During fishtailing, [2] the rear end of the car skids to one side, which must be offset by the driver counter-steering, which is turning the front wheels in the same direction as the skid, (e.g. left if the rear swings left) [1] and reducing engine power. Over-correction will result in a skid in the opposite direction; hence the name.
Top: Lateral view; the red circles mark the front air dam/splitter and rear diffuser. Bottom: Rear. A diffuser, in an automotive context, is a shaped section of the car rear which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere.
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) that pulls gases out of the crankcase.
Piping diameter that is too large can reduce torque at low RPM and can cause the exhaust system to be lower to the ground, increasing the risk of it being hit and damaged while the car is moving. [10] On cars with two sets of exhaust pipes, a crossover pipe is often used to connect the two pipes. Typical designs of crossover pipes are a ...
After the war, Volkswagen advertised in the US as not boiling over, even though new water-cooled cars no longer boiled over, but the cars sold well. But as air quality awareness rose in the 1960s and laws governing exhaust emissions were passed, unleaded gas replaced leaded gas and leaner fuel mixtures became the norm.
But when you sneeze, you expel air and change up that flow, forcing odorous particles in your nose or throat upward to the olfactory nerve high in the nasal cavity, which transmits information ...
The low-pressure wake behind a group's leading car reduces the aerodynamic resistance on the front of the trailing car, allowing the second car to pull closer. As the second car nears the first, it pushes high-pressure air forward so less fast-moving air hits the lead car's spoiler. The result is less drag for both cars, allowing faster speeds. [3]
Natural gas leaks happen nearly every day in the U.S. — and they can be deadly if they go undetected. A report from a group of Texas environmental nonprofits released in June found around 2,600 ...
