Understanding the piston and its function in detail

PISTON

A piston is a sliding plug that is installed inside a combustion engine cylinder in a hydraulic, pneumatic and pump cylinder.

The purpose of the piston in the cylinder is:

 Changing the volume of the cylinder contents, changes in volume can be caused because the piston gets pressure from the contents of the cylinder or vice versa the piston presses the contents of the cylinder. Pistons that receive pressure from the fluid and will change the pressure into a (linear) force.

*Open and close the flow path.

With this function, the piston must be mounted tightly in the cylinder. One or several rings (rings) are mounted on the piston to be very tight with the cylinder. In cylinders with middle to upper working temperatures, the ring material is made of metal, called the piston ring (piston ring). Whereas in cylinders with low working temperatures, generally ring material is made of rubber, called the ring seal (seal ring).

A piston is a machine component that forms a combustion chamber together with a cylinder block and cylinder head. The piston also makes up and down movements to carry out the engine work cycle, and the piston must be able to continue the combustion power to the crankshaft. So we can see that the piston has a very important function in carrying out the work cycle of the engine and in producing combustion power. For this reason, the piston must have the following conditions:

Light, to make it easy for the engine to reach high rotation. If the piston construction is too heavy, it is difficult for the engine to reach high rotation, so the acceleration of the motorbike or the car becomes very slow... Or the language is easy, the motorbike or car is slow to reach high speeds even though the gas has been pulled.

Resist explosion pressure due to combustion results. At the time of business steps, gasoline and air were burned by electric sparks from the spark plug. The results of this combustion will cause explosions and very strong pressure in the combustion chamber, not least the piston receives the explosion and pressure from the combustion results.. Therefore, in addition to the piston must be light but the piston must also be strong in resisting explosions and the pressure of combustion to continue moving the shaft 

Crank.

Resistant to expand. Combustion of a mixture of gasoline and air in the combustion chamber will cause heat, the temperature in the combustion chamber area will rise very high. As we have seen that with increasing temperatures, the metal will undergo a change in shape or expand. Pistons made of special metals will experience a lot of expansion. If the expansion experienced by the piston is excessive it will make the piston locked or fastened to the cylinder block wall, so that the piston will stop working up and down in the cylinder, so that it can be said that the engine has died with the piston stopped in doing up and down movements.

The piston (piston) functions to move the energy obtained from the results of combustion to the crankshaft. At the piston there are complementary components, namely:

- Connecting rod (connecting rod to connect the piston to the crankshaft).

- Piston pen (piston pin), to tie the piston to the connecting rod through the bushing hole

- The piston ring (piston ring), functions to form a tight seal against gas leakage between piston and cylinder slits while regulating the lubrication of piston and cylinder walls.

- The piston ring consists of a compression ring and lubricating ring.

- The crankshaft, which functions to change the piston's alternating motion into a rotary motion which is then used to rotate the wheel. The crankshaft is equipped with bearings which function to avoid friction between the axle

- Crank with other rotating parts. The crankshaft part that supports the piston is inserted by a sliding bearing called the metal road, while the crankshaft part which supports the engine block is inserted by a sliding bearing called metal siding.

- Flywheel or successor wheel, functions to receive some of the energy obtained from the work step and gives energy to other steps. On the outside of the flywheel a ring gear is installed, this gear is used to relate to the pinion gear on the starter motor when the engine is turned on.

The function of the piston is to receive pressure from the combustion of the gas mixture and continue the pressure to rotate the crank shaft through the connecting rod.

Modification of Manual Transmission So Matic

Smart Solutions Upgrade Manual Car Transmission Into Automatic Transmission

MODIFICATION

Congestion in the capital city of Jakarta, which is getting more and more severe, plus an increase in the population of motorized vehicles that are difficult to contain makes big cities a paradise for traffic congestion. For most ordinary people, the distance to the office far enough from where they live is looking for the best solution to reduce the fatigue of driving during traffic jams by replacing cars that transmit automatically, aka Automatic Transmission.

1. Gearbox Matic Release Ex. Singapore

Mathias Bekas Ex. Singapura / Japan copying form from Toyota Vios Matic is still in good condition

One component of the "innards" of the transmission gearbox consists of several clutch lining sheets which are immersed in ATF (Automatic Transmission Fluid) oil so that the service life is longer

The figure of the I-DSI Machine belonging to the Honda Jazz / Honda City Gen.1 is still integrated with the 7-Accelerated CVT Tiptronic Matic Gearbox

What does it mean Matic Gearbox without Matic Gear Shift or Matic Transmission Lever

Accessories Pelengkap Gearbox Matic Copotan:

1. ECU & Wiring Harness Bawaan Mesin Bertransmisi Matic  

A manual injection transmission car (DOHC / VVT-i) is usually equipped with ECU (Electronic Control Unit), but if you want to upgrade your car's manual transmission to an automatic transmission, you also need to replace the Car Transmission Automatic ECU because the data/program is different.

2. Gear Shift & Pedal Set 

Already buying removable gearbox, buying the following ECU Wiring Harness, don't forget the Gear Shift Automatic component so that the vehicle can run normally like an automatic car.

If previously the manual transmission car had 3 pedals; Gas, brakes and clutches, after you upgrade to the gearbox, you must also remove the clutch pedal, and replace the brake pedal with the wider size of the thematic car.

3. Speedometer with Gear Shift Indicator

The option to replace the Speedometer that has the Gear Shift Indicator belongs to the car mats is not a mandatory menu depending on the budget requirements prepared by the car owner. But if you are the type of person who prioritizes practicality & safety-oriented during driving, the Automatic Gear Shift Indicator feature on the Speedometer can prevent you from focusing wrongly or incorrectly moving the transmission lever which can have fatal consequences for other road users' safety.

Advantages of Upgrading Gearbox Matic Ex. Singapore / Japan:

→ The price offered for lightweight modification to Automatic Transmission uses Ex-Split Matic Gearbox Ex / Singapore / Japan estimates to cost up to no more than IDR 8,000,000 * (* installation on Vios Limo Ex. BB) is much more rational than you buy Gearbox Matic a new status as an authorized ATPM workshop that can touch the 30 million number not including supporting accessories and installation.

→ The price of the material following the installation is still in the friendly category in the bag, less than 8 million, instead you have to struggle to sell your old manual transmission and then buy another second car, automatic transmission from the brand and the same year of manufacture.

→ Plug & Play Guarantee. At present the majority of Japanese manufacturers make several car models with the same engine type choices on the basis of production efficiency. Examples of Suzuki K14B engines are used in 3 types of cars on the same platform; Suzuki Swift, Suzuki SX4, and Suzuki Ertiga, as well as Toyota 1NZ-FE engines,  are also used in 3 different types of cars; Toyota Vios, Yaris, and Limo.

→ If your car is Vios Limo Ex. The Blue Bird Taxi has a 1NZ-FE engine code, so look for the gearbox from the same engine with Vios Matic's 1NZ-FE type to make it easier to install when you have to mate the default engine with a gearbox with a copy.

→ Guaranteed good condition is worth using. Although the status of "used" gearboxes, but it is necessary to know that the condition is 70-80% still feasible because the hours of flying cars in Singapore & Japan are considerably less because the country is small and the level of mobilization is lower compared to cars in developing countries.

→ According to its function as an automatic clutch, the benefits obtained are Feel Convenience through traffic jams in busy hours every day.

→ Good Value for Money. Manual Transmission upgrades to Matic provide added value can lift the market price of your car if one day you want to resell it.

Kelemahan Gearbox Matic Captain Ex. Singapura/ Japan:

→ The name of the conventional 4-speed Matic gearbox is definitely the business of pulling down (initial acceleration) to be less responsive than still adhering to a 6-speed manual transmission. Of course, you as a person in control behind the wheel must be able to adapt to the characteristics of the car automatically.

→ Fuel consumption will be slightly more wasteful than normal conditions when still using a manual transmission gearbox. If the average consumption in the City of Vios Limo Ex.BB manually transmits can penetrate 1:13 km / l then if it has been applied to conventional 4-speed automatic transmission only able to achieve fuel efficiency in the range 1:10 - 1:11 km / l just because the car mats has to do gearshift at the engine speed is quite high.

→ The cost of routine maintenance of an automatic transmission is more expensive than a manual transmission. If usually when you are still using a manual transmission, you only need to replace 3 liters of transmission oil, with the Matic gearbox you have to drain Matic transmission oil with a volume of 8 liters up to 10 liters every 30,000 km mileage. Plus the price per liter of Matic transmission oil is more expensive than manual transmission oil. If you neglect to change the transmission oil Matic, it is possible for a clutch to slip when there is a shift of gear at each engine speed.

→ It is natural from birth, a 4-speed automatic transmission cannot be pushed if it suddenly experiences a Soak battery. At a minimum, you have to do a battery jumper with another car or contact the nearest battery store to buy a new battery.

Pengertian dan Fungsi Karburator

Pengertian dan Fungsi Karburator

A. Pengertian dan Fungsi Karburator

      Karburator merupakan bagian terpenting dari sepeda motor. Hampir semua sepeda motormenggunakan karburator karena umumnya sepeda motor menggunakan bensin sebagai bahan bakar. 

     karena itu karburator yang baik harus mampu membuat gas yang sempurna dan sesuai dengan kebutuhan mesin. untuk mendapatkan pembakaran sempurna di butuhkan perbandingan mesin dan udara dalam pencampuran gas, menurut teoritis adalah 1:15 artinya 1 gram bensin di campur dengan 15 gram udara.

    Apabila perbandingan campurannya lebih dari 1:15 misal 1:18 dikatakan campuran miskin 1:12 di katakan campuran kaya.

(putar kekanan mentok putaran  360 derajat dan kembalikan kekiri hingga 2 – 3 putaran sampe ke temu putaran mesin yang paling  stabil).- Kemudian kecilkan RPM dengan memutar baut penyetel langsam kekiri hingga ditemukan  1200 - 1300 RPM, dengan melihat jarum penunjuk pada Tachometer. 

SEJARAH karburator

 

          Karburator pertama kali ditemukan oleh Karl Benz pada tahun 1885 dan dipatenkan pada tahun 1886. Pada tahun 1893 insinyur kebangsaan Hungaria bernama János Csonka dan Donát Bánki juga mendesain alat yang serupa. Adalah Frederick William Lanchester dari Birmingham, Inggris yang pertama kali bereksperimen menggunakan karburator pada mobil. Pada tahun 1896 Frederick dan saudaranya membangun mobil pertama yang menggunakan bahan bakar bensin di Inggris, bersilinder tunggal bertenaga 5 hp (4 kW), dan merupakan mesin pembakaran dalam (internal combution). Tidak puas dengan hasil akhir yang didapat, terutama karena kecilnya tenaga yang dihasilkan, mereka membangun ulang mesin tersebut, kali ini mereka menggunakan dua silinder horisontal dan juga mendisain ulang karburator mereka. Kali ini mobil mereka mampu menyelesaikan tur sepanjang 1.000 mil (1600 km) pada tahun 1900. Hal ini merupakan langkah maju penggunaan karburator dalam bidang otomotif.        Karburator umum digunakan untuk mobil berhahan bakar bensin sampai akhir 1980-an. Setelah banyak kontrol elektronik digunakan pada mobil, penggunaan karburator mulai digantikan oleh sistem injeksi bahan bakar karena lebih mudah terintegrasi dengan sistem yang lain untuk mencapai efisiensi bahan bakar.

Sistem Operasi Karburator

Dalam operasinya sendiri, maka sebuah karburator harus bisa mengatur jumlah aliran udara saat memasuki ruang bakar, mencampur bahan bakar dan aliran udara secara sempurna dengan rata dan mendistribusikan bahan bakar pada jumlah yang sesuai seperti aliran udara masuk menuju ruang bakar, dengan begitu rasio udara atau bahan bakar pun tetap terjaga.

Hal tersebut akan mudah dilakukan bila udara dan bensin merupakan fluida ideal. Namun kenyataannya, melalui sifat alami yang dimiliki oleh kedua fluida ini yakni dengan adanya inersia fluida, gaya gesek fluida, viskositas dan lainnya, maka karburator pun menjadi lebih kompleks untuk mengatasi kondisi ketidak idealan fluida tersebut.

Tak hanya itu saja, karburator pun harus tetap bisa memproduksi campuran antara udara/bensin dengan tepat pada kondisi apapun. Sebab karburator mesti beroperasi dengan putaran mesin, temperatur, gaya sentrifugal dan tekanan udara yang begitu beragam. Dalam hal ini, karburator wajib beroperasi pada kondisi start keadaan panas, start mesin keadaan dingin, berjalan dengan putaran rendah, akselerasi saat membuka gas tiba-tiba, kecepatan stabil pada gas yang sebagian terbuka dengan jangka panjang dan kecepatan tinggi pada gas yang terbuka penuh. salam speed Uplixspeed
