Effect of using a high performance-low pollution muffler (hplpm) with catalytic converter on fuel consumtion and performance of 110cc

Introduction

Effect of using a high performance-low pollution muffler (hplpm) with catalytic converter on fuel consumtion and performance of 110cc. Evaluate HPLPM with catalytic converter on 110cc motorcycles. Compare standard exhaust vs. modified HPLPM for fuel consumption, power, and torque performance.

Abstract

The increse in the number of motorcycles to fulfil mobility is domianted by matic type. Over time the vehicle will experience a derease in performance and appearance, triggering modification. the purpose of this study was to determine the difference in motorcycle performance with the use of standard exhaust, HPLPM 2 + catalytic converter and HPLPM mod + catalytic converter. This reaserch was conducted with a quantitative research meode with an experiemental approach, performance testing test data at engine speed of 3000-9000 rpm. Engine temperature 80 degree with pertamax fuel ocatane 92. In this study, HPLPM mod + catalytic converter produces 12,23 N.m of torque at 4500 rpm, the highest power produced by HPLPM 2 + catalytic converter 8,27 Hp at 5500 rpm. exhaust HPLPM mod + catalytic converter is able to maintain power at high rpm 7,70 Hp at 8250 rpm.

Review

This study investigates the effect of high-performance, low-pollution mufflers (HPLPM) with catalytic converters on the performance of 110cc "matic" type motorcycles. The research addresses a relevant topic within automotive engineering, specifically the popular practice of motorcycle modification and its impact on vehicle dynamics. The stated objective to compare the performance of standard, HPLPM 2, and HPLPM mod exhaust configurations with catalytic converters is clear, aligning with the practical interests of both vehicle owners and potential manufacturers. Methodologically, the abstract outlines a quantitative, experimental approach, which is appropriate for evaluating performance differences. The experimental conditions, including the engine speed range (3000-9000 rpm), engine temperature (80 degrees), and fuel type (Pertamax, octane 92), provide a good foundation for reproducibility. The key findings are clearly presented, indicating that the HPLPM mod + catalytic converter produced the highest torque (12.23 N.m at 4500 rpm), while the HPLPM 2 + catalytic converter achieved the highest peak power (8.27 Hp at 5500 rpm). The abstract also highlights the HPLPM mod + catalytic converter's ability to maintain power at high RPMs, offering valuable comparative data. Despite the clear performance data, there are significant areas where the abstract, and implicitly the study, could be strengthened. Most notably, the title explicitly mentions "fuel consumption and performance" and "low pollution," but the abstract only discusses performance metrics (torque and power). There is a critical absence of any data or discussion regarding fuel consumption or pollution reduction, which are fundamental components implied by the HPLPM acronym and the study's stated scope. Furthermore, the abstract lacks detailed methodological specifics such as the type of dynamometer used and a clear explanation of the design differences between "HPLPM 2" and "HPLPM mod." Inclusion of statistical analysis to confirm the significance of the observed performance differences would also greatly enhance the robustness of the conclusions. For publication, the full paper must address these discrepancies, providing the promised data on fuel consumption and pollution, and elaborating on the experimental design.
