摘要： A mass-flow throttle for highly accurate control of gaseous supplies of fuel and/or air to the combustion chambers for a large engine in response to instantaneous demand signals from the engine's engine control module (ECM), especially for large spark-ignited internal combustion engines. With a unitary block assembly and a throttle blade driven by a non-articulated rotary actuator shaft, in combination with control circuitry including multiple pressure sensors as well as sensors for temperature and throttle position, the same basic throttle concepts are suited to be used for both mass-flow gas (MFG) and mass-flow air (MFA) throttles in industrial applications, to achieve highly accurate mass-flow control despite pressure fluctuations while operating in non-choked flow. The throttle, in combination with the sensors and ECM, enable detection of backfire events, with the throttle system further being enabled to take operative measures to prevent damage to the throttle components resulting from a backfire event.

摘要： Systems and methods for automatic calibration of large industrial engines in applications where the quality of the fuel supply is unknown and/or variable over time, particularly engines that drive compressors on a natural gas well site. A combination of throttles and an oxygen sensor including a mass-flow-air throttle and a mass-flow-gas throttle to determine the mass flow of air and mass flow of gas. As a response to exhaust gas oxygen level readings, the mass flow measurements are used to determine real time air-fuel ratios. An algorithm uses the air-fuel ratios as input data, wherein a microcontroller adjusts the throttles to meet engine performance demands. Additionally, using the air-fuel ratio data and suggested engine OEM calibration specifications as block multiplier inputs, particular fuel properties, such as British Thermal Unit (BTU) content, can be accurately interpolated, thereby enabling automatic calibration of the engine.

摘要： A mass-flow throttle for highly accurate control of the gaseous supplies (fuel and/or air) to the combustion chambers for a large engine in response to instantaneous demand signals from the engine's ECM, especially for large (i.e., 30 liters or greater in size) spark-ignited internal combustion engines fueled by natural gas. With a unitary block assembly and a throttle blade driven by a non-articulated rotary actuator shaft, in combination with tight control circuitry including multiple pressure sensors as well as sensors for temperature and throttle position, the same basic throttle concepts are innovatively suited to be used for both MFG and MFA throttles in industrial applications, to achieve highly accurate mass-flow control even despite pressure fluctuations while operating in non-choked flow.
