Description

A V tyDe Internal Combustion Engine The invention relates to V type
internal combustion engines. Particularly it relates to a V type engine having a supercharger and air inlet assembly mounted between the cylinder heads.
Engines of the above type are known. See, for example, US4932368 where a supercharger of the Lyshoim screw type is mounted on the cylinder block and US68371 95 where a Roots type supercharger is provided for mounting directly to the cylinder heads of a V type engine. In US6837195 the supercharger has a rotor casing and a pair of mounting flanges formed integrally with the rotor casing, each mounting flange extending laterally of the rotor casing and mounted to the adjacent cylinder head. Air from the supercharger outlet enters a plenum above the supercharger casing and flows from the plenum through air inlet pipes cast integrally with the supercharger casing and into the inlet ports in the cylinder heads. US6027637 shows a similar arrangement where there is a common wall between the air inlet pipes and the adjacent outer wall of the supercharger rotor casing. Both these arrangements complicate the design of the rotor casing and increase the cost and complexity of manufacture. Also, where intercoolers are incorporated, the casing has to be extended to accommodate these, thus increasing the size and complexity of the casting.
It is an object of the invention to provide a V type internal combustion engines having a supercharger and air inlet assembly mounted between the cylinder heads and which overcomes or alleviates the above problems.
According to the invention there is provided a V type internal combustion engine having first and second banks of cylinders, a first cylinder head on the first bank and defining with the cylinders a combustion chamber for each cylinder of the first bank, a second cylinder head on the second bank and defining with the cylinders a combustion chamber for each cylinder of the second bank, each cylinder head having a respective inlet mounting face and inlet ports extending from the mounting face into the combustion chambers, and a supercharger and air inlet assembly mounted between the cylinder heads, the assembly comprising a supercharger, a pair of air inlet casings and a cover, the supercharger having a rotor casing which includes an outlet face defining a supercharger outlet and a pair of mounting flanges formed integrally with the rotor casing, each mounting flange extending laterally of the rotor casing, being mounted to the adjacent cylinder head and having through ports which each open into a respective inlet port, each air inlet casing being mounted to a respective one of the flanges and having an inlet opening at one end and outlet ports at the other end, each outlet port being aligned with a respective through port, and the cover being arranged to cover the inlet openings and extend over the rotor casing to form, together with the rotor casing and the air inlet casings, a plenum, the arrangement being such that air from the supercharger outlet enters the plenum and flows from the plenum through each of the air inlet casings, through the through ports in each of the mounting flanges and into the inlet ports in the cylinder heads.
A primary intercooler may be positioned between the supercharger outlet and the plenum so that air from the supercharger outlet enters the plenum through the primary intercooler. Additionally or alternatively, a pair of secondary intercoolers may each be positioned between the plenum and the inlet opening of each inlet casing so that air from the plenum flows through each of the secondary intercoolers and into the air inlet casings.
The invention will now be described by way of example and with reference to the accompanying drawings, of which: Fig.1 is a cross section through a V-type engine according to the invention, showing part of the cylinder heads and a supercharger and air inlet assembly mounted on the cylinder heads; Fig.2 is a perspective view of a supercharger of the engine shown in Fig.1; and Fig.3 is a perspective view based on Fig.2 with one of a pair of air inlet casings shown fitted to the supercharger.
A V-type engine 11, in this example a V8, has two cylinder heads 12, 13, one on each bank of cylinders. Each cylinder head 12, 13, defines with the associated bank of cylinders, a combustion chamber for each cylinder, each of which is served by a respective inlet port 14 in a conventional manner. In this example, there are four inlet ports 14 in each bank.
Each cylinder head 12, 13 has a respective inlet mounting face 15, the inlet ports 14 extending from the mounting face into the combustion chambers. As will be appreciated, these inlet ports 14 may, as is well known, split to serve two or even three inlet ports in the combustion chamber itself. A supercharger and air inlet assembly 16 is mounted between the cylinder heads 12, 13, the assembly 16 comprising a supercharger 17, a pair of air inlet casings 18, 19 and a cover 21. Where the engine 11 is arranged in a conventional vertical orientation with the banks of cylinders inclined an equal amount from the vertical, then this can be conveniently be referred to as the top cover 21. However, other orientations of the engine are possible for particular applications so that expressions which indicate a particular orientation are used for convenience only.
The supercharger 17 has a rotor casing 22 which includes an outlet face 23 defining a supercharger outlet 24 and a pair of mounting flanges 25, 26 formed integrally with the rotor casing 22. Each mounting flange 25, 26 extends laterally of the rotor casing 22, being mounted to the adjacent cylinder head 12, 13 at a lower face 26 and having four through ports 28, each of which opens into a respective inlet port 14.
A pair of air inlet casings 31 is mounted on the supercharger rotor casing 22, one on either side above the cylinder heads 12, 13. At one end, in this case the top end, each inlet casing 31 has an upper flange 32 defining inlet opening 33 and at the other end, in this case the lower end, a lower flange 34 defining four outlet ports 35, each outlet port being aligned with a respective through port 28 in the supercharger mounting flange 26. Each lower flange 34 has a lower face 36 which abuts an upper face 37 of the respective mounting flange 25, 26. Fasteners, e.g. setscrews or studs and nuts (not shown) extend through holes in the mounting flanges 25, 26 and in the lower flanges of the inlet casings 31 to secure the supercharger and air inlet assembly 16 to the cylinder heads 12, 13. The upper flange 32 of each inlet casing 31 extends over the outlet face 23 of the supercharger rotor casing 22 where it is clamped to the rotor casing 22 by setscrews (not shown).
A cover 41 has a flange 42 which is fastened to the upper flange 32 of both inlet casings 31 and to the supercharger outlet face 23. The cover 41 thus extends over the supercharger rotor casing 22 and the inlet openings 33 to form, together with the supercharger rotor casing 22 and the air inlet casings 31, a plenum 43. A first or primary intercooler 44 is positioned between the supercharger outlet 24 and the plenum 43, centrally above the supercharger rotor casing, and is clamped against the outlet face 23.
One of a pair of secondary intercoolers 45 is each positioned between the plenum and the inlet opening 33 of each inlet casing 31, in this example being in the inlet opening 33 itself.
The arrangement is such that in use air from the supercharger outlet 24 enters the plenum 43 through the primary intercooler 44 and flows from the plenum 43 through each of the secondary intercoolers 44 and into the air inlet casings 31. The air then flows through the through ports 28 in each of the mounting flanges 25, 26 and into the inlet ports 14 in the cylinder heads 12, 13.
In a modification (not shown), the side of each inlet casing 31 which is adjacent the supercharger rotor casing 22 has a vertical face which abuts a corresponding vertical face on the supercharger rotor casing 22. Setscrews fasten the top end of each inlet casing 31 to the supercharger rotor casing 22 to supplement or replace the setscrews in the upper flange 32.
The arrangement allows the use of a relatively simple casting for the supercharger rotor casing 22 while the use of separate inlet casings 31 allows for partial disassembly for servicing without disturbing the drive to the supercharger 17.
