Ammonia is considered a potential carbon-free alternative to fossil fuels. However. its unfavorable combustion characteristics and propensity to form fuel NOx pose a challenge for its use as fuel for internal combustion engines. The high-pressure dual fuel (HPDF) direct-injection of ammonia could offer the potential to reduce ammonia slip and decrease NOx formation. https://www.marketingjeunesse.com/product-category/primer/
