@@@@A presentation of measures to improve diesel emissions, focusing on the principle of the inlet water spray to reduce NOx. A set of water-injection system is installed in the inlet of 4100QBZL turbocharged diesel engine and analyse the variation law of power performance , fuel economy and NOx when spray with different amount of water. The results show that the inlet water spray can improve engine power performance and fuel economy in certain specific conditions, NOx emissions substantially reduced.
