Individual Project

Introduction

As what mr DAI already said, we need to made an Individual project and we need to choose a topic between 3 topics which are about Pyrolisis, Electric Vehicle, and Internal Combustion Engine

Chosen Topic :

I am choosing Internal Combustion Engine as a topic for my Individual Project with the title

Effect of Octane on Performance and Energy Consumption on BMW E36 330i

Abstract

The combustion performance of gasoline engines has traditionally been measured using Research Octane Number (RON) and Motor Octane Number (MON) which describe antiknock performance under different conditions. Recent literature suggests that MON is less important than RON in internal combustion engine cars and a relaxation in the MON specification could improve vehicle performance, while also helping refiners in the production of gasoline. At the same time, for the same octane number change, increasing RON appears to provide more benefit to engine power and acceleration than reducing MON. It has also been suggested that there could be fuel efficiency benefits (on a tank to wheels basis) for specially adapted engines, for example, operating at higher compression ratio, on very high RON (100+). Other workers have advocated the use of an octane index (OI) which incorporates both RON and MON to give an indication of octane quality. The aim of this work is to investigate the effect of RON and MON on the power output and acceleration performance of gasoline-powered vehicles under full-throttle acceleration. The test was carried out in the context of the BMW E36 330i. RON oil cover Ratings of 91-98 and sensitivity at 15 (RON - MON) were mixed. Pure hydrocarbons and mixtures containing ethanol or ETBE can be included to determine the specific effect of the oxidizing agent. The results confirm from other studies that MON is not a good predictor of vehicle performance and that, in fact, high levels of MON under all acceleration conditions increase acceleration time.

Introduction

Octane rating is a measure of a fuel's resistance to auto-ignition. Spark-ignition gasoline engines have pressure Relying on auto-ignition to lower octane (or high cetane number fuel). The octane rating of fuel is measured in special testing machines called CFR engines. This is a cylinder test engine with a different compression ratio. Even the test progresses Improvements have been made over the years, and the engine process and testing are 1928. Tests in the early 1930s showed that fuel behavior in cars of that era did not correlate with octane rating, so the new, stricter engine octane rating was created. Both methods are still used today.

The research octane number (RON) is measured at a speed of 600 rpm at a temperature of 52°C. Traditionally associated with small and medium sized vehicles. Introduction to Engine Octane Number (MON) It simulates more difficult high load conditions and uses a higher engine speed of 900 rpm and control compensation. Temperature of 149°C. The MON of a fuel is generally about 10 less than its RON. Fuel specifications usually establish minimum values ​​for RON and MON. car inspection is growing The data show that the traditional expectation that RON is associated with less work and MON with more serious driving does not hold (Huber et.al (2013), CRC (2011), CRC (2012), Foong (2013) , Kalghatgi (2001). Kalghatgi too. eggs. (2005), Kalghatgi (2005), Mittal and Heywood (2008), Bell (2010), Davies et. eggs. (2011), Amer et al. eggs. (2012), Lemmer et al. eggs. (2014). The Anti-Knock Index used in the United States and other countries is a special case. First, the relationship between the octane requirement of the car, RON and MON, which can be represented by:

Octane Index = (1-K).RON + K.MON = RON – K.S

where S is the sensitivity of the fuel, defined as (RON-MON). With K set to 0.5, the octane index becomes the same as the AKI, (RON+MON)/2.

Class of 28/02/2023

Hari ini, prof Adi menanyakan ke kita semua mengenai 3 topik yang telah diberikan oleh pak DAI pada pertemuan sebelumnya yakni ICE, Pyrolisis, dan Electric Vehicle. Sebenarnya, saya pribadi memilih untuk mendalami topik ICE dikarenakan saya sangat menyukai otomotif, namun dari sumber berita yang saya baca bahwa Indonesia akan melarang dan memblokir penggunaan mobil berbahan bakar bensin dan solar pada tahun 2050 dengan tujuan untuk mengurangi gas emisi pembuangan.

Topik yang menjadi fokusan utama pada kelas hari ini adalah Pyrolisis.Pyrolisis sendiri adalah proses dekomposisi suatu bahan pada suhu tinggi yang berlangsung tanpa adanya udara atau dengan udara terbatas.
