This paper studied the engine test cycles including world harmonized steady cycle (WHSC), world harmonized transient cycle (WHTC) , china heavy-duty steady cycle (CHSC) and china heavy-duty transient cycle (CHTC) based on a diesel engine which meet the China VI heavy duty vehicle emission standard. The results show that regression analysis of speed, torque and power all meet the requirements of the China VI heavy duty vehicle standard. For this engine, NOx, PM and THC pollutants under CHSC are 134.5%, 29.6% and 94.4% higher than those under WHSC, respectively. PN emissions of CHSC is 65.6% lower than that of WHSC. NOx, PM and PN pollutants under CHTC are 62.9%, 96.4% and 64.3% higher than those under WHTC, respectively. The exhaust temperature of the first 350 seconds at CHTC is lower, which poses a greater challenge to the conversion efficiency of the after-treatment system at low speed and low load.

Using Data

In Indonesia, transportation sector, specifically road transport consumed most energy compared to other sectors. Eventually, the energy consumption will increase due to the growth of vehicle number that also escalate emission. Vehicle emissions had been recognized as a significant contributor to atmospheric greenhouse gas (GHG) pollution. Heavy-duty vehicles are considered as main sources of vehicular emissions in most cities. Therefore, it is crucial to take into account heavy-duty vehicle emission projections in order to support policymakers to identify vehicle emissions and develop pollution control strategies. The aim of this study is to forecast heavy-duty vehicle population, vehicle kilometers travelled (VKT), fuel consumption, and heavy-duty vehicle emissions using data of Semarang City to illustrate greenhouse gas emission of big cities in Indonesia. Business as Usual (BAU) and The Intergovernmental Panel on Climate Change (IPCC) method were incorporated to determine vehicle emission projection. Heavy-duty vehicle emissions increase from 2021 to 2030 by 12.317 to 22.865 Gg CO2/year with amount trucks and buses emissions of 21.981,5 Gg CO2/year and 884,2 Gg CO2/year, respectively.

In this study, the emissions of Kirloskar Direct Injection 4-stroke Diesel engine, single cylinder air cooled, 4.4 kW, constant speed at 1500 rpm, compression ratio 17.5:1 with different blends of diesel refined sunflower oil is analysed. Methyl Esters of refined sunflower was trans-esterified before blending with diesel. The main objective of this experiment is to study the NOx, CO, HC and smoke emissions by varying the injection timing and load. The experiments were conducted with various blends - BRSF10, BRSF30, BRSF40, at different pressures (180 bar, 210 bar, and 240 bar) and different level of loads (0%, 25%, 50%, 75%, 100%). A 3-hole nozzle was used to inject the fuel. The combustion results were studied using AVL gas analyser. The results show that engine temperature decreases at higher loads by 2°, NOx and CO decreases and there was a marginal increase in HC and the exhaust temperature.
