c) Explain the function, operation, and construction of the components/assemblies of the engine from one of the vehicles you have chosen (i.e. cylinder block, cylinder head, flywheel, inlet and exhaust manifolds) P3.

Basically I need to know about the example engine parts shown above, block, head, flywheel and manifolds. I got the feedback today and he says I haven't gone into enough depth! My deadline is tonight at midnight, and I figured this would be a good source of info! The engine as chosen was the Rover V8 as fitted to the newer disco 4.6l, but I dont need to be too specific as I don't think the lecturer knows much about landies! I just need info about the RV8 as used in LRs as far as the components above, what are they made from, how are they made to do the job specifically ie. heavy flywheel to give good momentum and torque. Any help? :eek:
 
if yer told us what you have wroted we might be able to fill in teh blanks but we sure as ell int likely to do the whole fooker fer yer. now go and earn yer grant

What grant! cost me a grand to come here this year!

What I wrote when I rushed it in for the feedback date was;

c) The rover V8 engine is an eight cylinder engine layed out in a V format. There are 2 valves per cylinder, inlet and exhaust, and these are operated by pushrods from the single camshaft which operates the hydraulic tappets. The block and head are made from aluminium, which means that although this is a large engine, it is extremely light, which lead to its use in many fast sports cars such as the TVR Chimaera and the westfield Seight. It is water cooled, with usually one single radiator mounted to the front of the engine to lose excess heat. The flywheel on the rover v8 differs with its application, that is in the landrover discovery, it will be fairly heavy to keep high momentum when a good deal of torque is required, however when used in a sports car, it will be lightened to provide better acceleration and throttle response.

I'm finding it pretty hard to find actual information about how and why they are made as they are :rolleyes:
 
ye rmight want to touch no things like stroke and bore and fuel system as thems the bits wot give yer injun most of it performance carahcahriskkitts.
 
Aye, GEMS v Lucas Hotwire v Flapper airflow meters v twin 1 3/4" SU's would be a ggod un. The May edition of LRE went into detail about the casting process of the blocks and heads and how crap the LR manufacturing was as they weren't too fussed about the positional centres of the bores, which we know leads to problems. The "new" ones are all done using the Cosworth casting process (a bit complex - me bro used to work there) and are precision engineered units and bullet proof. The big problem you can mention are the NickaSil wet liners used in the block, as they slip if the engine overheats. Download the RAVE disk, it has all the tech info on the engine and decent exploded views of the components.

personally i'd a chose a simpler engine like an old vw or mini lump but you live and learn:D

I needed a wet sump and a dry sump engine with different amounts of cylinders. my dry sump was a van diemen formula first. uses a modified 4cyl XR2 carb engine! so i needed a wet sump with not four cylinders. Rover v8 sounded like a good idea!

oh! **** takin over now:rolleyes: hope it goes well falump.

and 27 mins to go:eek:
 
can anyone help me out with the inlet and exhaust manifolds? what are they made from and why? is there anything special about them on this engine?

Tar
 
not to worry, wikipedia is the students friend! Just a bit of "engineers mathematics" and "light vehicle service and repair" to finish off tomorrow. Thanks for your help guys!
