Abstract

There is disclosed a system for use in transport vehicles, comprising in combination an auxiliary power unit (APU) for a transport vehicle powered by a diesel engine and having a fuel system, an engine exhaust system and a battery powered electrical system; and a locator unit for use in a tracking and monitoring system for communicating over a communication network with the locator unit and with a remote location the APU, wherein the locator unit is attached to or installed within the APU. In another aspect there is disclosed an auxiliary power unit (APU) for a transport vehicle comprising an enclosure for housing and supporting the auxiliary power unit on the transport vehicle; an air-cooled diesel engine directly driving an air-cooled, brushless generator providing direct, simultaneous AC and DC voltage outputs; first and second air duct systems within the enclosure for separately conveying cooling air into and through the air-cooled, single cylinder diesel engine and the generator respectively; and an engine exhaust adapter wherein engine exhaust from the air-cooled diesel engine is directly coupled through the exhaust adapter installed in-line with an exhaust pipe of the transport vehicle between the engine of the transport vehicle and the muffler of the transport vehicle.

Dependent claims

A system for use in transport vehicles, comprising:

an auxiliary power unit (APU) for a transport vehicle powered by a diesel engine and having a fuel system, an engine exhaust system and a battery powered electrical system, the APU comprising:
an air-cooled diesel engine configured for operation using the fuel supply and the engine exhaust system of the transport vehicle, and having an integral, forced-air cooling system;
an air-cooled, brushless generator directly coupled to an output shaft of the air-cooled diesel engine and providing simultaneous high voltage AC and low voltage DC outputs without using an inverter or a converter and having an integral, forced-air cooling system;
an enclosure surrounding the air-cooled diesel engine and the air-cooled brushless generator, for protection and mechanical support;
and
a system of first and second air ducts within the enclosure to separately convey cooling air into and through the air cooled diesel engine and the air cooled brushless generator respectively, to exit through first and second respective air outlets from the enclosure, wherein cooling inlet air is drawn into the first and second air ducts by respective direct drive fan means integrated respectively in the air cooled diesel engine and in the air cooled brushless generator;
and
a locator unit, for use in a tracking and monitoring system for communicating over a communication network with the locator unit and with a remote location, wherein the locator unit receives, stores and transmits data about the APU and the engine of the transport vehicle in combination with location data of the transport vehicle, and wherein the locator unit is attached to or installed within the APU.

An auxiliary power unit (APU) for a transport vehicle powered by an internal combustion engine, comprising:

an enclosure for housing and supporting the auxiliary power unit on the transport vehicle;
an air-cooled diesel engine having an output shaft and enclosed within the enclosure with and directly driving an air-cooled, brushless generator having an armature shaft, wherein the air-cooled diesel engine utilizes fuel supply, exhaust and electrical systems of the transport vehicle engine and the generator provides direct, simultaneous AC and DC voltage outputs without requiring an inverter or a converter circuit;
first and second air duct systems within the enclosure for separately conveying cooling air into and through the air-cooled, single cylinder diesel engine and the generator respectively, to exit through first and second respective air outlet ducts from the enclosure, wherein cooling inlet air is drawn into the first and second air duct systems by respective direct drive fan means integrated respectively in the air-cooled, single cylinder diesel engine and in the generator;
and
an engine exhaust adapter wherein engine exhaust from the air-cooled diesel engine is directly coupled through the exhaust adapter installed in-line with an exhaust stack pipe including a muffler of the transport vehicle between the engine of the transport vehicle and the muffler of the transport vehicle.
