Core Function

Utilizing electrical energy from the battery, it drives the engine flywheel to rotate through a combination of a DC motor + reduction gearing + electromagnetic switch. This enables the engine to complete the starting cycle of “intake - compression - fuel injection - ignition (compression ignition for diesel engines).” Once the engine runs independently, the power connection automatically disengages.

Compatible Models and Engines

Compatible Engines: Weichai WP10/WP12, Sinotruk MC11/MC13, and other heavy-duty diesel engines

Compatible Models: Sinotruk Howo, Sandaika, Dongfeng Tianlong, FAW J6, and other heavy-duty trucks

(Model QDJ2811)

Product Features

Structure Type: Belongs to the reduction-type starter (incorporating an internal planetary gear reduction mechanism). Compared to traditional direct-drive starters, it reduces motor power requirements, enhances torque output, and accommodates the starting load of large-displacement engines.

Core Components:

DC Motor: Converts electrical energy into mechanical energy to provide starting power;

Electromagnetic Switch: Controls motor energization and engages the drive gear with the flywheel;

Reduction Mechanism: Amplifies motor torque to ensure sufficient power output during starting.

Performance Parameters: Typically operates at 24V voltage with power exceeding 5.5kW, delivering torque up to 100N・m or higher to meet heavy-duty engine starting demands.

Maintenance Key Points: Regularly inspect battery voltage (preventing discharge-induced starter overload); If “no response during start-up” occurs, troubleshoot electromagnetic switch or motor coil faults; If “gear binding” occurs, check meshing clearance between drive gear and flywheel.
