Abstract
The utility model discloses an engine protection device based on a turbine rear exhaust temperature. According to the utility model, the temperature signal of an exhaust port is acquired through a temperature sensor, and then transmitted to a vehicle-mounted ECU (Electronic Control Unit) module; the by the vehicle-mounted ECU module compares an acquired actual temperature value acquired with a reference temperature value set in the internal logic program of the vehicle-mounted ECU module, if the actual temperature is higher than the reference temperature, the vehicle-mounted ECU module sends a control signal to an engine fuel injector for reducing the fuel charge of an engine fuel injector so as to achieve the effect of limiting an engine torque, thus the engine turbine rear exhaust temperature is measured after the whole automobile assembly is finished, adverse influences on the normal working of an engine and other related components of a motor vehicle power system due to over-high engine turbine rear exhaust temperature are avoided, the working reliability of the engine is correspondingly improved, and the service life is correspondingly prolonged.
Description
Technical field
The utility model relates to Motor Vehicle power system auxiliary accessories technical field, particularly a kind of engine protection device based on turbine final vacuum temperature.
Background technique
In existing Motor Vehicle process of manufacture; Its engine turbine final vacuum temperature is a very important performance parameter; If this engine turbine final vacuum temperature is too high, then can the proper functioning and the usability of other associated components of motor and Motor Vehicle power system be had a negative impact.
The mensuration process of present existing motor car engine turbine final vacuum temperature; Usually be only limited in the engine pedestal calibration process before the car load assembling and carry out; And after Engine Matching car load and car load assembling completion, engine turbine final vacuum temperature is not carried out related assays work.Though this kind method can satisfy the basic need of Motor Vehicle production and processing; But owing to can cause certain influence to the service behaviour and the relevant parameter thereof of motor in the associated components working procedure after the car load assembling completion; The too high phenomenon of engine turbine final vacuum temperature still can appear in the motor-driven vehicle going process; Thereby the functional reliability to motor causes adverse effect, and then brings hidden danger for the cruising of Motor Vehicle.
Therefore, how after the car load assembling is accomplished, engine turbine final vacuum temperature being measured is the important technological problems that those skilled in the art need solve at present.
The model utility content
The purpose of the utility model provides a kind of engine protection device based on turbine final vacuum temperature, and this engine protection device device can be measured engine turbine final vacuum temperature after the car load assembling is accomplished.
For solving the problems of the technologies described above; The utility model provides a kind of engine protection device based on turbine final vacuum temperature; The temperature transducer that comprises the exhaust ports that is arranged at engine supercharger; And the vehicle-mounted ECU module that matches with said temperature transducer, and said vehicle-mounted ECU module matches with engine fuel injector.
Preferably, said TEMP implement body is arranged on the vent connection of engine supercharger.
Above-mentioned background is technological relatively; The engine protection device that the utility model provided based on turbine final vacuum temperature; The temperature transducer that comprises the exhaust ports that is arranged at engine supercharger; And the vehicle-mounted ECU module that matches with said temperature transducer, and said vehicle-mounted ECU module matches with engine fuel injector.In the working procedure; Gather the temperature signal of said exhaust ports through said temperature transducer; And the temperature signal that collects is passed to said vehicle-mounted ECU module place; By said vehicle-mounted ECU module the reference temperature value of setting in the actual temperature value of being gathered and its internal logic program is compared, if true temperature is higher than reference temperature, then said vehicle-mounted ECU module is sent control signal to engine fuel injector; Reduce the fuel injection quantity of said engine fuel injector; Reaching the limiting engine effect of torque, thus realized the car load assembling accomplish after to the mensuration of engine turbine final vacuum temperature, avoided because of the too high adverse effect that the proper functioning of motor and other associated components of Motor Vehicle power system is caused of engine turbine final vacuum temperature; And make the corresponding raising of functional reliability of motor, corresponding prolongation in its working life.
In another preferred version of the utility model, said TEMP implement body is arranged on the vent connection of engine supercharger.This temperature transducer is arranged on the said vent connection; Can guarantee that said temperature transducer fully contacts with the engine turbine final vacuum; The actual exhaust air temperature that guarantees said temperature sensor measurement more accurately and reliably, thereby make the whole using effect of said engine protection device be able to corresponding raising.
