How does engine heat works? I tried to calculate some stuff, yet the tests do not turn out like the theory. This is because the heatsinks have also to counter heat generated by he Engine. Yet I do not know how to calculate this.

but by how many heat does an engine decrease the heatdissipation?

Depends.


No seriously.

Depends on your speed and the ambient temperature.

Since all we can go by is the percentage of heat on your heat scale that is used up standing still with engines on, "walking", or "running", it's a bit hard to calculate how much heat the engine is dumping into the mix. I know on a cooler map for most of my mechs I run around 3-4% at full speed. On hot maps it can be as much as 10% at full speed and 6% just standing there.

It's in a Command Chair Post, Breakdown 66% Thottle is -1 SHS, Greater than that it's -2 SHS.

A lot of it is explained in Thomas Dziegielewski's "Breakdown" thread.

WATER, AMBIENT TEMPERATURE AND HEATSINKS

There are advantages/disadvantages to be had in putting heatsinks in certain components on a mech, especially pertaining to water and other cooling features.

+ The deeper in water a component containing heatsinks is, the more bonus cooling those heatsinks will do. Having two heatsinks in your right leg and your right leg being 75% submerged in cooling water will give those two heatsinks a 75% cooling boost.

- Steam will emanate from components containing heatsinks if they are being cooled by water or if the ambient temperature is cooling your mech in any way. You will start to see this effect when the mech is at least at a 30% heat level.

Although hard to see it will allow enemies to target components that contain a majority of your heatsinks.

MOVEMENT HEAT

Your engine generates heat the higher your throttle is.

At 66% throttle the engine generates heat up to the equivalent of 1 single heatsink.
At 100% throttle the engine generates heat up to the equivalent of 2 single heatsinks.

HEATSINKS SINGLE VS DOUBLE

EXTERNAL

Single : 0.1 heat dissipation per heatsink per second. Heatbase -1.0 per heatsink.
Double : 0.14 heat dissipation per heatsink per second. Heatbase -1.4 per heatsink.


INTERNAL - each engine has a set amount of internal heatsinks depending on its strength.

Single : 0.1 heat dissipation per heatsink per second.
Double : 0.2 heat dissipation per heatsink per second.

There are also Heat Scaling (that is, "Ghost Heat") and now Quirks, that will alter the heat-related formuae.

Ok, thx lot, that helps the math a lot.

Hmm, learn something new everyday! Good info in here, and a good question aswell.

The engine itself isn't a major source of heat...the actual fusion part that is. The heat comes from the massive energy draw through the electrical delivery/conduit/wiring system that various systems demand during use/operation...propulsion, weapons, etc. The containment system of the fusion gen likely produces some heat since it's magnetic field would be electrically generated, but that draw and heat production is likely relatively fixed.

Consider it like a power supply on your computer that runs very, very cool...but based on the system draw for your various components, the wiring coming from that cool running PSU can be very warm since the generated electricity is going to flow out from a relatively centralized location, hence the benefit of having heat sinks at the engine.

That being said, various systems/components on the mech will generate heat at their source of energy usage...like a PPC. It would make sense to localized/non-centralized heat sinks to facilitate cooling of these various systems since they are also producing heat away from the engine.
