Abstract
An automatic engine oil pressure warning device is characterized by comprising a pressure sensor and a pressure display device, wherein the pressure sensor and the pressure display device are connected with each other through an electronic control unit; the pressure sensor is arranged on the main oil passage of an engine; and a set normal working range of the oil pressure of the engine is input into the electronic control unit. The automatic engine oil pressure warning device arranged on a motorbike avoids critical failures caused by poor lubrication to moving elements due to too low oil pressure and reduces the critical failure rate of the engine from the original 5 percent to 2 percent, thereby effectively protecting the engine, avoiding engine body damage and abnormal abrasion of the moving elements, and greatly prolonging the service life of the engine.
Description
Technical field
The utility model relates to a kind of pressure autoalarm, relates in particular to a kind of engine motor oil pressure autoalarm.
Background technique
The lubrication system of motorcycle engine is one of main system that guarantees the motor proper functioning, and lubricant oil can form oil film between each moving element, reduce friction, reduce temperature.But during problems such as, oil pump fault low when the used oil quality of motor, oil duct obstruction, lubrication system can break down, and can produce damage and the inordinate wear of motion component to body.Existing motorcycle engine does not possess automatic warning function, and when motor was in accurate failure phase, the user was not owing to know; Onstream inspection; Continue the operation motorcycle, thus to miss to motor check, chance such as maintenance, can cause motor critical failure to occur usually; Like bent axle, piston locking, engine scuffing, transmission system damage etc.
The model utility content
The purpose of the utility model is to provide a kind of can judge whether the engine operation engine oil pressure normally also sends the engine motor oil pressure autoalarm of alarm signal automatically.
The purpose of the utility model is to realize like this; A kind of engine motor oil pressure autoalarm; It is characterized in that: comprise the pressure transducer and the pressure-display device that connect through electronic control unit; Said pressure transducer is arranged on the main oil duct of motor; Preestablish engine motor oil normal operating pressure scope according to motorcycle operating mode characteristics, input engine motor oil pressure normal range of operation setting value in the said electronic control unit, said pressure-display device can send alarm signal automatically when engine motor oil pressure exceeds said setting value.
Above-mentioned pressure transducer comprises pressure cell and is provided with in the enclosure that voltage input end, voltage output end and grounding end are arranged on the said pressure cell.
For the ease of observing, above-mentioned pressure-display device is installed on the instrument panel.
The utility model utilizes the pressure drag characteristic of pressure transducer; Pressure transducer imports the engine oil pressure signal into electronic control unit; Parameters such as electronic control unit binding engine rotating speed; Automatically judge whether this pressure is in setting value, when force value departed from setting value, electronic control unit can the indicated pressure display unit send alarm signal.When the user finds that pressure-display device is reported to the police, can check, safeguard vehicle, avoid causing each moving element insufficient lubrication to cause motor and critical failure occurs, thereby reach the purpose of effective protection motor owing to engine pressure is low excessively.
The utlity model has following beneficial effect; The utility model is provided with engine motor oil pressure autoalarm on motorcycle; Avoided making motor critical failure rate drop to 2%, effectively protected motor by former 5% owing to engine oil pressure is crossed low each moving element insufficient lubrication initiation critical failure that causes; And avoided body injury and the inordinate wear of motion component, increased substantially the working life of motor.
