Alfa Romeo 4C Engine Part 2, The Bottom End
note, I can't get the pictures to post inline with the text so for now they are in clickable thumbnails at the bottom of each post
I occasionally hear people say that the 4C isn't an exotic car because it has a small 4 cylinder engine. What I think these people fail to realize is the the 4C's engine is an exotic car engine, it's just scaled down to match the size of the car.
The purpose of this article is to explain to owners and potential owners just how advanced the 4C's engine really is. If you have read part one, which deals with the head and camshaft timing system, great, if not, it's OK to start here, but please read part 1 also which deals with the engine's top end.
Let's get right into it, and start with the block. The block is the main structure of the engine which contains the pistons and crank shaft. In the case of the 4C. It's an aluminum block to save weight and it's fitted with cylinder liners made from GOE300 steel. These liners are integrated into the block and are there to prevent rapid cylinder wear.
So far this is all pretty standard stuff, an aluminum block with steel or cast iron sleeves is pretty common.
