Abstract: A low emission power generating apparatus which comprises a modified two-stroke diesel engine component and a modified turbocharger component which has a relatively low aspect ratio. The diesel engine component is a modification of a conventional two-stroke diesel engine design and includes a modified connecting rod assembly which causes a modified piston to accelerate rapidly within the combustion chamber and an exhaust valve cam of unique design that has a cam profile which results in a later than-normal exhaust valve opening and an earlier-than-normal valve closing so that the time during which the exhaust valve remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber following the scavenge stroke. This increase in the volume of the residual exhaust gases within the chamber leads to an increase in compression temperature and effectively increases the compression ratio and consequently the compression pressure.

Abstract: A low emission power generating apparatus which comprises a modified two-stroke diesel engine component and a modified turbocharger component which has a relatively low aspect ratio. The diesel engine component is a modification of a conventional two-stroke diesel engine design and includes an exhaust valve cam of unique design that has a cam profile which results in a later-than-normal exhaust valve opening and an earlier-than-normal valve closing so that the time during which the exhaust valve remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber following the scavenge stroke. Reduction in peak combustion temperature advantageously results in the lower than normal production of nitrogen oxide (NOx) and, therefore, allows advancement of the injection timing, while still maintaining the NOx emissions coming from the engine lower than those legislatively mandated.
