GM High Feature Engine
The GM High Feature engine (also known as the HFV6, and including the 3600 LY7 and derivative LP1) is a family of modern DOHC V6 engines produced by General Motors. The series was introduced in 2004 with the Cadillac CTS and the Holden Commodore (VZ). It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel injection. Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control. Other features include piston oil-jet capability, forged and fillet rolled crankshaft, sinter forged connecting rods, a variable-length intake manifold, twin knock control sensors and coil-on-plug ignition. It was developed by the same international team responsible for the Ecotec, including the Opel engineers responsible for the 54° V6, with involvement with design and development engineering from Ricardo plc. GM's Australian auto division Holden produced a HFV6 engine under the name " Alloytec." Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holden VE Commodore
The Holden Commodore (VE) is a full-size car that was produced from 2006 to 2013 by Holden, the former Australian subsidiary of General Motors. Dubbed Holden's "billion dollar baby", the car was available as the Holden Berlina—the mid-range model—and the Holden Calais, the luxury variant; utility body styles were marketed as the Holden Ute. Succeeding the VZ series, the VE was the first iteration of the fourth generation of the Holden Commodore, a series of automobiles built between 1978 and 2020. Unlike its predecessors, which used Opel-sourced platforms adapted to mechanics and sizes that would suit the local market, the VE was the first Commodore entirely designed and developed by Holden in Australia. To minimise export redevelopment costs, features such as a symmetrical centre console housing a flush-fitting hand brake lever facilitated the conversion to left-hand drive. The VE was internationally badge-engineered as the Chevrolet Lumina, Chevrolet Omega, Bitter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Ignition
A distributor is an electric and mechanical device used in the ignition system of older spark-ignition engines. The distributor's main function is to route electricity from the ignition coil to each spark plug at the correct time. Design A distributor consists of a rotating arm ('rotor') that is attached to the top of a rotating 'distributor shaft'. The rotor constantly receives high-voltage electricity from an ignition coil via brushes at the centre of the rotor. As the rotor spins, its tip passes close to (but does not touch) the output contacts for each cylinder. As the electrified tip passes each output contact, the high-voltage electricity is able to 'jump' across the small gap. This burst of electricity then travels to the spark plug (via high tension leads), where it ignites the air-fuel mixture in the combustion chamber. On most overhead valve engines, the distributor shaft is driven by a gear on the camshaft, often shared with the oil pump; on most overhead camsha ...

VLIM
In internal combustion engines, a variable-length intake manifold (VLIM),variable intake manifold (VIM), or variable intake system (VIS) is an automobile internal combustion engine manifold technology. As the name implies, VLIM/VIM/VIS can vary the length of the intake tract in order to optimise power and torque across the range of engine speed operation, as well as to help provide better fuel efficiency. This effect is often achieved by having two separate intake ports, each controlled by a valve, that open two different manifolds – one with a short path that operates at full engine load, and another with a significantly longer path that operates at lower load. The first patent issued for a variable length intake manifold was published in 1958, US Patent US2835235 by Daimler Benz AG. There are two main effects of variable intake geometry: ;Swirl: Variable geometry can create a beneficial air swirl pattern, or turbulence in the combustion chamber. The swirling helps distribut ...

Connecting Rod
A connecting rod, also called a 'con rod', is the part of a reciprocating engine, piston engine which connects the piston to the crankshaft. Together with the crank (mechanism), crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the Linkage (mechanical), mechanical linkage used by List of Roman wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankshaft
A crankshaft is a mechanical component used in a reciprocating engine, piston engine to convert the reciprocating motion into rotational motion. The crankshaft is a rotating Shaft (mechanical engineering), shaft containing one or more crankpins, that are driven by the pistons via the connecting rods. The crankpins are also called ''rod bearing journals'', and they rotate within the "big end" of the connecting rods. Most modern crankshafts are located in the engine block. They are made from steel or cast iron, using either a forging, casting (metalworking), casting or machining process. Design The crankshaft is located within the engine block and held in place via main bearings which allow the crankshaft to rotate within the block. The up-down motion of each piston is transferred to the crankshaft via connecting rods. A flywheel is often attached to one end of the crankshaft, in order to smoothen the power delivery and reduce vibration. A crankshaft is subjected to enormou ...

Deep Rolling
Deep rolling is a method of cold work deformation and burnishing of internal combustion engine crankshaft journal fillets to increase durability and design safety factors. Compressive residual stresses can be measured below the surface of a deep-rolled fillet. Other types of fillets on shafts or tubes can also benefit from this method. Cast iron crankshafts will experience the most improvement potentially doubling their fatigue life. Typically the crankshaft is machined with under-cut fillets as opposed to tangential radiused for ease of manufacture, although all types can be deep-rolled. Most automakers are currently utilizing this crankshaft technology including: General Motors LLC, Ford Motor Company, and Fiat Chrysler Automobiles (FCA) The North American-based Hegenscheidt-MFD Corporation in Sterling Heights, MI, was established in 1966. Ingersoll CM Systems of Midland, Michigan with Global HQ located in Dalian, China and European based SPMS in Évry, France (established 1974), ...

Electronic Throttle Control
Electronic throttle control (ETC) is an Automotive engineering, automotive technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a Car controls#Throttle control, foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, and sometimes called accelerate-by-wire or throttle-by-wire. Operation A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerato ...

Sequential Multi-port Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol (gasoline) engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while carburetion relies on suction created b ...

Holden Commodore (VZ)
The Holden Commodore (VZ) is a full-size car that was produced by Holden from 2004 to 2006 as a sedan and to 2007 as a wagon and Ute sold alongside the new VE series. It was the fourth and final iteration of the third generation of the Commodore and the last to spawn a coupé variant. Its range continued to include the luxury variants, Holden Berlina (VZ) and Holden Calais (VZ). Overview Released in August 2004, the VZ series was a minor facelift of the previous VY series that featured a new V6 engine in different tune guises. The powerplants included , 3.6-litre '' Alloytec'' V6 engines in place of the older 3.8-litre ''Ecotec'' V6. Other changes to the V6 was the loss of the supercharger that was included in the S models from the VT to VY, this was also dropped with the 3.8-litre and would not be used with the new 3.6. These new ''Alloytec'' DOHC engines have carried on through to the Holden Commodore (VE) which was released in July 2006. A new 5L40-E 5-speed automati ...
