Abstract
Internal combustion engine with as exhaust pressure regulator (10) arranged in an exhaust conduit (5) for regulating the exhaust counter-pressure in the engine cylinders. Upstream of the exhaust pressure regulator, the exhaust conduit communicates via valve means (17) with the intake side of an air compressor (14) to make possible pre-charging of the compressor during engine braking.
Claims8
An internal combustion engine comprising:
- an exhaust conduit;
- a shutter device at an outlet of said exhaust conduit for regulating exhaust counter pressure in the engine's cylinders during engine braking;
- a first conduit having a first end connected to said exhaust conduit, upstream of said shutter device;
- and
- a valve connecting a second end of said first conduit to an inlet of an air compressor.
2 more elements
An internal combustion engine comprising:
- an exhaust conduit;
- an air compressor that selectively suctions exhaust at higher than atmospheric pressure from said exhaust conduit and air at atmospheric pressure from a surrounding atmosphere;
- and
- a first conduit with one end directly connected to said exhaust conduit and that receives the exhaust at higher than atmospheric pressure and a second end that provides the exhaust at higher than atmospheric pressure to said air compressor.
1 more element
An internal combustion engine, comprising:
- an exhaust conduit;
- a turbo-compressor having a turbine in communication with said exhaust conduit;
- an exhaust pressure regulator in communication with an outlet of said turbine, said exhaust pressure regulator comprising a shutter and a regulator valve that controls said shutter through a pneumatic regulator;
- a first conduit having one end opening into said exhaust conduit upstream of said turbo-compressor;
- an air compressor;
- and
- a valve selectively connecting an inlet of said air compressor to a second end of said first conduit and a surrounding atmosphere.
