Abstract
An internal combustion engines keeps the pistons at or near the Top Dead Center (TDC) for the whole time or most of the time that fuel is burning or while fuel is injected into the engine. A scotch yoke embodiment includes a curved slot to extend the piston's time at TDC. A second embodiment includes a cam on the crankshaft and a follower. The shape of the cam extends the piston's time at TDC.
Claims17
A thermodynamic cycle of operation of internal combustion engines, the improvement comprising:
- coupling at least one piston to at least one crankshaft to convert rotation of the at least one crankshaft to linear motion of the at least one piston;
- and
- holding the at least one piston at or near Top Dead Center (TDC) for at least an entire time that fuel is burning during maximum power generation.
A thermodynamic cycle of operation of internal combustion engines, the improvement comprising:
- coupling at least one piston to at least one crankshaft to convert rotation of the at least one crankshaft to linear motion of the at least one piston;
- injecting fuel into a combustion chamber of the internal combustion engines;
- and
- holding the at least one piston at or near Top Dead Center (TDC) for at least an entire time that fuel is being injected into the internal combustion engines during maximum power generation.
1 more element
An internal combustion engine comprising:
- at least one crankshaft including at least one throw;
- and
- at least one piston in at least one cylinder, the at least one piston is mechanically coupled to the at least one throw to convert rotation of the at least one crankshaft to linear motion of the at least one piston,
- wherein the coupling holds the at least one at or near Top Dead Center (TDC) longer than a convention internal combustion engine.
