Diagram of a car undergoing fishtailing. Video of a car fishtailing or drifting on the street of Riia maantee in Tartu, Estonia (December 2021) Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low-friction surfaces (sand, gravel, rain, snow, ice, etc.).
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.
The Turbo-back (or turbo back) is part of the exhaust system from the outlet of a turbocharger to the final vent to open air. Turbo-back systems are generally produced as aftermarket performance systems for cars with turbochargers. Some turbo-back (and header-back) systems replace stock catalytic converters, while others have less flow restriction.
Whistle tips, also referred to as whistler tips, or whistlers, are modified vehicle exhaust pipes that generate a whistling sound during the operation of a motor vehicle that can often be heard up to a mile away. [1] The whistle tip is a small metal plate with a central hole that is welded into the inner tip of the exhaust pipe.
The layout of a 4-2-1 system is as follows: four pipes (primary) come off the cylinder head, and merge into two pipes (secondary), which in turn finally link up to form one collector pipe. [ 2 ] Compared with a 4-1 exhaust system, a 4-2-1 often produces more power at mid-range engine speeds (RPM), while a 4-1 exhaust produces more power at high ...
When the descending piston first exposes the exhaust port on the cylinder wall, the exhaust flows out powerfully due to its pressure (without assistance from the expansion chamber) so the diameter/area over the length of the first portion of the pipe is constant or near constant with a divergence of 0 to 2 degrees which preserves wave energy ...
An acoustic pipe, such as an organ pipe, marimba, or flute resonates at a specific pitch or frequency. Longer pipes resonate at lower frequencies, producing lower-pitched sounds. The details of acoustic resonance are taught in many elementary physics classes. In an ideal tube, the wavelength of the sound produced is directly proportional to the ...
Roadway noise is the most prevalent form of environmental noise.Pictured: São Paulo, Brazil. Roadway noise is the collective sound energy emanating from motor vehicles.It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements.
