    DETAILED DESCRIPTION
    The preferred embodiments of the invention will now be described in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation of the invention only and not limiting.
    By limiting the oil level of an electrically controlled system with the vehicle running, the electrically controlled engine oil saving system of the present invention sets different limit modes according to engine performance, limits engine speed and oil injection quantity, and ensures that the engine is operating in the best oil consumption range, so that the goal of oil saving is a vehicle is achieved at a lower cost.
    As shown in FIG. As shown in FIG. 1, the electrically controlled engine oil saving system utilizes a thermal protection measure of the electrically controlled system to limit the amount of engine oil and ensures that the engine is operating in the best oil consumption range so that the goal of oil saving for the vehicle is achieved specifically, a thermal management system formed by the temperature sensor 1 and the engine control unit (ECU) 2 and a thermal management system dependent engine oil-saving system 3, the engine oil-saving system 3 mainly including the engine oil-saving system three-position selection switch 4 3 by the drive according to the three-speed
    Specifically, the power mode of the actual motion operating condition of the vehicle controls, and the three-speed power mode specifically includes: the normal power (full-load mode), the first-speed (half-load), and the second-speed (no-load), d. H. the temperature-controlled resistance of the engine oil-saving system 3 is selectively connected in parallel with the temperature sensor 1 to change the sensed temperature signal value in the engine controller 2, the amount of engine oil being limited by means of a thermal protection measure of the electrically-controlled system and the target of the oil-saving for the vehicle is achieved by setting different limiting modes according to the engine output, limiting the engine speed and the oil injection amount, and ensuring that the engine runs in the best oil consumption range, thereby achieving lower costs.
    The temperature sensor 1 is a temperature sensor for water, a temperature sensor for fuel oil, a temperature sensor for air intake or a temperature sensor for engine oil whose input end is connected by the first temperature signal input beam 11 and the second temperature signal input beam 12 to the input end of the engine controller 2, to form a heat protection system for the engine.
    The engine oil-saving system 3 includes: a three-position selecting switch 4, a half-load temperature regulating resistor 5, and a zero-load temperature regulating resistor 6. The fixed contact of the three position selecting switch 4 is connected to the first temperature signal input beam 11, the movable contact of the three position selecting switch 4 is connected to the right ends of the temperature control resistor 5 for half load and the temperature regulating resistor 6 for no load, and the second temperature signal input beam 12 is connected to the left ends of the half load temperature control resistor 5 and the zero load temperature control resistor 6.
    In accordance with the resistance characteristic of the temperature sensor of the electrically controlled system, the object of artificially changing the current temperature signal value is achieved by establishing a parallel connection with the half load temperature control resistor 5 and the zero load temperature control resistor 6 which provide a corresponding resistance in a temperature signal pin have (coolant temperature, fuel oil temperature or air inlet temperature available, and now the coolant temperature is taken as an example). In this sense, the system implements the heat protection measure by means of the signal for a particularly high coolant temperature of the electrically controlled system, so that the limitation of the oil injection amount for the engine is performed. The system further implements a protective measure by limiting the engine speed by means of the coolant temperature signal of the electrically controlled system, so that the limitation of the engine speed is performed. In addition, the system implements the measure of simultaneously limiting the amount of oil and the speed by means of the electrically controlled engine system according to the coolant temperature signal. The drive selects resistors (temperature control resistor 5 for half load and temperature control resistor 6 for no load) with different resistance values according to different operating conditions. The optimized configuration is standardized by the parameters of the electrically controlled system to implement a two-speed oil saving function, so that the engine can always run in a fuel-efficient oil consumption zone, thereby achieving the goal of the oil conserving device. Finally, the system can be automatically returned to its original operating state. If the vehicle has no oil saving requirements or high performance requirements, the three position selector switch need only be placed in neutral, and the electrically controlled system will automatically be returned to its original state without interference.
    As shown in FIG. 2 and FIG. 3, the entire control process of the system proceeds as follows:
    Full load mode: When the engine oil-saving system 3 needs a normal output power according to the actual moving condition of the vehicle, the drive releases the movable contact of the three-position selecting switch 4 to form an open circuit, that is to say. H. the temperature sensor 1 is not activated, an original signal is directly input to the engine controller 2, and the output power of the engine is not limited.
    Half-load mode: When the engine oil-saving system 3 needs the first-speed output according to the actual moving condition of the vehicle, the driver pushes up the movable contact of the three-position selecting switch 4 to connect the half-load temperature regulating resistor 5 so that Temperature control resistor 5 for half load and the temperature sensor 1 are connected in parallel to form a new temperature characteristic signal (by ensuring that the temperature characteristic is in the heat protection temperature range for the engine in the engine control unit 2), which is input to the engine controller 2, and by Use of the heat protection function of the software in the engine controller 2 restricts the limitation of the maximum output oil amount of the engine (by comparing the vehicle-owning calculation with the characteristic curve for the engine oil amount, there is the oil quantity curve in the lowest oil consumption range of the engine, so that the engine runs in the oil-saving range the entire time), the curve for limiting the output oil quantity, for example, looks like this:
    Meanwhile, by means of the maximum speed measure according to engine temperature limitation in the engine controller 2, the maximum engine speed is reached (by comparing the vehicle-owning calculation with the engine oil quantity characteristic curve, the engine operating speed is in the engine low oil consumption range, so that the engine over all time in the oil saving area), where the curve for limiting the maximum speed, for example, looks like this:
    Finally, the engine, by the engine controller 2 and under the function of the simultaneous maximum output oil amount of the engine and maximum speed, is limited to running in the lowest oil consumption range, so that the target of the oil saving for the vehicle is achieved.
    No-load mode: When the engine oil-saving system 3 needs the second-speed output according to the actual moving condition of the vehicle, the driver pulls down the movable contact of the three-position selecting switch 4 to connect the zero-load temperature regulating resistor 6, so that the temperature regulating resistor 6 for zero load and the temperature sensor 1 are connected in parallel to form a new temperature characteristic signal (the temperature characteristic is heat-shielding temperature range for the engine and does not coincide with the temperature range in parallel connecting the temperature control resistor 5 for half-load), which is input to the engine controller 2 and uses the heat protection function of the software in the engine controller 2 to achieve the limitation of the maximum output oil amount of the engine (the curve for the oil amount is in the economical oil consumption range of the engine); meanwhile, by means of the maximum speed measure according to engine temperature limitation in the engine controller 2, the target of limiting the maximum engine speed is reached (the engine operating speed is in the economical oil consumption area of the engine).
    By the engine controller 2 and under the function of the maximum simultaneous engine speed and maximum output oil quantity, the engine is limited to running in the fuel-efficient oil consumption area, so that the target of the vehicle's oil-saving is achieved.
    The resistance values of the half-load temperature control resistor 5 and the zero-load temperature control resistor 6 must be flexibly limited and set in accordance with the temperature characteristic resistance curve of the temperature sensor 1 to ensure that the parallel connected resistor reaches the heat-shielding temperature range of the motor and the individual heat-shielding temperature ranges of the resistors do not overlap. The limit value for the output oil amount and the maximum speed can be set flexibly and precisely according to specific vehicle requirements.
    By using a principle of heat shield oil limitation according to a coolant temperature of an electrically controlled system with the vehicle running, the electrically controlled engine oil saving system adjusts different limit modes according to engine power, limits engine speed and oil injection quantity, and ensures that the engine is operating in the best oil consumption range so that the goal of oil saving for the vehicle is achieved at a low cost.
