Weichai 4102 Diesel Engine for Bunker Cement Trailer

The Weichai WP4.1 series 4102 diesel engine is the proven auxiliary power unit for bunker cement trailer pneumatic discharge systems. This 4-cylinder inline diesel engine drives the air compressor that fluidizes and unloads cement powder from the trailer body — a critical function for ready-mix concrete operations and bulk cement logistics.

With 130HP output and a compact footprint, the 4102 engine fits neatly into the small engine compartment of most 3-axle and 4-axle cement trailer designs. The reliable mechanical fuel injection system and simple cooling circuit ensure minimal maintenance requirements and maximum uptime in demanding construction site conditions.

At HOWO Special Truck Export Co., Ltd, we supply Weichai 4102 engines with mounting brackets, belt drives, and all adapters for direct connection to standard cement trailer air compressors. Contact us for competitive pricing and availability.
