Publication number: 20120198836Abstract: Otto intake-cycle controlled-air (throttled) internal combustion engines suffer from parasitic pumping losses associated with partial vacuums developed in their intake manifolds and in the cylinders above their pistons. To solve this problem, there is provided individually partitioned dry-sump crankcases dynamic pneumatic coupling pressure reduction cycle system and method that reduce the damaging parasitic effects of the differential pressure about a piston head during an intake cycle which is a source of part-load pumping-loss friction. This closed loop system includes an independent supplemental mechanical fail-safe system of a turbo-compound engine variant for pneumatic coupling of individual cylinder-crankcase volumes. It does not alter the cylinder homogeneous mixture charge integrity and stability. The system is applicable to several engine configurations, such as controlled air intake or uncontrolled air intake combustion engines, using different fuel types, either in liquid or in gazeous state.Type: ApplicationFiled: October 14, 2010Publication date: August 9, 2012Inventor: Jean-Pierre Marcil

Publication number: 20120198837Abstract: A system for controlling an exhaust driven turbocharging system includes a turbocharger having an exhaust inlet, a discharge outlet, a compressor air inlet, and a compressor outlet, a compressor bypass valve having a control port, an inlet port, a discharge port, and a valve for opening and closing the discharge port, and an engine having an air inlet and an exhaust outlet, and may include a wastegate. In the system the compressor outlet of the turbocharger is connected to the air inlet of the engine and is connected to the inlet port of the compressor bypass valve. By controlling the compressor bypass valve and the wastegate higher turbine inlet pressures can be generated for use in other areas of the system. This is achieved by opening the compressor bypass valve in an unconventional area of the internal combustion engine's range where it would normally remain closed.Type: ApplicationFiled: February 9, 2012Publication date: August 9, 2012Inventor: Peter Johann Medina

Publication number: 20120198841Abstract: A component of an exhaust system may convey exhaust gas between one or more inlets and one or more outlets and may include at least one fluid path in thermal communication with the exhaust gas. The fluid path may be defined by an external surface of the component and a cover plate attached to the external surface. The fluid path may be connected to a coolant source.Type: ApplicationFiled: October 13, 2010Publication date: August 9, 2012Applicant: WESCAST INDUSTRIES, INC.Inventor: Clayton A. Sloss

Publication number: 20120198842Abstract: An internal combustion engine has at least one combustion chamber and an exhaust gas system arranged on an exhaust gas outlet port. The exhaust gas system includes at least one secondary air injection device for injecting secondary air into the exhaust system between the combustion chamber and an exhaust emission control system arranged in the exhaust gas system. During operation of the internal combustion engine, a residual gas content in the combustion chamber can be changed. The secondary air injection site on the exhaust gas system is arranged so far from the combustion chamber that injected secondary air flows back into the exhaust gas outlet port due to back-flowing exhaust gas in the exhaust gas system but does not flow back into the combustion chamber. This makes it possible to comply with SULEV emission limits even for engines having many combustion chambers and/or exhaust gas turbochargers.Type: ApplicationFiled: March 6, 2012Publication date: August 9, 2012Applicant: Bayerische Motoren Werke AktiengesellschaftInventors: Manfred Miklautschitsch, Samuel Bucher, Stefan Babernits, Julian Becker
