Abstract
An automated system for managing temperature and reducing crankcase oil dilution in an internal combustion engine. The system includes a rotatable shutter plate having an open portion, a closed portion and a peripheral rim, the peripheral rim having a frictional surface thereon; a motor having a rotatable shaft having a pinion affixed at one end thereof for engagement with the frictional surface of the peripheral rim of the rotatable shutter plate; and a temperature sensor for monitoring a temperature indicative of engine warm-up and sending a signal to a controller; wherein the rotatable shutter plate is structured and arranged to at least partially occlude an air inlet to or outlet from the internal combustion engine when rotated in response to a signal received from the controller. A method of reducing crankcase oil dilution and managing temperature in a spark-ignited engine operating on middle-distillate fuel and a portable engine or engine-generator combination having multi-fuel capability are also provided.
