Why are air-cooled engines in the rear?

Finally, a rear-mounted engine has empty air (often at a lower pressure) behind it when moving, allowing more efficient cooling for air-cooled vehicles (more of which have been RR than liquid-cooled, such as the Volkswagen Beetle, and one of the few production air-cooled turbocharged cars, the Porsche 930).

What car has an air-cooled engine?

The air-cooled engine was the stuff of legend, powering the Porsche 911 and VW Beetle (the real Beetle, not the ersatz New Beetle) to enduring fame in automotive history. And then it was gone. The last 911 powered this way vanished after the 1998 model year, while the air-cooled Beetle soldiered on until 2003.

Why do air-cooled engines sound different?

A distinctive characteristic of air-cooled engines is the noise. Due to the lack of water ways throughout the block and head to aid sound insulation, the engines can often sound louder than their water-cooled brethren.

Can you turbo an air-cooled engine?

Turbocharging, without a doubt, provides the biggest increase in performance for your aircooled VW. Power gains of +50\% to over +100\% are possible with a properly setup turbo system. Through the use of turbocharging, we have extracted over 450hp from our VW Type 4 performance engines.

Can you let an air cooled engine idle?

Air cooled bikes do not have a limited range. With enough air flow, air cooled engines will not overheat and can be driven for hundreds of miles (or kilometers). However, if traffic is stagnant and you have to sit idle for some time, then air cooled bikes will tend to overheat.

What are air-cooled condensers?

An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC.

How do automotive air-cooled engines work?

Automotive air-cooled engines are actually cooled by both air and oil. Basic cooling is provided by generous fins on the cylinders and cylinder heads which expose as much surface area as possible to the cooling air forced across them by an engine-driven fan. Located in the airstream is a heat exchanger to control the temperature of the engine oil.

Are there any air cooled cars with the engine in front?

Yes, as all the answers here have shown, there are certainly air-cooled cars with the engine in front. This VW Gol was one of my favorite models and was introduced in 1980 in Brazil, to replace VW do Brasil’s best selling rear-engined car (after the Beetle of course) VW Brasilia. Not bad, eh?

Why are cars with air-cooled engines more polluting?

Because their cooling systems are generally always “on,” even when stone cold, air-cooled engines tend to run cold longer at startup. That spews more emissions from partially burned fuel, which is a great way to get on the wrong side of the US EPA in the 21st century.

What is the difference between water cooled and air cooled engines?

Water-cooled engines always have a constant supply of hot water and it is easy enough to convert this into hot air. Air-cooled engines usually have an independent heater or harness the heat of the exhaust system. Some older models have heating systems that combine both of these methods.
