Internal combustion engine operation method, involves using excess pressure of intake air compressor for driving turbine or secondary air compressor with insufficient pressure difference before and after throttle valve

摘要

The method involves compressing the air purified by an air suction filter. A line system encloses a throttle valve (18) and a turbine is operated with the pressure difference in a suction tube (12) before and after the valve. The excess pressure of an intake air compressor is used for driving the turbine or the secondary air compressor with insufficient pressure difference before and after the throttle valve. An independent claim is also included for an internal combustion engine comprising an engine block.
