I had a VW 1600 engine that wanted to be torn down. And I had a digital camera. Now, you may have a photograph gallery of the innards of that engine, which makes for a simple walk-through of the elements make your automobile go.
This twin port 1600 engine got here from a 1970 Tremendous Beetle. It sits right here in my store, awaiting a teardown.
VW Engine Consumption Manifold
That is the consumption manifold. A carburetor sits on the flange on the high and feeds a fuel-air combination into the engine.
VW Engine Valves
After the fuel-air combination travels down the consumption manifold, it arrives on the cylinder head. It finally wants to finish up contained in the cylinder, however solely on the proper time. Proven listed here are the rockers and the valves. The rocker arms depress the spring-loaded valves, opening them to permit the consumption cost to enter at exactly right second and, barely later within the cycle, to permit the exhaust gases to go away.
VW Engine Distributor
With the fuel-air combination within the cylinder, one thing must ignite it. Excessive-voltage sparks are triggered by the ignition factors, that are inside this distributor. Then the rotor, additionally contained in the distributor, routes the sparks to the spark plug within the applicable cylinder.
VW Engine Being Torn Down
With the consumption and exhaust manifolds eliminated, the engine begins to look extra manageable. The flywheel has additionally been eliminated on this image.
VW Engine Being Torn Down Entrance
That is one other view of the engine with the equipment and manifolds eliminated. The heads (the issues on the farthest proper and farthest left of this image) would be the subsequent to go.
VW Engine Rocker Arms
In a earlier image, we noticed the rocker arms in place on the engine. The rockers are within the middle of the image, and the lengthy rods on the skin of this image are referred to as pushrods. In a pushrod kind of engine corresponding to this one, the pushrods push up on one finish of the rocker. The opposite finish then pushes down on a valve, inflicting it to open.
VW Engine Heads
The cylinder head incorporates the ports that enable gas and air into the cylinder and exhaust gasses out of the cylinder. Additionally they comprise the valves that open the passage to these ports at solely the proper occasions within the engine’s combustion cycle. Within the cylinder head on the left, we see the ports that connect with the consumption and exhaust manifolds. Within the cylinder head on the proper, we see the valves, that are usually on the within of the engine.
VW Engine Circumstances Cut up
Not like most automobile engines, and extra like a bike engine, VW 1600 engine instances break up into two elements. Automobile and truck engines extra sometimes consist of 1 strong block into and onto which the engine is constructed.
VW Engine Camshaft
A camshaft controls the timing of valve openings. The cam lobes (the rectangular issues) push on pushrods (or instantly on the valves in an overhead cam engine) to trigger the valves to open.
VW Engine Crankshaft
In an engine, reciprocal linear movement (pistons going up and down) is transformed into rotary movement. The elements on this image make that occur. The pistons transfer up and down within the cylinders because the explosions occur. Connecting these pistons to the crankshaft are the conrods (brief for Connecting Rods). As a result of the purpose on the crankshaft to which the conrod connects is off of the middle axis of the crankshaft, the reciprocating movement of the piston and conrod causes the crankshaft to rotate.
