Automotive Turbocharger Market
Automotive Turbocharger Market by Technology (VGT, Wastegate, Electric), Material (Cast Iron, Aluminum), Ice & Hybrid Vehicle, Fuel Type, Off-Highway (Agricultural, Construction, Locomotive), Aftermarket, and Region – Global Forecast to 2025

The Automotive Turbocharger Market in 2017 was valued at USD 14.86 billion and is projected to reach USD 31.61 billion by 2025.

Future demand for electric turbochargers to create opportunities for the automotive turbocharger market

A four-cylinder engine with a turbocharger has the performance of a bigger engine without a turbo. However, due to the turbo lag, turbochargers become inefficient at lower speeds and city traffic conditions. The electric turbocharger, or e-charger, operates with the help of an electric motor rather than waiting for the exhaust gases to eventually bring the impeller up to speed.

The electric turbocharger pressurizes the air available to the engine intake system by using an electrically powered forced-air system. Thus, the air becomes dense and, along with more fuel, produces increased horsepower. The main benefit of an electric turbocharger is that it overcomes the time lag of a conventional turbocharger because the electric turbocharger’s impeller, which pumps air and fuel into the cylinders, spins at 10,000 rpm when it is not needed. So, there is minimal hesitation or lag in engine response when the driver presses the accelerator pedal.

An electric turbocharger works through electric supply from the battery, and a conventional automotive battery would not be sufficient for the electric turbocharger. So, to enable the use of an electric turbocharger, a 48-volt system is required. The use of 48 V architecture will lead to a significant transition in the vehicle power distribution.

Several OEMs are committing to integrate these advanced boosting devices within new platform development. Hence the electric turbocharger is expected to be introduced in 2020-2022. Growing demand for a high-performance car with better fuel efficiency and positive sentiment of the industry towards 48-volt architecture will be the opportunity for the electric turbocharger.

Turbo lag

Turbo lag is the time taken by a turbocharger to respond to the throttle. It is the time needed for the turbine to reach full throttle from an intermediate rotational speed state. The turbocharger delays the boost response after the throttle is opened. This time delay is known as turbo lag. Turbo lag is evident, especially in diesel engines. Turbocharger lag can cause smoke emissions and a significant reduction in the maximum torque available during vehicle acceleration.

Turbocharger lag can be reduced by supercharging, minimizing the moment of inertia of the turbocharger, and reducing the turbocharger friction. Turbo lag is one of the key challenges faced by players in the automotive turbocharger market. OEMs are trying to reduce turbo lag by various innovations. For instance, the Ford EcoBoost engine uses variable cam timing to eliminate turbo lag at low rpm. Ferrari has managed to bring this time lag down to 0.08 seconds in the 488 GTB by using twin-turbo technology. Even TATA, a key player in the Indian automotive turbocharger market is providing the turbocharged engine for its Nexon car. Tier 1 players are doing significant work in minimizing the turbo lag. Some of the examples are electric turbocharger and lightweight of a turbocharger.
