    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.

    摘要： An exhaust gas recirculation (EGR) system for an internal combustion (IC) engine. The EGR system has a first cooler configured to cool exhaust from an exhaust system of the IC and to drain exhaust liquid formed by the cooling. The EGR system has a mixture chamber configured to mix exhaust cooled by the first cooler with intake air to form an exhaust-air mixture. The EGR system has a second cooler configured to cool the exhaust-air mixture. The EGR system has a heat exchange system for circulating and cooling coolant fluid used by the first and second coolers, and includes a split valve configured to divide coolant fluid flow between the first and second coolers. The EGR system has an engine control module configured to adjust the split valve based on comparing a temperature of the exhaust-air mixture to a determined dewpoint temperature of the exhaust-air mixture.

    摘要： Many embodiments involve rechargeable battery assemblies that are forklift-battery-sized but that comprise multiple removable battery modules. The removable battery modules are individually rechargeable and are interchangeable with each other. A housing contains six battery modules installed vertically on the front side of the assembly, with their electrical and data connections occurring within the housing on the rear side. Assemblies will be two sided so that the system has two racks with six modules per rack. The handles of each module are collapsible and on the top edges of the overall assembly so that they are readily accessible during removal. Each battery module has an integrated battery supervisor system (BSS). A Battery Operating System Supervisor (BOSS) module processor serves as a battery management system for the all the battery modules. The BOSS module grants permissions to battery modules to enable them to connect and disconnect from busbars at the appropriate times to prevent electrical issues.
