Abstract

The present disclosure relates to a turbocharger system (10) for a light or heavy duty vehicle, a maritime vehicle or a construction vehicle. The turbocharger system (10) comprises a turbocharger device (20), an exhaust manifold conduit (40, 40a), a valve (70), a receptacle (30) for compressed gas and a gas compressor (80) for compressing gas. By opening the valve (70) during a predetermined pulse duration time period compressed gas may be provided from the receptacle (30) to the exhaust manifold conduit (40, 40a) for initial compressor spin-up of the turbocharger compressor (21). The present disclosure is further characterized in that the turbocharger system (10) comprises a cooling means (90), configured to decrease the temperature of the compressed gas provided by the gas compressor (80), and a heating means (100, 100a), configured to increase the temperature of the gas pulse generated by opening of the valve (70). By decreasing the temperature of the compressed gas in the receptacle (30) upstream of the valve (70) generating the gas pulse and subsequently heat up the generated air pulse before being provided to the exhaust manifold conduit (40, 40a), the response time of the turbocharger device (20) can be improved.
