Automotive emission is becoming a critical threat to today’s human health. Many researchers are studying engine designs leading to less fuel consumption. Gearbox selection plays a key role in an engine design. In this study, Taguchi quality engineering method is employed, and optimum gear ratios in a five speed gear box is obtained. A table of various gear ratios is suggested by design o...

Climate change is a major issue all around the world. The transportation industry currently accounts for most CO2 emissions. goal of this research to develop real-world eco-driving cycle internal combustion engine motorcycles that can reduce fuel consumption and This study developed onboard measuring equipment measure speed profile motorcycle driving in real time. A total 78 riders rode test wi...

Mobile emission inventories are constructed by multiplying a pollutant emission factor by a travel activity (e.g., number of trips, vehicle miles traveled, etc.). To create emission rates, vehicles are tested on dynamometers using driving cycles, or speed-time traces. The process currently used to create the driving cycles is deterministic. However, if we examine the data and data collection te...
