Abstract
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.
