Engineers Designed Nearly Zero Emission Diesel Engine

Engineering team unveils next generation diesel engine technology that minimizes fuel consumption and reduces NOx and CO2 emissions by 90%.

Authorities in most countries are gradually introducing stricter emission limits for vehicles. Therefore, an interdisciplinary team of researchers from the Southwest Research Institute of San Francisco decided to use a systems approach to modify the internal combustion engine..

Over the years, engineers have developed a more powerful version of the 2017 Cummins X15 diesel engine with virtually no pollution. To achieve the desired results they modified its architecture, added a post-processing system and improved controls.

Researchers have already evaluated the performance under low load conditions, and the system is currently being tested under real operating conditions such as hydrothermal stress and catalyst fouling. Early tests showed that nitrogen oxide and carbon dioxide emissions were 90% lower than the base model.

Earlier, we also reported on the development of an electro-hydraulic valve system that saves 20% fuel by optimizing gas exchange in a spark-ignition ICE..
