Alfa Romeo 690T Engine
The Alfa Romeo 690T is a twin-turbocharged, direct injected, 90° V6 petrol engine designed and produced by Alfa Romeo since 2015. It is used in the high-performance Giulia Quadrifoglio and Stelvio Quadrifoglio models and is manufactured at the Alfa Romeo Termoli engine plant. Description The 690T is often considered to be the Ferrari F154 engine with two less cylinders, but in fact it is a completely new engine developed by the same engineer, Gianluca Pivetti. Specification similarities that Alfa knew worked well reduced the development time. This 2.9-litre V6 uses single-scroll rather than twin-scroll turbos, which produce of boost pressure. Alfa also added mechanical cylinder deactivation to the right bank for increased highway fuel efficiency. The 90-degree V6 engine's crankshaft has three crankpins 120 degrees apart, each with two connecting rods mounted side by side. This configuration results in uneven firing at 90 and 150 degrees of each rotation, but for each cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wet Sump
Within piston engines, a wet sump is part of a lubrication system whereby the crankcase sump is used as an integral oil reservoir. An alternative system is the dry sump, whereby oil is pumped from a shallow sump into an external reservoir.Wet sump and dry sump compared - https://www.knowyourparts.com/technical-resources/engine/oil-system-differences/#:~:text=Dry%20Oil%20Systems%20Wet%20sump%20systems%20store%20the,is%20used%20to%20pump%20oil%20from%20the%20motor. Piston engines are lubricated by oil which is pumped into various bearings, and thereafter allowed to drain to the base of the engine under gravity. In most production automobiles and motorcycles, which use a wet sump system, the oil is collected in a capacity pan at the base of the engine, known as the sump or oil pan, where it is pumped back up to the bearings by the internal oil pump. A wet sump offers the advantage of a simple design, using a single pump and no external reservoir. Since the sump is internal, t ...

Fuel Efficiency
Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical energy, chemical potential energy contained in a carrier (fuel) into kinetic energy or Mechanical work, work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as Industrial sector, industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency in transportation, energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of Motor fuel, fuel consumed. It is dependent on several factors including engine efficiency, transmission (mechanics), transmission design, and tire design. In ...

Cylinder Deactivation
Variable displacement is an automobile engine technology that allows the engine displacement to change, usually by deactivating cylinders, for improved fuel economy. The technology is primarily used in large multi-cylinder engines. Many automobile manufacturers have adopted this technology as of 2005, although the concept has existed for some time prior to this. Theory of operation Cylinder deactivation is used to reduce the fuel consumption and emissions of an internal combustion engine during light-load operation. In typical light-load driving the driver uses only around 30 percent of an engine’s maximum power. In these conditions, the throttle valve is nearly closed, and the engine needs to work to draw air. This causes an inefficiency known as pumping loss. Some large capacity engines need to be throttled so much at light load that the cylinder pressure at top dead centre is approximately half that of a small 4-cylinder engine. Low cylinder pressure results in lower fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrari F154 Engine
The Ferrari F154 is a family of modular twin-turbocharged, direct injected V8 petrol engines designed and produced by Ferrari since 2013. It is a replacement for the naturally aspirated ''Ferrari-Maserati'' F136 V8 family on both Maserati and Ferrari cars. They are the first turbocharged Ferrari road engines since the 1987 2.9-litre ''F120A'' V8 of the Ferrari F40. Description The F154 V8 engines have a 90° angle between the cylinder banks, aluminium block and heads. The forced induction system uses two parallel twin-scroll water-cooled turbochargers supplied by IHI and two air-to-air intercoolers. The valvetrain consists of 4 valves per cylinder actuated through roller finger followers by two overhead camshafts per bank; the timing chain is located on the flywheel side. All Ferrari versions feature gasoline direct injection and continuously variable valve timing on both intake and exhaust side. The Ferrari version of the engine has a flatplane crankshaft and dry sump lu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termoli
Termoli ( Molisano: ''Térmëlë'') is a ''comune'' (municipality) on the south Adriatic coast of Italy, in the province of Campobasso, region of Molise. It has a population of around 32,000, having expanded quickly after World War II, and it is a local resort town known for its beaches and old fortifications. Once it was known only as a fishing port, but in the new millennium it is a favourite resort for Italian families. Termoli contains the only port of the Molise region. There is also a strong competition (especially in the world of sport) with the Campobasso province, in fact some of the "termolesi" (the name of the people that lives in Termoli) like to say that Termoli is province-less ("Termoli senza provincia"). Geography Location Termoli is located in centre-south of Italy, on the Adriatic Coast of Molise Region. The original settlement developed on the promontory where now there's the ancient village, featured by old white and colorful fisherman houses, narrow streets, ...

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Twin-turbo
Twin-turbo is a type of turbo layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. The ga70 1ggte was the first inline 6 twin turbo in the world. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel In a parallel configuration, two equally-sized turbochargers each receive half of the exhaust gases. Some designs combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
