What are the reasons for high fuel consumption in foot-pedal motorcycles?
2 Answers
High fuel consumption in motorcycles may be caused by excessively high idle speed, or it may be due to low tire pressure leading to excessive friction between the tires and the ground. The fuel consumption of motorcycles is generally within the range specified in the manual. However, improper use, maintenance, or adjustments can often result in a significant increase in fuel consumption. Additional information: 1. Ignition timing too late or too early: If the ignition timing is too early, the air-fuel mixture burns prematurely, creating resistance to the upward movement of the piston, which consumes some of the effective thermal energy, leading to a decrease in engine power and an increase in fuel consumption. 2. Fuel with an excessively low octane rating: Using gasoline with too low an octane rating can easily lead to increased fuel consumption. Generally, gasoline with a higher octane rating has better combustion performance. Therefore, the correct fuel should be selected according to the fuel grade specified in the manual.
After riding motorcycles for a long time, I found that one of the common reasons for high fuel consumption is improper engine maintenance. A dirty air filter can restrict airflow, forcing the engine to burn more fuel to operate normally. Insufficient tire pressure also increases friction, leading to higher fuel consumption, so I check tire pressure weekly to ensure it's at the recommended level. Worn spark plugs or ignition system issues are another cause, as delayed or incomplete combustion wastes fuel. Additionally, engine oil that hasn't been changed for too long loses its fluidity, reducing engine efficiency. These are common issues, and regular maintenance, especially air filter replacement, can significantly reduce fuel consumption, saving both hassle and money.
