Abstract
The utility model discloses an improved fuel oil preheating temperature control device of an internal combustion engine, which comprises an oil tank, a fuel ail preheating device and a fuel oil heating tail pipe that penetrates out from the fuel oil preheating device and is connected with a high pressure fuel oil pump with an oil return pipe. A fuel oil temperature measuring device is arranged on the fuel oil heating tail pipe or the high pressure fuel oil pump; an oil return control valve is arranged on the oil return pipe. The utility model can control the fuel oil preheating temperature, and can prevent the fuel oil preheating temperature from too high, so as to guarantee the normal operation of the internal combustion engine.
Description
Technical field
The utility model belongs to the improvement of internal-combustion engine with the fuel-firing preheating device, particularly improved fuel of internal combustion engine preheating temperature control gear.
Background technique
Usually, the temperature that improves the fuel oil of internal-combustion engine use in advance can reach the fuel consumption that reduces internal-combustion engine, the purpose of the power of content of harmful and raising internal-combustion engine in the tail gas of reduction engine exhaust, people have designed various fuel of internal combustion engine Preheating units for this reason, as the patent No. is 00268279.6, the Chinese utility model patent that name is called " the fuel-firing preheating device of internal-combustion engine " discloses the fuel-firing preheating device that a kind of high-temperature tail gas that utilizes engine exhaust among the tail gas manifold of internal-combustion engine comes the fuel oil that the preheating internal-combustion engine uses, and it can effectively utilize the fuel oil that high-temperature tail gas that engine exhaust comes out will send into before the internal-combustion engine and carry out preheating; But, in use find, this class utilizes the high-temperature tail gas of engine exhaust to come the fuel-firing preheating device of pre-heating oil all to exist when the internal-combustion engine full power is operated at full capacity as vehicle heavy duty climbing, can cause the excessive phenomenon of fuel-firing preheating is taken place, and the too high fuel oil of temperature can cause the power straight line of internal-combustion engine to descend when spending above 75 as the temperature of diesel oil.
The model utility content
The purpose of this utility model is to provide a kind of improved fuel of internal combustion engine preheating temperature control gear, can control the fuel-firing preheating temperature, prevents the too high phenomenon of fuel-firing preheating temperature, guarantees the internal-combustion engine proper functioning.
The purpose of this utility model is achieved in that a kind of improved fuel of internal combustion engine preheating temperature control gear, comprise fuel tank, fuel-firing preheating device and the fuel Heating tail pipe that from the fuel-firing preheating device, passes, the fuel Heating tail pipe links to each other with the high pressure oil pump that has return tube, the fuel oil temperature measuring equipment is installed on fuel Heating tail pipe or high pressure oil pump, the oil return control valve is installed on return tube.
When the utility model uses, can in time understand fuel oil temperature by the fuel oil temperature measuring equipment that is installed on fuel Heating pipe or the high pressure oil pump, when fuel oil temperature soon reaches setting value, just can fast a part of fuel oil be branched in fuel tank or the fuel oil filter by the oil return control valve of opening installation on return tube, thereby can be to controlling through the fuel oil temperature of fuel-firing preheating device preheating, reduce fuel oil temperature, prevent the too high phenomenon of fuel-firing preheating temperature, guarantee the internal-combustion engine proper functioning.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment 1 a linkage structure schematic representation;
Fig. 2 is the utility model embodiment 2 a linkage structure schematic representation;
Fig. 3 is the utility model embodiment 3 a linkage structure schematic representation;
Fig. 4 is the utility model embodiment 4 a linkage structure schematic representation.
Embodiment
A kind of improved fuel of internal combustion engine preheating temperature control gear, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, comprise fuel tank 3, fuel-firing preheating device 10 and the fuel Heating tail pipe that from fuel-firing preheating device 10, passes, the fuel Heating tail pipe links to each other with the high pressure oil pump 11 that has return tube 2, return tube 2 can link to each other with fuel tank 3, also can directly link to each other with fuel oil filter.On fuel Heating tail pipe or high pressure oil pump 11, fuel oil temperature measuring equipment 12 is installed, oil return control valve 1 is installed on return tube 2.Said oil return control valve 1 is automatically controlled Flow valve or upgrading valve or manually-operated gate or solenoid valve.Automatically controlled Flow valve can be single, double loop-type electronic current metered valve or electromagnetic flow valve.As shown in Figure 4, in order to improve control ability, correspondent control circuits plate 8 is installed on the circuit of automatically controlled Flow valve to automatically controlled Flow valve.
Said fuel oil temperature measuring equipment 12 is a thermometer, and when the fuel oil temperature of thermometer demonstration soon arrived the temperature warning value, rotating switch 5 can make automatically controlled Flow valve action, helps reducing manufacture cost of the present utility model like this.
Said fuel oil temperature measuring equipment 12 is temperature transducer or temperature control electronic switch, and temperature transducer or temperature control electronic switch are electrically connected with said automatically controlled Flow valve by lead.When the fuel oil temperature of temperature transducer perception soon arrived the temperature warning value, temperature transducer just can order about automatically controlled Flow valve action automatically, thereby improves automatic control level of the present utility model.
Obviously,, adopt the recirculating oil quantity of manually-operated gate control return tube, also be fine in order to reduce production costs.
As shown in Figure 4, fuel oil filter 9 is installed on the fuel Heating tail pipe,, improves the fuel oil degree of purity in order to fuel oil is filtered.
