Abstract
An engine oil controller in an engine testing process comprises an engine oil filter support, an oil inlet and an oil outlet, wherein the oil inlet and the oil outlet are formed in the support. The engine oil controller in the engine testing process is characterized in that a heat exchanger is fixedly arranged at a position which is close to the engine oil filter support; two ends of a heat exchanged pipeline inside the heat exchanger are respectively communicated with the oil inlet and the oil outlet in the support; two ends of a heat exchanging pipeline inside the heat exchanger are respectively communicated with a water feeding pipe and a water discharging pipe with electromagnetic valves; an engine oil temperature sensor is arranged on a main engine oil channel of an engine or inside an oil bottom casing; the engine temperature sensor is sequentially connected with a temperature sensor and the electromagnetic valve on the water feeding pipe. The engine oil controller in the engine testing process is simple in structure, low in cost, convenient to maintain, low carbon and environmental friendly and enables the water temperature control accuracy to satisfy a government standard requirement for engine performance tests.
Description
Technical field
The invention belongs to technical field of automobile engine, the oil temperature controller specifically in a kind of engine testing process.
Background technique
As everyone knows, motor all needs through its testing property before dispatching from the factory, and the oil temperature control gear structure of present condition Engine Block Test is very complicated, and machine oil needs to be extracted into external engine and cools.Comprise computer temperature control system, compressed-air supply system, the motor-driven oil pump of 220V, proportional control valve, manual exhaust valve, oil temperature sensor, oil flow rate sensor part form, system reliability is poor, and computer self-inspection often but, needs repeatedly to restart; If pressurized air has impurity, easily block jettron, cause proportional control valve to be often failure to actuate, uncontrollable oil temperature; Oil flow rate sensor is failure to actuate, and causes oil pump to quit work, and test is forced to stop; If engine oil pipe line has gas, need manual exhaust.Impact test is carried out smoothly.Particularly each test all needs to change engine sump tank with technique oil sump, and it is very inconvenient to operate, system cloud gray model and maintenance cost high.
Summary of the invention
The object of this invention is to provide the oil temperature controller in a kind of engine testing process.
The object of the present invention is achieved like this, oil temperature controller in a kind of engine testing process, it includes oil filter seating, and oil inlet hole on bearing and spill port, it is characterized in that: on oil filter seating position, be fixedly installed a heat exchanger, be connected with spill port with the oil inlet hole on bearing respectively by heat exchange pipe two ends in heat exchanger, and heat exchange medium pipeline two ends in heat exchanger are connected respectively with the intake pipe of solenoid valve and waste pipe; On main engine oil duct or in oil sump, be provided with an oil temperature sensor, described oil temperature sensor is connected with the solenoid valve on thermal switch, intake pipe successively.。
The technical solution adopted in the present invention comprises the engine motor oil temperature control system of design micro heat exchanger, oil temperature sensor, solenoid valve, temperature detect switch (TDS) composition.Engine running fluid on opportunity forms self oil cooled system by oil pump, main oil gallery, oil filter, gray iron, needs to force cooling during engine test.This device does not make any change to engine structure, only in oil filter, installs this device additional.Oil filter seating has oil inlet hole and spill port, machine oil enters this device by this oil hole and cools, and gets back to oil filter after cooling by spill port.Engine running, according to oil temperature sensor signal, if engine oil temperature is lower than setting temperature, closed electromagnetic valve, cooling circulating water does not enter heat exchanger, and engine motor oil heats up by conducting self-heating.When cycle of engine heats up higher than setting temperature, temperature detect switch (TDS) sends signal, opens solenoid valve, and heat-shift controls engine oil temperature, thus constant engine oil temperature.
Through inspection, structure of the present invention is simple, and with low cost, easy to maintenance, low-carbon environment-friendly, water temperature control accuracy meets the requirement of engine performance test NBS.
Accompanying drawing explanation
Fig. 1 is structural principle simplified schematic diagram of the present invention.
The symbol description of accompanying drawing major component
1-motor, 2-micro heat exchanger, 3-oil filter seating, 4-oil temperature sensor, 5-temp control switch, 6-solenoid valve, 7-cooling water inlet pipe, 8-cooling water drainage water pipe.
Be described in further detail the present invention by example below in conjunction with accompanying drawing, but following example is only the present invention's example wherein, do not represent the right protection scope that the present invention limits, the scope of the present invention is as the criterion with claims.
Embodiment
example 1
As shown in Figure 1, in figure 1 is motor, 3 is the oil filter seating with oil inlet hole and spill port, a micro heat exchanger 2 is being fixedly installed on oil filter seating 3 position, be connected with spill port with the oil inlet hole on bearing respectively by heat exchange pipe two ends in micro heat exchanger 2, and heat exchange medium pipeline two ends in heat exchanger are connected respectively with the intake pipe 7 of solenoid valve 6 and waste pipe 8; On main engine oil duct or in oil sump, be provided with an oil temperature sensor 4, described oil temperature sensor 4 is connected with the solenoid valve 6 on temp control switch 5, intake pipe successively.
The technical solution used in the present invention: during Engine Block Test, according to the temperature signal of oil temperature sensor 4, temp control switch 5 Controlling solenoid valve 5 is opened, thus controlled cooling model water flow controls engine oil temperature.When engine oil temperature is higher than setting value, solenoid valve is opened, and cooling water enters solenoid valve from intake pipe and enters oil filter seating, micro heat exchanger, is reduced by oil temperature; When oil temperature is lower than setting value, closed electromagnetic valve, oil temperature will raise, thus controller oil temperature.
