A two-cycle engine having improved performance characteristics is disclosed. In one embodiment, the engine includes a block and a cylinder head coupled to the block, the cylinder head defining a cylinder bore and a precombustion chamber. The cylinder bore is generally closed at a top and bottom end, and the head of piston located in the cylinder bore divides the bore into a first variable volume intake chamber and a second variable volume combustion chamber. An intake port allows fresh air to be drawn into the variable volume intake chamber and be compressed by the moving piston and delivered to the precombustion chamber. Fuel is added to the compressed air, which is heated, and then delivered to the variable volume combustion chamber. In one embodiment, the piston drives a crankshaft which is mounted both for rotation and for translation. Another embodiment of the invention comprises a lubricating system for a piston, the lubricating system including passages through a rod and head of the piston and flow directing elements. Movement of the piston up and down generates a pumping effect moving lubricant through the piston for lubricating piston rings.
