This patent search and analysis report summarizes a granted Indian patent for a device that controls overspeeding of automobiles. The device receives engine speed signals and compares it to a preset maximum speed. If the speed is exceeded, it causes misfires in cylinders to reduce power and below the limit, it restarts fuel supply. The invention allows control of high speeds and improves safety. It can be used with carbureted engines running on alternate fuels like CNG and LPG.

Part-3 : Technical part of patented invention Carbureted engines do not have speed control unit as an integral part of their design as seen in multipoint fuel injection engines and diesel engines. Carbureted engines now find applications with alternate fuels such as CNG and LPG and so their use in public domain is increases day by day. So by this kind of inventions high speed engines and highly offensive driving practice practiced by many city drivers can be controlled. Maximum speed limit and speed control of vehicles become an essential and lifesaving feature. Carbureted engines do not have speed control unit as an integral part of their design as seen in multipoint fuel injection engines and diesel engines. Carbureted engines now find applications with alternate fuels such as CNG and LPG and so their use in public domain is increases day by day. So by this kind of inventions high speed engines and highly offensive driving practice practiced by many city drivers can be controlled. Maximum speed limit and speed control of vehicles become an essential and lifesaving feature. The air and fuel quantity supplied to the engine governs the speed of the engine and that of the vehicle. The butterfly valve operated by the throttle thro? control linkage of the accelator pedal. Air and fuel supply to the engine is controlled by the opening of the butterfly valve. However in a carburetor engine fuel flow is governed by the carburetor which is proportionate to the air flow power produced by the ignition of air and fuel provides speed. It is understood that when the throttle is opened more, increased quantity fuel and air is supplied to the engine resulting in high speed. The engine over speed controller (EOSC) receives the speed signals from the engine as input and compares it with the predetermined maximum speed set point contained in the EOSC unit when the engine speed is less than the set value of maximum speed the unit remains inactive and no output signal is given. However, when the engine speed is equal or more than the set point, another electronic switch is activated such that the ignition system generates misfire in one cylinder to reduce the power generated by the engine momentarily by tending to reduce the engine speed. This control unit is pre-programmed, that the engine speed still is more than the maximum pre-set value, yet another cylinder is triggered to misfire to impart better control over the engine speed. If the engine speed is still more than the maximum pre-set value, the third cylinder is also triggered to misfire in all the three cylinders for better speed control. This misfire is monitored for a pre-determined time which is settable in the unit and if this time exceeds, the engine over speed control unit deactivates an electronic switch to stop the fuel supply to the engine. This is in addition to the misfire in the cylinders and is aimed at positive reduction in engine speed. Once the speed limit is below the pre-set value electronic switch is actuated to restart fuel supply. Simultaneously the misfire switches is deactuated to stop misfire and the engine restores its normal speed. This device may also be attached to Carbureted engines running on bifuels like gasoline and CNG and gasoline and LPG. This patent is about to control over speeding of vehicles with help of new device. The device consists of input and an output units and a programmed speed limit valve. The output is connected to electronic switches which are capable of causing misfire in the cylinders and thereafter deactuating the fuel supply to the engine Limitation of Prior Technology/Art : Specific Problem Solved / Objective of Inventor : Brief about Invention : Key Learning Points : Summary of Invention :

We can integrate engine with Electric Controlling Unit (ECU) which controls the opening and closing of valves. We can integrate engine with Electric Controlling Unit (ECU) which controls the opening and closing of valves. We can also attach eddy current generating circuit on crank shaft, which activates once it crosses speed limit.
