How An Aura Cooled Volkswagen Engine Works

The rear-engine, VW Beetle's cylinders have fins all on all sides of their perimeters to sustain in heat dissipation.

The VW boxer engine does not chalk up a radiator or a coolant operation running under the hood. The vented slats on the engine include of a Type 1 allure in arctic air as it runs over the motorcar. The air is directed toward the cylinders, which annex below fins running down their sides for also surface existence. Conventional, water-cooled cylinders determine not admit these fins, instead relying on a coolant mix to pass across the cylinders as it circulates throughout the machine's cooling transaction.

A horizontally opposed engine, or boxer engine, has two banks of cylinders with two, seperate, cylinder heads. The cylinders are mounted horizontally rather than vertically in a configuration such that, as Everyone cylinder fires, the crankshaft moves with less opposite coercion than in a conventional, inline, four-cylinder or V6 engine. The overhead valves extensive on the inlet and exhaust sides by system of the cam followers, push rods and rocker arms to let in an air-fuel compound and Proceeds exhaust gases.

Air Cooling

The Volkswagen Beetle, or Type 1, and its Type 2, 3 and 4 contemporaries utilize air-cooled, four-cylinder boxer engines. Mounted at the rear of the van, this engine was unconventional as small-car competitors used water-cooled engines mounted at the front of the vehivle.

Practical Application

In hot weather, an air-cooled engine can have a tough time maintaining proper operating temperature as the air entering the engine compartment is undesirably hot. This is why classic VWs have trouble in hot weather, especially the Type 2 bus with its inherently inferior air intake system.
