Reasons for High Fuel Consumption in Classic Focus
1 Answers
Long idling time, etc. Below are the reasons for high fuel consumption in Classic Focus: 1. Not turning off the engine during long idling: Compared to normal driving conditions, the engine ECU controls a higher fuel injection volume during idling or right after startup. If the engine is left idling for a long time without turning it off or frequently restarted, fuel consumption will inevitably increase. If parked for more than 1 minute, it is advisable to turn off the engine to wait, which is both fuel-efficient and environmentally friendly. 2. Excessive carbon buildup: Increased carbon buildup makes the intake pipe wall surface rough, affecting the intake efficiency and leading to higher fuel consumption. 3. Poor cylinder sealing: After prolonged use, the cylinder sealing of the car deteriorates. Poor sealing affects the working efficiency of the piston, reduces the conversion rate, and naturally increases fuel consumption.
