“…It was observed that diesel homo- 40 geneous combustion showed a two phase heat release pattern at higher premixed ratios and all combus- 41 tion parameters advanced dramatically with increasing premixed ratio. The results showed that a 42 reduction of 76% in NO X and 40% in smoke opacity were achieved using 80% premixed ratio with 30% 43 EGR. As the premixed ratio was increased, there was an improvement in IMEP, ISFC and smoke opacity 44 with penalties in HC and CO emissions.…”

“…The mode for PCCI implementation is chosen based on the power produced and the BMEP data. According to the literature review [9,10], the fourth mode and fifth mode are used to implement the PCCI method, as shown in Table 1. Based on the existing literature, a BMEP range of 6.5 bar to 1 bar is chosen [9,10].…”

Improvements in engine combustion are required due to the stringent pollution norms. This can be achieved either by making improvements in the combustion or by equipping after-treatment devices to control engine emission levels. PCCI is one of the popular techniques used to enhance the combustion. In this work, Diesel-RK software is used for the simulation. The main and pre-injection timings are altered to give the benefits in power and emissions. Based on a literature survey, the fourth and fifth modes are finalized for PCCI combustion simulation. The amount of total fuel injected was kept the same to compare the performances in DI and PCCI modes. The simulation results show the reduction in soot (PM) and NOx simultaneously with the help of PCCI concept at lower BMEP levels. The results show a decrease in PM by up to 26%, a reduction in NOx by up to 30% and an increase in power by 2%.

“…The power produced in that mode, as well as the brake mean effective pressure (BMEP) readings, is used to choose the mode for PCCI deployment. According to the literature review available [16,17], mode 4 and mode 5 are used to execute the PCCI approach, as shown in Table 1. Hence, the range of 1 bar to 6.5 bar BMEP is chosen based on the literature available [16,17].…”

Homogenous charge compression ignition (HCCI) is a technology for concurrently reducing nitrogen oxides (NOx) and particulate matters (PM) emissions. Since, the pure HCCI lags in control over combustion phasing, Pre-mixed charge compression ignition (PCCI) method is proposed. To achieve partial homogeneity in PCCI combustion, the air is pre-injected with fuel. The main injection is required for the combination to take place. This paper investigates the impact of using the varying percentages and types of bio-diesels for the constant speed genset application engine. The paper first discus the effect of various ratios of diesel and biodiesel mixtures on the performance parameters like engine power, specific fuel consumption (sfc) and the break thermal efficiency. These effects are caused by the combustion happening inside the combustion chamber which can be seen in pressure, temperature and heat release curves. The result of the simulation finally discusses the formation of NOx and PM emissions during the combustion. These results also provide guidelines for actual testing of the engine with bio-diesel.
