The Difference

<p class="Judul">The basic concept of a combustion motor is to convert chemical energy into heat energy and then convert it to mechanical energy. Heat energy is produced from the combustion process between a mixture of fuel and air with a pressure difference triggered by  spark (flame). The objective is to determine the difference in power, torque, and average effective pressure by adding the number of spark plugs and using the standard type of spark plug and iridium on a single-cylinder engine. The engine performance testing method uses P-max to get power, while the analysis uses experimental design, the data processing method uses DOE-factorial and the Minitab application 18. Power test for a standard spark plug resulted in 7.93 HP, 0.89 kgm torque and 1207.66 kPa average effective pressure. For iridium spark plug the test produced 9.02 HP, it is  0.91 kg.m for torque and average effective pressure is 1226.32 Kpa. For two standard spark plugs, the power was 9.38 HP, torque was 0.93 kg.m, and the average effective pressure was 1269.96 kPa. Whereas the two iridium spark plugs produced 9.59 HP, 0.91 kg.m torque, and  1277.78  kPa average effective pressure.</p>

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.

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.

Laser ignition of natural gas engines has shown potential to improve many facets of engine performance including brake thermal efficiency, exhaust emissions, and durability as compared with traditional spark ignition. We present proof of concept of a novel fiber optic delivery approach using solid core multimode step index silica fibers with large cladding diameters (400 m core, 720 m cladding). The fibers were able to deliver high beam quality 25 nanosecond pulses of 1064 nm light with 7–10 mJ energy; sufficient to consistently ignite the engine at various air-fuel ratios and loads. Comparative tests between the laser spark plug and a traditional J-gap spark plug were performed on a single cylinder Waukesha Cooperative Fuel Research (CFR) engine running on bottled methane. Performance was measured in terms of the Coefficient of Variation (COV) of Net Mean Effective Pressure (NMEP), fuel specific efficiency, and emissions of oxides of nitrogen (NOx), carbon monoxide (CO), and total hydrocarbons (THC). Tests were run at three different NMEPs of 6, 8, and 12 bar at various air-fuel ratios. Results indicate successful operation of the fiber and improved engine performance at high NMEP and lean conditions.

Spark plug based engine combustion diagnostics have the advantage of simplicity and easy access. Over the years there has been considerable interest in developing and applying spark plug ionization probes to monitor the in-cylinder combustion process. In this paper, alternative approaches are presented using the spark plug as the primary sensor. These methods are based on the analysis of the spark voltage and a secondary high-voltage discharge. A series of experiments have been conducted to evaluate their potential in the measurement of combustion quality and the detection of misfire. It is found that the spark voltage decay time is related to the initial flame kernel development and may be used to detect misfire and deteriorating combustion quality in the initial flame development. The results also show that the analysis of secondary voltage decay time could be an effective means of monitoring the combustion quality and detecting misfire during the main combustion period.

The incompatibility between the width of the plug and the combustion engine fuel used causes a backfire and a knock. The spark plug gap had therefore been investigated in order to improve the engine's performance by controlling the combustion process. The main objective of this study is to analyze the effect of side gapping spark plug engine performance and emission. The selected type of spark plug being used for this study is cooper spark plug. This study has examined the parameters of side gapping spark plug gap (0.7 mm, 0.8 mm, 1.0 mm and 1.2 mm) and of revolution per minutes RPM (1000 rpm, 1500 rpm, 2000 rpm, 2000 rpm, 2500 rpm, 3000rpm, 3500 rpm, 4000 rpm, 4500 rpm and 5000 rpm) also the emission effect in term of carbon monoxide (CO), hydrocarbon (HC) and oxygen (O2 ).

The Right

Ideally, the combustion system system in the combustion chamber, this is an alarm in order to get the right combustion results and of course will make the motorcycle power with the right fuel consumption too. There are at least 3 (three) important factors that must be met by the combustion system in the combustion motorbike, especially for gasoline-type automatic motorbikes. These three factors include the existence of an ideal fuel and air mixture (good air-fuel mixture), the right timing of business performance in producing spark plug spark quality (good spark) and good combustion chamber (good compression). An air-fuel mixture that can produce a homogeneous mixing of fuel and air. The acquisition of perfect combustion is directly proportional to the quality of a good type of spark plug cable. The ability of the type of spark plug cable must be able to support high electric current processes to produce the ideal spark. In this study, the type of business cable used is the brand that is in the market, namely proteck, extreme, hitachi and standard cable types. Performed variation testing 4 (four) types of spark plug cables. The test results show the best engine performance of a gasoline-fueled automatic motorbike using extreme spark plug cables, with a torque of 5,669 Nm at 7854 rpm and a power of 6,252 hp at 7854 rpm
