An engine assembly (10) including an internal combustion engine (12) configured to be received in an engine compartment (100) and a heat exchanger (20) having a first conduit (22) fluidly connected to a fluid circuitry (23) of the engine (12) and a second conduit (24) fluidly connecting an interior (108) of the engine compartment (100) to its environment (110). The first conduit (22) is in heat exchange relationship with the second conduit (24). The assembly (10) further includes a forced air system (28) operable in use to provide an air flow from the environment (110) to the outlet (104) via the second conduit (24) of the heat exchanger (20) and the engine compartment (100). The assembly (10) further includes a selector valve (30) configurable to selectively fluidly connect an air intake (18) of the internal combustion engine (12) with the interior (108) of the engine compartment (100) in a first valve position and with the environment (110) in a second valve position.

To provide an engine device with high reliability and high safety in which a pipe conduit in a portion where a blow-by gas having leaked from a combustion chamber is merged with intake air (outdoor air) is not blocked with ice coating even in use in a cold region, especially an arctic region at -20°C or less, a blow-by gas mixed joint configured to introduce a blow-by gas flowing in a returning hose to an intake pipe includes a blow-by gas guide plate that defines introduction space expanding upstream and downstream of a blow-by gas inlet in an intake direction of an intake passage. The blow-by gas guide plate closes an upstream end of a part of the introduction space expanding upstream of a blow-by gas inlet and opens a downstream end of a part of the introduction space expanding downward of the blow-by gas inlet in the intake passage.

The present invention relates to a device (1) for the thermal management of the intake air of a combustion engine (3) equipped with a turbocharger (5), said device comprising: a first heat exchanger (7) placed in the air intake circuit (9), a second heat exchanger (10) placed on the main exhaust line (12) and connected to the first heat exchanger (7) to form a heating loop (A), said thermal management device (1) further comprising what is referred to as a low-pressure exhaust gas recuperation system (14) comprising a first branch-off (141) positioned downstream of the turbine (5b), an outlet (142) positioned upstream of the compressor (5a), and a regulating valve (140), the second heat exchanger (10) being positioned between the turbine (5b) and the first branch-off (141), the main exhaust line (12) comprising a bypass (26) between a second branch-off (201) positioned on the main exhaust line (12) upstream of the second heat exchanger (10), a bypass device (200) able to manage the circulation of the exhaust gases, and an outlet (202).
摘要:
Various methods and systems are provided for an intake manifold for an engine. In one example, an insert comprises an annular body having a top surface, bottom surface, inner surface, and outer surface. The insert further comprises a first groove for coupling an intake air port of an intake manifold to a cylinder head, a second groove for circulating gaseous fuel received from a gas runner of the intake manifold, and one or more openings to fluidically couple the second groove to an interior of the intake air port. The insert is configured to mix gaseous fuel and intake air at a coupling location between the intake manifold and the cylinder head.
摘要:
An air heater for heating intake air for an internal combustion engine is provided. The air heater may have a heating element with improved air flow redirection. The air heater may include a controller that is formed as an integral component with another component of an internal combustion engine such as an air intake manifold cover. The heater may include thermocouple circuitry for sensing the temperature of the heating element. Methods of calibrating the thermocouple circuitry are also provided. Methods of controlling the air heater while performing engine start are also provided.
摘要:
Ein flüssigkeitsgekühlter Ladeluftkühler (7) zur Änderung der Temperatur von Frischgas einer Brennkraftmaschine, mit einer oder mehrerer Frischgaslagen (15) und einer oder mehrerer Wasserlagen (16), wobei sich die Frischgaslagen (15) und die Wasserlagen (16) flächig erstrecken und von einem Gehäuse des Ladeluftkühlers (7) aufgenommen sind, soll derart gebaut werden, dass gleichzeitig eine Kraftstofftemperierung der Brennkraftmaschine erreicht wird und der zu temperierende Kraftstoff von der zu kühlenden Ladeluft mit hoher Sicherheit räumlich getrennt ist. Dies wird dadurch erreicht, dass an einem nach außen weisenden Wandabschnitt (14) des Gehäuses des Ladeluftkühlers (7) ein Kraftstoffkühler (6) zur Änderung der Temperatur von Kraftstoff, welcher der Brennkraftmaschine zugeführt werden soll, angeordnet ist.
