ADVANTAGES AND DISADVANTAGES OF V6 AND A STRAIGHT CYLINDER MOTOR ENGINE.

Any time an engine has more than 6 cylinders, it will be manufactured as a V engine as a straight 8 or straight 10 will not fit in the engine compartment of the average vehicle today and I don't know of any V4 engines in use on vehicles these days.


  Inline Engine
 The inline engine also called I (eg. I6=inline 6 cylinder) because all of the cylinders are inline with each other and the pistons are vertical.
 An inline engine can easily accommodate an odd number of cylinders such as 5 cylinder engine or the 3 cylinder engines that may be used in small fuel efficient models.
 An inline 6 will be cheaper to build than a V6 engine and there can be less complications in this 6 as there is one engine head for the timing belt or chain to connect to.





 V Engine
  This type of engine, if viewed from the front will resemble a V as the pistons are not vertical, they are slant on either side of the engine. Each side or bank of the engine has it's separate engine head and camshafts. The V will be different angles in different engines but the common angles are 45, 60 and 90 degrees.

The V engine produces more torque at lower RPM (Revolution Per Minute) ranges probably because of the power stroke coming from 2 sides of the crankshaft.

The V engine is also a compact engine per cylinder. The length required to house an inline 6 cylinder engine will house a V12 cylinder engine.

The width of a V engine is wider but not considerably wider and not so wide that it cannot fit in an engine bay. A W engine (Buggati uses it fot their monstrosity of a thing theycall a Veyron :P) is wider than a V engine and it still fits comfortably in the engine bay of some of the larger cars.

The bottom line is both engines are effective as both engines are used on high performance models with the various advantages of both not really doing much to pose a threat on the existence of the other.

Workshop Tools And Their Real Uses.

Workshop Tools And Their Real Uses.

1. DRILL PRESS: A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it smacks you in the chest and flings your beer across the room, splattering it against that freshly painted part you were drying.

2. WIRE WHEEL: Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also removes fingerprint whorls and hard-earned guitar calluses in about the time it takes you to say, "Damn!!!"

3. ELECTRIC HAND DRILL: Normally used for spinning pop rivets in their holes until you die of old age

4. PLIERS: Used to round off hexagonal bolt heads.

5. HACKSAW: One of a family of cutting tools built on the Ouija board principle: It transforms human energy into a crooked, unpredictable motion, and the more you attempt to influence its course, the more dismal your future becomes.

6. VISE GRIP PLIERS: Used to round off bolt heads. If nothing else is available: also used to transfer intense welding heat to the palm of your hand.

7. OXYACETYLENE TORCH: Used almost entirely for setting various flammable objects in your shop on fire. Also handy for igniting the grease inside a wheel hub you're trying to get the bearing race out of.

8. WHITWORTH SOCKETS: Once used for working on older British cars and motorcycles, they are now used mainly for impersonating that 14 or 13mm socket you've been searching for the last 15 minutes.
 9. HYDRAULIC FLOOR JACK: Used for lowering an automobile to the ground after you have installed your new disk brake pads, trapping the jack handle firmly under the bumper.

10. EIGHT-FOOT LONG DOUGLAS FIR 4X4: Used to attempt to pry an automobile upward off a hydraulic jack handle.

11. TWEEZERS: A tool for removing splinters of wood, especially Douglas fir.

12. TELEPHONE: Tool for calling your neighbor to see if he has another hydraulic floor jack.

13. SNAP-ON GASKET SCRAPER: Theoretically useful as a sandwich tool for spreading mayonnaise; used mainly for removing dog feces from your boots.

14. E-Z OUT BOLT AND STUD EXTRACTOR: A tool that snaps off in bolt holes and is ten times harder to remove than any known drill bit.

15. TWO-TON HYDRAULIC ENGINE HOIST: A handy tool for testing the tensile strength of motor mounts, shift linkage and fuel lines you forgot to disconnect.

16. CRAFTSMAN 1/2 x 16-INCH SCREWDRIVER: A large motor mount prying tool that inexplicably has an accurately machined screwdriver tip on the end without the handle.

17 AVIATION METAL SNIPS: (See hacksaw)

18. TROUBLE LIGHT: The home builder's own tanning booth. Sometimes called drop light, it is a good source of vitamin D, "the sunshine vitamin," which is not otherwise found under cars at night. Health benefits aside, its main purpose is to consume 40-watt light bulbs at about the same rate that 105-mm howitzer shells might be used during, say, the first few hours of the Battle of the Bulge. More often dark than light, its name is somewhat misleading. Might be a Lucas product. 
19. PHILLIPS SCREWDRIVER: Normally used to stab the lids of old-style paper-and-tin oil cans and squirt oil on your shirt; can also be used, as the name implies, to round off the interiors of Phillips screw heads.

20. AIR COMPRESSOR: A machine that takes energy produced in a coal-burning power plant 200 miles away and transforms it into compressed air that travels by a leaking hose to an pneumatic impact wrench that grips rusty bolts last tightened 70 years ago by someone at Ford, and rounds them off.

21. PRY BAR: A tool used to crumple the metal surrounding that clip or bracket you needed to remove in order to replace a 50 cent part.

22. HOSE CUTTER: A tool used to cut hoses 1/2 inch too short.

23. HAMMER: Originally employed as a weapon of war, the hammer now-a-days is used as a kind of divining rod to inadvertently locate expensive parts near to the object we are actually trying to hit.

24. MECHANIC'S KNIFE: Used to open and slice through the contents of cardboard cartons delivered to your front door; works particularly well on boxes containing upholstered items, chrome-plated metal, plastic parts and the hand not holding the knife.

25. SAFETY GOGGLES: Eye protection that is never worn because you can't find them when you are working under a car, trying to hammer off a rusted bolt while the rust flakes themselves embed into your one remaining good eye.

26. PNEUMATIC GREASE GUN: a tool that once you are situated under your vehicle, having moved the air hose from under the creeper wheels and is now hanging onto the Zerk fitting, and once the trigger is pulled you find that the grease cartridge is empty and it has been empty the last five times when you tried to use it then.

27. AIR CHISEL: A tool that when being used to gently cut into a piece of thin metal, decides that the "teaser-button" will now go to "full-hammer", shooting the part out the garage door and into traffic lanes only to get run over by an 18-wheeler.

28. TRANSMISSION FILL FUNNEL: A tool that when used correctly will overflow after the first 1/2 quart of oil, ATF or coolant, dumping the fluid on the engine, in the distributor, all over the fan belts or down the air intake.
