If problems occur on this system, the combustion process cannot be done and these results the engine cannot be start. Typically motorcycle users do not use a proper tool to diagnose the problem.

Thus they are exposed to high voltage shock hazard. A tool is needs to diagnose the problem. The main purpose of this report is to design and develop a spark plug tester for motorcycle user to test the spark plug and ignition wire connectivity. Thus the risk of high voltage shock will be minimized. This report will show the process design and development of the portable spark plug tester. The development of this device is start from product architecture that descripts all function and elements of the components in this device.

The most crucial parts of this system are the spark plug. The spark plug need to supply a proper spark to the engine.

If the proper spark not being supplied to the engine, the combustion process cannot be done. The problem of ignition circuit connectivity may prevent the engine from being turned on because it cannot allow the current to spark plug. These will caused the spark plug cannot able to create the spark to start the combustion process.

The critical factor of this problem is that it must be identified at an early stage of the diagnosis before repairing. Typically, motorcycle user does not use a proper tool to test the spark plug thus they are exposing themselves to the risk of high voltage shock.

They also need to use multimeter to check the connectivity of ignition circuit. The most spark plugs dont need to be replaced; they are simply less efficient because of the carbon content spreader over the spark plug.

The electrode is present in the centre of the spark plug. In the spark plug always we need to maintain the gap between the electrode and the spark pin. While on engine running the high voltage current will be passing through the spark plug to generate the spark inside the engine to burn the air fuel mixture inside the engine cylinder.

Due to this process the carbon content spread over the spark plug. By running the vehicle with out cleaning the spark plugs causes many damages to the vehicle.

For eg, mileage drop, produce sound, damage the cylinder due to uneven sequencing of spark produced inside the cylinder. After removing the carbon content in the spark plug we can reuse the spark plug. It will give more efficiency as compare to old one. Automobile workshops the spark plug cleaning and exact testing consumes more time by using the manual testing, so make simplification setup in testing and cleaning, we are going to design and fabricate a single setup to save the time.

Figure 1: The typical way of a motorcycle user to check the spark of spark plug. A special tool is needed to properly diagnosing the problem.

Hence, there is a need to design and develop a spark plug tester for a motorcycle user to test the wire and spark plug conductivity. OBJECTIVE The objective of this project is to design and develop a portable spark plug tester for the motorcycle user that allow the motorcycle user to test the connectivity of ignition wire and spark plug without exposing themselves to the risk of high voltage shock. Come out with a design of a portable spark plug tester with dual functions 2. This literature review covers the previous study and information that are related to this project.

The information will be used as value added or reference for this project. The information can be found from book, internet, journal, paper work and so on. In early motorcycle internal combustion engine design development there are three elements that are important.

The elements of engine design are ignition, carburetion and lubrication. To achieve the rotational force it is necessary to make the engine crank by using force from explosion of a substance. The substance that is most commonly used is a mixture of fuel and air and ignition source that will cause the explosion. In early development of internal combustion engine, both mixing of fuel- air mixture and igniting are quite tricky and dangerous. Steven E. Alford, Suzanne Ferriss , Early design of ignition system undergoes three type of system that is flame, hot tube and magneto ignition.

Between all the system, the magneto system is commonly use because it has a controlled spark that ignites the mixture. These systems use an external power like battery, rather than using an internal flywheel magnet to create a spark to ignite the mixture.

These technologies lasted until s because introduced of more advanced ignition system. Alford, Suzanne Ferriss, This ignition system was used for a long time as it facilitate and have a great reliability but being mechanical, it has some inherent failings. Later it is enhanced to electronic ignition system.

Adam Wade, The main purpose of an ignition System is a spark that will ignite the air and fuel mixture in the combustion chamber. For each cylinder in the engine, the ignition system has three main functions that are to generate enough electrical spark to ignite the mixture in combustion chamber, must maintain the spark to allow complete combustion, and it has to deliver the spark on time to each cylinder.

Edward Abdo , Figure 3: Simplified drawing of the basic components of an ignition system EdwardAbdo , Figure 3 shows the basic component of ignition system and the connections and interactions between components to allow the system to be functional. The functions of all components are different. Power source uses the magnetism principle to produce a voltage and ignition switch allows the power source to provide electrical power to the ignition system. In ignition coil the current will pass through the transformer.

From 12 volt input, the ignition coil will produce 20, to 60, volts or even more and the high voltage is connected to the spark plug. A spark plug has a metal threaded shell, electrically isolated from a central electrode by a porcelain insulator.

The central electrode, which may contain a resistor, is connected by a heavily insulated wire to the output terminal of an ignition coil or magneto. The spark plug's metal shell is screwed into the engine's cylinder head and thus electrically grounded.

The central electrode protrudes through the porcelain insulator into the combustion chamber, forming one or more spark gaps between the inner end of the central electrode and usually one or more protuberances or structures attached to the inner end of the threaded shell and designated the side, earth, or ground electrode. Operation The plug is connected to the high voltage generated by an ignition coil or magneto. As current flows from the coil, a voltage develops between the central and side electrodes.

Initially no current can flow because the fuel and air in the gap is an insulator, but as the voltage rises further it begins to change the structure of the gases between the electrodes.

Once the voltage exceeds the dielectric strength of the gases, the gases become ionized. The ionized gas becomes a conductor and allows current to flow across the gap. Spark plugs usually require voltage of 12,, volts or more to "fire" properly, although it can go up to 45, volts.

They supply higher current during the discharge process, resulting in a hotter and longer-duration spark. As the current of electrons surges across the gap, it raises the temperature of the spark channel to 60, K. The intense heat in the spark channel causes the ionized gas to expand very quickly, like a small explosion. This is the "click" heard when observing a spark, similar to lightning and thunder. The heat and pressure force the gases to react with each other, and at the end of the spark event there should be a small ball of fire in the spark gap as the gases burn on their own.

The size of this fireball, or kernel, depends on the exact composition of the mixture between the electrodes and the level of combustion chamber turbulence at the time of the spark.

A small kernel will make the engine run as though the ignition timing was retarded, and a large one as though the timing was advanced. Spark plug construction A spark plug is composed of a shell, insulator and the central conductor. Common thread nut sizes in Europe are 10 mm 16 mm , 14 mm 21 mm; sometimes, 16 mm , and 18 mm 24 mm, sometimes, 21 mm. In the United States, common thread nut sizes are 10mm 16mm , 12mm 14mm, 16mm or The top of the spark plug contains a terminal to connect to the ignition system.

The exact terminal construction varies depending on the use of the spark plug. Most passenger car spark plug wires snap onto the terminal of the plug, but some wires have eyelet connectors which are fastened onto the plug under a nut.

Plugs which are used for these applications often have the end of the terminal serve a double purpose as the nut on a thin threaded shaft so that they can be used for either type of connection. The main part of the insulator is typically made from sintered alumina, a very hard ceramic material with high dielectric strength, printed with the manufacturer's name and identifying marks, then glazed to improve resistance to surface spark tracking.

This extended portion, particularly in engines with deeply recessed plugs, helps extend the terminal above the cylinder head so as to make it more readily accessible. By lengthening the surface between the high voltage terminal and the grounded metal case of the spark plug, the physical shape of the ribs functions to improve the electrical insulation and prevent electrical energy from leaking along the insulator surface from the terminal to the metal case.

The disrupted and longer path makes the electricity encounter more resistance along the surface of the spark plug even in the presence of dirt and moisture. Some spark plugs are manufactured without ribs; improvements in the dielectric strength of the insulator make them less important.

On modern post s spark plugs, the tip of the insulator protruding into the combustion chamber is the same sintered aluminium oxide alumina ceramic as the upper portion, merely unglazed. It is designed to withstand C 1, F and 60 kV. The dimensions of the insulator and the metal conductor core determine the heat range of the plug.

Short insulators are usually "cooler" plugs, while "hotter" plugs are made with a lengthened path to the metal body, though this also depends on the thermally conductive metal core. Older spark plugs, particularly in aircraft, used an insulator made of stacked layers of mica, compressed by tension in the centre electrode.

With the development of leaded petrol in the s, lead deposits on the mica became a problem and reduced the interval between needing to clean the spark plug. Sintered alumina was developed by Siemens in Germany to counteract this. It also allows a simple single piece construction at low cost but high mechanical reliability. Because the spark plug also seals the combustion chamber or the engine when installed, seals are required to ensure there is no leakage from the combustion chamber.

The external seal is usually a crush washer, but some manufacturers use the cheaper method of a taper interface and simple compression to attempt sealing.

Spark plug threads are cold rolled to prevent thermal cycle fatigue. It's important to install spark plugs with the correct "reach," or thread length. Spark plugs can vary in reach from 0. Central electrode.
