Four Stroke Spark Ignition Engine In four stroke S.I engine the complete operation is done in four stroke in this each stroke has 180° of crankshaft rotation and this four stroke is completed by 720° of crank rotation. Intake stroke: In this stroke start when piston is at TDC and move towards BCD. In this …
THREAD MICROMETER 1) Thread micrometer is used to measure the pitch diameter of the screw thread and it shows the variation in drunken thread. 2)It Is equal to the ordinary micrometer, it is provided with contact point. 3) It has two ends one is connected with a spindle, and another end …
Nomenclature of screw thread: Nomenclature of screw thread: Nomenclature of screw thread represents the futures of screw, the main function of screws is to join/combine different metal/non-metals elements together. There are various types of screws for different types of joining, and the formation of threads is done by providing a helical grooves on a circular/cylindrical metal. …
Inversions of double slider crank chain Inversions of double slider crank chain: In this article we will learn about Inversions of double slider crank chain. In Inversions of double slider crank chain there are three important double slider crank chain. they are explained as follows. There are three important double Slider Crank Chain are: 1. Elliptical trammels …
Rotary internal combustion engine or Gnome engine: It consist of a seven cylinders in one plane and all revolve about a fixed center D, as shown in figure , rotary internal combustion is mostly used in aviation. But now a days gas turbine is used in that place. While Crank (link2) is fixed. In this …

Oscillating Cylinder Engine: The arrangement of the Oscillating Cylinder Engine is used to convert the reciprocating motion into a rotary motion. in this method there exist in a turning pair which is a fixed link. The link 3 is corresponds to the connecting rod of a reciprocating steam engine mechanism.
COUPLING ROD OF A LOCOMOTIVE OR DOUBLE CRANK MECHANISM The mechanism of a locomotive which consist of four links, in this mechanism the link AB and BC act as Crank , AB is a fixed points on the two wheels in which they are connected to the respective wheels. AB is used to maintain equal …
Aapproximate straight line mechanisms: This approximate straight line mechanisms are the modification of four bar chain mechanisms. They are explained as follows: 1.Watt’s mechanism 2.Grasshopper mechanism 3.Tchebicheff’s mechanism 1. Watt’s mechanism: It is used for early steam engines to set the piston rod in a cylinder to get a straight line motion approximate, this is …
Screw Jack: The screw jack is a device used for lifting heavy/huge loads, When we apply a smaller amount of effort on the handle to rotate the screw, this rotation used to move the rod in and out of the screw jack. this process is worked on the principle called inclined plane.as shown in figure …
Inversions of single Slider Crank shaft The single Slider Crank Chain is a four link mechanism. this is used for converting the circular rotation of crank link into straight line motion of piston rod in a cylinder. As we know that by fixing , turning etc.. With the help of different links in a kinematic …
