With a total of 4 patents to his name, Frobenius has developed innovative methods and apparatuses that enhance engine performance and efficiency.

Latest Patents

Frobenius's latest patents include a method and apparatus for lean burn mixture control of an internal combustion engine. This fuel mixture control system utilizes a control device that accepts signals for final correction of the fuel mixture. The final correction is based on engine roughness, which serves as a measure of the degree of lean burning. The engine roughness is determined digitally by forming second differences of engine period in sequential digital counters. The final counter is counted down at an rpm-dependent frequency, allowing for precise adjustments to the fuel mixture.

Another significant patent involves a process and apparatus for determining engine operation near the lean burn region. This innovation allows for the shortening or lengthening of fuel injection control pulses to maintain a specific fuel-air ratio. The system addresses dynamic instability that occurs during leaned-out operation, which can lead to rapid fluctuations in crankshaft velocity. By testing crankshaft speed at two different locations, the system can effectively adjust fuel injection pulses to optimize engine performance.
