Testing and adjusting motorized power equipment
This is a highly interesting application for mini CORI-FLOWs. Several instruments of type M14 are already in use in the field to accurately adjust the 2-stroke engines for all kinds of power tools for outdoor use.
An M14 mini CORI-FLOW™ instrument
can measure fuel flows from 30 g/h...30 kg/h. The actual needed flow rate
will depend on the type of engine. For example chainsaws will use flow
rates up to 1 kg/h, and weed eaters up to 0.5 kg/h.
Because mini CORI-FLOW™ instruments are multi-variable flowmeters, density
and temperature measurement will be available at the same time. In fact
everywhere where fuel powered engines are used, this type of application
can be found. The hardest parameter to predict are unburned Hydrocarbons,
but with accurate fuel flow this is easy.
The engine testing is performed for two reasons, both of which are important. 1. Emissions, 2. Quality. Using previously collected data, it is possible to accurately correlate fuel flow to unburned Hydrocarbons, CO and CO2 and engine speed.
