“…The deviation in indicated power is mainly due to the loss in mean effective pressure as described earlier. Considering 13.5 kg load condition for HMMC piston engine operated at 200 bar pressure of fuel injection, a reduction of indicated power of 14% was attained against 9.9% reduction with 220 bar pressure of fuel injection when compared with standard piston operation [24].…”

The increase in demand and introduction of stringent emission regulations resulted in the need to develop and implement innovative technologies towards improving the emission and performance characteristics of compression ignition engines. A hybrid metal matrix composite piston (HMMC) of Al7075 reinforced with 6% of 100 ?m Silicon Carbide (SiC) and 4% of 100 ?m Aluminium oxide (Al2O3) was fabricated. The HMMC piston was mounted on a compression ignition (CI) four stroke single-cylinder constant speed engine and the test was carried out with eddy current dynamometer attached with computerized data acquisition system. This paper is focused on the study of performance of Al7075-SiC-Alumina composite piston for compression ignition engine application. Experimental investigations were performed at injection pressure of 200 and 220 bar on both standard piston and HMMC piston and analysed the performance, combustion and emission behaviour of CI engine. From the results it was found that the HMMC piston exhibits an improved efficiency and thereby improving the lifetime of the engine. Though a little compromise in performance and emissions has been accepted, the implementation of HMMC pistons will reduce the carbon foot print of running an internal combustion engine.

“…In a single-cylinder compression ignition engine, Naseeb Kahn et al [52] utilized B20 as the pilot fuel and supplied hydrogen at a rate of 15 liters per minute. They then compared brake-specific fuel consumption, the brake thermal efficiency, and Nox emission different injection opening pressure.…”

One of the major issues, the energy crisis, makes the globe dangerous and violent [1]. Every day, there is an increase in energy demand. Resources of energy are running out swiftly, and all indicators point to their impending demise. In such cases, renewable energy sources must be given more consideration. The widespread use of fossil fuels renders them unsustainable because they increase CO2 levels and emit greenhouse gases that harm the environment [2]. With several trials of usage of HHO gas or compressed natural gas as a fuel performance improver on both internal combustion engines powered by gasoline or diesel up until this point, many advancements have been made in this field[3]. This paper comprises a survey of the numerous advancements that have occurred in this area. There was a net lead to an amplified in brake power from 2.1% to 5.8% and an increase in brake thermal efficiency from 10.27% to 35% with the addition of HHO gas. The usage of traditional fuels decreased by 20% to 30%, and HC and CO exhaust emissions decreased by an average of 14% and 18%, respectively.

“…However, 30% of water injection resulted in 37% efficiency and lowered NOx emissions. Khan et al [41] scrutinized the performance and emission qualities of a CI engine functioned on a dual fuel mode employing a B20 combination and analyzed the influence of injection pressure and hydrogen injection (15 lpm). They have operated the engine on dual fuel mode.…”

The present work is mapped to scrutinize the consequence of biodiesel and gaseous fuel properties, and their impact on compression-ignition (CI) engine combustion and emission characteristics in single and dual fuel operation. Biodiesel prepared from non-edible oil source derived from Thevetia peruviana belonging to the plant family of Apocynaceaeis. The fuel has been referred as methyl ester of Thevetia peruviana (METP) and adopted as pilot fuel for the effective combustion of compressed gaseous fuel of hydrogen. This investigation is an effort to augment the engine performance of a biodiesel-gaseous fueled diesel engine operated under varied engine parameters. Subsequently, consequences of gas flow rate, injection timing, gas entry type, and manifold gas injection on the modified dual-fuel engine using conventional mechanical fuel injections (CMFIS) for optimum engine performance were investigated. Fuel consumption, CO, UHC, and smoke formations are spotted to be less besides higher NOx emissions compared to CMFIS operation. The fuel burning features such as ignition delay, burning interval, and variation of pressure and heat release rates with crank angle are scrutinized and compared with base fuel. Sustained research in this direction can convey practical engine technology, concerning fuel combinations in the dual fuel mode, paving the way to alternatives which counter the continued fossil fuel utilization that has detrimental impacts on the climate.
