Nissan KA Engine
The KA engines were a series of four-stroke inline-four gasoline piston engines manufactured by Nissan, which were offered in 2.0 and 2.4 L. The engines blocks were made of cast-iron, while the cylinder heads were made of aluminum. Despite their large capacity, this motor was not equipped with balance shafts. When used in the passenger cars both versions of the KA24 used a crankshaft girdle, as opposed to individual main bearing caps. In the Nissan Hardbody and Frontier applications a crank girdle was not used. KA20 KA20DE The KA20DE was a DOHC 16-valve engine produced from June 1999 through August 2007. It was mainly used in Japanese Domestic Market commercial vehicles. ;Specifications * Bore × Stroke: * Max power: at 5200 rpm ( Caravan E24/E25, Atlas F23); at 5600 rpm ( Datsun Truck D22) * Max torque: at 2800 rpm (Caravan E24/Atlas F23); at 2800 rpm (Caravan E25); at 3200 rpm (Datsun Truck D22) * Valve Configuration: DOHC, 16 valves * Compre ...

Reciprocating Engine
A reciprocating engine, more often known as a piston engine, is a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is introduced, e ...

Overhead Camshaft
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. ''Single overhead camshaft'' (SOHC) engines have one camshaft per cylinder bank, bank of cylinders. ''Dual overhead camshaft'' (DOHC, also known as "twin-cam") engines have two camshafts per bank. The first production car to use a DOHC engine was built in 1910. Use of DOHC engines slowly increased from the 1940s, leading to many automobiles by the early 2000s using DOHC engines. Design In an OHC engine, the camshaft is located at the top of the engine, above the combustion chamber. This contrasts the earlier overhead valve engine (OHV) and flathead engine configurations, where the camshaft is located down in the engine block. The valves in both OHC and OHV engines are located above the combustion chamber; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nissan Hardbody Truck
The Datsun truck is a compact pickup truck made by Nissan in Japan from 1955 through 1997. It was originally sold under the Datsun brand, but this was switched to Nissan in 1983. It was replaced in 1997 by the Frontier and Navara. In Japan, it was sold only in '' Nissan Bluebird Store'' locations. Predecessors Pre-war The Datsun truck line began with the Type 13 truck of April 1934, and was later used as the basis of the Datsun DC-3 roadster. A series of small trucks based on their passenger car counterparts, the 14T, 15T, and 17T, continued to be built until early 1944. Post-war The 17T was followed by the post-war Datsun 1121 in 1946, which was nearly identical technically but had an extremely simple body made out of simple pressed metal (with almost no chrome) and many body parts made from wood, to enable production in resource-starved early post-war Japan. Early trucks also depended on leftover stocks of pre-war parts. The engine was the Type 7 unit. As the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Bearing
A main bearing is a bearing in a piston engine which holds the crankshaft in place and allows it to rotate within the engine block. The number of main bearings per engine varies between engines, often in accordance with the forces produced by the operation of the engine. Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps. Number of main bearings The number of main bearings is primarily determined by the overall load factor and maximum engine speed. Increasing the number of bearings in an engine will generally increase the size and cost of the engine, but also reduces bending stress and deflection caused by the distance from the crank pins to the nearest bearings. Most engines have at least two main bearings— one at each end of the crankshaft. Additional bearings may be located along the crankshaft, sometimes as many as one bearing per crank pin, as used on many modern diesel engines and petrol engines des ...

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 ...

Balance Shaft
Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in the opposite direction to each other, which generates a net vertical force. The balance shaft was invented and patented by British engineer Frederick W. Lanchester in 1907. It is most commonly used in inline-four and V6 engines used in automobiles and motorcycles. Overview The operating principle of a balance shaft system is that two shafts carrying identical eccentric weights rotate in opposite directions at twice the engine speed. The phasing of the shafts is such that the centrifugal forces produced by the weights cancel the vertical second-order forces (at twice the engine RPM) produced by the engine. The horizontal forces produced by the balance shafts are equal and opposite, and so cancel each other. The balance shafts do not reduce the vibrations experienced by the crankshaft. Applications Two-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...
