LG V10

The LG V10 is an Android smartphone manufactured by LG Electronics. Announced in September 2015 and released in October 2015, the device shares many similarities with the earlier LG G4. Its main feature is a customisable second display above the primary display, which, among other uses, shows notifications and music controls without waking up the primary display.

Hardware

The V10 uses the same camera as the LG G4. The phone has a 2560x1440 Quantum IPS display, a silicone back with a removable battery and SD Card expansion, a six core Qualcomm Snapdragon 808 processor which sports a big.LITTLE architecture similar to the 810, and 4GB of LPDDR3 933Mhz RAM. The camera is 16 megapixels and includes Optical Image Stabilization with manual DSLR-like modes for video and still shots. There are two front 5 megapixel cameras for widescreen "groupies". The phone supports Qualcomm's Quick Charge 2.0 technology via USB and Qi wireless charging via the optional CPR-120 wireless charging cover.

Reception

V10 engine

A V10 engine is a V engine with 10 cylinders in two banks of five. It is longer than a V8 engine but shorter than a straight-6 engine or V12 engine.

Mechanics

The V10 is essentially the result of mating two even-firing straight-5 engines together. The straight-5 engine shows first and second order rocking motion. Here it should be assumed that the crankshaft with low second-order vibration is used and the first order is balanced by a balance shaft. By mating the straight-5 banks at 90 degrees and using five throws, the balance shafts balance each other and become null. The firing sequence is odd (BMW S85, Dodge Viper, Volkswagen Touareg). Using an 18° split journal crankshaft the firing order can be made even, and the two balanced shafts do not balance each other completely, but are combined into a single very small balance shaft (Lamborghini V10, Porsche Carrera GT). Using a five-throw crankshaft and 72° bank angle the firing order can be made even, and the two balanced shafts do not balance each other completely, but are combined into a single small balance shaft (Toyota 1LR-GUE engine). A 36° degree bank angle and a 108° flying arm crankshaft would allow even firing without a balance shaft and smaller counterweights, but would be impractical.
