Abstract
Described herein is a turbocharging system comprising a compressor having an air inlet and a compressed air outlet, the compressed air outlet to couple with the intake manifold of the internal combustion engine, a first turbine coupled to the compressor, the compressor driven without using power from the internal combustion engine; and a vacuum compressor coupled directly or indirectly to the first turbine. The first turbine can drive a common drive shaft that includes the compressor and the vacuum compressor or output of the first compressor can drive a second compressor that is coupled with the vacuum compressor. The vacuum compressor can be used to scavenge exhaust from the internal combustion engine.
Claims21
A turbocharging system comprising:
- a compressor having an air inlet and a compressed air outlet, the compressed air outlet to couple with an intake manifold of an internal combustion engine;
- a first turbine coupled to the compressor and fluidly independent of the internal combustion engine, the first turbine including a gas coupling with a combustor, wherein the first turbine is positioned to be driven by gas output from the combustor and the combustor is external to the internal combustion engine;
- and
- a vacuum compressor driven via the first turbine, the vacuum compressor positioned to scavenge exhaust gas from the internal combustion engine and output the exhaust gas via an exhaust channel.
An engine apparatus, comprising:
- an internal combustion engine having an intake manifold and an exhaust manifold;
- a compressor having an air inlet and a compressed air outlet, the compressed air outlet to couple with the intake manifold of the internal combustion engine;
- a first turbine coupled to the compressor and fluidly independent of the internal combustion engine, the first turbine including a gas coupling with a combustor, wherein the first turbine is positioned to be driven by gas output from the combustor and the combustor is external to the internal combustion engine;
- and
- a vacuum compressor driven via the first turbine, the vacuum compressor positioned to scavenge exhaust gas from the internal combustion engine and output the exhaust gas via an exhaust channel.
A vehicle powered by an internal combustion engine having an intake manifold and an exhaust manifold, the vehicle comprising:
- a compressor having an air inlet and a compressed air outlet, the compressed air outlet to couple with the intake manifold of the internal combustion engine;
- a first turbine coupled to the compressor and fluidly independent of the internal combustion engine, the first turbine including a gas coupling with a combustor, wherein the first turbine is positioned to be driven by gas output from the combustor and the combustor is external to the internal combustion engine;
- and
- a vacuum compressor driven via the first turbine, the vacuum compressor positioned to scavenge exhaust gas from the exhaust manifold of the internal combustion engine and output the exhaust gas via an exhaust channel.
