NEW BAFFLE SYSTEM INTEGRAL IN INSPECTION COVER
Field of the Invention:
The present invention is related to such a novel a baffle system integrated inside the inspection cover with the intension to achieve desired result in Blow-by filtration (Oil droplets + Hot gases), wherein the said baffle system is characterized as the breather system, made as an integral part of inspection cover. In order to restrict direct emitting of Blow by in open environment, breather system is required. To achieve desired result in Blow by filtration (Oil droplets + Hot gases), the breather system was made possible as integral part of inspection cover as the design was no longer feasible in rocker cover due to assembly duration and service concerns.
As of the functioning, baffle filters the blow by gases (Oil droplets + Hot gases) and allows only the hot gases to flow to the intake manifold while passing through crankcase ventilation unit in between as secondary filter, which further separates the oil particles and provides the gases to intake manifold whereas the oil collected is passed back to the sump.
Said baffle system integrated inside the inspection cover, as described and illustrated through the enclosed drawings, facilitates several advantages, namely cost effective serviceability, lesser dismantling time duration and easy assembly thereof, leading to cost benefit.
Background and object of the present invention:
Prior to 1963 most vehicle engines vented their vapors and oil deposits to the atmosphere and on the road surfaces wherever vehicle is parked. With the increasing demand for environment safe guard, Positive Crankshaft Ventilation was introduced whereby the crankcase vapors were drawn up into the inlet manifold and, along with the air/fuel mixture, burned up in the combustion chambers. To enable this system to work safely and efficiently the ventilation from the crankcase is controlled via a PCV valve. To avoid upsetting the fuel/air mixture, the PCV valve must regulate the evacuation of these blow-by gases and vapors.
Further if the above is left unchecked over a period of time the PCV system will deteriorate which may result in major engine problems. Hence regular maintenance of the PCV system is essential with some manufacturers recommending the renewal of the PCV valve at every major service interval. The maintenance cost of the above system is very high. Also the total time taken for the assembly of the system and dismantling of the system is very high leading to making the service cost high for the vehicles
In order to restrict direct emitting of Blow by in open environment, breather system is required and a number of breather systems are being used in different kind of combustion engines and automotive vehicles.
The prior patent US4602595A describes an oil separator for separating and collecting lubrication oil contained in blow-by gas of an internal combustion engine. The separator is formed in the cylinder-head cover of the engine and incorporates a porous filter or filters made of foam metal for absorbing oil constituents in the blow-by gas. The filter is vertically arranged so as to make the absorbed oil to fall to the bottom of the separator and to be collected by the oil reservoir for recycling the separated oil to the cylinder.
Another prior art US5450835A discloses an air-oil separator for separating oil droplets entrained in air circulating within a portion of an internal combustion engine, comprising: a housing having an inlet for receiving a stream of air having oil droplets entrained therein, and an outlet for discharging a stream of air; a filtration material disposed within the interior of said housing for separating said oil droplets from said stream of air, and annular chamber means for defined by a frustro-conically shaped wall having an exterior defining a helical flow path within said housing through said filtration material and between said housing inlet and outlet such that said oil droplets become separated from said air stream both by impingement against said filtration material and by centrifugal impingement against inner walls of said housing, and an interior for defining a double-back flow path for said oil-droplet laden air stream.
Another Prior Patent US7047955B2 describes a crankcase emission control device of an internal combustion engine comprises a gas/liquid separator that separates an oil mist from blow-by gases flowing therethrough. A first passage is defined in both a crankcase and a cylinder head to connect an interior of the crankcase to a valve rocker cover chamber defined by the cylinder head. A second passage extends from the valve rocker cover chamber to the gas/liquid separator. A third passage extends from the gas/liquid separator to an intake system of the engine. For reducing the height of the entire construction of the engine, the gas/liquid separator is integrally formed by the cylinder head at a position below intake ports of the cylinder head.
One other prior art JP6341189B2 describes a blow by gas recirculation system, which includes an intake manifold attached to one side of an engine and configured to introduce intake air into a combustion chamber, a cylinder block side of one side of the engine, and a blow-by gas An oil separator configured to perform gas-liquid separation, a blow-by gas outlet of the oil separator, a communication unit configured to communicate with the intake manifold, and the blow-by introduced into the intake manifold through the communication unit A blow-by gas recirculation device comprising a PCV valve configured to adjust a gas flow rate.
Even though the combustion engines are conventionally using various kinds of breather systems, towards achieving desired result in Blow by filtration (Oil droplets + Hot gases), there is still high scope of improvement in the construction and functionality of a breather system towards making them more environment friendly easy in construction/assembly as well as user friendly.
In order to restrict direct emitting of Blow by in open environment, Breather system is required. To achieve desired result in Blow by filtration (Oil droplets + Hot gases), the breather system was made possible as the integral part of inspection cover, as the design was no longer feasible in rocker cover due to assembly duration and service concerns.
Accordingly, the instant invention is an attempt to provide a novel breather system, in the form of baffle system integrated inside the inspection cover.
The prime object of the present invention is to provide a baffle system integrated inside the inspection cover wherein to achieve desired result in Blow by filtration (Oil droplets + Hot gases), said baffle system is made as an integral part of inspection cover, to be used as an effective breather system.
Another object of the invention is to provide a baffle system integrated inside the inspection cover, characterized in its functioning wherein the baffle filter the blow by gases (Oil droplets + Hot gases) and allow only the hot gases to flow to the intake manifold while passing through crankcase ventilation unit in between as secondary filter which further separate the oil particles and provide the gases to intake manifold whereas the oil collected is passed back to the sump.
Another object of the invention is to provide baffle system integrated inside the inspection cover, as described and illustrated through the enclosed drawings, which facilitates several advantages, namely cost effective serviceability, lesser dismantling time duration and easy assembly thereof, leading to cost benefit.

As depicted in the drawings, Figure(s) 1 and Figure(s) 5, mainly represents different views of the Baffle system (1). Figures 2(i) and Figure(s) 4 mainly represents the inner views of the Inspection Cover (2), showing the structural features of the Main Chamber (8) thereof. When the Baffle System (1) gets engaged with the said Inspection Cover (2), the Baffle Chamber (10) and the Top Chamber (7) gets formed within the region of the Main Chamber (8); wherein the Baffle Chamber (10) remains below the said Top Chamber (7). Assembly of said Baffle system (1) and Inspection Cover (2) is shown in Figure(s) 2 (mainly in Figures (2(ii)) and (2(iii)), Figure 3 and Figure 6; wherein various structural and constructional features of the overall assembly of the “Baffle System Integral in Inspection Cover” are so as to indicate the efficacious operational features of the said integration of Baffle system (1) with Inspection Cover (2).
There is Blow-by Inlet 3(a) at the Baffle (1), in the form of vertical perforations on the vertical plate of the Baffle (1), which delivers the unfiltered Blow-by into the Baffle chamber (10). Then there is provision of an Outlet 3(b) for the filtered gases, which is in the form of upper perforations in the horizontal plate of the Baffle (1), which receives the gases and forwards it towards the Top chamber (7), after filtration in the baffle chamber (10).
Towards creating an effective assembly of the Baffle System (1) with the Inspection Cover (2), O-ring (4) and Groove Sealing Ring (5) are employed, alongwith nut-bolts and other such mounting means. O-Rings (4) seal the upper blank chamber, that is the Top Chamber (7). The Top Chamber (7), sealed by O-Rings, also work as break in direct contact of Baffle (1) with the 1st outlet 6(a) to avoid suction of oil into the passage.
Once, the said assembly of the Baffle System (1) with the Inspection Cover (2) is formed, it creates 1st Outlet (6a) for the filtered Blow-by gases (that is filtered hot gases), initiated from the Top Chamber (7) of the Main Chamber (8), within the Inspection Cover (2), wherein the upper perforations (3(b)) of the Baffle (1) delivers the filtered Blow-By gases after 1st stage removal/filtration of the blow by gases (Oil droplets + Hot gases) and removal of oil particles. The Inspection Cover (2) comprises the 2nd or final Outlet 6(b) for the filtered hot gases, which finally releases the filtered hot gases, coming from the 1st Outlet 6(a), towards the intake manifold.

O-Rings (4) seal the upper blank chamber, that is the Top Chamber (7). Chamber (7), sealed by O-Rings, also work as break in direct contact of Baffle (1) with the 1st outlet 6(a) to avoid suction of oil into the passage.
The Main chamber (8) of the Inspection Cover (2) is such a depression like cavity on the main body of the said Inspection Cover (2), preferably in rectangular shape, which is provisioned for accommodating the Baffle (1) within its lower region. Once the perforated box portion of the Baffle (1) is accommodated within the lower region of the Main Chamber (8), they mutually form the Baffle Chamber (10) as well as the Top chamber (7).
The drainage opening (9) is created suitably in the baffle system (1), integrated within the Inspection Cover (2), particularly involving the bottom section of the baffle chamber (10) and lower section of the main chamber (8) of the Inspection Cover (2), through which the filtered oil particles return back to the sump.
The Baffle Chamber (10) is the major Baffle component, formed during the assembly of the Baffle system (1) with the Inspection Cover (2), within which steel wool is filed; wherein said Chamber (10) also comprises outlet 3(a) for filtered Blow By gases, as to the Upper perforations on the horizontal plate of the Baffle (1) and it (10) also comprises the inlet 3(b) as to the vertical perforations for unfiltered blow by gases (Oil droplets + Hot gases).

The Baffle Chamber (10) is filled with the steel wool in order to collect oil particles from the Oil-Blow By mixture (that is (Oil droplets + Hot gases)). Said collected oil, gets drained through the drainage opening (9). Once filtered within the Baffle Chamber (10) and separated from oil therein, the filtered Blow By gases move out from the Baffle Chamber (10) through the upper perforation 3(a) and reach to the Top Chamber (7) for second stage filtration. The final filtered hot gases of the Top Chamber (7) move upward through the 1st Outlet 6(a) towards the final outlet 6(b) of the Inspection Cover (2) and get released to the intake manifold.
Figure 3 illustrate the configuration of various structural components involved in performing the filtration of the Oil-Blow by mixture and release of filtered gases into environment. It also depicts the movement of filtered oil through the drainage outlet (9) of the Baffle Chamber (10) towards the sump. The New design is pretty easy in terms of Assembly, as shown in below image of Figure 4. The Circular O–ring is first assembled in Inspection cover (2). Casting groove (5) is provided in the Inspection cover (2) for said O-ring(s) to sit in.
