Main Components

The Ignition on a motorcycle is an electrical system that produces sparks in the combustion chamber. If there is a mass of ferromagnetic material moving closer to the sensor, then the pulser will generate an electric current. Greater the electric current it generates. With the working principle of such a pulser, it can be used as a rotation sensor and sent to the ignition coil to produce a higher voltage which will produce sparks at the end of the spark plug electrode. The perfection of the system affects the motor work system. A good CDI condition will make it easier to increase the RPM (Rotations Per Minute) and when the spark plugs are in good condition, the motorbike's performance is getting optimal. There can be a useful tool for analyzing the damage to the CDI and the spark on the spark plug by integrating the electronic system in the motor ignition system. An electronic circuit that connects the motorcycle's ignition system through the output of the pulser circuit signal, which triggers the CDI input instead of the pulse magnet. Because the CDI and motor spark plugs are one of the main components that play an important role in the performance of the combustion motor. So that the electrical system can work without using mechanics and can be used as a tool to be able to analyze CDI damage and motor spark plug performance because CDI and spark plugs are some of the main components that play an important role in combustion motor performance. The result is that the tool can test CDI and motor spark plugs efficiently after which it can conclude the damage and can distinguish the characteristics of the CDI and the motor plugs.

Independent Variable

In automotive, many various modifications are made to improve engine performance. One that is done is to maximize the combustion that occurs in the combustion chamber. By maximizing the ignition system in the combustion process, it is expected to enlarge sparks from spark plugs. One of the components affecting the combustion process is Magnet, serves to generate electricity that will become a high voltage electric current and allow the occurrence of spark jumps on the spark plug. In this study, the independent variable is the modified tregger magnet which is reversed 0.50, to 9.50 and 90. in general there is no significant difference. Fcount value for result on magnetic trigger type = 3.00 <F (0.05; 2.24) = 3.40 (rejected H0) means reversing the 90 and 9.50 magnetic triggers does not significantly influence. In addition, Fcount for 6000, 7000, 8000 rpm engine yield = 1.00 <F (0.05; 2.24) = 3.40 (Rejected H0) means the engine's rotation rate has no significant effect. So there is no effect of fuel consumption on the modified magnetic trigger, nor at rpm 6000, rpm 7000 and rpm 8000.

Directed Energy

Abstract The natural gas industry has seen a considerable increase in production recently as the world seeks out new sources of economical, reliable, and more environmentally friendly energy. Moving this natural gas requires a complex network of pipelines and compressors, including reciprocating engines, to keep the gas moving. Many of these engines were designed more than 40 years ago and must be retrofit with modern technologies to improve their performance while simultaneously reducing the harmful emissions that they produce. In this study a directed energy ignition system is tested on a two-stroke, single cylinder, natural gas-fired engine. Stability and emissions will be observed throughout a range of spark waveforms for a single speed and load that enables the most fuel-lean operation of the engine. Improving the combustion process of the legacy pipeline engines is a substantial area of opportunity for reducing emissions output. One means of doing so is by improving an engines ability to operate at leaner conditions. To accomplish this, an ignition system needs to be able to send more energy to the spark plug in a controlled manner than a tradition capacitive-discharge ignition system. Controlling the energy is accomplished by optimizing the structure of the waveform or “profile” for each engine design. With this particular directed energy ignition system, spark profiles are able to be configured by changing the duration and amount of current sent to the spark plug. This study investigates a single operating speed and load for 9 different spark energy configurations. Engine operation at these test conditions will allow for emissions and engine performance data, using directed energy, to be analyzed in contrast to capacitive-discharge ignition.

The 4 stroke (4 cylinder) gasoline engine ignition system simulation based on the Arduino Uno microcontroller was designed as one of the modeling of conventional ignition system modification into an electronic ignition system based on the Arduino Uno microcontroller. Conventional ignition systems are modified by removing distributor components and replaced with microcontrollers as ignition system controllers. Spark plug and coil cables are replaced with Igniton coil that uses Igniter. Arduino Uno microcontroller is used as a controller that receives signals from the optocoupler sensor and activates the module relay so that the electric current enters the Ignition Trigger, the voltage needed by Igniton Trigger is 2 V by using a step down transformer to reduce the voltage. So that the Ignition Coil is active and produces a high voltage so that it can produce sparks on each spark plug. This Arduino Uno microcontroller processes data received from an optocoupler sensor

Lean Limit

An ignition system that is based on the alternating (AC) rather than the traditional direct (DC) current in the spark plug discharge has been developed at the Caterpillar Technical Center. This system can generate a long duration discharge with controllable power. It is believed that such an ignition system can provide both a leaner operating limit and a longer spark plug life than a traditional DC system due to the long discharge duration and the low discharge power. The AC ignition system has successfully been tested on a Caterpillar single cylinder G3500 natural gas engine to determine the effects on the engine performance, combustion characteristics and emissions. The test results indicate that while the AC ignition system has only a small impact on engine performance (with respect to a traditional DC system), it does extend the lean limit with lower NOx emissions. Evidences also show the potential of reduce spark plug electrode erosions from the low breakdown and sustaining discharge powers from the AC ignition system. This paper summarizes the prototype design and engine demonstration results of the AC ignition system.

Valve Overlap

Engines operating in low temperature combustion during positive valve overlap operation offer significant benefits of high fuel economy over the low temperature combustion during negative valve overlap operation. Significant efficiency improvement was achieved by the increased gamma and lower pumping loss. However, NOx emissions were increased due to reliance on the flame-induced combustion. In this study, the corona ignition system was evaluated to reduce NOx emissions during positive valve overlap operation while maintaining the benefit of efficiency gain. The tests were performed in a 2.2-L multi-cylinder engine. The results show that the ignition delay is always shorter with the corona ignition system than with the spark plug. The corona ignition system is able to support stable combustion (coefficient of variation of indicated mean effective pressure <3%) in a lower load during positive valve overlap operation than the spark plug, which gives us additional efficiency benefit. Since the corona ignition system promotes simultaneous ignition of the mixture at multiple locations in the combustion chamber as opposed to ignition being limited to the spark gap channel, the dependence of the flame burn for stable combustion during positive valve overlap operation minimizes, which leads to lower NOx emissions over the spark plug.

Beam Delivery

Using a laser, as opposed to a conventional (electrical) spark plug, to create a combustion initiating spark is potentially advantageous for several reasons: flexibility in choosing and optimizing the spark location, in particular to move the spark away from solid heat sinks; production of a more robust spark containing more energy; and obviation of electrode erosion problems. These advantages may lead to an extension of the lean limit, an increase in engine thermal efficiency, and the concomitant benefits of reduced pollutant emissions. This paper presents the design of a laser ignition system appropriate for a large bore natural gas engine. Design considerations include: optimization of spark location, design of beam delivery system and optical plug, and mitigation of vibration and thermal effects. Engine test results will be presented in the second paper of this two-paper series.
