A SYSYEM AND A METHOD TO HYBRIDIZE AN ENGINE AND A VEHICLE THEREOF
FIELD OF THE INVENTION
The present invention relates to a method to assist engine, a system implementing the said method to assist engine, an engine having such system and a vehicle having such engine. Specifically, the present invention relates to method and system assisting the engine to provide necessary power when required and thereby reduce fuel consumption and improve efficiency. Also prevent engine stalling.
BACKGROUND OF THE INVENTION
Generally hybrid vehicles having an IC engine and an electric motor generator, for mobility of the vehicle. The IC engine energised by fossil fuels, provides power for mobility of the vehicle. The electric motor generator driven by a battery, supplies power only when there is requirement for supplementary power.
In a vehicle having mechanical system, at higher load on engine more fuel will be consumed. The fuel efficiency of the vehicle is reduced. During air-conditioning the vehicle, a part of engine's energy is utilised. Therefore, the vehicle does not perform as expected.
In starting the engine of the a vehicle having mechanical system, a starter motor to crank the engine consumes large amount of energy from the battery. This leads to lower battery life.
In agricultural vehicle having mechanical fluid injection pump, the power requirement surges when there is an implement coupled and operated by the agricultural vehicle. During agricultural vehicle's implement operation on the field, there exists variations in engine RPM transmitted to the gear box, engine stalling, wheel slip and low efficiency, because a part of energy from engine is supplied to the implement coupled to the agricultural vehicle for its operation. This phenomena reduces the farming efficiency of the agricultural vehicle.

The additional energy can be provided to the engine by electrification of engine. The electrification is carried out by providing additional required energy to the engine by means of an electric motor-generator. Based on the engine operating parameters, the additional energy is supplied to the engine. The Engine control unit provide the necessary signals to the battery control unit, for appropriate supply of additional energy to the engine.
Furthermore, in the existing vehicle installing engine control unit and optimising the vehicle accordingly is tedious job and also a costly affair. Therefore, a means for electrification of engine to provide additional energy to engine as require for its operation, having no engine operating parameters to control the electrification, is required for better efficiency and operation of the vehicles.
US Patent 8776929 discloses a hybrid power system for a vehicle having an internal combustion engine and a supplemental energy system for converting the mechanical energy generated by the engine to electrical energy and storing it and using the stored electrical energy to augment engine output as necessary. Furthermore, the hybrid system can be installed in the existing vehicles. But, the present system utilises the engine parameter as well the other parameters for electrification of engine.
US Patent 9776615 discloses a hybrid work vehicle capable of smooth work travel using a work device with a low output internal combustion engine, while avoiding battery exhaustion. The vehicle having an internal combustion engine that supplies drive power to a travel device and a work device via power transmission means, a motor generator that is driven by a battery, a load information generation part that generates load information representing a sudden increase in rotational load, an assist characteristic determination part that determines motor assist characteristics defining an assist amount and an assist time period of assist control based on load information, and a motor control unit that controls the motor generator based on the motor assist characteristics. The disclosed hybrid system cannot be used in the existing vehicle. Furthermore, the present invention utilises the engine parameters to provide additional energy to the vehicle's engine.

Therefore, in view of above, there is need in art to provide a system to provide additional energy to the engine as and when required, to improve the working efficiency, fuel efficiency, wheel slip and prevent engine stalling.

f) controlling appropriately the converter unit, on the basis of estimated required additional energy, to supply energy between the battery unit and the motor generator unit; and,
g) providing mechanical energy from the motor generator unit (103) to the engine (101) or the engine (101) to the motor generator unit (103) through the power transmitting unit (102).

32) A method to hybridize an engine as claimed in claim 31, additionally measuring implement draft by a ninth sensor (107) and transmitting a signal from the said ninth sensor (107) to the control unit (106).
33) A method to hybridize an engine as claimed in claim 31 and claim 32, wherein the engine (101) is cranked upon switching the ignition switch on, by means of the motor generator unit (103) through the power transmitting unit (102).
