Vauxhall Slant-4 Engine
The Vauxhall Slant-4 (or Slant Four) is an inline-four engine, inline four-cylinder petrol automobile, car engine manufactured by Vauxhall Motors. Unveiled in 1966, it was one of the first production overhead camshaft designs to use a Timing belt (camshaft), timing belt to drive the camshaft. The Slant-4 block was used as a development mule for the Lotus 900 series of engines. Vauxhall used the engine in a variety of models until production ended in 1983. History Design The Slant-4 gets its name from the fact that its cylinder (engine), cylinders are inclined at an angle of approximately 45° from vertical. This layout came about because Vauxhall had originally planned to develop a whole family of engines all built on the same production line. There were to be slant-4s and V8s in both petrol and diesel versions, designed under the guidance of Vauxhall's then chief engineer, John Alden. Although a V8 petrol prototype and several 4-cylinder diesel prototypes were built only the 4-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lotus 900 Series
The Lotus 900 series is a family of internal combustion engines designed and built by Lotus Cars of United Kingdom. Successor to the Lotus-Ford Twin Cam, the 900 was the first complete engine developed by Lotus. The engine was built from 1972 to 1999. Background As early as 1964, Lotus recognized the need to find a replacement for the Lotus Twin Cam engine. Colin Chapman issued a brief that listed the features to be required in a new engine, including 'high efficiency, flexibility, torque and smoothness which was suitable for hand assembly'. Unable to find this combination in any existing engine, the company used outside consultants and internal resources to define the characteristics of the next Lotus engine. After having rejected a 120° V6 due to being too wide for Lotus' chassis and a 60° V6 as too tall for the intended bodywork, the engineers determined that a 2-litre inline-four engine was the optimal choice. This future engine would have four valves per cylinder (16 val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Crossflow Cylinder Head
A crossflow cylinder head is a cylinder head that features the intake and exhaust ports on opposite sides. The gases can be thought to flow across the head. This is in contrast to reverse-flow cylinder head designs that have the ports on the same side. Crossflow heads use overhead valves, but these can be actuated either by overhead camshafts, or by a valve-train, which has the camshafts in the cylinder block, and actuates the valves with push rods and rockers.

Allen Key
file:Allen keys.jpg, Hex keys of various sizes file:Inbus-sruby.jpg, Socket head screws of various sizes A hex key (also, hex wrench, Allen key and Allen wrench) is a simple driver for bolts or screws that have heads with ''internal'' hexagonal recesses (sockets). Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly-shaped screw sockets. The rods are bent to 90º, forming two arms of unequal length resembling an "L". The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque. Hex keys are designated with a socket size and are manufactured with tight tolerances. As such, they are commonly sold in kits that include a variety of sizes. Key length typically increases with size, but not necessarily proportionally so. Varian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feeler Gauge
A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. Description They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece. They are flexible enough that, even if they are all on the same hinge, several can be stacked together to gauge intermediate values. It is common to have two sets: one for imperial units (typically measured in thousandths of an inch), and one for metric (typically measured in hundredths of a millimetre) measurements (with intervals of thousandths of an inch and hundredths of a millimetre being roughly in the same order of magnitude). The same device with wires of specific diameter instead of flat blades is used to set the gap in spark plugs to the correct size; this is done by increasing or decreasing the gap until the gauge of the correct size just fits inside the gap. The lengths of steel are sometimes called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw
A screw and a bolt (see '' Differentiation between bolt and screw'' below) are similar types of fastener typically made of metal and characterized by a helical ridge, called a ''male thread'' (external thread). Screws and bolts are used to fasten materials by the engagement of the screw thread with a similar ''female thread'' (internal thread) in a matching part. Screws are often self-threading (also known as self-tapping) where the thread cuts into the material when the screw is turned, creating an internal thread that helps pull fastened materials together and prevents pull-out. There are many screws for a variety of materials; materials commonly fastened by screws include wood, sheet metal, and plastic. Explanation A screw is a combination of simple machines: it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts as a wedge as it pushes into the fastened material, and th ...

Poppet Valve
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the New Castle and Frenchtown Turnpike and Railroad Company, Newcastle and Frenchtown Railroad. Young had patented his idea, but the 1836 U.S. Patent Offic ...

Glas 1004
The Glas 1004 is a small two-door, four-seater automobile produced by Hans Glas GmbH at Dingolfing. It was first exhibited in public, in coupé form, at the Frankfurt Motor Show in September 1961. Volume production of the 1004 coupé started in May 1962, and in January 1963 saloon/sedan and cabriolet versions joined the range along with the more powerful Glas 1204. September 1965 saw a yet more powerful variant, the Glas 1304. In September 1966, a fastback Kombilimousine (estate) was added. The 04s were produced at least until December 1967, and new cars were listed for sale through much of 1968. Origins In 1960 the company's research workshop came up with an engine that used an unconventional camshaft drive. Product developer Leonhard Ischinger, who had joined Glas from BMW, had produced a four-cylinder OHC engine with valve gear driven using a toothed rubber cam-belt, which at that time was a novel idea. The 992 cc engine provided a maximum output of 31 kW (42 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pontiac Straight-6 Engine
The Pontiac straight-6 engine is a family of inline-six cylinder automobile engines produced by the Pontiac Division of General Motors Corporation in numerous versions beginning in 1926. "Split Head" Six 186 In the 1920s Oakland Motor Car engineers designed an all new engine for their "companion" make, the Pontiac, that was introduced in 1926. It was a side-valve design with a one piece cast iron block with three main bearings. An unusual feature was that it had two separate cylinder heads that each covered three cylinders. The ignition distributor was mounted on top of the block in the gap between the heads. This engine was also used in GMC's T-10 and T-11 (their two lightest trucks) beginning in 1928. Development of the engine shared characteristics with the Oldsmobile Straight-6 engine, as GM worked together to develop the engine for Pontiac combined with the resources of GM-Northway Motor and Manufacturing Division. This engine displaced with a bore and stroke of and was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
