Description
Data logging is the collecting of data and parameters over time. This is useful when looking at how something is operating in real world conditions. The Minnesota Department of Natural Resources is interested at looking at the efficiency and emissions of their propane powered lawnmowers over their gasoline powered counterparts. Using the data collected, it can then be used to recreate a similar situation in a lab to do further testing. The scope of the project is to create a data logger that will be used on small engines. The data logger has to be portable to be attached to the engine while in the field. The data to be taken from the engine is the RPM and amount of air being consumed by the engine in Cubic Feet per Minute (CFM). By data logging this information, the volumetric efficiency and the amount of load that is experienced can be calculated. This information can be used to recreate a similar cycle in the lab. This can be used to make a load curve or a series of different average load points to represent field usage. This data can then be transferred to an engine or chassis dynamometer and the engine can be subjected to a situation the same as real world. From this, an emission test cycle can be ran and is tailored specifically to the usage of the engine. The emissions can then be collected and compared from the engine when using gasoline and then propane.
