TITLE: A SYSTEM AND METHOD FOR AUTOMATIC IGNITION CUT-OFF OF A VEHICLE ENGINE 5 FIELD OF DISCLOSURE The present disclosure relates to automobiles. Particularly, the present disclosure relates to monitoring the activities of a 0 vehicle engine and altering the throughput to the engine depending upon the monitored activities. DEFINITIONS 5 The expression "vehicle" used in the context of this disclosure refers to but is not limited to automobiles, motorcycles, cars, jeeps, trucks, two wheeler vehicles, three wheeler vehicles, four wheeler vehicles, multi-wheeled vehicles, and the like. 0 This definition is in addition to those expressed in the art. BACKGROUND 25 Vehicles are typically driven in two modes namely engine-off mode and engine on mode. In the engine-off mode power is not supplied to the vehicle from the engine, while in engine on-mode a vehicle derives power for its operations from the engine. The term idle RPM/idle speed is used to refer to the rotational speed 30 of the engine when the engine of a vehicle is not coupled to the drive train or transmission of the vehicle and throttle control such as throttle pedal or grip is not actuated.
At idle RPM, the engine generates enough power to facilitate working of its ancillaries such as coolant pump, power steering, air conditioner and the like. However the speed and power generated at the idling RPM of an engine is not 5 sufficient to bring about movement of the vehicle. Therefore, the phenomenon of making the engine run at an idling RPM results in unnecessary fuel consumption without utilization of productive engine power. Keeping the engine running at idling RPM also results in generation of exhaust/combustion gases which in turn contribute towards environmental pollution. Further, O keeping the engine running at idling RPM also results in avoidable wear and tear of the parts of the engine in addition to increasing the operational load on the engine. A vehicle engine is stopped from rotating when the vehicle comes to a dead stop 5 and the throttle control is completely closed. Such a phenomenon is typically possible when the vehicle is stopped at a traffic junction or when the vehicle is caught in a traffic jam. Under the aforementioned circumstances drivers keep the engine running at idle RPM resulting in unnecessary consumption of fuel and generation of exhaust gases. 20 However, despite the drawbacks associated with running an engine at idle RPM, most of the drivers prefer keeping the engine running at idle RPM rather than turning the engine off, in order to avoid frequent engine restarts. The phenomenon of keeping the engine running at idle RPM has the following 25 disadvantages: * running the engine at idle RPM does not generate enough power to move the vehicle from standstill; 2 * at idling RPM, the engine consumes fuel but does not produce enough power for gaining momentum, thereby resulting in needless fuel consumption; e the engine releases combustion/exhaust gases even at idling RPM, thereby 5 contributing towards environmental pollution; and * the parts of the engine are subject to wear and tear even at idling RPM. In conventional vehicle engines, the option of shutting the engine off and restarting the same rests solely with the driver. Most of the drivers unknowingly prefer to keep the engine running at idling RPM even when the vehicle is not 0 moving, in order to avoid frequent shut-offs and restarts of the engine even though, keeping the engine running at idling RPM has several disadvantages. Therefore, there is felt a need for a system which overcomes the drawbacks of conventional vehicle engines. 5 OBJECTS Some of the objects of the system of the present disclosure, which at least one 0 embodiment herein satisfies, are as follows: An object of the present disclosure is to provide a system that continuously monitors various activities corresponding to the running of the engine and vehicle. 25 Another object of the present disclosure is to provide a system that automatically suspends the activities of the engine when the engine is running at an idling RPM. 3 Yet another object of the present disclosure is to provide a system that helps to improve fuel economy and increase the mileage of a vehicle.

DETAILED DESCRIPTION OF THE ACCOMPANYING DRAWINGS 0 In conventional vehicle engine, the driver has the option of turning the engine off when a vehicle comes to a standstill. However, as the option of shutting the engine off and restarting the same is at the driver's discretion, most of the drivers prefer to keep the engine running, even when the vehicle is at a 25 standstill, in order to avoid frequent engine restarts. However, keeping the engine running at idle RPM when the vehicle is at a standstill does not produce any productive engine power but results in fuel consumption and also paves the way for release of exhaust gases into the atmosphere. Therefore, in order to overcome the aforementioned limitations, the present disclosure envisages a 30 system that automatically suspends the activities of a vehicle engine when the vehicle comes to a standstill with respect to the surroundings. 8 A system and method for automatic ignition cut off of a vehicle engine of the present disclosure will now be described in detail with reference to the embodiment shown in the accompanying drawings. The embodiment does not 5 limit the scope and ambit of the disclosure. The description relates purely to the examples and preferred embodiment of the disclosed method and its suggested applications. The embodiments herein and the various features and advantageous details 0 thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and 5 to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. The present disclosure envisages a system and method for automatic ignition cut 20 off of an engine of a vehicle and hence causing the vehicle to come to a halt when the engine is running at a predetermined value of idling RPM. FIGURE 1 illustrates a system 100 for automatic ignition cut off of a vehicle engine which suspends the activities of a vehicle engine 10 when the vehicle 25 comes to a standstill. The system 100 includes a sensor module 12, a manual override switch 11 and a restarter 16. The sensor module 12 receives sensed signals from a RPM sensor 13A, a motion sensor 13B, a vehicle angle sensor 13C, a temperature sensor 13D, a battery sensor 13E and a starter mechanism sensor 13F. 9 The RPM sensor 13A senses the RPM (Revolutions per Minute) of a vehicle engine 10. In the event that the RPM of the vehicle engine 10 falls below a pre determined level/reaches idling RPM, the RPM sensor 13A generates a digital 5 trigger to be sent to the sensor module 12. Typically, the idling RPM for four wheelers is in the range of 600-700 and for two wheelers is in the range of 1000-1500. The pre determined range is programmable depending on the requirements of the vehicle engine or vehicle manufacturer. The system 100, after a pre determined time interval, typically '5' seconds, subsequent to 0 receiving the trigger from sensor module 12, suspends the activities of the vehicle engine 10 by cutting off the ignition. The system 100 includes a timer/counter 12A for determining the pre determined time interval subsequent to receiving the trigger from the sensor module 12. 5 The motion sensor 13B enables sensing whether the vehicle has travelled a pre determined distance, typically '100' meters (in), on turning ON the ignition key or on restarting the engine after every automatic stop. The predetermined distance is calibrated/programmed by the vehicle engine or vehicle manufacturer depending on the requirements. 20 Further, the motion sensor 13B enables detecting whether the vehicle is in motion and transmits a signal to the system 100 through the sensor module 12. The ignition of the engine is cut off when the motion sensor 13B detects that the vehicle is not in motion. The motion sensor 13B is, typically, an accelerometer 25 or a micro electro-mechanical (MEMS) based system. Further, the system 100 shuts down the vehicle engine 10 when the vehicle angle sensor 13C is not in an ON condition or the vehicle angle direction is more than a predetermined angle value, typically 80, and a temperature sensor 13D detects an engine temperature which is more than a predetermined engine temperature, typically 40 0 C. 10 Alternatively, another parameter monitored by the sensor module is a pre determined time of running the vehicle above a pre-determined speed; the threshold values for pre-determined time being 1 minute and the predetermined speed being 25km/h. 5 In accordance with the present disclosure, the sensor module 12 will not transmit a signal instructing the system 100 to suspend the activities of the engine 10 in the event that the vehicle speed and the engine RPM is above a threshold value. 0 The sensor module 12 does not transmit a signal to the system 100 for suspending the activities of the vehicle engine 10 and enables maintaining the activities of the vehicle engine 10, in the event that the battery sensor 13E detects that the battery (not shown in figure) is either not present or out of 5 charge or the output provided by the battery at a particular time is less than a predetermined voltage, typically 13 volts. Thus, the system 100 enables maintaining the minimum battery voltage required to start the vehicle engine 10, typically 13 volts, as the system 100 is unable to restart the vehicle engine 10 subsequent to ignition cut-off when the battery voltage is lower than 13 volts. 20 The battery sensor 13E is also configured to detect the physical presence of the battery by electrical connections of the battery. If the battery is not physically present, the system 100 does not suspend the activities of the vehicle engine 10. Further, the system 100 enables detection of faulty starting mechanism by 25 means of the starter mechanism sensor 13F communicating with the sensor module 12. The sensor module comprises a typical current sensor which senses the starting current every time the vehicle is started. This is compared against a threshold value and if this starting current exceeds the threshold value, the automatic engine shut off shall not be enabled, even though the other 11 aforementioned conditions are met for shutting off the engine. This enables suspending the activities of the vehicle engine 10 in the event that a faulty vehicle starting mechanism is detected by the starter mechanism sensor 13F even if all the conditions for restarting the activities of the vehicle engine 10 are 5 met. The system 100 further includes an indicator 14 communicating with the sensor module 12 in order to issue/display an audio based indication and/or a video based indication or both before the activities of the vehicle engine 10 are to be 0 suspended. The system 100 of the present disclosure is not limited to the use of audio/video indication alone and can be implemented using other indicating means known in the art. A manual override switch 11 is provided on the system 100. The manual 5 override switch 11 is accessible to drivers of the vehicle and is configured to manually prevent the system 100 from automatically suspending the activities of the vehicle engine 10. The system 100 further includes a restarter 16 to transmit a digital trigger to the 20 system 100, subsequent to suspension of the activities of the vehicle engine 10, in order to re-activate the vehicle engine 10. The restarter 16 enables determining whether the vehicle engine 10 is in a suspended state and restarting the vehicle engine 10 if the vehicle engine 10 is detected to be in a suspended state. The restarter 16 enables restarting the vehicle engine 10 on initiating 25 actuation of an accelerator, pressing a start button, pressing at least one brake lever or cranking the engine by ignition key switch. The shutting of the vehicle engine 10 and hence stopping of the vehicle is achieved by preventing the vehicle engine 10 from sustaining piston oscillations 12 by advancing the ignition timing with respect to the top dead center (TDC) of vehicle engine 10 from the value meant for normal operation of the engine. The system 100 is either integrated within the ignition system of the vehicle or is provided as a discrete control module cooperating with the vehicle. 5 The system 100 enables maintaining the tail lamp in ON configuration while the vehicle is not in motion and the ignition is cut-off by the system 100. The tail lamp is maintained in ON configuration when the tail lamp switch is in ON condition. Thus, the system 100 enables increasing the safety of the vehicle 0 when the vehicle is stopped in a low lighting condition. In accordance with the present disclosure, the system 100 can be an add-on module which could be integrated within the engine of vehicles. Alternatively the system 100 can also be developed as a part of the ignition system of 5 vehicles. FIGURE 2 is a flowchart illustrating the steps corresponding to the method of operation of the automatic ignition cut off of the vehicle engine. The method, in accordance with the present disclosure includes the following steps: 20 e determining whether an ignition switch of the vehicle engine is in 'ON/OFF' state; e detecting physical battery presence, start input, and position of an override switch upon the ignition switch being in 'ON' state; e detecting the starting mechanism of the vehicle engine; 25 e starting a counter upon detecting vehicle motion and counting up to a pre determined distance travelled by the vehicle; e determining whether the output of a vehicle battery is within a pre determined threshold range; 13 * maintaining the activities of the vehicle engine upon determining that the power of the vehicle battery is within the pre-determined threshold range; e checking parameters associated with the vehicle engine including the RPM of the vehicle engine, temperature of the vehicle engine and vehicle 5 direction angle motion upon determining that the output of the vehicle battery is within the pre-determined threshold range; * waiting until the expiry of a pre-determined time duration and enabling at least one of an audio alarm and a video alarm; e suspending the activities of the vehicle engine by way of ignition cut-off 0 on the occurrence of at least one event selected from the group consisting of, faulty starting mechanism of the vehicle engine through starting current, the RPM of the vehicle engine reaching an idling RPM value, temperature of the vehicle engine rising above a pre-determined threshold value and vehicle direction angle being more than a pre-determined 5 threshold level; e detecting a restarting action by a driver of the vehicle; and * re-activating the vehicle engine in the event of any restarting action by the driver. 20 The system and method for automatic engine cut-off of a vehicle engine of the present disclosure can be seamlessly integrated with a wide variety of vehicle engine types. The system can be an add-on module which could be integrated within the engine of vehicles. Alternatively the system can also be developed as a part of the ignition system of vehicles. Additionally, the system as explained 25 above can also have threshold values programmable to suit specific vehicle and / or engine parameter thresholds. 14 TECHNICAL ADVANCEMENTS AND ECONOMIC SIGNIFICANCE The technical advancements offered by the present disclosure include the realization of: 5 e providing a system that continuously monitors various activities corresponding to the running of the engine and vehicle; e providing a system that determines whether a vehicle engine is running at an idling RPM; 0 e providing a system that automatically suspends the activities of the engine when it is determined that the engine is running at an idling RPM; e providing a system that can be customized and programmed to suspend the activities of the engine at any preferred RPM levels; e providing a system that includes a manual override option to prevent the 5 engine from shutting off at idling RPMs; e providing a system that can be seamlessly integrated with vehicle engines of all varieties and types; e providing a system that helps in improving fuel economy and increasing mileage of a vehicle; 20 e providing a system that help in reducing the amount of exhaust/combustion gases released from the exhaust system of a vehicle; e providing a system that reduces the engine run-time; and * providing a system that helps to increase the life of the engine. 25 Throughout this specification the word "comprise", or variations such as "ccomprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. 15 The use of the expression "at least" or "at least one" suggests the use of one or more elements or ingredients or quantities, as the use may be in the embodiment of the disclosure to achieve one or more of the desired objects or results. 5 The numerical values given of various physical parameters, dimensions and quantities are only approximate values and it is envisaged that the values higher or lower than the numerical value assigned to the physical parameters, dimensions and quantities fall within the scope of the disclosure unless there is a statement in 0 the specification to the contrary.
