“…Kapilan et al (2009) reported the same trend of increasing fuel injection pressure to improve engine performance. Other studies showed that a good diesel motor performance can be obtained by optimizing the flow pattern through valve opening, coolant pump speed regulation, engine rotation, and combustion; all of which can be achieved by changing the design of an engine component, namely, the piston (Aiyoshizawa 1999;Wahono et al 2019;Li et al 2020;Erdiwansyah et al 2019;Kumar et al 2018). The optimization of diesel engine should also consider fuel properties.…”

Diesel engines have been utilized for various purposes in Indonesia. Diesel engine manufacturers have developed designs and competed with each other to win the market in Indonesia. Nationally and internationally recognized standards are required to ensure the quality of products for Indonesia and the international market. The Indonesian National Standard (SNI) 119 is one of the recognized standards for single-cylinder diesel engine in Indonesia. Compared with the previous SNI 0119:2012, SNI 119:2020 has revised the limits of some parameters. This study evaluated the passing data of SNI test results from 2015 to 2020 and then analyzed the distribution of engines in each class for the comparison of limits between SNI 0119:2012 and SNI 119:2020 using normal distribution. Results showed that class D engines have the highest probability of passing the new limit of SNI 119:2020 at 98.59% to 100%. Meanwhile, class B has the lowest probability of acceptance at 38.68%. Power is the test parameter with the highest level of suitability, and specific fuel consumption is the parameter with the highest level of discrepancy for changes in SNI 119:2020.

“…The HC emission with the use of swirl piston, there has been a considerable decrement was noticed compared to normal piston even at 80% load with advanced injection timing. The NOx emissions are 275 ppm for swirl piston and 358 ppm for normal piston with 300 bar pressure and standard injection timing at 80 % load [8] On evaluating the effect of piston shape on in-cylinder flows in a direct injection engine using CFD, two pistonshapes namely flat and bowl types at wide-open-throttle under non-firing conditions are considered. From the analysis of results, it is found that bowl shaped piston generates higher TR and TKE than those of flat piston by about 15% and 12% respectively [9].…”

In the current development of automotive engines, the major target is to design a combustion chamber in such a way that the combustion process must provide very less concentrations of emissions. To satisfy current worldwide emission norms, petrol engines also equipped with direct fuel in-jection (gasoline/petrol directly injected into engine cylinder) same as like diesel engines. The main drawback of GDI engine is NOx and PM emissions due to lean burn combustion and rich mixture formation over the combustion chamber surface because of wall wetting. In GDI engines, the gasoline fuel injector is placed at various positions with different angles over an engine cylinder head as per the mode of combustion strategy. Based on the mode of combustion with fuel injection angle, the piston crown shape design in much important that the crown surface must not involved in wall wetting during injection. The piston crown shapes were modified for Spray guided combustion mode, Wall guided combustion mode and Air guided combustion mode by keeping in mind that the position of injector with fuel spray angle and the position of spark plug tip on the cylinder head. The main aim of modifying the crown surface profiles of piston is to impart swirl and squish effects for better mixing of air and injected fuel, maintain combustion chamber surface temperature range within the limits and also to avoid wall wetting results in chances of reducing soot particle/PM emission and NOx emission from combustion process.
