“…In addition, CO2 emissions before and after ground strap installation were 7.80% and 4.99 %vol, respectively. Astanei et al [21] reported much lower HC emission when higher quality spark plug was used. Significant decrease of HC and CO emissions in this work was then predicted due to better fuel combustion.…”

This study is to determine fuel consumption and exhaust emissions due to addition of a ground strap to the spark plug coil cable using silver wire material. The silver wire was 0.8 mmdiameter and installed with number of turns of 255. This research was conducted since spark plug disturbance, due to electromagnetic field, decreases engine performance. This electromagnetic field occurs during electric current flows from battery to spark plug. This study applied experimental method with 10 repetitions of data collection. The results showed that the lowest specific fuel consumption reduction by 19.6% occured at 5000 rpm and the highest one by 29% occured at 8000 rpm when groundstrap was installed. Meanwhile, HC, CO and CO2 exhaust emissions decreased by 80.3%, 82.3% and 36.7%, repectively, after installation of groundstrap.

“…Several other indicators on the spark plug also affect the combustion process at SIE, such as the number of the Ground Electrode (ground electrode) and electrodes and spark plug roughness [7,[20][21][22][23]. This study will discuss the effect of multiple-ground electrode on the SIE combustion process.…”

“…The motorcycle is classified as a spark ignition engine (SIE), where the combustion process occurs due to an ignition generated by the spark plug. The spark ignition is commonly used and has higher deposit energy than laser ignition [7]. The spark plugs function to burn the fuel and air mixture in the internal combustion engine that enters the combustion chamber.…”

Motorcycle performance is influenced by many factors, including combustion chamber dimension, fuel characteristic, type of spark plug, spray flame, ignition timing, and the combustion chamber's cooling system to avoid incomplete combustion and knocking processes. The spark plug is an essential component of SIE. Several studies, such as spark plug gap, material type, multiple-ground Electrode, roughness, etc., have been conducted to examine the effect of spark plug modifications on the combustion process. Some previous research investigates the impact of a multiple-ground electrode spark plug in biofuel combustion. However, a study about the effect of multiple-ground electrode spark plugs on the gasoline combustion process has not been conducted. This research was conducted to determine the impact of multiple-ground electrode on Supra 125 cc performance. The data displayed in this study are power, torque, BHP, and BMEP in single, double, and triple ground electrode. The results showed that the double ground electrode spark plug produced better performance than other variations.

“…However, due to the low energy content per unit mass of the mixture in the mildly homogeneous lean burn state, the flame propagation speed becomes slower and the cyclic variation becomes more intense. Multipoint ignition may be a potential technology to improve this phenomenon. − Long-term practice has shown that double-spark plug ignition can significantly shorten the combustion duration, reduce cyclic variation, and expand the combustion limit. − Migita et al used twin-spark plugs located in a diagonal position and controlled the ignition timing in sequence to achieve rapid combustion. Forte et al found that at a part load condition, a sensible reduction of cycle-by-cycle variability of indicated mean effective pressure was achieved by twin-spark, and at a full load condition, the twin-spark showed an increase of power.…”

Experimental Investigation about the Effect of Double-Spark Plug Ignition on Combustion Characteristics for Motorcycle Gasoline Engines with a Mild Lean Mixture

et al. 2022

To investigate the effect of double-spark plug ignition (DSI) on the mild lean combustion characteristics of motorcycle gasoline engines, three combustion modes were set up on a gasoline engine for testing, namely, the single-spark plug ignition (SSI) stoichiometric combustion mode (λ = 1, λ represents the excess air coefficient), the DSI stoichiometric combustion mode (λ = 1), and the DSI mild lean combustion mode (λ = 1.1). The results show that the double-spark plug ignition as that in the DSI mild lean combustion mode and DSI stoichiometric combustion mode is more prominent in accelerating the combustion process, reducing the cyclic variation, and improving the lean burn stability. It is verified that the overall effect of double-spark plug ignition on accelerating mildly homogeneous lean combustion is mainly reflected during the early period of rapid burning, which improves the stability of mildly homogeneous lean combustion and extends the lean burn limit. Further, the bench test shows that at a moderate load, the DSI mild lean combustion mode can result in lower brake-specific fuel consumption (BSFC) compared to that of the DSI stoichiometric combustion mode. When using the DSI mild lean combustion mode, the fuel economy can be improved by about 3−6% compared to that when using the SSI stoichiometric combustion mode. And the emission reduction can also be clearly observed when using a three-way catalyst containing rare-earth materials. However, at a low load, limited by combustion stability, for the DSI mild lean combustion mode, λ should not exceed 1.05.
