<span style="font-family: Trebuchet MS, sans-serif; font-size: large;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;">I would like to see the science and engineering world advancing beyond the "stand-alone" application of the Otto, Diesel, and Rankine cycles that waste more than half of the energy content of the fuel to the environment. </span><br />
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;">Combined heat and power (CHP) and cogeneration/trigeneration facilities cascade energy from one stand-alone system to another system to recover energy. </span><br />
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;">An ideal situation of using efficient stand-alone systems is the usage of the exhaust energy from the internal combustion system to become the input energy to </span><span style="font-family: Trebuchet MS, sans-serif; font-size: large;">heat pumps that perform chilling and heating. Since heat pumps "amplify" energy, the total net work output can be more than that which could come from the fuel alone. </span><span style="font-family: Trebuchet MS, sans-serif; font-size: large;">T</span><span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;">he Coefficient of Performance (COP), which is the "quantity of energy moved from a lower state to a higher state, E(c)" <i>divided</i> by the "input energy, E(i)" determines the amplification factor. The amount of "energy released by the heat pump, E(o)" is the sum of E(i) and E(c). Note that output, E(o), is larger than the input, E(i), thus amplified. This is because heat pumps harvest energy from the environment.</span><br />
<span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;"><br /></span>
<span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;">The example above combines two efficient stand-alone systems.</span><br />

<span style="font-family: Trebuchet MS, sans-serif; font-size: large;">My question is this: "<i><b>Could we bring some of the waste energy of an internal combustion engine back to the combustion chamber to augment the energy of the fuel?</b></i>"</span><br />
<span style="font-family: Trebuchet MS, sans-serif; font-size: large;"><br /></span><span style="font-family: Trebuchet MS, sans-serif; font-size: large;">My answer is: "<i><b>Definitely, YES! Why not? My estimates are rather promising.</b></i>"</span><br />

<li><span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;">I would combine the two gas cycles with Rankine.</span></li>
</ul>
<ul>
<li><span style="font-family: Trebuchet MS, sans-serif; font-size: large;">My design becomes </span><span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;">a hybrid of existing power cycles to increase the enthalpy available during the power stroke.</span></li>
</ul>
<ul>
<li><span class="Apple-style-span" style="font-family: 'Trebuchet MS', sans-serif; font-size: large;">The resulting temperature of the combustion chamber would be slightly reduced, thus inhibiting the production of NOx.</span></li>
</ul>
