V12 engine

V12 engine

  A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft.[1]
Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts. A V12 with two banks of six cylinders angled at 60°, 120° or 180° (with the latter configuration usually referred to as a flat-12) from each other has even firing with power pulses delivered twice as often per revolution as a straight-6. This allows for great refinement in a luxury car. In a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large displacement, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life.




Aviation

 The first V12 engines were used in aircraft. By the end of World War I, V12s were popular in the newest and largest fighters and bombers and were produced by companies such as Renault and Sunbeam. Many Zeppelins had 12-cylinder engines from German manufacturers Maybach and Daimler. Various U.S. companies produced the Liberty L-12; the Curtiss NC Flying boats, including the four V12 engine powered NC-4, the first aircraft to make a transatlantic flight.
V12 engines reached their apogee during World War II. Fighters and bombers used V12 engines such as the British Rolls-Royce Merlin and Griffon, the Soviet Klimov VK-107, the American Allison V-1710, or the German Daimler-Benz DB 600 series and Junkers-Jumo. These engines generated about 1,000 hp (750 kW) at the beginning of the war and above 1,500 hp (1,100 kW) at their ultimate evolution stage. The German DB 605D engine reached 2,000 hp (1,500 kW) with water injection. In contrast to most Allied V12s, the engines built in Germany by Daimler-Benz, Junkers-Jumo, and Argus (As 410 and As 411) were primarily inverted, which had the advantages of lower centers of gravity and improved visibility for single-engined designs. Only the pre-war origin BMW VI V12 of Germany was an "upright" engine. The United States had the experimental Continental IV-1430 inverted V12 engine under development, with a higher power-to-weight ratio than any of the initial versions of the German WW II inverted V12s, but was never developed to production status, with only 23 examples of the Continental inverted V12 ever being built.
The Rolls-Royce Merlin V12 powered the Hawker Hurricane and Supermarine Spitfire fighters that played a vital role in Britain's victory in the Battle of Britain. The long, narrow configuration of the V12 contributed to good aerodynamics, while its smoothness allowed its use with relatively light and fragile airframes. The Merlin was also used in the Avro Lancaster and de Havilland Mosquito bombers. In the United States the Packard Motor company was licensed by Rolls-Royce to produce the Merlin as the Packard V-1650 for use in the North American P-51 Mustang. It was also incorporated into some models of the Curtiss P-40, specifically the P-40F and P-40L. Packard Merlins powered Canadian-built Hurricane, Lancaster, and Mosquito aircraft, as well as the UK-built Spitfire Mark XVI, which was otherwise the same as the Mark IX with its British-built Merlin.
The Allison V-1710 was the only indigenous U.S.-developed V12 liquid-cooled engine to see service during World War II. A sturdy design, it lacked an advanced mechanical supercharger until 1943. Although versions with a turbosupercharger provided excellent performance at high altitude in the Lockheed P-38 Lightning, the turbosupercharger and its ductwork were too bulky to fit into typical single-engine fighters. While a good performer at low altitudes, without adequate supercharging, the Allison's high-altitude performance was lacking.
After World War II, V12 engines became generally obsolete in aircraft due to the introduction of turbojet and turboprop engines that had more power for their weight, and fewer complications in large aircraft.





WINDOWS 7 TUTORIAL

Meningkatkan Performa Windows 7

Windows 7 merupakan produk windows terbaru dari microsoft. Secara default windows 7 menawarkan banyak  fitur yang sebenarnya tidak diperlukan oleh pengguna komputer desktop (perorangan). Jika fitur-fitur yang tidak terlalu penting tersebut di nonaktifkan atau dimatikan, maka bisa lebih meningkatkan performa windows 7 . Yang kita bahas disini bukanlah mengupgrade hardware, tetapi melakukan konfigurasi pada software windows.Karena jika melakukan upgrade hardware komputer yang membutuhkan biaya , sedangkan disisi lain bagi yang tidak punya biaya upgrade,  dapat meningkatkan kinerja windows dengan sedikit memodifikasi konfigurasi defaultnya.

Berikut ini beberapa tips untuk mempercepat /meningkatkan performa windows 7

  1. Disable / menonaktifkan service windows yang tidak perlu, seperti: Menonaktifkan autoplay/autorun di windows 7, Cara Uninstal Tablet PC component di windows 7, Cara menonaktifkan (disable) automatic update di windows 7, Mempercepat tampilan menu di start menu windows 7, Menonaktifkan (disable) telephony service di windows 7, Menonaktifkan (disable) fax service di windows 7, Menonaktifkan (disable) error reporting windows 7 dll
  2. Menambah virtual memory windows
  3. Jika ukuran hardisk besar, sebaiknya bagi ruang hardisk menjadi beberapa bagian melalui partisi hardisk
  4. Lakukan scandisk dan defrag menggunakan disk defragmenter secara berkala . Dengan melakukan scandisk dan defrag secara berkala dapat membantu windows menandai sector dan cluster baik dan yang rusak di dalam ruang hardisk, serta dapat membantu windows mengurutkan dan mengelompokkan data-data yang disimpan di hardisk seperti file system, file aplikasi, dan file data agar lebih sesuai dengan kebutuhan system sehingga lebih mudah diakses oleh windows. 
  5. Membersihkan file sampah windows, seperti menghapus file temporer , file prefetch windows , membersihkan file registry yang rusak (error), menghapus thumbnail chace explorer , 
  6. Scan virus dan adware , malware dan spyware secara berkala serta jangan lupa update antivirus secara offline maupun secara online.
  7. Instal aplikasi secukupnya dll

WINDOWS 8

Windows 8 is the current release of the Windows operating system, produced by Microsoft for use on personal computers, including home and business desktops, laptops, tablets, and home theater PCs. Development of Windows 8 started before the release of its predecessor in 2009. Its existence was first announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.
Windows 8 introduces significant changes to the operating system's platform, primarily focused towards improving its user experience on mobile devices such as tablets to rival other mobile operating systems like Android and iOS, taking advantage of new or emerging technologies like USB 3.0, 4Kn Advanced Format, UEFI firmware, near field communications, cloud computing and the low-power ARM architecture, new security features such as malware filtering, built-in antivirus capabilities, a new installation process optimized for digital distribution, and support for secure boot (a UEFI feature which allows operating systems to be digitally signed to prevent malware from altering the boot process), the ability to synchronize certain apps and settings between multiple devices, along with other changes and performance improvements. Windows 8 also introduces a new shell and user interface based on Microsoft's "Metro" design language, featuring a new Start Screen with a grid of dynamically updating tiles to represent applications, a new App platform with an emphasis on Touchscreen input, and the new Windows Store to obtain and/or purchase applications to run on the operating system.
