As the first medium-speed high-power ammonia fuel engine in China, its single cylinder power can reach 208kW, ammonia energy accounts for 85%, reducing carbon emissions by 80%, and emissions meet the national standard two-stage standard. The engine adopts low pressure electronic control multi-point injection of ammonia gas and high pressure electronic injection of diesel to precisely control the fuel supply. VTG supercharger is used to achieve accurate air-fuel ratio control within the operating range. In many aspects of power level, economy, emission, technology and reliability in the international advanced, domestic leading level.
12V240H-DFA ammonia fuel engine with high safety, equipped with dual ECU, knock control, fire control, and double-layer gas supply pipe system, can achieve diesel injection, ammonia injection and security independent control, to achieve the intrinsic safety of the engine. For the key components and systems of the ammonia fuel engine, the R&D team designed the combustion system, gas supply system, fuel mixer and other related key components of the ammonia fuel engine, and optimized the injection system of diesel and ammonia gas to maximize the combustion efficiency of the ammonia diesel dual-fuel mode.
The subsequent 12V240H-DFA ammonia fuel engine will be installed in the first ammonia fuel tug in China to realize the demonstration application of ammonia fuel engine.
