Looking at this picture, I noticed that engines are not parallel aligned to the fuselage. Instead, they seem to be in-bound aligned.
Am I correct ? . If so, why they are installed that way ?, Is this a common pattern in all aircrafts ?.

I'm not sure why the engines appear to mounted the way they are in this picture, but canting the engines on aircraft with aft mounted powerplants is almost universal. They are mounted with the engine inlets outboard a few degrees. One of the explinations that I remember from one of my type rating ground schools regarding the outward canting of the engines (as seen from the front) was to minimize the rudder forces required in the case of engine failure. Also, it's common to mount the engines on larger single-engine aircraft with a significant cant. Next time you get a chance go look at a late model Bonanza. It will really surprise you. You'd think the airplane would fly sideways through the air.

I have read posts about this question previously. The consensus was that it is due to the bow wave generated by the nose of the aircraft. It's like a boat moving through the water. You can see the lines of water forming an angle with the nose, as if it had caught a rope (not sure about the picture of that ). With the planes it's the same thing but with air so you can't see it. And engines are tilted inward to meet the greatest amount of air which will be coming in that angled direction. Don't know if I was clear
