Abstract
A method and control unit for predicting plunger return spring failure in an automobile is provided. A method (10) for predicting a failure of a plunger return spring in a motor vehicle and a control unit therefor are disclosed. The method receives sensed information from an output port of the vehicle, the sensed information relating to engine parameters such as engine speed, cam lift, and engine-to-pump ratio. The sensed information is processed by the control unit based on predefined thresholds to determine the likelihood of failure. Based on the determination of the likelihood, an indication is sent to an audible or visual alarm to alert the driver.
Description
Technical Field
The invention relates to a method for predicting failure of a plunger return spring in a vehicle component, and in particular in a fuel injection pump in a vehicle.
Background
Mechanical wear of the components is generally unavoidable and is very critical in the case where one uses the component or the system containing the component regularly. Any wear of a component or sub-parts in a component during use may result in a machine malfunction or sudden shutdown. A sudden or unexpected shutdown of the machine may be harmful to the user. The same applies to vehicles. Any downtime due to the failure of any component in the car may also lead to serious accidents. Component failure may be caused by wear over time. Any technique that predicts wear would be useful.

FIG. 1 illustrates a schematic diagram of a method 10 for predicting plunger return spring failure in a fuel injection pump in an automobile.
Detailed Description
Fig. 1 discloses a method 10 for predicting a plunger return spring failure in an injection pump in an automobile. The method 10 comprises the following steps: a first step 105 of receiving, by an electronic control unit, sensing information from an output port of a vehicle, the sensing information being related to an engine parameter; a second step 110 of processing the received sensing information by the electronic control unit at predefined time intervals to determine fatigue-based failure of a plunger return spring in an injection pump in a car; and a third step 115 of transmitting, by the electronic control unit, a warning to the output device, said warning being related to a failure of a plunger return spring in the injection pump in the car, based on the processing of the received sensing information. In an exemplary arrangement, the electronic control unit may be a telematics unit or any similar unit available in an automobile. The automobile referred to herein may be a passenger vehicle or a commercial vehicle. The engine parameter is at least one of engine speed, cam lift, and engine-to-pump ratio.
An electronic control unit for predicting failure of a plunger return spring in an injection pump in a motor vehicle is adapted to: receiving sensing information from an output port of an automobile, the sensing information being related to an engine parameter; processing the received sensing information at predefined time intervals to determine fatigue-based failure of a plunger return spring in an injection pump in an automobile; and transmitting an alert to an output device based on processing of the received sensory information, the alert relating to a failure of a plunger return spring in an injection pump in the automobile. As described earlier, the engine parameter is at least one of engine speed, cam lift, and engine-to-pump ratio. The output device may be at least one of a display and an alarm.
As described above, parameters such as engine speed, cam lift, and engine-to-pump ratio are acquired by using relevant sensors such as a rotational speed sensor. The parameters are acquired continuously over a period of time or at predefined regular intervals. The processing of the acquired information takes place in the electronic control unit.
The processing of the information further comprises comparing the processing result against a predefined threshold. The warning may be audible or visual and indicates to the driver or owner of the car that the relevant component must be replaced or repaired to avoid any problems with the car.
The calculations are performed accordingly:
number of pump revolutions (spring stroke)(s) = for specific tank (bin)
Total number of revolutions of vehicle travel (spring stroke) (Ts) =
Estimating the fatigue strength of the spring:
probability of failure
Input from telematics:
1. engine speed (erpm) case created at 100 rpm steps up to fly-up speed (fly-up speed)
2. Number of occurrences per rpm bin (a) from telematics input
3. Data acquisition frequency (f)
4. Gear ratio (i) = engine speed/pump speed … … input in telematics
5. Input in cam lobe count (nc)/camshaft … … telematics
6. Designed spring stroke number: ns … … input in telematics.
The prediction method described above has an advantage in that serious problems or accidents due to engine failure in the automobile can be reduced.
It should be understood that the embodiments explained in the above description are only illustrative and do not limit the scope of the present invention. Many such embodiments and other modifications and variations of the embodiments explained in the description are contemplated. The scope of the invention is limited only by the scope of the claims.
