“…Consequently, enhancing engine performance has become necessary. Up to the present day, notable improvements in engines have been implemented, focusing on components like the intake manifold [1][2][3] and exhaust manifold [4][5]. Additionally, the integration of advanced technologies has been instrumental in reducing exhaust emissions and improving fuel efficiency [6][7][8][9].…”

In many countries, motorcycles have become a primary and popular mode of transportation, driven by increasing demand due to their convenience. However, as fossil fuel sources deplete, there's a pressing need to enhance engine performance, efficiency, fuel economy, and reduce emissions. Improving ignition systems is crucial in achieving these goals. This study compares the performance of the Honda Future FI 125cc engine between a laser ignition system (LIS) and a conventional ignition system (CIS) using simulation. CATIA software was utilized to design the engine's intake manifold, ANSYS Fluent software for simulating and determining the optimal swirl and tumble ratio, and Matlab/Simulink for modeling and simulating engine performance with both LIS and CIS. Detailed discussions and comparisons were made on parameters such as cylinder air mass, ignition energy, engine power and torque, specific fuel consumption (SFC), and mass fraction burned (MFB) between LIS and CIS. Overall, LIS demonstrated superior engine performance compared to CIS. This finding is significant for evaluating the advantages of LIS in motorcycles, especially in the Honda Future FI 125cc engine.

“…As far as gaseous emissions produced by an engine fueled with gasoline-ethanol blends are concerned, studies available in literature generally indicate that increasing the ethanol fraction leads to a reductions of HC, CO, CO 2 , and NO x emissions [9], [10]. In detail, HC and CO emissions tend to decrease thanks to ethanol addition due to its oxygen content [11], while its higher hydrogen-to-carbon ratio with respect to gasoline permits to reduce CO 2 emissions.…”

“…However, it is important to note that the formation of acetaldehyde (C2H4O) and formaldehyde (CH2O) may increase significantly [10]. These substances, although they are still under investigation about their effects on humans, could be associated to irritation, allergic contact dermatitis, cancer, pulmonary oedema [15] [16].…”

E85 (85 vol% ethanol and 15 vol% gasoline blend) is one of the most promising sustainable fuels for SI engines, thanks to the optimum trade-off between pollutant emissions and cost of implementation, starting from a pure gasoline baseline. From the point of view of engine performance, the most relevant differences from such a baseline are related to the heat of vaporization and to the laminar flame speed. The higher heat of vaporization helps to reduce combustion temperature, thus the risk of knocking, but it also slows down the air-mixing process; the small amount of Oxygen in the fuel molecule leads to a slightly different combustion behavior. The goal of this study is to compare commercial gasoline (E5, 5 vol% ethanol and 95 vol% gasoline blend) and E85, by means of CFD 1D (GT-Power) and 3D (AVL-FIRE) simulations, using experimentally calibrated models. The reference engine is a single-cylinder, four-stroke, PFI motorcycle unit, with a displacement of 463 cc and a maximum power > 30 kW at 9500 rpm. After the calibration, carried out on the E5 version, the fuel type is changed to E85 in the 1D model, in order to provide accurate Initial Conditions (ICs) and Boundary Conditions (BNDs) to the CFD-3D analysis. Then, a series of combustion simulations are carried out at maximum power operative point (9500 rpm – WOT), varying spark advance and equivalence ratios. Results reveal that an increase of fuel flow rate and a new calibration of spark timing are needed when the engine runs on E85 to reach performances comparable to the ones obtained with E5. Simulations also show that, moving from E5 to E85, combustion efficiency can be significantly increased, with a small reduction in engine performance. An estimation of specific emissions, provided by ECFM-3Z combustion model, show that, using E85, CO and HC emissions can be significantly reduced with a small increase of NO emissions, compared to gasoline case.

The performance every mmotorcycles is influenced by several factors as usual, including the usage of fuel typed. The study aim was to determine the effect fuels such as pertalite, pertamax, and pertamax-turbo type toward the power performance, torque and exhaust emissions produced by a 4-stroke motorbike. The try-out test with experimental methods was done by using motorcylcle of Honda CB 150 R that produced in 2016 as a sample. A sportdyno V3.3 SD325 is a dynamometer used to measure a power and torque, meanwhile eshbon HG-510 is a gas analyzer to measure an exhaust emissions. The fuel variations are pertalite, pertamax, and pertamax turbo. The research finding of this study show that 4-point results, they are: 1) In the range 4,250 to 11,000 rpm showed the maximum pertalite power on 12.53 kW at 9,414 rpm, pertamax 12.48 kW at 9,265 rpm, pertamax-turbo 12.28 kW at 9,403 rpm. 2) In the maximum torque achieved by the pertamax-turbo is 14.07 Nm at 7,237 rpm, pertalite 13.88 Nm at 7,300, and pertamax is 13.86 at 7,611 rpm. 3) In testing exhaust emissions placed on 1,500 to 7,500 rpm, pertalite fuel decreased CO from 2.92% to 0.61% and HC from 405 ppm to 225 ppm, pertamax CO from 2.79% to 0.46% and HC from 393 ppm to 170 ppm, and pertamax turbo CO from 2.44% to 0.38% and HC from 373 ppm to 158 ppm. And the last, 4) the emission test takes into account the usage of high octane fuel will show the smaller impact on environmental pollution.
