Review of Short Phrases and Links

    This Review contains major "Crankshaft"- related terms, short phrases and links grouped together in the form of Encyclopedia article.


  1. A crankshaft is a pretty substantial chunk of metal arranged in a highly contorted shape.
  2. Crankshaft is an eponymous comic strip about an elderly, curmudgeonly school bus driver which debuted on June 8, 1987.
  3. The crankshaft is a modular-iron casting with eight counterweights for excellent balance.
  4. The crankshaft is a long, iron or steel shaft mounted rigidly in the bottom of the crankcase, at a number of points (usually 4-7).
  5. The crankshaft is a rotating mass, and any rotating mass that isn't perfectly balanced will cause uneven loading on the bearing surfaces that support it.


  1. While these weights can balance the crankshaft completely, they cannot completely balance the motion of the piston, for two reasons.
  2. The combustion process pushes the piston down the cylinder with great force turning the crankshaft to provide the power to propel the vehicle.
  3. A straight two engine may have a simple single-throw crankshaft, with both pistons at top dead centre simultaneously ( parallel twin).
  4. As a piston moves back and forth, a connecting rod changes its angle; its distal end has a rotating link to the crankshaft.
  5. In the Wankel engine, the rotors drive the eccentric shaft, which can be considered the equivalent of the crankshaft in a piston engine.

Power Stroke

  1. By the time the crankshaft completes two revolutions, each cylinder in the engine will have gone through one power stroke.
  2. When the air-fuel mixture burns, the power stroke now has a better 'leverage' on the crankshaft and this helps to extract more power out of the combustion.


  1. The combustion is started by the spark plug some 5 to 40 crankshaft degrees prior to top dead center (TDC), depending on engine speed and load.
  2. The position closest to the crankshaft is known as bottom dead centre ( BDC).


  1. If the crankshaft is heavy, metal is removed by drilling or grinding the counterweights.
  2. The crankshaft does not need counterweights, but the engine does need a heavier flywheel than a 90-degree V-twin engine does.
  3. Some expensive high performance crankshafts also use heavy metal counterweights to make the crankshaft more compact.


  1. A balancer shaft transfers its force via bearings onto the crankshaft and rather increases tear.
  2. After drilling, the crankshaft is again spun on the balancer to determine if additional corrections are required.

Every Two

  1. Each valve opens only once during the four-stroke cycle; that is, the camshaft makes one rotation for every two rotations of the crankshaft.
  2. A single cylinder provides only one power impulse every two crankshaft revolutions in a four-cycle engine.

Oil Pan

  1. The oil pump is mounted at the bottom of the engine in the oil pan and is connected by a gear to either the crankshaft or the camshaft.
  2. In the Wankel engine, the oil pan is also mandatory for crankshaft, bearings, gears lubrication and thermalization.


  1. The crankshaft is located below the cylinders on an in-line engine, at the base of the V on a V-type engine and between the cylinder banks on a flat engine.
  2. Two banks of three cylinders are arranged at a 15- axial angle from the crankshaft.


  1. In a Crankshaft comic, you could see the skyline of Downtown Cleveland come into view as Ed Crankshaft takes students on a field trip.
  2. Written by Tom Batiuk and drawn by Chuck Ayers, Crankshaft is a spinoff from Batiuk---s comic strip Funky Winkerbean.


  1. If the engine has a crankshaft, then the crank pins are the journals of the off-centre bearings of the crankshaft.
  2. Some bearings may depend on oil splashed from the bottom of the crankcase by the turning crankshaft.
  3. When describing a crankshaft design, the number of main bearings is generally quoted, as the number of crank pins is determined by the engine configuration.
  4. In a piston engine, the main bearings are the bearings on which the crankshaft rotates, usually plain or journal bearings.

Half Crankshaft

  1. The pump assembly consists of a pump that pressurizes the fuel and a disc-shaped valve that rotates at half crankshaft speed.
  2. Flywheel A 4 cylinder engine produces a power stroke every half crankshaft revolution, an 8 cylinder, every quarter revolution.

Td Font-Size

  1. TD {font-size:10pt} crankshaft - Hutchinson encyclopedia article about crankshaft Printer Friendly 908,456,509 visitors served.
  2. TD {font-size:10pt} crankshaft - definition of crankshaft by the Free Online Dictionary, Thesaurus and Encyclopedia.


  1. The camshafts are located in a vertical plane above the crankshaft and parallel to its center of rotation.
  2. The reciprocating motion of the pistons is translated into crankshaft rotation via connecting rods.
  3. In other words, two-cycle engines operate on 360 degrees of crankshaft rotation, whereas four-cycle engines operate on 720 degrees of crankshaft rotation.
  4. If you follow the firing order of your motor, you'll only have to turn the crankshaft one complete rotation.

Engine Block

  1. Sump The space in the engine block under the crankshaft into which the oil drains from its various applications.
  2. Cylinder Block - Engine block, the actual block where the cylinders are bored out, the camshaft and lifter valley exists, and the crankshaft web is located.

Older Engines

  1. Older engines make use of a mechanical fuel pump and valve assembly that is driven by the engine crankshaft, usually from the timing belt or chain.
  2. Older engines used a camshaft located in the sump near the crankshaft.

Crankshaft Spins

  1. The intake tract is opened and closed by a thin disk attached to the crankshaft and spins at crankshaft speed.
  2. As the crankshaft spins, it turns the camshaft, which in turn opens the intake and exhaust valves in sequence.


  1. The camshaft is driven by the crankshaft through timing belts, gears or chains.
  2. It has custom teeth to turn the camshaft(s) synchronized with the crankshaft and is specifically designed for a particular engine.
  3. Long rods connect the crosshead to the crankshaft, on which is fixed the flywheel.
  4. To keep the combustion pulses from generating a vibration, a flywheel is attached to the back of the crankshaft.
  5. In most engines, this is done by a "Timing Chain" (similar to a bicycle chain) that connect the camshaft with the crankshaft.

Four-Stroke Engine

  1. A four-stroke engine requires that the valves open and close once every other turn of the crankshaft.
  2. For a four-stroke engine, key parts of the engine include the crankshaft (purple), one or more camshafts (red and blue), and valves.


  1. The Atkinson cycle allows the intake, compression, power, and exhaust strokes of the four-stroke cycle to occur in a single turn of the crankshaft.
  2. Therefore, Crankshaft sold an extensive collection of movie posters to set up a fund so they could attend college after graduation.
  3. A crankshaft with only two ounce-inches of imbalance at 2,000 rpm will be subjected to a force of 14.2 lbs.
  4. The flat twin, or boxer configuration, has a longitudinal crankshaft with the cylinders protruding horizontally from either side of the engine.
  5. One supporting the crankshaft, allowing it to rotate with minimum whip.


  1. With its crankpin offset of 18 degrees, the V10 fires at the ideal spacing of 72 degrees crankshaft angle.
  2. The crossplane crankshaft has four crankpins, each offset at 90-- from the adjacent crankpins.
  3. The Toyota 2AZ-FE engine crankshaft is offset 10mm to the thrust side of the cylinder bore centre line.


  1. The JUN FULL COUNTER CRANKSHAFT is a genuine crankshaft with both the counter weight of ideal form and the excellent balance.
  2. Both have advantages in terms of performance, as a shorter and more stable crankshaft will produce better engine balance.


  1. The crossplane V8 can be balanced with counterweights on the crankshaft.
  2. If the crankshaft is for an externally balanced engine (such as a big block Chevy), the balancing will be done with the flywheel and damper installed.
