<p>A two-cycle engine (20) having improved performance characteristics includes a block (22) and a cylinder head (32) coupled to the block (22), the cylinder head (32) defining a cylinder bore and a precombustion chamber (50). The cylinder bore (48) is generally closed at a top and bottom end, and the head of piston (54) located in the cylinder bore (48) 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 (54) and delivered to the precombustion chamber (50). 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 (28) which is mounted both for rotation and for translation. Other embodiments of the invention comprise an improved fuel injector (116) and lubricating system.</p> |
