Introduction

Hi my name is Radyan Jatya Gamana and this page is about my journey as a mechanical engineering student attending the ecs 2 class. Please let me know if there is any comment for my page.

Week 1 Discussion

The first week discussion is about "fuel" and I asked a question about it on the discussion.

There is already a massive conversation about the thinning of the fossil, coal, natural gas, etc as the main source of our energy or as we called "fuel". One of the negative effect of using these kind of energy source is the carbon emission.

The problem that we are facing now is to decrease the carbon emission to zero emission. If we are not to use carbon anymore is there some other energy vector besides carbon or fuel that can be used? Is it more environment friendly than carbon? And can it be more efficient than the usage of fuel?

28/02/2023 Class ICE, Pyrolisis, and EV

A discussion with Prof. Adhi about these three topics, first there were a demonstration using a piece of paper that is folded and it was lit on fire. How does the paper respon? The paper was on fire and it was one of the example of pyrolisis, when the fire was blown away there were still smoke. Why? because there were still oxidation proses that made the smoke circulate.

One of the factor that changes energy is about vibration and heat transfer. Understand about energy, vibration, and frequency if you want to be a good mechanical engineer.

A question : Dimana perbedaan ketiga topik tersebut?

In terms of environmental impact, ICE engines are known to produce harmful emissions such as carbon dioxide, and particulate matter. On the other hand, pyrolysis can be a more environmentally friendly process, as it can convert waste materials into useful products and reduce the amount of waste that ends up in landfills.

ICE Project

My project about one of the three topics that Mr. DAI requested is about the Internal Combustion Engine that is imbued in my personal car which is the Wuling Almaz and I will analyze the fuel consumption of my car. It is used daily for my trips to class or my other personal uses.

1. Internal Combustion Engine Definition

An internal combustion engine, sometimes referred to as an ICE engine, is a type of heat engine that transforms the energy from fuel combustion into mechanical labor. This kind of engine is frequently found in automobiles, trucks, and motorbikes.

An ICE engine runs on a four-stroke cycle, which includes intake, compression, combustion, and exhaust. The engine draws a mixture of gasoline and air into the cylinder during the intake stroke. On the subsequent compression stroke, the piston compresses the mixture. A spark is then used to ignite the compressed mixture during the combustion stroke, which results in a controlled explosion that pushes the piston downward and generates mechanical work. The piston forces the exhaust gases out of the cylinder during the exhaust stroke. ICE engines can run on various types of fuels, including gasoline, diesel, and natural gas.
