Chevrolet Orlando
The Chevrolet Orlando () is a three-row compact MPV manufactured by General Motors under the Chevrolet brand from 2010 to 2023. The first-generation model was mainly developed and manufactured by GM Korea, while also assembled in four other countries. Its main markets were South Korea, Europe, Canada, Latin America, and several other Asian countries. It was not marketed in the United States, after GM announced in May 2010 that it would not do so. The second-generation model launched in 2018 is solely built and sold in China by SAIC-GM joint venture, sharing the same platform with the Buick GL6. It also marked the end of Orlando production in South Korea. __TOC__ First generation (J309; 2010) Concept The Orlando concept was unveiled at the 2008 Paris Motor Show and later at the North American International Auto Show#2009, 2009 North American International Auto Show.

Diesel Engine
The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which Combustion, ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to Mechanics, mechanical Compression (physics), compression; thus, the diesel engine is called a compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Introduction Diesel engines work by compressing only air, or air combined with residual combustion gases from the exhaust (known as exhaust gas recirculation, "EGR"). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases air temperature inside the Cylinder (engine), cylinder so that atomised diesel fuel injected into the combustion chamber ignites. The torque a dies ...

GM Ecotec Engine
The GM Ecotec engine, also known by its codename L850, is a family of inline-four engines, displacing between 1.2 and 2.5 litres. Confusingly, the ''Ecotec'' name was also applied to both the Buick V6 engine, Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the General Motors 122 engine, GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan. Generation I The "Ecotec" name was adopted in 1994 for the new generation of Family II engines (2000 in North America) . The name was already used for the Opel GM Family II engine, GM Family 1 engine, Family 1 and ...

GM Family 1 Engine
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall. The engine first appeared in the Opel Kadett D in 1979, and shortly afterwards in its Vauxhall badged sister – the Vauxhall Astra Mk.1 in 1980. Despite this, the previous Opel OHV engine continued to be sold in entry level versions of the Opel Kadett/Astra and Corsa throughout the 1980s. The Family I is informally known as the "small block", since it shares its basic design and architecture with the larger Family II unit (correspondingly known as the "large block"), which covers the mid range and higher engine capacities up to 2400cc. Originally produced at the Aspern engine plant, production was moved to the Szentgotthárd engine plant in Hungary with the introduction of the DOHC versio ...

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.

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a Slant-4 engine, slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer ...

GM Family 0 Engine
The Family 0 is a family of inline piston engines that was developed by Opel, at the time a subsidiary of General Motors. It was developed as a low-displacement engine for use on entry-level subcompact cars from Opel/Vauxhall. These engines feature a light-weight cast-iron semi-closed deck engine block with an aluminum cylinder head. The valvetrain consists of chain-driven hollowcast dual overhead camshafts (DOHC) that actuate 4-valves per cylinder via roller finger followers with hydraulic tappets. These engines also feature a bore spacing and fracture-split connecting rods. Later versions also incorporate a variable length intake manifold (VLIM) and variable valve timing (VVT). Originally debuting as either a straight-3 or straight-4; a I4 variant was added with the introduction of the second generation, replacing the 1.4 L Family 1 engine. The ''Family 0'' engines were produced by Opel Wien in Vienna/ Aspern (Austria), by GM in Bupyeong (Korea) and Flint ( ...

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 ...
