TLDR
In this paper, a recirculation type exhaust gas cleaning system comprising a turbine driven by the output air of an air pump and adapted to drive a blower for directing a part of the exhaust gas into an air cleaner or a carburetor provided in an engine intake system is described.Abstract:
Recirculation type exhaust gas cleaning system comprising a turbine driven by the output air of an air pump and adapted to drive a blower for directing a part of the exhaust gas into an air cleaner or a carburetor provided in an engine intake system, whereby the maximum temperature in the engine cylinder is reduced and therefore the nitrogen oxide content in the exhaust gas can be decreased.read more

Combustion engine including fluidically-driven engine valve actuator
James R. Weber,Scott A. Leman,Gerald N. Coleman,Kevin P. Duffy,Eric C. Fluga,Jonathan Kilkenny,David A. Pierpoint +6 more
TL;DR: In this paper, the Miller cycle is used to control the timing of valve closing/opening and use of an air supply system to enable the engine operation according to a Miller cycle.
Patent
Engine of a spark ignition type
TL;DR: In this article, an internal combustion engine of a spark ignition type is arranged such that the air-fuel ratio of a mixed fuel to become substantially stoichiometric in the range of from A/F=13 to A /F=16 at the time of running in a high load region and to recirculate exhaust gases into the intake system.

Closed cycle diesel engine
W James Stone,James P Diebold +1 more
TL;DR: In this article, a complete closed-cycle HEAT engine is used for under-water application, and a system to compress the exhaust gases is presented. But the system is not suitable for outdoor applications.
Patent
Supercharging apparatus for diesel and multifuel engines
TL;DR: The TURBO-COMPRESSOR can also serve for starting the engine and driving an AUXILIARY service as discussed by the authors, and it can also be used for starting a diesel engine.
Patent
Exhaust feedback and control system for internal combustion engines
TL;DR: In this article, an exhaust feedback and control system for internal combustion engines is described, where at least one feedback pipe is connected at one end to the engine exhaust pipe and at the other end to engine intake for diverting a fractional portion of engine exhaust and delivering it to the combustion chamber.
