An air intake system for a combustion engine includes an air intake duct in fluid communication with an engine intake manifold and a conduit component inserted into the air intake duct along a first assembly direction. The air intake system also includes a hydrocarbon (HC) trap secured to the conduit component within the air intake duct. The conduit component defines at least one retention feature to maintain a position of the HC trap such that removal of the HC trap from the air intake duct results in structural compromise of the at least one retention feature. The air intake duct is also configured to shield the at least one retention feature from user access to inhibit user removal of the HC trap.

A pipe fixing device includes: first and second clamps that fix a pipe; and first and second engaging parts that are fixed to the pipe and engage respectively with the first and second clamps. The first clamp and the first engaging part configured to engage with each other such that the first engaging part is restrained from moving toward one side in an axial direction of the pipe and from moving in a circumferential direction of the pipe relative to the first clamp. The second clamp and the second engaging part configured to engage with each other such that the second engaging part is restrained from moving toward another side in the axial direction of the pipe and from moving in the circumferential direction of the pipe relative to the second clamp.

Blow molded plastic components are disclosed having integrally formed brackets, formed together with the component in the molding step. A method of blow molding is disclosed for integrally forming brackets onto a blow molded component. More specifically, the disclosures relates to a blow molded plastic component having a bracket formed integrally in the blow molding process and configured to rotate onto and lockably engage undercut features or lugs formed integrally on the outer surface of the blow molded component, all features formed during the molding process.

An engine assembly includes an engine structure and an intake manifold assembly coupled to the engine structure. The engine structure defines first and second banks of cylinders. The intake manifold assembly includes first and second plenums and first and second sets of runners. The first and second plenums are located laterally between the first and second banks of cylinders. The second plenum is located laterally between the first plenum and the second bank of cylinders at first and second longitudinal ends of the intake manifold assembly and laterally between the first plenum and the first bank of cylinders at a medial region of the intake manifold assembly.

In an engine compartment, a separation wall is provided between an intake pipe, which runs around to a rear side of the engine from a lateral side of the engine, and the engine. On an outer side of this separation wall, a travel wind guide having a vertical wall portion that opposes the separation wall with the intake pipe being therebetween is provided. The travel wind guide guides vehicle travel wind that is introduced into the engine compartment in a manner to cause the vehicle travel wind to flow along the intake pipe on the outer side of the separation wall.

An off-road vehicle includes a frame and an engine. The engine includes a cylinder block and a cylinder head, on which an exhaust passage is arranged. The cylinder head is provided with a supplementary air supply passage for mixing air into the exhaust gas discharged from the combustion chamber. Alternatively, the supplementary air supply passage can be included in the exhaust system, such as in a cylinder head mounting flange of the exhaust pipe, upstream of an oxygen sensor and first and second stage catalytic converters. The exhaust gas from the engine is further oxidized by air, which reduces the content of components such as CO and NOx in the exhaust gas, improving environmental protection.

A filter device is provided with a filter housing and a filter element arranged in the filter housing. The filter element is provided with an annular filter medium body that has an inflow side. The filter housing has a dirt collecting region in flow communication with the inflow side of the annular filter medium body. The dirt collecting region has an annular circumferentially extending configuration. A flow-tight separation element is arranged at or adjacent to the annular filter medium body. The dirt collecting region adjoins the flow-tight separation element. An inflow region is positioned at the inflow side of the annular filter medium body and immediately adjoins the dirt collecting region. The dirt collecting region has a radial extension relative to a longitudinal axis of the annular filter medium body, and the radial extension of the dirt collecting region is larger than a radial extension of the inflow region.

A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.

An intake system for an internal combustion engine may include an air inlet; a forced induction device downstream from the air inlet; an intercooler downstream from the forced induction device; and an intake conduit configured to guide air from the intercooler to an internal combustion engine. In addition, the system may include a condensate retaining structure associated with the intake conduit and configured to restrict the flow of condensate through the intake conduit.
