Engine intake manifold

Intake manifold for an engine

Blower housing for an engine

A variable valve timing apparatus, and internal combustion engine incorporating the same, that allows the timing of the opening and/or closing of intake and/or exhaust cylinder valves to be altered relative to a reference timing. As a result, the timing of the valve event can be adjusted relative to a phase of the crankshaft and/or the cycle of the pistons.

Engine

A cylinder head assembly and a method of providing an air-fuel mixture from a carburetor to a cylinder of an internal combustion engine are disclosed. The cylinder head assembly includes a cylinder head and a component coupled to the cylinder head. The cylinder head includes a first port having a first passage linking a first end to an intersection, and a second passage linking a second end to the intersection, where the intersection includes an abrupt transition between the first and second passages. The component includes a tongue that protrudes into the first passage from the first end to proximate the intersection, where the tongue is positioned along at least a portion of an inner side of the first passage, and where the tongue is gradually-reduced in thickness at least proximate the intersection.
