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 a loose indicator of the power 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 engine. The formula is: : \text = \text \times \frac \times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wastegate
A wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system.Robson, D. (2018). Aircraft General Knowledge. Aviation Theory Centre Pty Ltd. . Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger. One advantage of installing a remote mount wastegate to a free-float (or non-WG) turbo includes allowance for a smaller A/R turbine housing, resulting in less lag time before the turbo begins to spool and create boost. Wastegate types External An external wastegate is a separate self-contained mechanism typically used with turbochargers that do not have internal wastegates. An external wastegate requires a specially constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate may be pa ...

Exhaust Manifold
In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word '' manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' old and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ''supplies'' air ''to'' the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in American English, as extractor manifolds in British and Australian English,''The Design and Tuning of Competition Engines'', Philip H. Smith, pp. 137–138 and simply as "tubular manifolds" in British English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Pan
A sump is a low space that collects often undesirable liquids such as water or chemicals. A sump can also be an infiltration basin used to manage surface runoff water and recharge underground aquifers. Sump can also refer to an area in a cave where an underground flow of water exits the cave into the earth. Examples One common example of a sump is the lowest point in a basement, into which flows water that seeps in from outside. If this is a regular problem, a sump pump that moves the water outside of the house may be used. Another example is the oil pan of an engine. The oil is used to lubricate the engine's moving parts and it pools in a reservoir known as its sump, at the bottom of the engine. Use of a sump requires the engine to be mounted slightly higher to make space for it. Often though, oil in the sump can slosh during hard cornering, starving the oil pump. For these reasons, racing motorcycles and piston aircraft engines are "dry sumped" using scavenge pumps and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Head
In an internal combustion engine, the cylinder head (often abbreviated to simply "head") sits above the cylinders and forms the roof of the combustion chamber. In sidevalve engines, the head is a simple sheet of metal; whereas in more modern overhead valve and overhead camshaft engines, the cylinder head is a more complicated block often containing inlet and exhaust passages, coolant passages, valves, camshafts, spark plugs and fuel injectors. Most straight engines have a single cylinder head shared by all of the cylinders and most V engines have two cylinder heads (one per bank of cylinders). Design A summary of engine designs is shown below, in chronological order for automobile usage. Sidevalve engines In a flathead (''sidevalve'') engine, all of the valvetrain components are contained within the block, therefore the head is usually a simple sheet of metal bolted to the top of the engine block. Sidevalve engines were once universal in automobiles but are n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder Bore
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. Steam locomotive The term bore also applies to the cylinder of a steam locomotive or steam engine. See also * Bore pitch * Compression ratio * 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 a loose indicator of the ... References {{Steam engine configurations Engine technology ...

Ward's 10 Best Engines
10 of the World's best engines is an annual list of the ten ''"''best''"'' automobile engines available in the U.S. market, that are selected by '' Ward's AutoWorld'' magazine. The list was started in 1994 for Model Year 1995, and has been drawn every year since then, published at the end of the preceding year. Engines must be available in regular-production vehicles on sale in the U.S. market no later than the first quarter of the year. Eligibility has also been based on availability in a vehicle below a base price limit, which increased progressively from for the 1995 list up to for the 2020 list; this limit was eliminated for future competitions following the announcement of the 2020 winners. During a 2-month testing period, Wards editors evaluate each engine according to a number of objective and subjective criteria in everyday driving situations – there is no instrumented testing. The selection takes into account power and torque output, noise, vibration and harshness (NV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infiniti Q60
The Infiniti Q60 is a 2-door sport luxury coupe manufactured by Japanese automaker Infiniti. It is the successor to the Infiniti G coupe and convertible. The Q60 nameplate was first used as a rebranding of Infiniti G coupes. A new version was introduced in early 2016, as a 2017 model. First generation (2013; V36) The first-generation Infiniti Q60 was based on the fourth generation (V36) G Coupe. This came about when Infiniti former president Johan de Nysschen cited the need for "a new identity and direction to promote consumer familiarity with our model range as we expand the portfolio." Beginning in 2014, all passenger cars would be "Q" followed by a two-digit number. Those numbers would correspond to the vehicle’s position in the Infiniti hierarchy. Second generation (2016; V37) The second-generation Infiniti Q60 was unveiled at the 2015 North American International Auto Show as a concept. A year later, Infiniti unveiled the production version at the 2016 North Ame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infiniti Q50
The Infiniti Q50 is a compact executive car manufactured by Nissan for its luxury brand, Infiniti. Replacing the G/Q40 sedan, it debuted at the 2013 North American International Auto Show and went on sale in North America in the third quarter 2013 and in Europe in fourth quarter 2013. It is the export model of the Japanese domestic market's V37 Nissan Skyline. The design of the Q50 continues to follow the designs first shown by the 2009 Infiniti Essence concept and the production 2011 Infiniti M. The Q50 is also the first instance of a hybrid model in Infiniti's entry-level model but was later removed for the 2019 model year. First generation Q50 sedan (2013–) The design was based on Infiniti Essence (crescent-cut C-pillar, deep body section, asymmetrical cabin layout, interior finishes) and Infiniti Etherea (headlights, three-dimensional double-arch grille, interior finishes).

Infiniti
is the luxury vehicle division of the Japanese automaker Nissan. Infiniti officially started selling vehicles on November 8, 1989, in North America. The marketing network for Infiniti-branded vehicles included dealers in over 50 countries in the 2010s. As of 2020, there were 25 markets served by new car dealers. The main markets are North America, China, and Middle East. According to the company, the Infiniti badge has a double meaning, as stylized representations of both a road extending into the horizon and of Mount Fuji, reflecting its Japanese origins. History The beginning The Infiniti brand was introduced in the United States in 1989 to target the premium vehicle segments in the United States that would not have otherwise fit in with Nissan's more mainstream image, and partially influenced by the Plaza Accord of 1985. The brand was created around the same time that Japanese rivals Toyota and Honda developed their Lexus and Acura premium brands, respectively. The Japa ...

Le Mans
Le Mans (, ) is a city in northwestern France on the Sarthe River where it meets the Huisne. Traditionally the capital of the province of Maine, it is now the capital of the Sarthe department and the seat of the Roman Catholic diocese of Le Mans. Le Mans is a part of the Pays de la Loire region. Its inhabitants are called ''Manceaux'' (male) and ''Mancelles'' (female). Since 1923, the city has hosted the 24 Hours of Le Mans, the world's oldest active endurance sports car race. History First mentioned by Claudius Ptolemy, the Roman city ''Vindinium'' was the capital of the Aulerci, a sub tribe of the Aedui. Le Mans is also known as ''Civitas Cenomanorum'' (City of the Cenomani), or ''Cenomanus''. Their city, seized by the Romans in 47 BC, was within the ancient Roman province of Gallia Lugdunensis. A 3rd-century amphitheatre is still visible. The '' thermae'' were demolished during the crisis of the third century when workers were mobilized to build the city's defensi ...
