2. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   The first refinement in crankcase ventilation was the road draught tube. This is a pipe running from the crankcase (or the valve cover on an overhead valve engine) down to a downwards-facing open end located in the vehicle's slipstream. When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft ...

3. Volkswagen air-cooled engine - Wikipedia

   en.wikipedia.org/wiki/Volkswagen_air-cooled_engine

   The Volkswagen air-cooled engine is an air-cooled, gasoline-fuelled, boxer engine with four horizontally opposed cast-iron cylinders, cast aluminum alloy cylinder heads and pistons, magnesium-alloy crankcase, and forged steel crankshaft and connecting rods.

4. Crankcase - Wikipedia

   en.wikipedia.org/wiki/Crankcase

   A crankcase is the housing in a piston engine that surrounds the crankshaft. In most modern engines, the crankcase is integrated into the engine block. Two-stroke engines typically use a crankcase-compression design, resulting in the fuel/air mixture passing through the crankcase before entering the cylinder(s). This design of the engine does ...

5. Naturally aspirated engine - Wikipedia

   en.wikipedia.org/wiki/Naturally_aspirated_engine

   Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...

   As of 2024, the 'dual injection' system has not been offered in North American markets. Still, VAG has made numerous enhancements to their engine designs such as the positive crankcase ventilation, repositioning injectors and more to lessen the potential that carbon deposits accumulate on intake valves.

7. Vehicle emissions control - Wikipedia

   en.wikipedia.org/wiki/Vehicle_emissions_control

   The first effort at controlling pollution from automobiles was the PCV (positive crankcase ventilation) system. This draws crankcase fumes heavy in unburned hydrocarbons – a precursor to photochemical smog – into the engine's intake tract so they are burned rather than released unburned from the crankcase into the atmosphere. Positive ...
