Blow-Down Kits

When the exhaust valve opens, combustion particles escape from the cylinder and cause a blowdown. Since there is this exhaust blown loss during the cycle, the time of the exhaust valve opening will also have an impact on the engine's efficiency. The timing of the Exhaust valve opening affects this loss. It should be noted that this exhaust blows off with a 2% loss. which will have a less significant impact on the engine's efficiency than the other two losses (Time loss-6% and Heat loss-12%).
