Simulasi Cara Kerja Mesin 4 Tak (Video Animasi)

Pada mesin 4 tak, pembakaran terjadi setiap dua kali putaran engkol. Pertanyaannya, bagaimana caranya ? bagaimana bisa pembakaran itu memutar poros engkol sampai dua kali putaran ?   Video ini akan menjadi jawaban tentang semua mesin 4 tak.   Tak usah banyak basa-basi, langsung saja kita bongkar mesin 4 tak. Seperti yang anda lihat, ini adalah komponen-komponen utama yang terdapat pada sebuah mesin 4 tak. Ada piston, ada silinder, ada kepala silinder, ada mekanisme engkol, dan ada mekanisme katup.   Pergerakan semua komponen ini, saling terhubung secara mekanikal untuk menghasilkan sebuah siklus pembakaran.   Biar lebih jelas, saya akan jelaskan konsep pembakaran pada internal combustion engine. Jadi, dalam mesin ini, sumber tenaganya berasal dari pembakaran. Apa yang dibakar ? tentu saja bensin.   Tapi, bensin ini tidak bisa dibakar begitu saja. Apalagi alat untuk membakar bensin ini bukan bara api seperti korek, melainkan Cuma busi yang percikannya sangat kecil.

How Hydraulic Jack Lift Heavy Weight With Small Input Force ?

Image
Hydraulic jack always be an option if we work with heavy equipment. For example when we want to change car’s wheel. To do that, we need to lift the vehicle. And hydraulic jack is a good choice to do that job. But how the hydraulic jack can lift the heavy weight with small input force ? in this article, I will show you inside the hydraulic jack when it works. hydraulic jack animation Hydraulic jack work using pascal’s law. With this principle, the hydraulic jack has an ability to lift a weight that has two or three time heavier than the input weight. But here, I want to talk a lot about physics. I just want to show you how powerful this pascal principle, of course in simple explanation. So, it can be said that the area very influence the weight can be hold. If you ever see a raft. When you stand in the raft with small area, you can sink. But if we make the raft larger, it can accommodate two or three people without sink. It is a proof that the area very affected with the weight can be a

Continuous Variable Transmission (CVT) Working Principle

  We already know that the job of the transmission is to change the speed ratio between the engine and the wheels of an automobile. The transmission use two gears with different diameters. So that the rotation from the crankshaft, can be change to make it has more torque with lower speed. But how about automatic transmission ? did this thing using several gears or not ? In this article, we will learn about CVT transmission. Which is this transmission, widely use in automatic motorcycles. Basic of Automatic Transmission Unlike traditional automatic transmissions, continuously variable transmissions don't have a gearbox with a set number of gears, which means they don't have interlocking toothed wheels. The most common type of CVT operates on an ingenious pulley system that allows an infinite variability between highest and lowest gears with no discrete steps or shifts. To change the speed ratio, CVT use variable diameter pulley. This pulley has ability to change the diameter, ac

Can a Car Battery Charge Itself ?

Image
Vehicle battery is a component that store electrical energy for the vehicle use. Note that the battery is only a stored component. It mean the battery only use to save the electricity. So, the battery (in general ) has 12 Volt voltage at full charge. When we use the battery, there is discharge voltage that makes the battery voltage drop in slowly. But because the battery has no ability to recharge, it make the battery going to empty if it use for long time. But, we never change the battery daily right ? it mean the batteries voltage always stable in 12 Volt. What makes the battery stable even it always use ? The answer is simple, the vehicle has charging system. The battery has no ability to recharge so that we need another system to recharge the battery. Battery Function in Vehicle the main responsibility of a vehicle battery is to provide the starting current needed to start the car, it is also responsible for powering all the other electrical components of the car, such as the headl

What is Material Use in Electric Car Batteries ?

  The battery use in electric vehicle is different from battery use in engine powered vehicle. Electric vehicle totally use electricity as source of energy to drive the electric motor. So, rotation from the motor will rotate the wheel and it move the vehicle. But what makes it different ? what is the material use to make electric car batteries ? Electric vehicle use a battery know as li-ion battery. This batteries had been widely use in electronic devices such as gadget, and laptop. So what is the different between li-ion and lead acid battery on vehicle ? Lithium, Nickel, and cobalt are the main container of electric vehicle battery. 1.  What is Lithium ? Lithium is a silvery-white alkali metal that is light and malleable. It is the lightest metal available. The Earth's crust has about 20 parts per million of lithium, and the oceans have 0.17 parts per million; the atmosphere has only trace quantities. With some very basic chemistry, the amount of lithium that a battery must produ

What Type of Battery Is In an Electric Car ?

Electric vehicle become the new interest for several people. The main reason, electric vehicles do not cause carbon residue. As the name implies, the electric vehicle uses an electric power source as a substitute for fuel oil. So that in an electric car there is no combustion engine, that is what makes the electric vehicle not cause bad emissions. just like other electronic equipment, the source of electricity in the electric vehicle is stored in the battery. Then we have a question, what type of batteries use in electric vehicle ? It is impossible to use lead acid battery because it has low capacity if it use to drive the car. So what kind of battery ? Lithium Ion Battery The lithium-ion battery is the most common type of battery used in electric vehicles. This type of battery is used in most portable devices, including mobile phones and computers, so it may sound familiar. Lithium-ion batteries have a good high-temperature output, a high power-to-weight ratio, and a high energy effic

How to Read and Choose Correct Battery Size For Your Vehicle

  The size of your car battery and selecting the correct battery for your vehicle's make and model are critical. If you choose the wrong one, your car will not work as it should or may, regardless of its specifications or how well it is maintained. The spark that ignites the fuel that gets you started is powered by your car battery. It also assists in providing power to your lamps, indicators, navigation system, dash-cams, windscreen wipers, and electric windows, as well as a variety of other on-board electrical features. Car batteries have a three to five-year average life span, assuming they're the right size for your vehicle; the wrong size can lead to unreliability and frequent breakdowns. The size can prefer to physical size of batteries. But we often difficult to different each batteries because it has similar size. But, the container of battery of course different. There are two things that refer to battery sizing. 1.  Battery Amp Hour The amperage hour rating is used to
