Requirement of the ignition system and ignition/firing order in the IC engine

The ignition system is the most important part of the SI engine (spark ignition engine). Different types of ignition systems are used in the Internal Combustion SI engine. Ignition system used to ignite air-fuel mixture at the proper time and in a well suitable manner with the wild range of engine speed. A requirement of the ignition system Ignition system mainly needed in an engine due to the following reasons. It should provide a good spark between the electrodes of the plug at the correct timing. The ignition system should function efficiently over the entire range of engine speed continuously. Also, it should be light, effective, and reliable in service. It should be compact and easy to maintain. It should be cheap and convenient to handle. The interference from the high voltage source should not affect the functioning of the radio and television receivers inside an automobile. Firing order in the IC engine The order in which various cylinders of multiple cylinder engine fire is c...

Type of ignition systems in IC Engine

The ignition system is the most important part of the SI engine (Spark Ignition Engine). The ignition system an important system used in the Internal Combustion engine. Ignition system used to ignite air-fuel mixture at the proper time and in a well suitable manner with the wild range of engine speed. Battery Coil Ignition System The essential component of the battery ignition system is, Battery  Ignition switch Distaibıde Ignition coil with ballast resistor Spark plus The ignition switch provided connects and disconnects the ignition system from the berry so, the engine can be started or stopped. When the ignition catch is on, the contact breaker points are closed, then the current to flow from the battery through the primary winding of the ignition back to the battery through earthing. It developer o magnetic field across the primary winding of the ignition and inducer back which oppose the battery current. A voltage is always induced in the secondary winding load but emf is too ...

Ex: 01 To study valve timings for four stroke petrol/Diesel Engines.

 The valve timing analysis is one of the most important studies in IC engine development. Based on Valve timing analysis, engine performance,  fuel requirement and stock timing can be studied and improved. the following experiment shows the study of valve timing study for petrol and diesel engine. EXPERIMENT NO: 01 AIM: To study valve timings for four-stroke petrol/Diesel Engines. APPARATUS: Models and cut sections of four-stroke petrol/Diesel Engine. Measuring tape Chalk Piece of paper Theory and Description: The diagram which shows the position of the crank of a four-stroke cycle engine at the beginning and at the end of suction, compression, expansion, and exhaust of the engine are called the Valve Timing Diagram. The extreme position of the bottom of the cylinder is called "Bottom Dead Centre". In the case of horizontal engines, this is known as "Outer Dead Centre". The position of the piston at the top of the cylinder is called "Top Dead Centre". In ...
