Thermal insulation can cut CO2 emissions
Thermal insulation for the engine bay of a car could have environmental benefits many motorists are not already aware of.
While insulating the engine bay of a vehicle helps to keep excess heat from reaching passengers in the interior cabin, it can also help the engine itself to reach its intended temperature quickly, and to stay there throughout a journey.
Doing so helps the engine to run more efficiently – and can help to reduce CO2 emissions coming from the vehicle’s exhaust.
The Citroen PureTech engine, now available on petrol models in the C3 and DS3 ranges, has its own way of achieving a similar effect.
By using Split Cooling technology, the cooling circuits in the head and the cylinder block operate separately when the engine is cold.
This allows the interior cabin to warm up faster, as well as achieving the emission-reducing effect described above.
For vehicles without Split Cooling technology, however, the simple addition of thermal insulation could achieve a similar effect.
Performance felts and foams for the engine bay can add thermal insulation that is moulded to the shape of the engine for optimal performance.
