triple spark ignition system recent research paper pdf

Abstract

This paper describes some results of the research in the area of multiple spark ignition engines. Dual spark ignition
system has proved their potential in improving the performance of the engines and improved emissive characteristics as
compared with the single spark plug ignition system. Recently a new type engine has been introduced which uses triple
spark plugs at different location, controlled by an advanced electronic control unit. This advanced electronic control unit
uses three different ignition timings with variable spark plug number. Experiments were conducted at different load
conditions and different types of engines has proved that dual spark plug ignition engines are surely better than a single
spark plug engine ,but triple spark ignition engines has proved their potential. The current paper investigates the effect
of multiple spark plugs to single spark plug on the basis of engine performance and their respective emissive
characteristics. The result has shown that there is a considerable performance improvement in power output, increase in
thermal efficiency and reduced maintenance due to lower emission of BSFC, HC and CO emission in triple spark plug
mode of operation as compared to single and dual spark plug mode of operation..

Transducer can be used to enhance the working power of tripal spark ignition with minimum emmision of pollution which is the main motive of this project more technology less pollution to balance the mother nature..

Abstract - Today it is a common trend. It has become a fashion for the people especially living in urban areas to ride such
vehicles. Now the companies even want to launch such vehicles that attract the younger generation. This can be achieved
by technology known as DTSi. Due to DTSi (digital twin spark ignition) system it is possible to combine strong
performance and fuel efficiency. The improved engine efficiency modes have also resulted in lowered fuel consumption.
The efficiency of these small engines were enhanced with increased power output just by increasing the number of fuel
igniting element i.e. Spark Plug. Spark ignition is one of the most vital systems of an engine. Any variation in the spark
timing and number of sparks per minute affects the engine performance severely. Thus a good design and control of the
system parameters becomes most essential for optimum performance of an engine. Due to Digital Twin Spark Ignition
system it is possible to combine strong performance and higher fuel efficiency. DTSi offers many advantages over
conventional mechanical spark ignition system. In this paper we will get to know how mechatronics is useful in
instrumentation. Conventional engines employed a single spark plug in its engine for igniting the mixture of fuel and air.
But to have more effective burning of the mixture in order to increase the power output and reduce the wastage of this
mixture as unburnt, the number of spark plug was doubled for efficient burning of the mixture. Two spark plugs helped
in igniting the fuel from two directions rather than one, as in conventional engines. This new technology was termed as
“Twin Spark Ignition System”. Although this technological trend proved to be sufficient, a new well-improvised ignition
system was given birth and named as “Triple Spark Technology” involving the use of three spark plugs rather than one
or two.

An ignition system is a system for igniting a fuel-air mixture. Ignition systems are well known in the field of internal
combustion engines such as those used in petrol (gasoline) engines used to power the majority of motor vehicles, but
they are also used in many other applications such as in oil-fired and gas-fired boilers, rocket engines, etc. The first
ignition system to use an electric spark was probably Alessandro Volta's toy electric pistol from the 1780s. Virtually
all petrol engines today use an electric spark for ignition. Magneto Ignition Coil The simplest form of spark ignition
is that using a magnet. The engine spins a magnet inside a coil, or, in the earlier designs, a coil inside a fixed
magnet, and also operates a contact breaker, interrupting the current and causing the voltage to be increased
sufficiently to jump a small gap. The spark plugs are connected directly from the magneto output. Early magnetos
had one coil, with the contact breaker (sparking plug) inside the combustion chamber. In about 1902, Bosch
introduced a double-coil magneto, with a fixed sparking plug, and the contact breaker outside the cylinder.
Magnetos are not used in modern cars, but because they generate their own electricity they are often found on
piston-engine aircraft engines and small engines such as those found in mopeds, lawnmowers, snow blowers,
chainsaws, etc. where a battery-based electrical system is not present for any combination of necessity, weight, cost,
and reliability reasons. Switchable systems
The output of a magneto depends on the speed of the engine, and therefore starting can be problematic. Some
magnetos include an impulse system, which spins the magnet quickly at the proper moment, making easier starting
at slow cranking speeds. Some engines, such as aircraft but also the Ford Model T, used a system which relied on
non rechargeable dry cells, (similar to a large flashlight battery, and which was not maintained by a charging system
as on modern automobiles) to start the engine or for starting and running at low speed. The operator would manually
switch the ignition over to magneto operation for high speed operation. To provide high voltage for the spark from
the low voltage batteries, a 'tickler' was used, which was essentially a larger version of the once widespread electric
buzzer. With this apparatus, the direct current passes through an electromagnetic coil which pulls open a pair of
contact points, interrupting the current; the magnetic field collapses, the spring-loaded points close again, the circuit
is reestablished, and the cycle repeats rapidly. The rapidly collapsing magnetic field, however, induces a high
voltage across the coil which can only relieve itself by arcing across the contact points; while in the case of the
buzzer this is a problem as it causes the points to oxidize and/or weld together, in the case of the ignition system this
becomes the source of the high voltage to operate the spark plugs.
II. DTSI (DIGITAL TWIN SPARK IGNITION SYSTEM)
It is very interesting to know about complete combustion in automobile engineering, because in actual practice,
perfect combustion is not at all possible due to various losses in the combustion chamber as well as design of the internal combustion engine. Moreover the process of burning of the fuel is also not instantaneous. However an
alternate solution to it is by making the combustion of fuel as fast as possible. This can be done by using two spark
plugs which spark alternatively at a certain time interval so as increase the diameter of the flame & burn the fuel
instantaneously. This system is called DTSI (Digital Twin Spark Ignition system). In this system, due to twin sparks,
combustion will be complete.
This paper represents the working of digital twin spark ignition system, how twin sparks are produced at 20,000
Volts, their timings, efficiency, advantages & disadvantages, diameter of the flame, how complete combustion is
possible & how to decrease smoke & exhausts from the exhaust pipe of the bike using Twin Spark System.
