Abstract
The present invention relates to the design of fuel powered heaters for automotive or vehicles application. The furnace consists essentially of a blower, and a fuel pump driven electrically from the battery of the vehicle, a swirler to optimize mixture of air and fuel, a combustion tube to burn the fuel:, a heat exchanger to transmit the generated heat into a water conduit to heat up in turn the engine of the vehicle, and a rotating turbine on the exhaust to furnish electricity back into the battery of the vehicle or the electric motor which drive the blower and pump. Where heating is not required for the engine through a water conduit, as an alternative air may be used as a medium to exchange heat with the cabin of the vehicle or its engine compartment.
Description
~ 156q~0 2 . O DESCRIPTION OF THE CONCEPT
20 In the last few years it has become recogni~ed that idling an engine of a vehicle simply to produce heat was detriment to the life of the engine and was a source of unwanted pollution. Small mini-furnace have been developed to operate on the fuel of the vehicle as a source of auxiliary heat for the engine block or the 25 cabin of tke vehicle . These furnaces eliminate the need to idle the engines of the vehicle Most mini-furnaces operate on the concept of using one or more direct current motors to drive the blower, fuel pump and compressor 30 for adequate combustion of air and fuel. Electric power for these rotating elements is drawn directly from the batteries of the vehicle T~lis tends to drain the energy of the battery if the mini-furnace is used extensively without turning the main engine on to recharge the batteries once every few hours.
To remedy to this problem of draining the battery from its energy the inventors came up with the concept of designing a special turbine compartment on the exhaust of the furnace to regenerate sufficient electricity for continuous operation. Such a turbine 40 would be coupled to a direct current generator . The electric current thus generated may be delivered directly to the motors of the heater or alternatively to the battery of the vehicle.
The energy that is available on the exhaust for the auxiliary power 45 turbine depend on the efficiency of conversion of heat from the heat exchanger, and the amount of heat transfer, the efficiency of combustion and the air/fuel ratio of the mixture. Typically the energy required to drive th~ fan and pump is inferior to 5% of the heat generated by combustion of the mixture. It is therefore 50 conceivable that sufficient waste heat would be available on the exhaust to drive a turbine and a small generator as a feedback current to the motor(s) of the fan, pump and compressor of the heater.

Whereas the heat generated by heater is exchanged with the engine block via a water loop, the generator of the turbine module must be deslgned to supply sufficient electric current to operate the heater and the water pump for the water loop Whereas the heat generated by heater is ~x,changed with the vehicle cabin or englne compartment via an air space heater, the generator of the turbine module must be designed to supply sufficient electric current to operate the heater and the blower for blowing hot air into the cabin and engine compartmelrt.
Thus referring to fig(l) which shows an embodiment of the invention . Starting at the eye of the fan ( 1 ) air is pumped into the heater electric chamber ( 2 ) by a blower fan ( 1 ) operated by an electric motor (3). The electric motor (3) drives a fuel module (4) containing a fuel pump (5) . On the discharge of the fuel pump, a nozzle (6) ensures atomization of the fuel into fine particles inside the combustion tube ( 7 ) of the heater At the entry to the combustion tube a swirler (8) ensures appropriate rotation of the air into a vortex thus ensures appropriate dispersion and mixing of fuel with air. The mixture is ignited by the i~nition coil (9) and the electrode(s) (10) of the heater. The hot gases from the combustion of the air-fuel mixture exchange their heat with the engine water loop or with the cabin space heater via the heat exchanger (11). At the exhaust from the heat exchanger, the hot air is directed into the volute (12) of a turbine (13) for the generation of auxiliary power via a generator (14).
Referring to fig (2) Auxiliary power from the generator (14) may be connected back into the battery of the vehicle ( 15 ), the heater motor (3), a water pump (16) for the engine block if the heater is used to warm up the engine, or the blower (17) of a space heater if the heater is used for production of cabin heat During summer operation or during operation in areas of hot climatic conditions, electricity from the auxiliary power unit may be used to operate the air conditioning system of the vehicle without turning on the main engine heater This approach requires however that some of the heat of the heater be dumped into the radiator of the engine where an electric fan achieves further dissipation of heat to the environment.
