Why does your Car Lose Power with Heat?

 

The summer heat does not sit well with your car. When the outside temperature exceeds 35 C, your engine loses about five horsepower (up to 15 hp in some turbo engines) and, in addition, increases fuel consumption by an average of one liter per 100 km.

There are also other drawbacks in brakes (they become fatigued due to overheating), tires (their duration is reduced by 15%), body paint that loses its shine, and the interior, which tends to discolor and deform. All this is inevitable, but you can get the heat to affect your car as little as possible:

Engine Intake Air too Hot:

All engines, be they diesel or gasoline, need to introduce air into the cylinders in order to burn the fuel. When the temperature is high, the air contains a lower proportion of oxygen and the mixture does not burn as easily so that the performance of the engine declines. This is especially seen in turbocharged or air compressor engines (they lose up to 15 hp) since, since these engines need more air to operate, the lack of oxygen affects them more. There is nothing you can do to avoid it, but you will notice a further loss of performance if you carry the dirty engine air filter or the spark plugs too many kilometers, two cheap maintenance operations.

Overloaded Cooling System:

The cooling system ensures that the engine does not exceed the normal temperature at which it operates (between 85 and 95 degrees). In summer, especially when you circulate at less than 40 km / h, the electric fan has to act more often and it lowers the performance to the motor (around 2 CV). Fortunately, the increase in consumption is negligible. It cannot be avoided, but if you change the coolant every four years and monitor its level once a month, you will help your car.

Air Conditioning:

Vehicle air conditioning uses a motor-driven compressor. Therefore, each time it is started, it subtracts about four horsepower from average performance. You could stop using the air conditioning to avoid it, but the loss of power generated by having it running is so small that it is negligible. The increase in consumption (which exists) is not exaggerated either.
