However, if at TDC the piston is allowed to stay for a longer duration, it will burn a greater percentage of the fuel and air mixture in the combustion chamber until oxygen or fuel The MYT™ (Massive Yet Tiny™) or Mighty Engine™ theoretically runs out at the end of the power stroke, thereby totally completing the combustion process and drastically lowering the exhaust temperature at the end of the exhaust stroke. 6) The ME design permits the piston dwell at TDC to be adjustable. The prototype ME is currently set at approx. 12 degrees of the crankshaft rotation, thereby approaching the perfection of a complete burn of all fuel. Its exhaust gases are much cooler. As a result: * More energy is harnessed for the same amount of fuel and air input. * There is less left-over fuel to continue to burn at the exhaust stroke. * There is less waste and pollution. 7) The higher compression ratios used in diesel engines result in greater thermal expansion of gases in the cylinder. The end result is a high percentage of fuel energy being converted into useful power. In the ME design, a compression ratio as high as 70:1 can be attained due to the absence of the restrictive reciprocating components. Specifically: ¢ The combustion chambers in the ME have no design limitations, due to the absence of valves. (The internal combustion engine is an air pump. Airflow through intake and exhaust ports is normally restricted by valves. The ME has no valves—just open ports with no restriction. Airflow action is one way.) ¢ There are no odd or brand-new parts within the cylinder. All the parts are proven designs used in reciprocating engines. ¢ The entire engine acts as a heat sink and a radiator. It is both air and oil cooled. ¢ There is no thrust-loading on piston skirts. ¢ Pistons do not touch the cylinder walls; only the rings do. ¢ Pistons travel only the same direction: No reciprocation; only stop and go. ¢ There is high rpm potential for all of these reasons. ¢ It has no cylinder heads, no cam shaft, no valves. (The ME is equivalent to the bottom end of a reciprocating engine.) ¢ Intake compression and power stroke and exhaust stroke events are happening all at the same time, so there are no load strokes. ¢ The ME design is not a rotary or a Wankel design. oo (Source: Angel Labs, tel +1 (408) 667 1979, email jin@angellabsllc.com, website http:/www.angellabsllc.com) ngel Labs, based in Lodi, California, has developed a new type of internal combustion engine known as the Massive Yet Tiny™ (MYT™) Engine or the Mighty Engine™ (ME). The MYT Engine is claimed to deliver 848 horsepower (hp) from an engine weighing just 150 pounds, which would give it a power-to-weight ratio 40 times greater than a standard internal combustion engine. The MYT Engine has the potential to replace all the existing internal combustion engines and jet engines. With 40 times higher power-to-weight ratio, low parts count, low maintenance, high mechanical efficiency and low pollution, the MYT Engine will benefit airplane, big ship, 18-wheeler, SUV and passenger car, even down to carry-on power generator applications. The MYT engine working as a pump/compressor also exceeds existing pumps/compressors in providing massive pressure, volume and flow, all in one unit. to 48 = NEXUS JUNE — JULY 2006 www.nexusmagazine.com
