SPARK PLUG


 Introduction:

Spark Plug is a device which generate the spark within the engine cylinder for ignition of the fuel.
For ignition of the fuel we want approximately 20,000 Volts. But as we know that in Two Wheelers only 6V or 12 V batteries are placed. Then from where we get 20,000 Volts. 







   
We get 20,000 Volts by using ignition Coil. Spark plug consists Ignition coil.

Ignition Coil: The ignition coil is a pulse transformer that transforms or steps up the low battery or generator voltage to the high voltage, necessary to jump the gaps at the spark plugs.

By using this coil voltage can be stepped up from 6V to 20,000 volts. This coil has a laminated core, around which is wrapped the primary winding, consisting of hundred turn of relatively heavy wire and the secondary winding which several thousand fine wire. The windings are properly insulated from each other. The ignition coil is sealed to prevent entry of moisture which would cause short circuiting within the coil.

RATCHET & PAWL MECHANISM

INTRODUCTION ·       This type of mechanism is used in producing intermittent rotary motion from an oscillating or reciprocating motion member. ·       The ratchet and pawl mechanism consists of a ratchet wheel and a pawl, as shown in figure. ·       The ratchet consists of a round gear or linear rack with teeth. ·       A pawl is a spring loaded member that engages the teeth of the ratchet the teeth of ratchet is uniform.  Theory of operation A ratchet consists of a round  gear   or linear  rack  with teeth. A pawl is a  spring-loaded member that engages the teeth of the ratchet. The teeth are uniform, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e., forward) direction , the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing on  it  into the depression between the teeth as it passes the tip of each tooth. When the t

Battery ignition system

Most of SI engine used battery ignition system. In this system a 6 volt or 12 volt battery used to produce spark. Passenger cars, light truck, motorcycles and large stationary engines are fitted with this system. Main Parts of battery ignition system:     Battery A battery is used to provide energy for ignition. It is work as storage of energy and charged by dynamo, which is driven by engine. It converts chemical energy to electric energy.   Ignition switch It is used to turn on and off the ignition system. Battery is connected to the primary winding of ignition coil by ignition switch and ballast resistor. Ballast resistor It is connected in series with primary winding to regulate current in primary winding. It is used to prevent injury due to overheating of ignition coil. It controls the current passes through primary winding. It is made by iron. Iron has property of increase electrical resistance rapidly by increase in tempera

Block diagram energy conversion in hydropower plant

Explain with the help of block diagram energy conversion in hydropower plant? A power generating station which uses the kinetic or potential energy of water for generation of an electrical energy is called hydroelectric power plant. Potential energy :  when water is stored at high level it has potential energy.                             The potential energy is function of difference of water level between  two points                                 The difference in level of water between two points is called water head. Kinetic energy:   water ,when it is in motion is known is kinetic energy. Theory of operation    The water comes from the dam or reservoir through the penstock is directed on the blades of turbine runner , creating a force on the blades .since the runner is spinning ,the force acts through a distance ,in this way energy is transferred from the water flow to the turbine . The turbine is coupled with generator hence
