    Abstract: An engine preheating system supports starting industrial and/or diesel engines in cold weather, eliminating the need for cold weather idling. The system preheats the engine coolant, bringing the entire machine up to a warm starting condition. This provides good lubrication and immediate heat availability. The system is fully portable and does not rely on commercial power, operable at any location. The system utilizes propane fuel, which is widely available. The propane fuel burns quietly and cleanly as opposed to fuel oil. The system includes numerous safety features, such as flow indicators and modern microprocessor technology to ensure safe operation.
