Mazda Z Engine
The Mazda Z-series is a smaller gasoline inline-four engine ranging in displacements from 1.3 L to 1.6 L. They are the evolution of the cast-iron block B-engine. The Z-engine has 16-valves operated by dual overhead camshafts, which are in turn driven by a timing chain (ZJ/Z6/ZY only). The block of the 98-02 Z5, ZM and ZL engine is cast iron same as the earlier B series of engines. Other Z engines have aluminum alloy block and head, with cast-iron cylinder liners. The block features split upper and lower block assembly for added strength and rigidity, special long intake manifold for added torque, S-VT continuous variable valve timing, and a stainless steel 4:1 exhaust header. In 2011, Mazda started to introduce the SkyActiv-G as a new, more economical option for vehicles that were equipped with the Mazda Z-engine. Production of the Z-series halted in 2014, being the last year of the Mazda2, Verisa as well as Mazda3 of their generations. Mazda moved on to the fu ...

Aluminum Alloy
An aluminium alloy ( UK/IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to their low melting points, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', A ...

Japanese Domestic Market
The term "Japanese domestic market" ("JDM") refers to Japan's home market for vehicles and vehicle parts. Japanese owners contend with a strict motor vehicle inspection and grey markets. JDM is also incorrectly used as a term colloquially to refer to cars produced in Japan but sold in other countries. The average age of JDM cars is 8.7 years, ranking 9th in a survey of 30 of the top 50 countries by gross domestic product. According to the Fédération Internationale de l'Automobile, a car in Japan travels a yearly average of over only , less than half the U.S. average of . Japanese domestic market vehicles may differ greatly from the cars that Japanese manufacturers build for export and vehicles derived from the same platforms built in other countries. The Japanese car owner looks more toward innovation than long-term ownership which forces Japanese carmakers to refine new technologies and designs first in domestic vehicles. For instance, the 2003 Honda Inspire featured the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cylinder Head
In a piston engine, the cylinder head sits above the cylinders, forming the roof of the combustion chamber. In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins. In more modern overhead valve and overhead camshaft engines, the head is a more complicated metal block that also contains the inlet and exhaust passages, and often coolant passages, valvetrain components, and fuel injectors. Number of cylinder heads A piston engine typically has one cylinder head per bank of cylinders. Most modern engines with a "straight" (inline) layout today use a single cylinder head that serves all the cylinders. Engines with a "V" layout or "flat" layout typically use two cylinder heads (one for each cylinder bank), however a small number of 'narrow-angle' V engines (such as the Volkswagen VR5 and VR6 engines) use a single cylinder head spanning the two banks. Most radial engines have one head for each cylind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
DOHC
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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mazda Familia
The , also marketed prominently as the Mazda 323, Mazda Protegé and Mazda Allegro, is a small family car that was manufactured by Mazda between 1963 and 2003. The Familia line was replaced by the Mazda3/Axela for 2004. It was marketed as the ''Familia'' in Japan, which means "family" in Latin. For export, earlier models were sold with nameplates including: "800", "1000", "1200", and "1300". In North America, the 1200 was replaced by the Mazda GLC, with newer models becoming "323" and "Protegé". In Europe, all Familias sold after 1977 were called "323". The Familia was also rebranded as the Ford Laser and Ford Meteor in Asia, Oceania, Southern Africa, some Latin American countries and, from 1991, as the Ford Escort and Mercury Tracer in North America. In addition, the Familia name was used as the Mazda Familia Wagon/Van, a badge-engineered version of the Nissan AD wagon (1994–2017) and Toyota Probox (2018–present). Mazda Familias were manufactured in the Hiroshima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
SkyActiv-D
Skyactiv (styled SKYACTIV) is a brand name for a series of automobile technologies developed by Mazda that increase fuel efficiency and engine output. The initial announcement of the Skyactiv technologies included new engines, transmissions, body, and chassis, which appeared in Mazda products from 2011 onwards. The Mazda Sky concept The precursor of Skyactiv, which featured a Mazda Sky-G 2.3-liter direct injection petrol engine, a Mazda Sky-D 2.2-liter diesel engine, a Sky-Drive automatic transmission, a Mazda Kiyora with Sky-G 1.3 engine and Sky-Drive automatic transmission, was unveiled at the 40th Tokyo Motor Show in 2008.

Exhaust Header
In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word ''manifold'' comes from the Old English word ''manigfeald'' (from the Anglo-Saxon ''manig'' anyand ''feald'' old and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold ''supplies'' air ''to'' the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust manifolds known as headers in American English, as extractor manifolds in British and Australian English, and simply as "tubular manifolds" in British English. These consist of individual exhaust headpipes for each cylinder, which then usually converge into one tube called a collector. Headers that do not have collectors are called zoomie headers.

Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

Variable Valve Timing
Variable valve timing (VVT) is the process of altering the timing of a Poppet valve, valve lift event in an internal combustion engine, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stroke cycle, Two-stroke engines use a Two-stroke power valve system, power valve system to get similar results to VVT. Background theory The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber. The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing (variable valve lift), the valve timing is the same for all ...

S-VT
S-VT, or Sequential Valve Timing, is an automobile variable valve timing technology developed by Mazda. S-VT varies the timing of the intake valve A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or Slurry, slurries) by opening, closing, or partially obstructing various passageways. Valves are technically Pip ...s by using hydraulic pressure to rotate the camshaft. S-VT was introduced in 1998 on the ZL-VE engine and is used in the B-, Z-, MZR- and J-families of engines.
