2 against its seat and effectively serve to seal the cylinder. The valve system is capable of displaying truly variable valve timing (VVT) by simply controlling rotational speed through the motor. This means that the engine will give maximum output even at RPMs other than its predetermined RPM. Prior Work on Rotary Valve Mechanisms 1. A rotary disc valve inlet system has been previously seen in the Kreidler 6 speed racing engine. Here the rotary valve is connected to the engine crank shaft and is rotating with the engine rpm. The valve uses a slot in its area to allow the inlet mixture to pass through which they refer to as the inter period. 2. Use of rotary valves has also been seen in other systems like the Coated Spherical Valve Rotary System. Several systems use rotary ball valves which although differs from our design as far as the valve type is concerned, however using a similar concept or principle of fuel admission into the combustion chamber. 3. A design partially similar to ours is displayed by the PatRoVa rotary valve. It consists of a pair of vertically arranged oppositely facing fronts of disc valves which work on a similar rotary principle for the admission of fuel and passage of exhaust gases into and from the combustion chamber respectively. Calculations The calculations below are done taking an idling engine speed of 1000 RPM The calculations will be shown below step by step categorically. The following valve timing diagram was used as reference to carry out some of the calculations. Speed of Rotary Valve The crankshaft makes 1000 Revolutions in 1 minute The crankshaft makes 1000 Revolutions in 60 seconds Therefore, the crankshaft makes 2 Revolutions in T=120/1000=0.12 seconds i.e. the crankshaft completes 1 full combustion cycle in 0.12 seconds Now, for a rotary disc valve, the valve has to complete one cycle in 0.12 seconds i.e. the rotary disc has to complete 1 Revolution in 0.12 s Therefore, the required speed of the disc = 500 RPM Time spent during the intake stroke The crankshaft rotates for 235 out of the full 720 it rotates in 0.12 s Therefore, the time spent during the intake stroke = (235/720)*0.12 = s Time spent during the exhaust stroke The crankshaft rotates for 225 out of the full 720 it rotates in 0.12 s Therefore, the time spent during the intake stroke = (225/720)*0.12 = s Time Spent during the Compression and Expansion The crankshaft rotates for 290 out of the full 720 it rotates in 0.12 s Therefore, the time spent during the compression and expansion stroke = (290/720)*0.12 = s Time of overlap between initialization of the intake stroke and completion of the exhaust stroke The crankshaft rotates for 30 out of the full 720 it rotates in 0.12 s.therefore, the time spent during the mentioned overlap = (30/720)*0.12 = s Dimensions of Inlet and Exhaust Slots on the engine lining The rotary valve comprises 360 which represents one combustion cycle. The crankshaft rotates 720 through one complete combustion cycle i.e. twice that rotated by the rotary valve essentially meaning that every angle represented on the rotary valve for any stroke is half of the angle through which the crankshaft rotates for the same stroke. Thus, slot angle for the intake stroke = 235/2 = Similarly, slot angle for the exhaust stroke = 225/2 = Similarly, slot angle for the compression and expansion stroke = 290/2 = 145 Similarly, slot angle represented for the valve overlap = 30/2 = 15 Hardware Design The basic design of the system consists of the following components: The rotating disk valve, attached to the DC motor which actuates it. The valve is provided with slots along the disk. They correspond with the openings on the valve cover in accordance with an ideal valve timing diagram during operation. A valve lining, provided with valve openings to allow passage of charge into the cylinder. The valve lining also serves to separate the intake and exhaust manifolds. It has been designed to be used as a separate valve support fixture for each cylinder, and facilitates both intake and exhaust actions as well. A gasket/sacrificial plate placed between the valve and lining prevents wear and tear of both components by slowly wearing itself down. The gasket material has been chosen in such a way that the action of the valve would not cause any wear on itself, but would wear the slightly softer gasket. It also serves to effectively seal the cylinder. 265

3 VALVE: The design of the system began with the disk valve, and most components were designed around and on the basis of the valve. A draft showing Part Manufacturing Information (PMI) for the valve is given below: Exploded assembly 266

4 The working component of the valve, i.e., the rotating disk, was designed keeping in mind it s ability to incorporate both intake and exhaust cycles during operation. Thus, each cylinder requires only one valve for it s working. The flow path is opened and closed when the notches on the valve disk correspond to the openings on the lining during a controlled rotation. Nimonic 80a was assigned as the material to be used after careful consideration of the requirements and properties needed. Nimonic 80A alloy is a nickel-chromium alloy that is strengthened by the additions of titanium and aluminum. It has high tensile and creeprupture properties at temperatures up to 815 C (1500 F). Properties and Advantages of Nimonic 80A 1. It has an ability to withstand very high temperatures and pressures. 2. Nimonic 80A alloy can be machined using conventional machining techniques used for iron-based alloys. 3. The alloy has low density and high tensile strength. 4. The alloy has good ductility, and can be readily formed using all conventional methods. 5. Nimonic 80A alloy can be welded using conventional welding techniques such as gas-tungsten arc welding, shielded metal-arc welding and submerged-arc welding. 6. Nimonic 80A alloy can be heat treated at 1079 C (1975 F) for 8h and air cooled. 7. The alloy can be forged at temperatures ranging between 982 to 1177 C (1800 to 2150 F). 8. Cold working of this alloy can be done using standard tooling. 9. The alloy can be annealed at 1079 C (1975 F) for 8 hours and air cooled. 10. The alloy can be hardened by cold working. the rotation speed of the valve in relation with the speed of the engine crank shaft. The lining also serves as a makeshift exhaust and intake manifold. The central rib separates the intake and exhaust sides and does not allow the incoming charge to mix with the exhaust gases. This ribbed design also imparts strength and stability to the assembly, minimizing vibrations and improving engine balance. LINING: The valve lining was designed to serve a number of purposes. The valve rotates in a concentric circular groove in the lining which is provided with opening notches to provide a flow path. The notches were designed and placed at specific angles to correspond with the ones on the valve disk according to a desired valve timing diagram. The intake/exhaust can be advanced or delayed by controlling 267

6 that also functions as a gasket, completely seals the combustion chamber from the engine manifold. 3. In this design the slots on the rotary disc corresponding to the inlet and the exhaust valves are open for a time period determined by valve timing diagrams for 4 stroke S.I Engines. However, the area available for the passage of the inlet mixture into the combustion chamber and the passage of the exhaust gasses out of the combustion chamber is lesser as compared to the area available for the same purpose in conventional engines using poppet valves. It has been assumed that since the passage of the inlet mixture or exhaust gases is determined by the pressure difference between the engine manifold and the combustion chamber, a reduction in the passage area available will automatically increase the speed of the passing mixtures thereby delivering the same volume of the mixture as done in conventional engines. 4. It has been assumed that the DC motor can deliver the required RPM constantly and accurately despite the friction the rotary valve will encounter on its surface while rotating against the engine lining. 5. It has been assumed that the materials that have been selected for the rotary valve and the sacrificial plate/ gasket after careful study, will successfully be resistant to very high temperatures occurring in the combustion chamber. 6. To calculate the speed of the dc motor, the slot angles required on the rotary valve as well as on the engine lining, a particular valve timing diagram has been taken as reference. It has been assumed that in this design the principles of the combustion cycle will not change. Thus here the focus has been laid on designing a better method for intake and exhaust of the inlet mixture and the exhaust gases respectively with the assumption that the time periods of the different strokes comprising the combustion cycle will remain unchanged. 7. This assumption concerns the sacrificial plate/metallic gasket being used in this design which has been placed between the rotary disc valve and the engine lining. It has been assumed that since the metallic gasket requires to be still, it can conveniently be press fitted and secured to the desired tightness. overcome weight effects resulting from alignment of operation of the valve. For example, the valve can be employed in a variety of orientations with respect to the material flow path such as the valve can be operated suspended and orientated such that flow path is vertical. In a further embodiment, cooling can be incorporated into various dynamic components in the system to prevent damage to heat sensitive components. References [1] [2] eic/rotaryvalveic.htm#now [3] Conclusion The primary purpose of this paper was to introduce and elaborate a concept of rotary gate valves as a possibility in I.C. engines for automobiles. The goal was to conceptualize a valve mechanism that would not be dependent on a camshaft for its operation, thus eliminating the analogous nature of current cam based systems, and to enable a valve to have continuously variable valve timing, which could be controlled as easily as using a feedback from the speed of the engine to the valve motor. The paper theorizes the working of the valve as would be required for overcoming the difficulties posed by the current systems. With respect to the scope for further improvements to the concept, a few possibilities presented themselves while working on this project. In one embodiment, compressive pressure can be provided by springs located between the bottom plate of the valve housing and the rotating disc. The compressive pressure can be of such magnitude to compensate and/or 269
