Description:A SYSTEM AND METHOD FOR IMPROVING LUBRICATION SYSTEM AND ENGINE PERFORMANCE
FIELD OF INVENTION
[0001] The present invention relates generally to engines and more particularly to a system and method for improving lubrication system and engine performance of LPG fuel engines.
BACKGROUND
[001] Recently, on account of the high price of petrol and diesel, the continuously increasing rate of pollution in particular in large urban areas, and the resonance that environmental problems caused by pollution are raising, there is an increasingly frequent demand for automobiles, including brand new ones, to have the possibility of being fuelled not only by petrol/diesel also by LPG. Utilization of LPG as a fuel for internal combustion engines has been heretofore been known for use in large internal combustion engine powered arrangements such as forklifts, trucks, buses and other such arrangements and devices.

[002] In general, the internal-combustion outboard motors are of the petrol or diesel fuelling type. Anyway, many models also fuelled with LPG have been introduced onto the market since many years and an increasing numbers of petrol fuelled motors are modified specifically to run on a bi-fuelling LPG/petrol system. Liquid gas engines differ from petrol/diesel engines in the different mixture preparation which is necessitated by the great tendency of liquid gas to evaporate. Liquid gas is supplied, as a liquid under pressure, to the engine in corresponding delivery lines. In an evaporator, the liquid gas is converted into the gaseous state by the supply of heat. The evaporator is a heat exchanger, to which heated cooling water is supplied in order to heat and evaporate the liquid gas. The evaporator is combined with a pressure regulator, in order to keep the then gaseous liquid gas within a specific pressure range. The liquid gas is then supplied to a gas/air mixer which mixes liquid gas with air. In present design lubrication pipe is connected to the mixer unit.

[003] Over the period many LPG fuelling system/kits have been developed for various engines such as automobile engines, outboard motors and other marine engines etc. to run on LPG as fuel. At present, particularly in two stroke outboard engine lubrication oil is mixing with petrol / kerosene fuel while running outboard engine on petrol / kerosene.

[004] However, said two Stroke outboard engine required separate oil supply system to run engine on LPG fuel. In existing LPG system, lubrication oil supply given to the two stroke engine through Gas air mixer unit or through carburettor as preferably in present design lubrication pipe is connected to the mixer unit.

[005] During outboard engine or other engine cranking / operating condition, engine creates suction / vacuum at Gas air mixer unit which is fitted on intake of carburettor assembly. Due to vacuum / suction at Gas air mixer unit, lubrication oil and gas is supplied to engine through carburettor intake system as in present design lubrication pipe is connected to the mixer unit.

[006] However, it has been observed that, particularly during outboard engine in idle condition and /or reverse gear operating condition there is a very less or negligible vacuum available at mixer unit which is fitted on intake of carburettor. Due to very less vacuum, very less/ no flow of lubrication oil supply to outboard engine running in idle and/or reverse gear operating condition has been observed. Hence it has an effect on engine performance due to less or no lubrication oil supply. Also, there are chances of engine seize / stall.

[007] For the reasons stated above, which will become apparent to those skilled in the art upon reading and understanding the specification, there is a need in the art for a system and method thereof that is improving lubrication system and engine performance of LPG fuel engines and is useable, scalable and independent of complicated technological mechanism and is portable and can be deployed anywhere in very little time.

[0027] According to one of the embodiments of a system and method of the present invention a Vacuum Plate, is provided for improvement in lubrication system to overcome the inconsistency in the performance of lubrication system and engine. The vacuum plate of the present invention is fitted on intake manifold after carburetor to improve lubrication system which also improved engine performance. According to the system and method of the present invention the Vacuum plate have at least two vacuum nozzles, one of which is connected to the vacuum operated oil pump through vacuum hose and the outlet of vacuum operated lubrication pump is connected to the other vacuum nozzle of the Vacuum plate. The vacuum plate is easily fitted on engine after intake manifold without any modifications in carburetor and intake manifold. There is no need of specially skilled person to fix the Vacuum plate on engine after intake manifold. Also, by incorporating vacuum plate performance of outboard engine is improved due to proper functioning of vacuum circuit.

[0028] The Figure 1 illustrates a sectional view of the LPG fuelled engine system according to one of the prior art. According to the prior art, at present, particularly in 2-stroke Outboard Marine engines running on Petrol/Petrol start Kerosene run, the lubrication oil is mixed in Petrol/Kerosene. As such Petrol + lubrication oil or Kerosene + lubrication oil enters through the carburettor to the engine. However, when this 2 stroke outboard engine is connected to run on LPG, liquid lubrication oil can not be mixed in LPG cylinder. As such separate lubrication system is required. In the prior art lubrication oil as well as LPG is supplied to the mixer simultaneously and vacuum is sensed from the carburettor and is given to the lubrication vacuum pump as well as regulator. In this case it has been observed that the vacuum of the carburettor is not very sensitive, and is affecting the oil supply as well as LPG supply to the engine. Particularly when the outboard engine is in idle condition and/or reverse gear operating condition there is very less or negligible vacuum is available at carburettor. Due to very less vacuum, very less/no flow of lubrication oil supply has been observed to outboard engine running in idle and /or reverse gear operating condition and engine starves for lubrication oil supply which may lead to the engine seize and complete damage to the engine.

[0029] Figure 2 illustrates a schematic diagram of system and method thereof for improving lubrication system and engine performance of LPG fuel engines according to an exemplary implementation of one of the embodiments of the present invention. As illustrated in the figure 2 the system and method thereof of the present invention comprises at least one engine (109), at least one carburettor (114), at least one LPG kit (100) comprising at least one LPG Cylinder (101), at least one Liquid LPG withdrawal valve (102), at least one Dip Tube (103), at least one Adaptor (104), at least one improved LPG regulator cum vaporizer (105), at least one gas-air mixture unit (108), at least one vacuum hose engine to regulator (112), at least one vacuum diaphragm (403), at least one improved spring (404), at least one lever (405); and at least one vacuum plate (130), the vacuum plate (130) fixed on engine (109) between the carburetor (114) and an intake manifold (141) of engine (109)

[0030] According to one of the embodiments of a system and method of the present invention after incorporating vacuum plate in outboard LPG kit, when outboard engine is running in idle and /or reverse gear operating condition there is a sufficient engine vacuum is available at the vacuum plate as it is fitted between carburetor and engine manifold. It helps to have sufficient vacuum available at both lubrication oil nozzle and vacuum nozzle on vacuum plate. The vacuum nozzle on vacuum plate is connected to the vacuum operated oil valve and same vacuum taken for Improved LPG regulator cum Vaporizer through vacuum hose. The outlet of vacuum operated oil valve is connected to the lubrication oil nozzle on vacuum plate. As sufficient vacuum is acting on the vacuum operated oil valve as well as LPG regulator cum vaporizer it helps to give required quantity of oil to the engine as well as improves performance of Improved LPG regulator cum Vaporizer even in idle and /or reverse gear operating condition

According to the present invention the vacuum plate to improve lubrication system and engine performance of LPG fuel engines is fitted in between engine intake manifold and carburettor.

[0032] According to one of the embodiments of the present invention a vacuum plate can be easily fixed on engine between carburetor and intake manifold of engine without any modifications in carburetor and intake manifold. Due to sufficient vacuum at vacuum nozzle on vacuum plate, improved regulator cum vaporizer is also working properly and giving better engine performance on LPG fuel.

[0033] According to one of the embodiments of the present invention once the outboard engine is cranked / started, vacuum develops in intake system of outboard engine. The Vacuum plate is fixed on engine on intake manifold in intake system of outboard engine. Hence vacuum is already available at vacuum plate and nozzle and same is connected to LPG regulator and vacuum operated oil pump through vacuum hoses resulting very consistent performance of the lubrication system as well as the performance of outboard engine.
