TL;DR: An exhaust-gas recirculation (EGR) valve includes a rotary drive as mentioned in this paper, which allows operation of a valve member that can be rotated around a rotational shaft.
Abstract: An exhaust-gas recirculation (EGR) valve includes a rotary drive. The rotary drive includes a cam member that has a cam profile. The rotary drive permits operation of a valve member that can be rotated around a rotational shaft. During the course of a closing movement, the EGR valve can, toward the end of the closing movement, move towards a valve seat in a direction that is generally parallel to a direction of flow through the valve seat.

TL;DR: In this article, a clean combustion engine system with a two-cycle engine vehicle is presented, which is supplied near the end of each power stroke with an initial charge of pure air for purifying and cooling the engine cylinder and a following fuel-air charge which enters the cylinder in a manner that achieves efficient combustion during the next power stroke.
Abstract: A clean combustion engine system having a two cycle engine vehicle is supplied near the end of each power stroke with an initial charge of pure air for purifying and cooling the engine cylinder and a following fuel-air charge which enters the cylinder in a manner that achieves efficient combustion during the next power stroke. Air is supplied to the engine through a large plenum chamber from a compressor powered by the engine. Fuel flow to the engine is regulated by a carburetor throttle valve and a timing valve which opens and closes in timed relation to the reciprocating motion of the engine piston. Air flow to the engine is regulated by an air valve operated by a governor in response to both throttle valve setting and engine speed.

TL;DR: In this article, the authors present a plant consisting of a device for interrupting the travel of the lever 6 that controls the injection pump 2 and is connected to the accelerator 10, and a mixer group 12 placed along the manifold for the induction of air to the cylinders.
Abstract: The plant in question comprises a device 10'-11 for interrupting the travel of the lever 6 that controls the injection pump 2 and is connected to the accelerator 10, and a mixer group 12 placed along the manifold 4 for the induction of air to the cylinders, comprising two separate parallel pipes 13-14, the first of which, namely pipe 13, provided with a first throttle valve 15 movable between two extreme positions, that is to say a position for opening the air passage when the engine is running on diesel oil, and a portion for closing the air passage when the engine is running on a mixture of diesel oil and gas; and the second of which, namely pipe 14, provided with a Venturi tube 17 and with a second throttle valve 16 for blocking the air passage, movable continuously and connected to the accelerator 10, the said Venturi tube 17 being connected to a pipe 21 for the supply of gas at low pressure; the said pipes being jointly provided with an air passage area at least identical to that required for maximum engine air induction.

TL;DR: In this article, a two-stroke cycle internal combustion engine without crankcase scavenging is disclosed which is able to operate in a four-stroke mode at cranking and idle speeds, using a turbocharger driven by exhaust gases to recharge the cylinder with fresh air or an air/fuel mixture.
Abstract: A two-stroke cycle internal combustion engine without crankcase scavenging is disclosed which is able to operate in a four-stroke mode at cranking and idle speeds. The engine utilizes a turbocharger driven by exhaust gases to recharge the cylinder with fresh air or an air/fuel mixture. An auxiliary inlet valve responsive to pressure within the cylinder enables the engine to operate in a four-stroke mode, thus eliminating the need for an externally driven air pump when the engine is either idling, being started, or under light loads where turbocharger boost is too low to supply sufficient flow of air or an air/fuel mixture.

TL;DR: In this paper, a two-stroke cycle engines, either with Diesel injection or mechanical injection, are described. But the disadvantage of the straight-through or unidirectional flow scavenging system is not only the disadvantage that the...
Abstract: This invention relates to fuel-oil internal combustion engines; particularly, two-stroke cycle engines, either with Diesel injection or mechanical injection. Such engines, when embodying straightthrough, or unidirectional flow scavenging systems, exhibit not only the disadvantage that the...

TL;DR: In this paper, it was shown that the power of an internal combustion engine is determined by the speed of revolution and the quantity of fuel that can be burned in the cylinder during a power stroke.
Abstract: This invention relates generally to internal combustion engines. It is known that in internal combustion engines the power is determined by the speed of revolution and by the quantity of fuel that can be burned in the cylinder during a power stroke. The quantity of fuel that can be burned...
