What are the reasons for increasing fuel consumption in cars?
1 Answers
Increasing fuel consumption in cars is caused by factors such as prolonged lack of maintenance, overdue spark plug replacement, and excessive carbon buildup in the vehicle. Below is a detailed analysis of these issues: Prolonged lack of maintenance: If a vehicle has not been maintained for a long time, dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts. More energy is required to overcome this resistance, leading to higher fuel consumption. Overdue spark plug replacement: When spark plugs reach the end of their lifespan but continue to be used, insufficient ignition energy can cause delayed ignition, missing the optimal ignition timing. For example, gasoline should ideally ignite when the piston is near the top dead center. However, due to insufficient ignition energy, ignition may be delayed until the piston starts moving downward, resulting in partial power loss and energy not being utilized effectively. This also leads to incomplete combustion, further increasing fuel consumption. Excessive carbon buildup in the vehicle: Carbon deposits commonly accumulate in areas such as the throttle body, fuel injectors, intake manifold, and piston tops. Excessive carbon buildup in any of these areas can cause incomplete combustion, thereby increasing fuel consumption.
