摘要 |
The invention resides in an internal combustion engine (20) comprising an air intake system (24) operatively connected to a cylinder (21), a gaseous phase fuel delivery system (25) operatively connected to the cylinder (21), and a liquid phase lubricant injection system (10) operatively connected to the cylinder (21). An atomised portion of liquid phase lubricant is injected into a mixture of gaseous phase fuel and air by the liquid phase lubricant injection system (10) to lubricate components of the cylinder (21) prior to burning the mixture in the cylinder (21).
