Load a node in a block through a module.

Hello,

In one of my node types, I display 5 blocks. These blocks display information from master node. So I loaded the array $node in these blocks by module.

This is precisely where the problem lies. To get to transmit the information node in the blocks, I used the function hook_preprocess() by adding the line: $node = node_load(arg(1)); the problem is that it creates me an error in taxonomy and especially that node_load() works with all types of node.

It should therefore that I can add one if ($node->type == 'modele_2r') {}

I think that there should exist a special function to load a node in a block?

I hope you can help me!

That's part of my module that I load the 5 blocks to the node:
