This is the 10th in our series of posts where we are sharing drawings for the White Horse CAD Wobbler Engine. This week we will look at the Wobbler Engine Piston Block.

Next week we will look at the Wobbler Engine Piston Block Stud.

Lets look at the Wobbler Engine Piston Block in a little more detail. If you would like to refer to the PDF engineering drawing it can be found by clicking here… P9999-11101_Rev 1

The Wobbler Engine Piston Block is a straight forward component. The main feature is the bore which has been dimensioned and toleranced to ensure the piston will run smoothly inside it. You may notice the we have specified a much higher surface finish on the bore compared to the rest of the features. This is to ensure the piston slides freely. We have also added a few geometric dimensions that specify the bore must be parallel to the base datum and symmetric about the width datum.

The 3 round bottomed grooves on each side of the piston block are intended to act as cooling fins. This is important because the engine will be auir cooled so increasing the external surface area is important to ensure the piston block does not overheat.
