This application is a continuation in part of U.S. patent application Ser. No. 11/698,649, “Motor Oil Heating System, Product and Method,” filed Jan. 25, 2007, which is hereby incorporated entirely herein by reference.
BACKGROUNDThe subject matter herein relates generally to a system and method for heating engine motor oil and thereby improving engine fuel efficiency. Further, the subject matter also relates generally to a means for electrically coupling a heating element to one or more power sources to directly or indirectly heat the engine motor oil. The present disclosure relates more specifically to a solar means of heating engine motor oil for providing improvements in engine fuel efficiency.
One aspect of the current invention involves lubricants, such as motor oil, and the affect on engines of the lubricants over varying temperatures. The basic performance of an engine or other machinery is based on the viscosity of the lubricant. Viscosity is the resistance to the flowability of the oil. The thicker an oil, the higher its viscosity. Multigrade motor oils work by having a polymer added to a light base oil which prevents the oil from thinning too much as it warms up. At low temperatures, the polymers are coiled up and allow the oil to flow. As the oil heats up, the polymers unwind into long chains which prevent the oil from thinning as much as it normally would.
The viscosity index (VI) of a lubricant is an empirical formula that allows the change in viscosity caused by heating to be calculated. The higher the viscosity index, the less an oil will thin at a specified temperature. Multi-viscosity motor oils will have a viscosity index well over 100, while single viscosity motor oils and most industrial oils will have a VI of about 100 or less.
The viscosity of an engine's oil and the performance of an automobile are related. If the viscosity is too high for the ambient temperature, the oil pump will have to work too hard to deliver the oil and result will be a lower fuel efficiency as measured in miles per gallon (MPG). Conversely, if the oil viscosity is too low then the engine will have an excessive amount of internal friction also resulting in a lower MPG.
As such what is needed is a system and method for ensuring motor oil is at an appropriate temperature for efficient engine operation.
SUMMARYThe present disclosure is directed to a motor oil heating system which improves fuel efficiency. The invention provides for a motor oil heating system for a vehicle which utilizes solar panels comprised of photovoltaic cells and a heater physically connected to an oil reservoir, an oil pan or transmission block containing motor oil. The solar panels are electrically coupled to the heaters and power the heaters based on a voltage generated by the solar panel such that the heaters warm the engine oil. By heating the engine oil, the viscosity of the oil is reduced which allows for the engine to run more efficiently.
In another embodiment, heaters may also be thermally coupled to the motor oil. In one embodiment, a heating pad may be affixed to the exterior of an oil pan. Alternatively, a heater may be physically positioned to enter into the interior of an engine block or oil pan. In another embodiment, a battery may be electronically coupled to a control module, solar panel and heater. The control module serves to switch power to the heater between the battery and the solar panel. In certain aspects, the control module may be a timer.
Additionally, a battery and solar panel may be electrically coupled together with a voltage regulator utilized to control power between the battery, solar panel and the heater in another embodiment. The voltage regulator is utilized to control the power to the heater based upon the solar panel output and the charge of the battery. If there is insufficient light for powering the heating pad, a control module may be used to provide an alternative energy source. The control module is electrically connected to a power supply and allows for power to the heaters to be switched between a power supply and the solar panel. Further, a temperature probe may be utilized as a sensor to determine if the oil is below a predetermined value. Should the oil fall below this predetermined value, the circuit is closed which allows current to pass into the heating element to heat the oil. When the oil reaches the predetermined temperature, the probe senses the temperature and opens to shut off the current to the heating element.
In another embodiment of the invention, a timer and battery may be coupled to the solar panel and heater in order to heat oil in the transmission or motor of a vehicle. A solar panel is electrically connected to a battery, which in turn is electrically connected to a timer. The timer controls the heater which is physically coupled to the motor oil. The solar panel charges the battery until the battery contains enough power to operate the heater. The timer directs power to the heater and also provides for charging the battery such that the heaters heat the motor oil thus reducing the viscosity of the oil and facilitating pumping the motor oil when the engine initially begins to operate.
Another embodiment may be configured so as to utilize the ignition of a vehicle to facilitate the heating of motor oil. Here, the vehicle ignition is electrically coupled to a control module, which is in turn electrically coupled to the battery. The battery is configured to provide an electric charge to the heater so that the motor oil will begin to heat as the vehicle starts. As an example, the control module may be a switch and is activated by an ignition component. Additionally, a plug may be electrically coupled to the battery in order to provide an electrical charge to the battery.
Another embodiment provides for a method of increasing fuel efficiency comprising certain steps which may be performed in any order. The following is an example of an order of steps for such a method: (1) connecting at least one heater to an oil reservoir of the engine, and (2) coupling the heating element to one or more solar panels, so that when the engine is not operating, the temperature of the oil is raised above ambient temperatures reducing the viscosity of the oil thus facilitating pumping the oil when the engine initially begins to operate.
Another embodiment provides for a method of increasing fuel efficiency comprising certain steps which may be performed in any order. The steps in any order: (1) thermally coupling at least one heating element to an oil reservoir of the engine; (2) coupling the heating element to one or more control modules; and (3) coupling the control modules to one or more solar panels, such that when the engine is not operating, the temperature of the oil is raised above the ambient temperature reducing the viscosity of the oil thus facilitating pumping the oil when the engine initially begins to operate. Here, the control module may be a timer utilized to provide power to a heater at a predetermined interval such that the oil is not continuously heated.
Another embodiment provides for a method comprising certain steps which may be performed in any order. The steps: (1) thermally coupling at least one heating element to an oil reservoir of the engine; (2) coupling the heating element to one or more power sources, so that when the engine is not operating, the temperature of the oil is raised above ambient temperature reducing the viscosity of the oil thus facilitating pumping the oil when the engine initially begins to operate. In this embodiment, the power source may be a solar panel comprising one or more photovoltaic cells. Alternatively the power source may be 120 VAC power. Additionally, the heating element is coupled to the power source though a control module so that power sources may be connected to the heating element. In the present embodiment, the control module may be a timer, a voltage regulator, or a switch. Further, the heater may be a heating pad.
An other embodiment provides for an additional method of increasing fuel efficiency of an engine comprising certain steps which may be performed in any order. The steps: (1) connecting at least one heating element to an oil reservoir of the engine; (2) coupling the heating element to one or more solar panels; and (3 such that the cold start temperature is greater than the freezing point of the oil. Thus, when the engine is not operating, the temperature of the oil is raised reducing the viscosity of the oil thus facilitating pumping the oil when the engine initially begins to operate. With such a method, the increased fuel efficiency is maximized in a temperature range from about a cold start temperature of greater than 32 degrees Fahrenheit to an optimal heated temperature of 112 degrees Fahrenheit.
This disclosure provides for a motor oil heating system for a vehicle comprising one or more solar panels each comprised of one or more photovoltaic cells; one or more heaters thermally coupled to the motor oil, wherein the solar panels are electrically coupled to the heaters and power the heaters based on a voltage generated by the solar panel such that the heaters warm the engine oil.
The construction and method of operation of the invention, together with additional objectives and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.
A single solar cell normally produces voltage and current much less than the typical requirement of a heating element. A photovoltaic cell typically provides 0.2-1.4 V and 0.1-5 A, depending on the photovoltaic cell and its operating conditions, e.g. direct sun light, cloudy, etc., while the electrical load most likely requires a greater operating voltage and current. Thus a number of photovoltaic cells are arranged in series to provide the needed voltage requirement, and arranged in parallel to provide the needed current requirement.
One having skill in the art will recognize that there are many ways to effect the collection of solar power and conversion into electricity. For vehicles, a thin film flexible solar panel may be used to conform to existing vehicle designs so that environmental and operating conditions are not adversely affected.
There are many types of heating elements known in the art. A heating element converts electricity into heat through the process of Joule heating. Electrical current running through the element encounters resistance, resulting in heating of the element. One having skill in the art would recognize that thermally coupling the heating element to the vehicle oil requires selection of an appropriate means so that the oil, which may be flammable, it not overheated. The heating element 14 may be thermally coupled by attaching it to the exterior of the oil pan using a variety of means.
This invention provides increased fuel efficiency by heating the engine oil from a “cold start” temperature, which is determined by environmental settings, to a temperature where the oil viscosity is reduced such that pumping the oil through the engine is facilitated. The cold start temperature may be determined by the ambient temperature or the other factors wherein the oil temperature is below its optimum viscosity. One having skill in the art will appreciate that the further from the optimum operating temperature the oil is, the more fuel efficiency can be increased with the current invention. Also one having skill in the art will appreciate that the current invention may be used for motor oil, for transmission oil or other fluids where increasing their temperature increases overall engine efficiency.
The benefit to the current invention is that the engine oil is warmed using energy from renewable sources. Since it is easier for an engine to pump a warm oil than a cold oil, the engine will have less of a load and consequently consume less power. In effect this invention provides increased fuel economy by reducing gasoline consumption for the same engine performance.
