What are the reasons for insufficient power in the JAC Shuailing?

[Gonçalves]

JAC Shuailing's insufficient power may be due to using a decoder to access the system and reading fault information, including issues with the particulate filter, timing signal, and rail pressure deviation in the fuel system. Below is an introduction to the JAC Shuailing: 1. Introduction: The JAC Shuailing is the high-end brand series of JAC light trucks. The model features three series—wide, medium, and narrow—covering single-row to half-row products, fully expanding the choices for different consumers. The launch of the Shuailing III has formed a new Shuailing family, including the Shuailing and Shuailing II, bringing richer options for high-end light truck users. 2. Power: Maximum output power: 88KW, torque: 280N·m, horsepower: 120HP, maximum torque speed: 2000-2200. 3. Features: The new-generation Shuailing is JAC's high-end light truck model, developed with a focus on world-class light trucks, targeting urban logistics and enterprise clients in economically developed regions. It features a new cab, new engine, and new chassis, inheriting consistent quality.

I've driven quite a few JAC Shuailing models, and insufficient power is a common issue, likely due to multiple underlying reasons. Severe engine carbon buildup can clog the intake and exhaust systems, leading to incomplete fuel combustion; problems in the fuel system, such as insufficient fuel pump pressure or clogged fuel lines, can also make the car sluggish during acceleration. If the turbocharger is aging or stuck with debris, turbo lag may occur; clutch and transmission slippage is also common, especially noticeable when climbing hills. Sensor failures, like a faulty mass airflow sensor, can cause the ECU to misread data and affect performance. When you notice a drop in power, don't delay—it's advisable to visit a 4S shop for a comprehensive inspection. Regular carbon cleaning and air filter replacement can effectively prevent this issue and protect engine longevity.

I've been driving a JAC Shuailing for many years, and the lack of power is really annoying. I've encountered several different causes. Once, the fuel filter was too dirty, cutting off the fuel supply; another time, the exhaust system was blocked, causing exhaust gases to flow back. In summer, the power also weakens when the air conditioning is on due to the increased load. Clutch slippage is particularly noticeable on uphill sections, making gear shifting less smooth. Fuel quality is also crucial—I've used cheap fuel before, and carbon buildup was rapid. I recommend checking the engine oil and fuel lines weekly, replacing spark plugs promptly, and warming up the engine before driving. If you feel the car struggling to move, pull over and check—never force it to avoid causing more serious damage.

During car modification, encountering insufficient power in the Shuailing may be due to excessive engine carbon deposits; fuel injection issues causing incorrect air-fuel mixture; clogged air filter restricting airflow; aged spark plugs causing delayed ignition; or faulty sensors providing inaccurate signals. I personally tried cleaning carbon deposits and replacing the air filter, which immediately restored much of the power. Neglecting long-term maintenance can easily lead to problems—avoid using low-quality fuel and regularly drive at high speeds to clean carbon deposits. Addressing these issues early saves trouble and money; otherwise, minor problems can escalate into major repairs.
