Weichai's Diverse Powertrains Shine at 2026 International Internal Combustion E
November 13,2026
From November 11 to 13, the 2026 International Internal Combustion Engine and Power Equipment Expo was held in Nanjing. Under the theme "Diverse Power, Driving the Globe," Weichai appeared with products across multiple technology routes, comprehensively demonstrating its low-carbon and zero-carbon power solutions — from traditional engine energy-saving upgrades to hybrid and solid-oxide fuel-cell systems — driving the global power industry's green, low-carbon transition through a full-industry-chain layout.
Traditional High-Efficiency Engines Lead New Energy-Saving Trend
Traditional internal combustion engines are Weichai's stronghold and the technological foundation on which it stands in the global market. Many products on display represent Weichai's cutting-edge achievements in engines. Among them, the Weichai WP14DI dual-fuel engine and the WP15NG4.0 Pro gas engine won the "China Heart" 2026 Top 10 Commercial-Vehicle Powertrain honors.
WP14DI Dual-Fuel Engine
Adopting high-pressure in-cylinder direct gas injection with micro-pilot diesel ignition, it delivers outstanding fuel savings; the first batch of mass-produced units achieves thermal efficiency of over 48%; with no EGR system and low thermal load, it adapts to a wide range of gases and offers a B10 life of up to 2 million kilometers, ideally suited to high-frequency long-haul transport.
WP15NG4.0 Pro Gas Engine
A representative of trunk-logistics transport, with maximum power of 630 Ps and quick power response, excellent gas economy, and reliable durability. Significantly lower exhaust temperature and reduced thermal load effectively improve attendance efficiency for long-haul trunk transport.
WP14H/T-2.0 High-Thermal-Efficiency Engine
Adopting intelligent control combined with a high-thermal-efficiency combustion system for lower fuel consumption, its modular design makes after-sales maintenance more convenient — a benchmark for efficient traction-engine power.
High-Horsepower Tractor Hybrid Assembly: Innovation Leads High-End Breakthrough
The all-new 220–260 hp tractor hybrid assembly adopts a classic power-split continuously variable architecture — mature, reliable, and more efficient. Vehicle speed and engine speed are decoupled, so the engine always runs in its optimal economy zone, saving fuel; with multiple automatic operation modes, it meets full-condition power demands for plowing, rotary tillage, and seeding.
WGFH2000 Land-Based Generator Set: A High-Reliability Power Foundation
The WGFH2000 land-based generator set adopts an electronically controlled high-pressure common-rail system for fast startup; its familyized design raises parts commonality and helps cut operation and maintenance costs — suited to high-reliability power scenarios such as data centers, standby power, and power stations.
Solid-Oxide Fuel Cells, Methanol Power: Diverse Powertrains Cover Multiple Scenarios
In addition, Weichai displayed innovations for construction machinery, marine, and other fields, with a series of frontier power products drawing on-site attention.
WP17T Methanol Engine
Developed specifically for heavy equipment such as 130-ton hybrid mining trucks and 85–135-ton mining excavators, it not only greatly reduces polluting emissions but also achieves a breakthrough of up to 40% lower fuel costs, a powerful tool for the green transformation of mining.
SOFC Power System
As a brand-new solution for distributed power and microgrids, it offers advantages of high efficiency, low carbon, continuous stability, and quiet operation, perfectly fitting scenarios such as data centers.
All-New 6WH17 Methanol Engine
Paired with Weichai's self-developed ECU control system for precise control and complete combustion, it overcomes the corrosion challenge methanol poses to engine components, truly achieving green, eco-friendly, efficient, and reliable performance, continuously contributing to the green transformation of water transport.
With power as the foundation, moving toward green. As the global energy-structure transition and dual-carbon goals accelerate, amid the era's proposition of powertrain diversification, Weichai will continue to deepen core technologies, uphold the low-carbon development path, and drive the global power industry toward efficiency, low carbon, and intelligence.
