine.
