What are the primary differences between the PC2S engine and existing two and four-stroke engines and what does that have to do with HEAT?
Heat is good. Heat is energy. Heat from burning fuel causes the air and combustion products to rapidly expand and drive the piston down the cylinder with great force. Unfortunately, of all the heat energy contained in a unit of fuel, only a fourth is available at the engine output shaft for the work of moving a vehicle. The rest is lost to inefficient combustion, internal engine friction, to the engine cooling system, and to the atmosphere through the exhaust. While it is thermodynamically impossible to eliminate all, or even most, of the heat lost through the exhaust and still generate adequate power, much of the energy lost to inefficient combustion, friction, and cooling can be recaptured by improving fuel/air mixing, increasing combustion time, reducing internal engine friction and by eliminating the need for a cooling system. The PC2S engine does all of these increases mixing, increases the elapsed time available for combustion, reduces internal friction, and eliminates the coolin
