The present disclosure relates generally to a field of an assembly for regulating lubrication fluid flow to an engine rocker arm. More specifically, it pertains to a cost-effective assembly which enables regulated lubrication fluid flow at close position of an engine valve and disables lubrication fluid flow at open position of the engine valve. The assembly disables lubrication fluid into combustion chamber of engine through engine valve, thereby minimizing Particulate Matter (PM) level in engine emissions.
BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [0003] An inlet valve and exhaust valve of an engine valve is operatively configured with a rocker arm. The rocker arm is operatively coupled with a plunger member such that movement of the plunger member (can be referred to as push rod, herein) enables movement of the rocker arm. The plunger member is coupled with a tappet, which in turn is configured with a camshaft such that the tappet converts rotary motion of the camshaft into reciprocating motion. The camshaft is configured with the crankshaft via timing gear train. Sequencing and timing of the tappet reciprocating movement is achieved by rotational motion of cam profile of the camshaft. Tappet starts reciprocating movement when the corresponding cam profile on the camshaft engages with the tappet. Reciprocating movement of the tappet is then transferred to the plunger member and in turn from the plunger member to the rocker arm. The rocker arm is adapted to allow movement of the inlet valve or the exhaust valve thereby enabling opening and closing of inlet valve or exhaust valve.
[0004] Various components described above namely camshaft, tappet, plunger member, and rocker arm are in continuous movement, either rotary or linear, and

hence require proper lubrication. The engine lubrication system enables lubrication fluid flow from the tappet to the rocker arm through plunger member. The tappet is fluidically coupled with the lubrication passage in the engine which ensures continuous flow of lubrication fluid to the tappet.
[0005] Lubrication fluid from the tappet flows into rocker arm through plunger member under pressure and this flow, if not controlled, can allow entry of lubrication fluid into combustion chamber before closing of respective inlet valve or exhaust valve. Normally, the flow of lubrication fluid from the tappet to the plunger member is collinear. The plunger member is configured with first aperture and second aperture. The first aperture is in-line with the second aperture which enables fluid flow from the tappet to the rocker arm through plunger member without any regulation. Thus, the continuous flow of lubrication fluid to the rocker arm lets entry of lubrication fluid into engine combustion chamber through inlet valve, inlet valve guide, inlet valve seat, clearance between inlet valve and inlet valve guide, or exhaust valve, exhaust valve guide, exhaust valve seat, and clearance between exhaust valve and exhaust valve guide.
[0006] As lubrication fluid goes into combustion chamber of an engine, its
burning results in higher levels of particulate matter (PM) pollutants in the emissions. The high levels of particulate matter (PM) in emissions can cause severe negative effects on environment as well as act as health hazard for living beings. Therefore, in successive emission norms, as prescribed by statutory authority, the levels of PM are continually reduced. Hence, compliance to statutory emission norms makes it imperative to arrest entry of lubrication fluid into combustion chamber of the engine.
[0007] In an existing technology, clearance provided between the engine valve (inlet or exhaust) and valve-guide is reduced to minimize entry of lubrication oil in the combustion chamber. Disadvantage with existing technology is very high machining cost for minutely controlling clearance between the engine valve and valve-guide, and also cumbersome machining process. Another disadvantage is that

scuffing problem in valve stem may arise due to reduction in clearance between the engine valve (inlet or exhaust) and valve-guide.
[0008] In another existing technology, a metering device is configured with the plunger member such that lubrication flow can be controlled. Disadvantage with the existing technology is that during an open position of the engine valve, the metering disc allows lubrication fluid flow to the rocker arm through the plunger member. Besides higher cost, this existing technology also increases probability of the lubrication fluid entering into the combustion chamber of the engine, which is undesirable.
[0009] There is, therefore, a need in the art to provide a simple and cost effective device for regulating flow of lubrication fluid from tappet to rocker arm through plunger member such that entry of the lubrication fluid into combustion chamber of engine is arrested during opening and closing of the engine valve, thereby decreasing levels of PM in engine emission.

lubrication fluid can be selected from group including lubricating oil, friction oil, engine lubrication oil, and the likes. In preferred embodiment, the lubrication fluid can be selected as lubricating oil. The lubrication fluid can enter into the vertical passage 212, which can be configured within the cavity 208. When the engine valve 112 is in the close position, the regulating member 202 can be positioned proximal to the surface member 210 of the cavity 208 to form the fluid pathway 206. The lubrication fluid can enter into the fluid pathway 206, which can be configured between the lower member 308 of the regulating member 208 and the surface member 210 of the cavity 208. The lubrication fluid can enter into the fluid track 204 from the second opening 304 through the fluid pathway 206. The fluid track 204 can regulate pressure and flow rate of the lubrication fluid flowing from the second opening 304 to the first opening 302. The optimized lubrication fluid can enter into the plunger member 108 through the first opening 302. The optimized lubrication fluid can enter into the rocker arm 110 of the engine for lubricating various parts of the rocker arm 110. Due to closed position of the engine valve 112 and regulated flow of the lubrication fluid, entry of the lubrication fluid into the combustion chamber of the engine is prohibited.
[0080] In an exemplary embodiment, when the engine valve 112 can be in the open position, the regulating member 202 can move towards the surface member 210 of the cavity 208, such that the regulating member 202 can be in contact with the surface member 210 of the cavity 208, thereby closing the fluid pathway 206. This disables entry of the lubrication fluid flow from the cavity 208 to the first opening 302. Thus, the open position of the engine valve 112 does not allow lubrication fluid flow from the tappet 106 to the rocker arm 110, thereby preventing entry of the lubrication fluid into the combustion chamber of the engine. [0081] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
