DETAILED DESCRIPTION The preferred embodiments of the invention are illustrated below in conjunction with the accompanying drawings. It is to be understood that the preferred embodiments described 15 herein are only for illustrating and explaining the invention and do not limit it. By means of oil restriction of an electric-controlled system, when the vehicle is running, the electric-controlled engine oil-saving system of the present invention sets different restriction modes according to the engine performance, restricts the engine rotating speed and the oil-injection quantity, and ensures that the engine runs in the best oil consumption region, 20 thereby achieving the purpose of oil saving for a vehicle with lower costs. As shown in FIG. 1, the electric-controlled engine oil-saving system uses the electric-controlled system thermal protection policy to restrict the engine oil amount, and ensures that the engine runs in the best oil consumption region, thereby achieving the purpose of oil saving for the vehicle, which specifically includes: a thermal protection system formed 25 by the temperature sensor 1 and the engine controller (ECU) 2, and an engine oil-saving system 3 depending on the thermal protection system, wherein the engine oil-saving system 3 mainly controls the three-position selecting switch 4 of the engine oil-saving system 3 by the driver according to the three-gear power mode of the actual motion operating condition of the - 5 vehicle, and the three-gear power mode specifically is: the normal power (a full-load mode), the first gear power (a half-load mode ), and the second gear power (a void-load mode ), i.e., the temperature controlled resistance of the engine oil-saving system 3 is selectively connected in parallel to the temperature sensor 1, to change the temperature collected signal 5 value of the engine controller 2, the engine oil amount is restricted using electric-controlled system thermal protection policy, and the purpose of oil saving for the vehicle is achieved by setting different restriction modes according to the engine performance, restricting the engine rotating speed and the oil-injection quantity, and ensuring that the engine runs in the best oil consumption region, thereby achieving lower costs. 10 The temperature sensor 1 is a water temperature sensor, a fuel oil temperature sensor, an air inflow temperature sensor or an engine oil temperature sensor, the input end thereof is connected with the input end of the engine controller 2 through the temperature first temperature signal input bundle 11 and the second temperature signal input bundle 12 to form an engine thermal protection system. 15 The engine oil-saving system 3 includes: a three-position selecting switch 4, a half-load temperature control resistor 5 and a void-load temperature control resistor 6. The stationary contact of the vehicle three-position selecting switch 4 is connected to the first temperature signal input bundle 11, the movable contact of the three-position selecting switch 4 is connected to the right ends of the half-load temperature control resistor 5 and the void-load 20 temperature control resistor 6, respectively, and the second temperature signal input bundle 12 is connected to the left ends of the half-load temperature control resistor 5 and the void-load temperature control resistor 6. According to the resistance characteristic of the temperature sensor of the electric-controlled system, by connecting in parallel the half-load temperature control resistor 5 and the 25 void-load temperature control resistor 6 having a corresponding resistances at a temperature (the coolant temperature, the fuel oil temperature or the air inflow temperature are available, and now the coolant temperature is taken as an example) signal pin, the aim of artificially changing the current temperature signal value is achieved. As such, the system implements the thermal protection policy by means of the super high coolant temperature signal of the 30 electric-controlled system, thereby realizing the restriction of the engine oil-injection quantity. The system further implements the engine rotating speed restriction protection policy by -6 means of the coolant temperature signal of the electric-controlled system, thereby realizing the restriction of the engine rotating speed. Additionally, the system implements the policy of simultaneously restricting the oil amount and rotating speed by means of the engine electric-controlled system according to the coolant temperature signal. The driver selects 5 resistors (half-load temperature control resistor 5 and void-load temperature control resistor 6) with different resistances according to different running conditions. The optimized configuration is standardized by the parameters of the electric-controlled system to realize dual-gear oil saving function to enable the engine to always run in an economic oil consumption zone, thereby achieving the aim of the oil-saving device. At last, the system can 10 be automatically adjusted back to the original running state. When the vehicle does not need oil saving requirements or high power performance requirements, it only needs to place the three-position selecting switch to the empty space, and the electric-controlled system is automatically restored to the original state without any influence. As shown in FIG. 2 and FIG. 3, the whole controlling process of the system is as follows: 15 The full-load mode: i.e., when the engine oil-saving system 3 needs normal power output, according to the actual motion condition of the vehicle, the driver suspends the movable contact of the three-position selecting switch 4 to form an open circuit, that is, the temperature sensor 1 is not effected, an original signal is directly input to the engine controller 2, and the engine output power is not restricted. 20 The half-load mode: when the engine oil-saving system 3 needs the first gear power output, according to vehicle actual motion condition, the driver pushes the movable contact of the three-position selecting switch 4 upwards to connect the half-load temperature control resistor 5 so that the half-load temperature control resistor 5 and the temperature sensor 1 are connected in parallel to form a new temperature characteristic (the temperature characteristic 25 is ensured to be in the engine thermal protection temperature region in the engine controller 2 through accounting) signal to input to the engine controller 2, and using the software thermal protection function policy in the engine controller 2, the restriction of the engine maximum output oil amount (through comparing the vehicle matching calculation with the engine oil amount characteristic curve, the oil amount curve is in the engine lowest oil consumption 30 region, so that the engine runs in the oil-saving region all the time) is restricted, for example: the output oil amount restriction curve is as follows: -7 Temp. -40 0 98 99 100 101 102 103 104 105 110 130 133 134 140 150

The void-load mode: when the engine oil-saving system 3 needs the second gear power output, according to the actual motion condition of vehicle, the driver pulls the movable contact of the three-position selecting switch 4 downwards to connect the void-load temperature control 20 resistor 6 so that the void-load temperature control resistor 6 and the temperature sensor 1 are - 8 connected in parallel to form a new temperature characteristic (the temperature characteristic is disposed in the engine thermal protection temperature region, and does not overlap with the temperature region at the same time when connecting the half-load temperature control resistor 5 in parallel) signal to be input to the engine controller 2, and uses the software 5 thermal protection function policy in the engine controller 2 to achieve the maximum output oil amount restriction of the engine (the oil amount curve is located in the engine economic oil consumption region); meanwhile, using the engine temperature restriction highest rotating speed policy in the engine controller 2, the purpose of restricting the engine highest rotating speed (the engine running rotating speed is located in the engine economic oil consumption 10 region) is realized. Through the engine controller 2, under the function of the engine highest rotating speed and the maximum output oil amount at the same time, the engine is restricted to run in the economic oil consumption region, thereby achieving the purpose of saving oil for the vehicle. The values of resistance of the half-load temperature control resistor 5 and the void-load 15 temperature control resistor 6 need to be flexibly demarcated and set according to the temperature characteristic resistance curve of the temperature sensor 1 to make sure the resistance connected in parallel achieves the engine thermal protection temperature region, and each resistance thermal protection temperature region is not overlapped with each other. The output oil amount and the highest rotating speed restriction value can be flexibly and 20 accurately set according to specific vehicle requirements. Through using a principle of cooling liquid temperature thermal protection oil restriction of an electric-controlled system, when the vehicle is running, the electric-controlled engine oil-saving system sets different restriction modes according to the engine performance, restricts the engine rotating speed and the oil-injection quantity, and ensures that the engine 25 runs in the best oil consumption region, thereby achieving the purpose of saving oil for the vehicle with low costs. It should be stated that the above embodiments are only used for illustrating the invention and do not intend to limit it. Although the invention is illustrated in detail with reference to the abovementioned embodiments, a person skilled in the art shall appreciate that the technical 30 solutions of the aforementioned embodiments can be modified, or some technical features thereof can be equivalently replaced. Those modifications or replacements do not make the -9 essences of corresponding technical solutions deviate from the spirit and scope of the technical solutions of each embodiment of the present invention.
