SOHC
An overhead camshaft (OHC) engine is a piston engine where 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 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; however an OHV ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Valve
An overhead valve (OHV) engine, sometimes called a ''pushrod engine'', is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with earlier flathead engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. Some early intake-over-exhaust engines used a hybrid design combining elements of both side-valves and overhead valves. History Predecessors The first internal combustion engines were based on steam engines and therefore used slide valves. This was the case for the first Otto engine, which was first s ...

Toyota Engines
This is a list of piston engines developed, independently or with other car companies, by Toyota Motor Corporation. Engine codes Toyota has produced a wide variety of automobile engines, including four-cylinder and V6 engines. The company follows a naming system for their engines: # The first numeric characters specify the engine block's model (usually differed by displacement) # The next one or two letters specify the engine family # The suffix (separated by a dash) specifies the features of the engine: Note: Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige but it is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: * 2NR-FE ** 2NR – Second model in the NR engine family ** F – Normal cylinder head DOHC ** E – Multi-point fuel injection * 3S-GTE ** 3S – Third model in the S engine fami ...

Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given engine displacement, displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger 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. History Prior to the invention of the turbocharger, forced induction was only possible using mechanically-powered superchargers. Use of superchargers began in 1878, when sev ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toyota Coaster
The is a single-decker minibus produced by Toyota Motor Corporation. It was introduced in 1969, with the second generation introduced in 1982, followed by the third generation in 1993 and the fourth generation in late 2016. In Japan, the Coaster is sold exclusively at ''Toyota Store'' dealerships. Since 1996, the Toyota Coaster is also sold under the name Hino Liesse II. In Japan, the Coaster was formerly produced by Toyota Auto Body at its Yoshiwara plant. In December 2016, after the launching of a revised Coaster, production was transferred to the Honsha plant of a Toyota Auto Body subsidiary, Gifu Auto Body. A number of unlicensed clones of third generation Coasters have been (and are still) made in China, including Jiangnan Motors' JNQ5041/JNQ6601, Joylong Motors' HKL6700, Golden Dragon's XML6700 and Sunlong Bus' SLK6770. History The Toyota Coaster was introduced in 1969 as a 17-passenger minibus using the same running gear as the Toyota Dyna of the time. Early mo ...

Toyota Dyna
The Toyota Dyna is a light to medium-duty cab over truck for commercial use. In the Japanese market, the Dyna is sold alongside its twin called the Toyoace. The Toyoace was a renaming of the Toyopet SKB Truck as a result of a 1956 public competition with 200,000 entries. "Dyna" is short for dynamic. The Dyna was originally available in Japan only at ''Toyota Diesel Store'' locations, then later available at ''Toyota Store'' locations, while the Toyoace twin was available at ''Toyopet Store'' locations. The Dyna was also sold as the Daihatsu Delta and the Hino Dutro. In Japan, its traditional competitors are the Isuzu Elf, the Mitsubishi Fuso Canter and the Nissan Atlas. The former Central Motors produced the Dyna Route Van from April 1957 to June 1967. History RK52 The Toyopet Route Truck RK52 was the contributing platform of the Dyna. A new Toyota Japanese dealership was established to sell the Toyopet Toyoace series SKB called ''Toyopet Store'', which also introduc ...

Toyota Land Cruiser
The (also sometimes spelled as LandCruiser) is a series of four-wheel drive vehicles produced by the Japanese automobile manufacturer Toyota. It is Toyota's longest running series of models. , the sales of the Land Cruiser totalled more than 10 million units worldwide. Production of the first generation of the Land Cruiser began in 1951. The Land Cruiser has been produced in convertible, hardtop, station wagon and cab chassis body styles. The Land Cruiser's reliability and longevity have led to huge popularity, especially in Australia, where it is the best-selling body-on-frame, four-wheel drive vehicle. Toyota also extensively tests the Land Cruiser in the Australian outback considered to be one of the toughest operating environments in both temperature and terrain. In Japan, the Land Cruiser was once exclusive to Toyota Japanese dealerships called '' Toyota Store''. As of 2021, the full-size Land Cruiser was available in many markets. Exceptions include the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter '' tau''. When being referred to as moment of force, it is commonly denoted by . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature t ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called 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). Diesel engines work by compressing only air, or air plus 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 the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inline 6
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 Se ...

Toyota HZ Engine
The Toyota 1HZ is an engine developed by Toyota Motor Corporation for the Toyota Land Cruiser and the Toyota Coaster Bus of 1990. It replaced the previous (2H) heavy duty engine which was being used in older Toyota Land Cruiser models. This engine generates more power and torque than previous diesel Toyota Land Cruiser engine. Despite being 30 years old, the 1HZ still sees use in Landcruiser 70 Series production worldwide with the exception of petrol-only markets and Euro 4 and Australian markets, where the 1GR-FE and 1VD-FTV Turbo-Diesel is supplied respectively. A popular engine in the 80 series Land Cruiser, it replaced the 2H engine in the 80/85 series by 1990. The 1HZ Toyota Landcruiser 4.2 litre (4164 cc) diesel inline 6-cylinder 12-valve SOHC (overhead camshaft) is of the IDI or indirect injection design, and delivers maximum power of 96 kW (129 hp) at 3800 rpm and maximum torque of at 2200 rpm. The 5-cylinder variant of this engine is known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
