SYNOPSIS
Fuel power inevitably finds a very important role in the development of the plant’s economy and technical growth. Inspire of their high thermal efficiency, one cannot ignore the fact about the effect of their exhaust, in the atmosphere. It is a well-known fact that the toxic gases emitted in petrol engines are less than the engines. Due to high cost of petrol engines are more in use. Anticipating the use of petrol engines, even more in the near future; this system developed can be used to control the toxic gases, coming out of the petrol engines.
These toxic gases are harmful not only to the atmosphere, but also to the human & animal race. Objective of this project is to design & fabricate a simple system, where the toxic levels are controlled through electronic ignition control system. This system senses the cam position and electronic ignition is given two times in certain periodic interval per stroke so that the hydro carbon emission to be controlled.
INTRODUCTION
The primary of the ignition coil is connected to the battery and when the contact breaker trips the connection, a voltage of about 400V is produced across the primary. This 400V is stepped up to about 40kV and used to produce a spark in the spark plug. All this is fairly simple when you have a 12V battery which can supply the current taken by the ignition coil, normally about 2.5 Amps.
The sensor is fixed to the engine head which is detecting the cam position and this signal is given to the electronic ignition system. The electronic ignition control system is gives two times the spark plug in certain interval of time so that the all the fuel inside the chamber to be fired. In that case the exhaust gas to be pure when compared to normal ignition of the two stroke petrol engine.
ADVANTAGES
Improves engine efficiency due to multiple sparks
Decrease load on Battery
Starts even when the battery voltage is 8 Volt.
Fuel efficiency of the engine is increased.
To reduce the emission
All the power to be utilized so that efficiency is increased
DISADVANTAGES
Additional Cost is required for Electronic Ignition Circuit
APPLICATION
