STARTING A GASEOUS AND PILOT FUELLED ENGINE |
摘要 |
<p>Starting a gaseous fuelled engine employing a pilot fuel at cold temperatures is challenging due to reduced ignitability and combustion efficiency of the fuel(s), and the increased viscosity of engine oil. A technique for starting a compression ignition, gaseous fuelled internal combustion engine employing a pilot fuel comprises determining one of a normal start condition and a cold start condition; during the normal start condition, introducing the pilot fuel into a combustion chamber of the internal combustion engine when the pilot fuel pressure rises above a first pressure; during the cold start condition, introducing the pilot fuel into the combustion chamber when the pilot fuel pressure rises above a second pressure that is higher than the first pressure; and selectively introducing the gaseous fuel into the combustion chamber.</p> |
