Wuling Zhiguang's sluggish and dull acceleration is caused by exhaust, fuel system, electrical system, and exhaust issues. Intake system: Check if the air filter is clogged. Fuel system: Check if the fuel filter is clogged; inspect whether the engine fuel supply rubber hose is aged or cracked; disassemble the fuel injector and clean it with carburetor cleaner; disassemble the fuel supply pipe on the engine side and try starting the engine, directing the fuel pipe elsewhere to see if the fuel sprays vigorously; if the pressure is low, the fuel pump may be faulty. Electrical system: Disassemble the spark plug to check for severe blackening; inspect the high-voltage coil wiring for any damage. Exhaust system: Run the engine for a while; open the hood and observe if the exhaust pipe turns red, indicating poor exhaust flow.

Does the 48V Mild Hybrid System Need Charging?

48V mild hybrid vehicles do not require charging. The hybrid system utilizes part of the engine's power to generate electricity and store it in the battery when the vehicle does not require high power output from the engine. Additionally, the kinetic energy reduced during vehicle deceleration and braking is converted into electrical energy and stored in the battery through a process known as "regenerative braking". Below is relevant information about mild hybrid systems: 1. In traditional internal combustion engine vehicles, idling at traffic lights or in traffic jams leads to energy waste and environmental pollution. The BSG (Belt-driven Starter Generator) system intelligently shuts off the engine under such conditions, achieving both environmental protection and fuel savings. 2. During startup, the BSG motor, powered by the battery pack, can reach 3000r/min in an extremely short time with very high ignition success rates. This allows the system to bypass the traditional engine's process of accelerating from zero to idle speed, thereby achieving fuel efficiency.

What Causes Weak Acceleration in Manual Transmission Cars?

Introduction to causes of weak acceleration when starting: 1. Engine or transmission issues: This is a fault-induced weak acceleration that requires timely troubleshooting; 2. Small engine displacement with heavy load: Many modern vehicles adopt small-displacement turbocharged powertrains. When starting, the engine may not reach the turbocharging RPM, resulting in perceived weak acceleration - this is normal. Other possible causes include: 1. Throttle carbon buildup: Carbon deposits on the throttle body affect air intake volume, leading to insufficient engine power and weak acceleration. The solution is throttle cleaning. 2. Transmission clutch failure: The clutch transmits and disengages engine power. Manual transmissions and dual-clutch transmissions use friction plate clutches. Prolonged use causes severe wear and slipping, resulting in weak acceleration.

What is the P2138 fault?

If the vehicle displays the P2138 fault code, it indicates an issue with the car's throttle or accelerator pedal sensor. The specific cause should be diagnosed by professionals at a repair shop or 4S dealership. Details are as follows: 1. Throttle failure: When the throttle malfunctions, symptoms may include engine shaking, unstable idling, poor acceleration, and difficulty starting when cold. In such cases, the throttle should be thoroughly cleaned, especially removing any oil sludge buildup. If the throttle is structurally damaged, it should be replaced promptly. 2. Accelerator pedal sensor problem: When the accelerator pedal fails, symptoms may include weak acceleration, severe jerking, and unresponsiveness to throttle input. In this situation, the accelerator pedal sensor should be inspected, and high-quality fuel should be used regularly. After repairs, the fault code must be cleared promptly; otherwise, it may cause memory confusion in the vehicle's electronic system, leading to unnecessary issues later on.
