Today we have guest blogger, Engineer Laura Larsen, reviewing uses and specifications for Michigan Scientific’s Volumetrics Instrumentation.
Determining Performance and Fuel Efficiency
Michigan Scientific Corporation (MSC) has been making Volumetrics Instruments for over 20 years and is one of the leaders in the industry, selling these units to companies all over the globe. These instruments are used to accurately measure cylinder volume using acoustic technology. The user-friendly system requires the operator to simply remove the spark plug, mount an adapter, and insert a probe in the cylinder. This tool replaces traditional methods that historically provide readings that are time consuming and influenced by human error. In addition to volume, the Volumetrics Instruments are also used to determine the compression ratio of a chamber, using the volumes at top dead center and bottom dead center. With growing concern about fuel economy, compression ratio is a key variable in determining the performance and fuel efficiency of an engine.
CompRatio-D4(E) Specifications and Uses
MSC has recently launched the CompRatio-D4(E) system. The new model replaces the previous pneumatic system with an acoustic, non-pneumatic version for measurements on volumes from 15 to 1200 cubic centimeters.The D4(E) boasts a temperature range of 0-40 degrees Celsius and a humidity range of 0-95%, allowing the user to take measurements on both hot and cold engines. The innovative digital technology allows for a shorter probe and measurements can now be conveniently taken in tight spaces. Michigan Scientific Corporation’s D4(E) is a standalone system that makes quick measurement of the volume of the combustion chamber possible without disassembly of the engine and requires only an AC voltage power source. As such, the D4(E) system is well suited for laboratory development, manufacturing quality verification, and competitive bench-marking. The D4(E) system can be used for other field measurements as well such as verifying compression ratio and monitoring changes over time. The new digital display provides the user with readings in seconds. Highly calibrated reference volumes are provided with the system so the user can quickly verify the health probe before taking critical measurements.
If you are interested in this product, please reach out to a Michigan Scientific engineer today to discuss your application. The plug adapters and reference volumes are made to order. You will need to specify the adapter thread, reach, and seat of the intended spark plug as well as the desired bore, volume, and material type of the reference volume. The reference volumes are available in stainless steel and titanium.
