“…However, diesel engines can come to the fore in this transformation due to the fact that they generally have turbochargers, produced at high compression ratios and special combustion chamber geometries. Alternative cycles and fuels have emerged, especially with the conversion to diesel engines and alternative fuel studies (Asadollahzadeh et al 2021;Lalwani et al 2019;Dinler et al 2018). At the beginning of the alternative cycles are combustion techniques such as Premixed-Charge Compression Ignition (PCCI), Homogeneous Charge Compression Ignition (HCCI), and Reactivity Controlled Compression Ignition (RCCI).…”

In this study, the performance, combustion characteristics, and emission behavior of a diesel engine converted to a spark ignition engine running on natural gas were investigated. The initial diesel injection time of 719.5 CAD (Crank Angle Degree) was recognized as the spark ignition time, and no optimization work was done. RANS (Reynolds Averaged Navier-Stokes) k-e turbulence model, reduced methane chemical kinetic mechanism, and G-equation combustion model were all used in the numerical analysis. The studies were performed at full load, 2300 rpm, 17.5:1 compression ratio, constant spark ignition time, and 7 different swirl ratios. As a result, the homogeneous-air fuel mixture formed in the cylinder due to the the swirl ratio rising, and the increased combustion performance dominated the heat loss due to the rise in the swirl number, thereby improving the performance. However, with the increase of in-cylinder temperatures, NOX emissions increased. Following conversion, soot, carbon monoxide (CO), and unburned hydrocarbon (UHC) emissions levels remained practically extremely low. As the swirl ratio increased from 1.2 to 2.4, the GIP (Gross Indicated Power), IMEP (Indicated Mean Effective Pressure), ITE (Indicated Thermal Efficiency), and MPRR (Maximum Pressure Rise Rate) values increased by 4.1, 4.13, 3.98, 102.2%, while the GISFC (Gross Indicated Specific Fuel Consumption) value improved by 3.97%.

“…On the other hand, HCCI engine has certain drawbacks such as limited operating range, uncontrolled combustion, huge rise in heat release rate (HRR) and pressure rise rate (PRR) at higher engine load conditions (Agarwal et al , 2017; Pandey et al , 2018). These challenges can be overcome by several techniques such as variable compression ratio engine, exhaust gas recirculation (EGR) with swirl ratio (Sharma et al , 2015; Gowthaman and Sathiyagnanam, 2017), alcohol-based fuel additions (Polat, 2016), dual fuel injection (Park and Yoon, 2016; Lalwani et al , 2019) and variable valve train (Shaver et al , 2005). Similarly, premixed charge compression ignition (PCCI) and reactivity-controlled compression ignition (RCCI) are also used to overcome the main drawbacks of HCCI engine (Rahul Chowta et al , 2019).…”

Purpose Homogeneous charge compression ignition (HCCI) engine is an advanced combustion method to use alternate fuel with higher fuel economy and, reduce NOX and soot emissions. This paper aims to investigate the influence of ethanol fraction (ethanol plus gasoline) on dual fuel HCCI engine performance. Design/methodology/approach In this study, the existing CI engine is modified into dual fuel HCCI engine by attaching the carburetor to the inlet manifold for the supply of ethanol blend (E40/E60/E80/E100). The mixture of ethanol blend and the air is ignited by diesel through a fuel injector into the combustion chamber at the end of the compression stroke. The experiments are conducted for high load conditions on the engine i.e. 2.8 kW and 3.5 kW maximum output power for 1,500 constant rpm. Findings It is noticed from the experimental results that, with an increase of ethanol in the blends, ignition delay (ID) increases and the start of combustion is retarded. It is noticed that E100 shows the highest ID and low in-cylinder pressure; however, E40 shows the lowest ID compared to higher fractions of ethanol blends. An increase in ethanol proportion reduces NOX and smoke opacity but, HC and CO emissions increase compared to pure diesel mode engine. E100 plus diesel dual-fuel HCCI engine shows the highest brake thermal efficiency compared to remaining ethanol blends and baseline diesel engine. Originality/value This experimental study concluded that E100 plus diesel and E80 plus diesel gave optimum dual fuel HCCI engine performance for 2.8 kW and 3.5 kW rated power, respectively.
