An Ideal Otto Engine is one which maximizes the potential energy of the fuel using a high compression ratio and constant volume combustion.
OTTO 3G TM describes our engine as the third generation of Otto cycle engines. The first was the free piston with variable stroke and compression ratio, the second was the four cycle crankshaft fixed-stroke and compression, and now the OTTO 3G TM engine combines the best properties of the prior two designs.
Our engine utilizes homogeneous charge compression ignition, similar to the compression ignition of Diesel engines but without the typical flame front or the high levels of incomplete combustion by-products such as soot and various oxides.
Further, our patented design allows for an indeterminate stroke in all four phases of the Otto cycle, overcoming ignition and power extraction limitations imposed by all crankshaft-based engines.
