Abstract
An auxiliary starter unit is disclosed for facilitating starting of a diesel engine. The auxiliary starter unit includes a heater positioned in proximity to the diesel engine to improve a starting characteristic of the diesel engine. The auxiliary starter unit also includes an inverter having an intermediate circuit. The auxiliary starter unit is further provided with an energy storage device located to receive electrical energy from the intermediate circuit, and a controlled switch having a closed state and an open state. The controlled switch is positioned to couple the energy storage device in circuit with the heater to deliver electrical energy thereto. Additionally, the auxiliary starter unit includes a heating controller in communication with the controlled switch for selectively causing the controlled switch to enter the closed state to thereby supply the heater with electrical energy at an operating voltage which is higher than the operating voltage of an electrical system associated with a vehicle driven by the diesel engine.
