does heat affect engine performance?

Question

i dont care if you say no... it does on my car!

Answer 1

Heat does affect performance. The higher the temperature of the air entering your engine, the less dense it is....Which basically means there is less air in your engine, which doesn't allow for optimum fuel burn. Cold air is more dense, hence why most turbocharged cars have an intercooler. This is so the air can be cooled before going into your engine. There are also co2 kits that freeze the intercooler, further cooling the air. That equals more air in your engine, and you can add more fuel to allow better combustion and more horsepower.

Answer 2

AN engine operates best when it's warmed up. A cold engine is sluggish. However an engine running above the ideal temp of around 180f is also bad news. High temps can and do cause early part failures as well as robbing power. That's why it's important to pay attention to the cooling system with periodic maintenance. Coolant should be flushed and replaced at two year intervals and hoses and belts inspected and replaced if needed. If the car is losing coolant the cause should be found and repaired.

Answer 3

Yes, after a point. Engines don't run well cold either. But there is a point at which power is robbed either by to warm of air and or too warm of an engine.
To hot of a running engine also cause earlier failure of the oil and this will lead to early engine failure. It has even been seen that piston tops have melted due to excessive heat and or too little cooling.

Answer 4

If heat effects your car noticlbly you may need to put in a cooler temp therostat or check you air intake system.

A properly warmed up engine 180 for old school motors, and 195 for newer motor "provided they are not extreme motors" will run there best. This also assumes your able to properly duct in colder air from the outside, and you oil temp is at the 220 degree level where they say it works its best.

Answer 5

Yes, heat does affect engine performance,you may notice on a cool wet day that you have much better engine power np

Answer 6

It relies upon on no count if or not the exhaust finally ends up leaking into the passenger element of your vehicle. vehicle exhaust is poisonous and as quickly as you lose awareness you will probable run right into a tree or a easy pole and which would be undesirable on your engine's overall performance.

Answer 7

yes

Answer 8

Yes it does, heat robs horsepower...... that is a fact.......

Answer 9

it does on all cars
