Compression Release Engine Brake
A compression release engine brake, compression brake, or decompression brake is an engine braking mechanism installed on some diesel engines. When activated, it opens exhaust valves to the cylinders, right before the compression stroke ends, releasing the compressed gas trapped in the cylinders. The compression followed by the "wasteful" release consumes great amount of energy, effectively slowing the vehicle. Clessie Cummins was granted a patent for the engine compression brake in 1965, and the first company to manufacture them was Jacobs Vehicle Systems. Therefore, the brakes are commonly known as Jake brakes. Function When the driver releases the accelerator on a moving vehicle powered by an internal combustion engine, the vehicle's forward momentum continues to turn the engine's crankshaft. Most diesel engines do not have a throttle body, so regardless of the throttle setting, air is always drawn into the cylinders (excluding the valve fitted to certain diesels, such ...

Throttle
A throttle is a mechanism by which fluid flow is managed by construction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term ''throttle'' has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a ''throttle'' (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft. For a steam locomotive, the valve which controls the steam is known as the regulator. Internal combustion engines In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. For a gasoline engine, the throttle most commonly regulates the amount of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate Highway System
The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly known as the Interstate Highway System, or the Eisenhower Interstate System, is a network of controlled-access highways that forms part of the National Highway System (United States), National Highway System in the United States. The system extends throughout the contiguous United States and has routes in Hawaii, Alaska, and Puerto Rico. In the 20th century, the United States Congress began funding roadways through the Federal Aid Road Act of 1916, and started an effort to construct a national road grid with the passage of the Federal Aid Highway Act of 1921. In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were funded and maintained by U.S. states, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane free ...

Ohio County Government
Ohio county government is the structure of official managerial and legal bodies of the List of Ohio counties, counties of Ohio, USA. It is marked by a loose organization and a diffusion of power, the basic framework not having been changed since the nineteenth century. The Ohio Constitution allows counties to set up a charter government as many cities and villages do, but only Summit County, Ohio, Summit and Cuyahoga County, Ohio, Cuyahoga counties have done so. Counties operating under a constitutional government do not possess Home Rule in the United States, home rule powers and can do only what has been expressly authorized by the Ohio General Assembly. However, Article X of the Ohio Constitution gives county government benefits similar to those conferred on cities and villages under the home rule amendments of 1912. Officials Eighty-six of Ohio's 88 counties (all except Summit County, Ohio, Summit as of 1981 and Cuyahoga County, Ohio, Cuyahoga as of 2011) have the followi ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

Muffler
A muffler (North American and Australian English) or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an automobile. Operation Mufflers are installed within the exhaust system of most internal combustion engines. Mufflers are engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting. Sound reduction techniques used in mufflers include: reactive silencing, resistive silencing, absorptive silencing, and shell damping. The noise of the hot exhaust gas exiting the engine can be abated by a series of passages and chambers lined with roving fiberglass insulation and/or resonating chambers harmonically tuned to cause destructive interference, wherein opposite sound waves cancel each other out. The operation of an internal combustion engine produces distinct pulses of exhau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fine (penalty)
A fine or mulct (the latter synonym typically used in Civil law (common law), civil law) is a penalty of money that a court of law or other authority decides has to be paid as punishment for a crime or other Offense (law), offense. The amount of a fine can be determined case by case, but it is often announced in advance. The most usual use of the term is for financial punishments for the commission of crimes, especially minor crimes, or as the settlement (law), settlement of a Claim (legal), claim. One typical example of a fine is money paid for violations of traffic laws. In English law, English common law, relatively Standard scale, small fines are used either in place of or alongside community service orders for low-level criminal offences. More considerable fines are also given independently or alongside shorter prison sentences when the judge or magistrate considers a large amount of retribution is necessary, but there is unlikely to be a significant danger to the public. ...

Jackhammer
A jackhammer (pneumatic drill or demolition hammer in British English) is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. It was invented by William McReavy, who then sold the patent to Charles Brady King. Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete. A jackhammer operates by driving an ''internal'' hammer up and down. The hammer is first driven down to strike the chisel and then back up to return the hammer to the original position to repeat the cycle. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. It is generally used like a hammer to break the hard surface or rock in construction works and it is not considered under earth-moving equipment, al ...
