Latest Patents

Hamburg's latest patents include two significant inventions:

1. **Engine with Knock Sensing Apparatus Having Multiple Frequency Tuning** - This invention features a spark ignited internal combustion engine equipped with a knock sensing apparatus. It comprises vibration sensing components mounted on engine parts to detect vibrations. The sensor is tuned to recognize vibrations at multiple acoustic cavity resonance frequencies of the engine cylinders. Unique signal processing channels analyze the sensor output for each frequency, ensuring that an engine knock signal is generated only when significant vibrations are detected across all channels simultaneously.

2. **Method of Measurement of Bulk Temperatures of Gas in Engine Cylinders** - This innovative method measures the bulk temperature of gas in a piston engine during combustion by detecting high-frequency pressure oscillations in the combustion chamber. By operating the engine to induce knocking and measuring the frequency of the lowest mode in the knock signal, the temperature of the gas can be inferred, allowing for better performance monitoring and control.
