DIGITAL TWIN SPARK IGNITION (DTSI)
A New Revolution of Twin Spark in I.C. Engine

Abstract
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
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.

Introduction
A conventional 4 Stroke engine has a Single Spark Plug located at one end of the combustion chamber and hence the combustion is inefficient leading to sub optimal

    Case Study Dodge Fire

    • 1189 Words

    1. There were several conceptual blocks experienced by the smokejumpers. The first conceptual block occurred when Dodge saw that the fire had crossed the gulch ahead of the crew and he redirected them to start ascending up the hill. The smokejumpers could not understand why Dodge would instruct them to go this route when it seemed much safer and more feasible to keep trekking toward the river. This is an example of compression. The smokejumpers were not seeking to find much needed information or clues to help aid them in the process of controlling the fire. The smokejumpers were to set on following orders instead of being observant, if they had been they to would have seen that the fire had crossed the gulch just as Dodge did. They were more focused on the quisitive notion of trekking through the bunch grass instead of filtering out this irrelevant information.…

    Diesel Fuel Injection

    • 908 Words
    • 4 Pages

    The injector on a diesel engine is its most complex component and has been the subject of a great deal of experimentation -- in any particular engine, it may be located in a variety of places. The injector has to be able to withstand the temperature and pressure inside the cylinder and still deliver the fuel in a fine mist. Getting the mist circulated in the cylinder so that it is evenly distributed is also a problem, so some diesel engines employ special induction valves, pre-combustion chambers or other devices to swirl the air in the combustion chamber or otherwise improve the ignition and combustion process.…

    ignition switch

    • 361 Words
    • 1 Page

    Our topic for group C is the GM ignition switches that were faulty and have caused several deaths. According to the media the car could shut off while driving and the driver could lose control of the vehicle. I think the worst part is when this happens to the car it shuts off while driving and the air bags will not deploy on impact. I feel like this topic becomes an ethical topic because apparently GM new that the switch was faulty and continued to sell the cars and install the substandard switch. The initial recall was not all cars with the faulty switch and several more lives were lost between the recall of the second group of recalls released several weeks later. The initial supply order for the parts needed to fix the faulty switch were distributed to several dealerships. This was a huge problem because the demand for the switches was much higher that the supplies distributed to the dealerships. The demand was so high for the switches in question that the supply was diminished in 2 months.…

    What Is Combustion?

    • 1132 Words
    • 5 Pages

    Combustion is the rapid burning of fossil fuels. Stored carbon in coal, oil and natural gas returns to the atmosphere when these fossil fuels are burnt and during natural combustion occurrences such as volcanic eruptions. Fossil Fuels such as coal are constructed when a living organism dies and decomposers, ie Fungi and microbes are unable to decompose it. After the organic material is untouched for millions of years, it eventually turns into fossil fuels. Petroleum, coal and natural gas Carbon is stored in fossil fuels until they are released from the ground and burnt. Fossil fuels are extracted from the ground via mining. The fossil fuels are later used in many ways to benefit humans. For example, they are used to power…
