摘要： An internal combustion engine in which volumetric efficiency is improved by installing a non-return valve, such as a reed valve (16), upstream of the normal inlet valve (not shown), to control air or fuel-air mixture entering the input port (20). In addition, the ram pipe (23) is made longer than usual: sufficiently long so that, at low engine speeeds, the momentum of the air of fuel-air mixture within the induction system is sufficient to force extra volume past the reed valve (16) to pressurise the gas retained between the inlet valve and the reed valve. Also described and claimed is an engine in which power and torque are improved by adding an extra port or ports in the side walls of the cylinder or cylinders. Such additional ports may be used for inlet combustion gases, or for exhaust gases.

摘要： A method of operating an automotive type internal combustion engine to improve the efficiency and power, fuel economy, and emission control is obtained by phase shifting of both the intake and exhaust valve timing schedules or events, couples with the use of reed valves in each intake port to restrict the backfill of exhaust gases into the intake port, and essentially unthrottled operation except where necessary to maintain engine stability, the reed valves also providing for a controlled internal EGR system. The phase shifting and use of intake reed valves will optimise the intake and exhaust event timing at the four major engine operating conditions of idle speed, part load, and wide open throttle low speed and high speed operation.

摘要： An internal combustion engine (10) in which a minor portion of the air-fuel mixture being flowed to the combustion engine chamber is withdrawn through a fluid withdrawal passage (50). The fluid withdrawal passage enters the curved outlet section (26) of the intake passage (24), with its inlet at the convexly curved interior surface (28) of such outlet. The side stream of air-fuel mixture is withdrawn by application of suction to the outer end (54) of such fluid withdrawal passage. Withdrawal of a side stream of air-fuel mixture in this fashion has been found to substantially increase the rate of flow of air-fuel mixture to the combustion chamber (20) during the charging step of engine operation. The fluid withdrawal apparatus and method of the invention are potentially applicable to many other types of fluid flow systems comprising a flow path with a curved portion, through which it is desirable to increase fluid velocity and volumetric flow rate.

摘要： The internal combustion engine includes a compressor for supercharging intake air, an EGR device for introducing EGR gas into an intake passage at a position on an upstream side relative to the compressor, and a collecting pocket that is provided at an outer circumference of a compressor inlet and that collects condensed water generated inside the intake passage on an upstream side relative to the compressor. The collecting pocket opens towards the upstream side of the compressor, and is formed in a circular ring shape that surrounds the outer circumference of the compressor inlet. The collecting pocket includes a partition wall that holds back a flow of condensed water that attempts to move in a downward gravitational direction inside an internal space of the collecting pocket.

摘要： A method for operating a turbocharged internal combustion engine (1), comprises the steps of operating the engine (1) by feeding combustion air and/or fuel into one or more combustion chambers (3a-3f) via intake openings/inlet valves (4a-4f), combusting the air and fuel and having a flow of exhaust gases flow out via exhaust openings/outlet valves (11a-11f), with the flow of exhaust gases driving a turbine portion (20a) which in turn drives a compressor portion (20b) for compressing combustion air prior to being fed into the one or more combustion chambers (3a-3f). The secondary air injection means (25-27) are activated for injecting pressurized secondary air into the engine (1) during an accelerating operation of the engine (1), in such a way that during said accelerating operation of the engine (1), one or more loads of pressurized secondary air are injected into the outlet manifold (12).

摘要： Die vorliegende Erfindung betrifft ein Ansaugelement 1 für einen Verbrennungsmotor mit einem in einem Hohlraum 5 des Ansaugelements 1 angeordneten Regelelement 10, das wenigstens teilweise in und gegen die Strömungsrichtung von Luft durch den Hohlraum 5 beweglich angeordnet ist. Das Regelelement 10 ist derart gestaltet ist, dass sich ein Regulierungsringspalt 6 bei Bewegung des Regelelements 10 verengt beziehungsweise verbreitert, und durch den Hohlraum 5 strömende Luft am Regelelement 10 einen Venturi-Effekt erzeugt, wodurch sich das Regelelement 10 selbstregulierend bewegt. Diese Selbstregulierung kann eine gleichbleibende Strömungsgeschwindigkeit der Luft bewirken, wodurch sowohl eine optimale Vermischung der Luft mit dem Kraftstoff in unterschiedlichen Betriebszuständen des Verbrennungsmotors ermöglicht wird, als auch eine optimale Verwirbelung der Luft in unterschiedlichen Betriebszuständen des Verbrennungsmotors erzielt wird.
