What is Overboost and how does it work? What is Overboost and how does it work? Which vehicles can Overboost be used?
A feature that is becoming more common in modern cars is the ability to drive on the left. “Overboost” It is designed to boost the power of a turbocharged engine as needed. It is extremely simple to operate. The ECU program the turbocharger to operate at maximum power when conditions permit. This allows the turbocharger to push more air into its combustion chamber, thereby sending around 10% more power to your wheels.
Overboost gives extra power by allowing more air to the engine. If the engine is operating within the specified parameters, the Overboost function activates automatically. The result? A higher performance engine. The process is quick and prevents the engine overheating.
Understanding Overboost is essential in order to understand its working logic.
To save fuel and reduce emissions, automakers started producing smaller turbocharged engines. However, they did not sacrifice power.
Turbochargers use exhaust gases from your engine to send more compressed oxygen into your cylinders. It works like a bellow blowing on fire to excite the flame. The turbine can spin at speeds up to 200,000 rpm. The turbine spins faster the more exhaust gas it receives. The compressed and made air are sent to the turbines, where they are mixed with fuel. This increases the engine’s power. Turbocharged engines produce more power than non-turbocharged ones of the same power. Excessive air can cause engine temperature and pressure to rise, which is the biggest problem. This causes more stress to the engine components and creates stress.
When calculating how much and how long the engine will take to heat up, engineers consider all of these factors. Excessive and prolonged intake of air can cause engine malfunctions. The engine’s power potential is reduced if there is less air and less pressure.
An overboost function can be added to turbocharged engines to protect the engine and increase engine power. The overboost time is typically limited to between 10 and 20 seconds. The engine will gain about 5%-10% power during this period. This feature cannot be controlled manually by drivers. The system activates automatically at a specific speed, in a particular gear, and when the accelerator pedal has been fully depressed. This is particularly important in situations of critical overtaking.
After a 10-second boost, a Volkswagen Golf GTI Clubsport 2.0 petrol engine produces 261bhp to 286bhp.
The Ford Fiesta ST has a 180bhp engine, but overboost can increase that to 197bhp. Ford Focus RS and Hyundai i30 N models have overboost.
Overboost allows the Volkswagen Amarok Aventura3.0 V6 diesel engine to increase its power from 255bhp down to 268bhp.
