What are the reasons for Weichai's high fuel consumption?

Weichai's high fuel consumption can be attributed to the following reasons: 1. Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant factor, primarily caused by the use of inappropriate fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a substantial amount of carbon deposits in the engine. In such cases, the vehicle must be taken to a 4S shop for professional technicians to clean the carbon deposits in the engine. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the engine's fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the vehicle will emit darker exhaust gases from the tailpipe during driving. At this point, the oxygen sensor should be replaced.

I've noticed several common reasons for high fuel consumption in Weichai-powered vehicles. As a heavy truck driver with over a decade of experience, my old vehicle frequently suffers from this issue, which can be quite frustrating. The primary cause could be engine aging - especially with older vehicles, worn piston rings lead to incomplete fuel combustion, resulting in wasted fuel. Secondly, improper maintenance like neglected clogged air filters forces the engine to work harder and consume more fuel. Driving habits also matter; when I was younger, aggressive acceleration for overtaking would spike fuel consumption, but I've since learned smoother driving saves significantly. Road conditions affect it too - Weichai engines consume more fuel during uphill climbs or when overloaded, as I clearly observed during my mountain route assignments. Overall, these combined factors keep fuel consumption high, so paying attention to these details can lead to substantial savings.

When repairing Weichai engines, I often find fuel consumption issues stem from technical details. Clogged or damaged fuel injectors are the main cause; poor atomization requires extra fuel injection for compensation. Additionally, unstable fuel pump pressure or improper regulation can lead to excessive fuel supply, increasing unnecessary consumption. Not replacing the filter on time can also clog pipelines and reduce efficiency. Furthermore, ignition system issues like spark plug carbon buildup result in incomplete combustion and fuel waste. In Weichai vehicle designs, poor valve sealing causing air leakage may also lead to excessive fuel consumption. For routine maintenance, it's advised that owners regularly inspect these components. Addressing minor issues early prevents them from escalating, which is crucial for fuel consumption control and extends engine lifespan. In short, technical faults are the core of high fuel consumption, and timely maintenance can significantly improve it.

Driving a Weichai vehicle, I noticed that personal habits greatly affect fuel consumption. Always rushing to accelerate or brake suddenly forces the engine to consume more fuel to keep up with the pace. After driving smoothly, the fuel consumption becomes much more normal. Road conditions also matter, as mountainous or bumpy roads force the engine to work harder, increasing consumption. Maintaining a steady speed is the most fuel-efficient; don't follow the trend of overtaking. Simple small adjustments can save a lot of money.
