The piston is connected to the crankshaft via a connecting rod, while the crankshaft is disposed between the wrist pin and the combustion chamber. This way the combustion is shifted to the slow dead center, enabling the diesel to perform at higher revs, improving the spark engine efficiency and making HCCI combustion easier. Though the crankshaft is of one piece, more connecting rods can be used for a piston. As opposed piston, the PRE engine further combines top specific power, top thermal efficiency, built in scavenging pumps, and compactness. |
