How to Solve High Fuel Consumption in FAW Trucks?
3 Answers
Regular maintenance and inspections are essential during daily use. It's best to address any issues immediately upon discovery. Reduce vehicle weight by regularly cleaning the trunk and avoiding unnecessary items in the car. Correct improper driving habits. For automatic transmissions, ease off the accelerator when RPM reaches 2000-3500. Maintain steady acceleration. Sudden throttle closures may confuse the engine control unit about whether the driver intends to decelerate or accelerate. Avoid coasting in neutral gear as it consumes idle fuel, equivalent to the fuel consumption at 60 km/h.
High fuel consumption can indeed be frustrating, and I believe it's mainly related to driving habits. Having driven for many years, I've noticed that FAW trucks tend to consume more fuel due to sudden acceleration and hard braking. Maintaining a steady speed between 70 to 80 km/h is most fuel-efficient. Reduce idling time, and when starting the engine, don't warm it up for too long—just a minute or two is enough. Overloading is a common cause, so make sure not to exceed the cargo limit. Regularly check tire pressure and inflate according to the manual's recommended values, as underinflation increases friction. Routine maintenance, including oil changes and air filter replacements, ensures smooth engine operation. Accelerate gently when unloaded, and use cruise control on highways for better efficiency. Environmental temperature also plays a role; in summer, the added load from air conditioning naturally increases fuel consumption. Adopting these good habits can gradually reduce fuel consumption, saving money and extending the vehicle's lifespan.
From a car repair perspective, high fuel consumption is mostly caused by neglecting minor issues. I recommend first checking if the air filter is clogged or too dirty - replacing it with a new one to ensure smooth airflow can save significant fuel. Engine oil loses lubricity when aged, so change it on schedule with the specified grade. Inspect tire wear conditions and perform wheel alignment/balancing if needed. Faulty spark plugs may cause poor ignition and weak sparks, increasing fuel consumption. Cleaning the fuel system is crucial - use qualified additives to clean the injectors. Ensure the brake system isn't dragging, as stuck brakes create extra resistance. Also check sensors - a faulty oxygen sensor affects combustion efficiency. Generator or voltage regulator failures can cause unstable power supply too. Get comprehensive inspections at repair shops regularly, especially scanning the onboard computer for trouble codes to target problems precisely without spending much. Addressing these minor issues promptly can effectively control fuel consumption.
