摘要： A system and method for providing auxiliary power to a large diesel engine allowing shutdown of such large engine in all weather conditions. An auxiliary power unit made up of a secondary engine coupled to an electrical generator is provided. An automatic control system shuts down the primary engine after a period of idling and the auxiliary power unit provides electrical power for heating and air conditioning. In cold weather, the auxiliary power unit maintains the primary engine coolant and lube-oil warm to facilitate engine restart. The coolant system is kept warm using a heat exchanger and electrical heaters. The lube-oil system is kept warm using a recirculating pump and electrical heaters. In warm weather, the auxiliary power unit provides electrical power for air conditioning and other hotel loads. The auxiliary power unit isolates the primary engine batteries during operation and provides electrical power for hotel and non-vital loads.

摘要： Systems and methods for providing auxiliary power to a large diesel engine allow shutdown of the engine in various weather conditions. An auxiliary power unit (APU) comprising a secondary engine coupled to an electrical generator is provided. An automatic control system shuts down the primary engine after a period of idling, and the APU provides electrical power for heating and air conditioning. The APU automatically starts in response to a low coolant temperature, low battery voltage, and low air reservoir pressure. It may also start automatically after extended shutdown to ensure reliability. Automatic primary engine shutdown is defeated if the secondary engine is disabled.

摘要： A locomotive emissions reduction kit and method of earning emission credits enables an auxiliary power unit dedicated to a locomotive diesel engine allowing shutdown of such engine in all weather conditions, thereby significantly reducing exhaust emissions. An auxiliary power unit made up of a secondary engine with substantially lower exhaust emissions coupled to an electrical generator is provided. An automatic control system shuts down the locomotive engine after a period of idling and the auxiliary power unit provides electrical power for heating and air conditioning. In cold weather, the auxiliary power unit maintains the locomotive engine coolant and lube oil warm to facilitate engine restart. The coolant system is kept warm using a heat exchanger and electrical heaters. The lube oil system is kept warm using a recirculating pump and electrical heaters. A geographic position determination unit generates locomotive location information. Data recording instruments process and record information concerning locomotive engine and auxiliary engine activity for monitoring geographical position, emissions, and fuel levels of the locomotive engine and its corresponding auxiliary unit.
