Title:
【発明の名称】窒素酸化物の排出を減少させるためにガス状燃料及び乳化パイロット燃料の混合ガスによりエンジンを駆動する方法
Document Type and Number:
Japanese Patent JP2002504647
Kind Code:
A
Abstract:
Reduction of nitrogen oxide emissions during operation of an engine is achieved by using a fuel mixture therein which includes a gaseous fuel and an emulsified pilot fuel. The method includes the steps of (i) advancing air into a combustion chamber of the engine, (ii) advancing a gaseous fuel into the combustion chamber, (iii) injecting an emulsified pilot fuel into the combustion chamber, wherein the emulsified pilot fuel includes water and liquid fuel, and (iv) compressing a mixture which includes (A) the air, (B) the gaseous fuel, and (C) the emulsified pilot fuel within the combustion chamber during a compression stroke of the engine, whereby heat generated by compression of the mixture causes the emulsified pilot fuel to combust so as to ignite the gaseous fuel.
