Flat Track
Dirt track racing is a form of motorsport held on clay or dirt surfaced banked oval racetracks. Dirt track racing started in the United States before World War I and became widespread during the 1920s and 1930s using both automobiles and motorcycles, spreading throughout Japan and often running on horse racing tracks. There are a myriad of types of race cars used, from open wheel Sprint cars and Modifieds to stock cars. While open wheel race cars are purpose-built racing vehicles, stock cars (also known as fendered cars) can be either purpose-built race cars or street vehicles that have been modified to varying degrees. There are hundreds of local and regional racetracks throughout the United States and also throughout Japan. The sport is also popular in Canada, Mexico, Argentina, Brazil, Chile, Australia, New Zealand, South Africa and the United Kingdom. Racetrack A dirt track's racing surface may be composed of any soil, although most seasoned dirt racers probably consider ...

Sprint Car Racing
Sprint cars are Open-wheel car, open-wheel race cars, designed primarily for the purpose of running on short Oval track racing, oval, circular dirt track racing, dirt or paved tracks. Historically known simply as "big cars," distinguishing them from "Midget car racing, midget cars," sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa. Sprint cars have very high power-to-weight ratios, with weights of approximately (including the driver) and power outputs of over , which give them a power-to-weight ratio besting that of contemporary Formula One, F1 cars. Typically, they are powered by a naturally aspirated, Methanol fuel, methanol-injected Overhead valve engine, overhead valve American V8 engine with a displacement of 410 cubic inches (6.7L) and capable of engine speeds of 9000 rpm. Depending on the mechanical setup (engine, gearing, shocks, etc.) and the track layout, these cars can achieve speeds in exces ...

Midget Cars
Midget cars, also Speedcars in Australia, is a class of racing cars. The cars are very small, with a very high power-to-weight ratio, and typically use four-cylinder engines. They originated in the United States in the 1930s and are raced on most continents. There is a worldwide tour and national midget tours in the United States, Australia, Argentina and New Zealand. Cars Typically, these four-cylinder-engine cars have to and weigh . The high power and small size of the cars combine to make midget racing quite dangerous; for this reason, modern midget cars are fully equipped with roll cages and other safety features. Some early major midget car manufacturers include Kurtis Kraft (1930s to 1950s) and Solar Midget, Solar (1944–46). Midgets are intended to be driven for races of relatively short distances, usually 2.5 to 25 miles (4 to 40 km). Some events are staged inside arenas, like the Chili Bowl (race), Chili Bowl held in early January at the Tulsa Expo Center in Tu ...

Cam (mechanism)
A cam is a rotating or sliding piece in a linkage (mechanical), mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an Eccentric (mechanism), eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the ''Cam follower, follower'', which is a lever making contact with the cam. A cam timer is similar, and these were widely used for electric machine control (an electromechanical timer in a washing machine being a common example) before the advent of inexpensive electronics, microcontrollers, integrated circuits, programmable logic controllers and digital control. Camshaft The cam can be seen as a device that converts rotational mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Block
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block". However, technically, the block of a modern engine (i.e., multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each element, which were bolted together during engine assembly. Modern en ...

Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Motor
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in which hea ...

Late Model
Late Model stock car racing, also known as late model racing and late models, refers to a type of auto racing that involves purpose-built cars simultaneously racing against each other primarily on oval tracks. This type of racing was early-on characterized by its participants' modification to the engines of post-World War II passenger cars, but the modern day understanding references a class that allows considerable modifications to both the engine and body, yet requires some form of front fender package. Overview As the post WWII auto industry began meeting demand for new cars, auto lots were filling up with the pre-war coupes and sedans. These 1939-1941 cars, "modified" with souped up engines, were finding their way to competitions at racing ovals converted from horse racing or newly carved out in fields. In 1948 NASCAR became one of the first organizations to standardize the rules to ensure equal competition. The rulebook mandated that all cars had to be American made, and ...
