Truck Diesel Engines WP12/WP13
WP12 is jointly developed by Weichai's European R&D Centre, AVL, and Bosch and provides world-leading performance
Economy: High-pressure common rail technology reduces fuel consumption, emission, and noise. Low rated speed (1900 RPM) helps minimize friction and improve reliability, and provides comfort and lower noise.
Dynamic performance : These are powerful engines with low speed and high torque.
