Tatra Beta
The Tatra Beta was an electric car with about 100 cars produced, using nickel-cadmium batteries This electric car was originally created by Å koda ELCAR Ejpovice, and they were also initially manufactured under the Å KODA brand. At that time, the production was directly connected to the production of the Å koda electric car ELTRA, derived from the Å koda Favorit. The car was produced from 1994 to 1999, and had parts taken from the 120L (front turn signals and headlights) and Favorit (chassis, glass, mirrors, handles, locks and interior) and from the Å koda Pick-UP (rear combination lamps). In 1996 the petrol version with Å koda's 1.3 engines also started to be produced. The original electric drive provided an asynchronous electric motor with maximum power of 40 kW, was powered via a frequency converter from a set of 30 pieces of Ni-Cd batteries. SAFT batteries type STM after 6V had a capacity of 100 Ah. Vehicle with they reached a speed of 110 km / h and covered 120 km per charge. ...

Hyundai Alpha Engine
The Hyundai Alpha series is a multi-valve gasoline inline four-cylinder engine family comprising 1.3, 1.4, 1.5, and 1.6L naturally aspirated versions and a 1.5L turbocharged version. Introduced in 1992, this was Hyundai's first engine designed entirely in-house and was the first indigenous South Korean engine design. Design objectives were to provide high performance and good fuel economy with excellent durability at a reasonable cost. The first Alpha series engine developed and marketed was a 1.5L SOHC 12-valve inline-four. It was naturally aspirated and debuted in the 1992 Hyundai Scoupe. A 1.3L version debuted later in the Hyundai Accent. A dual overhead camshaft (DOHC), four valve per cylinder version later debuted in the 1996 Hyundai Accent GT. A strengthened block, an eight-counterweight crankshaft, and hydraulic engine mounts were added in 2000 to reduce NVH (noise, vibration and harshness). The 1.6L Alpha II debuted in 2001, eventually replacing the 1.3L and 1.5L. It wa ...

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 en ...

Multivalve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which can redu ...

Straight-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Å koda Favorit
Å koda Favorit is a model name that the Czechoslovakia, Czechoslovak (and now Czech Republic, Czech) car maker Å koda Auto has used for two series of car models. The first series was the Type 904 which was a 1.8 litre car built from 1936 to 1939, and its successor the Type 923 which was a 2.1 litre car built from 1938 to 1941. These two models had little commercial success and were discontinued after only 223 examples had been built. After their commercial failure, Å koda did not use the Favorit model name again for 46 years. The second series is the Type 781 range of Supermini, supermini cars that was made from 1987 to 1995. It was Å koda's first car to follow the European trend of locating the front-engine design, engine at the front, mounted transverse engine, transversely, and was also their first car to use front-wheel drive. The Favorit was premiered in July 1987 at the Brno Engineering Fair. History This latest Favorit eventually succeeded the ageing rear-engine design ...

Hyundai Accent
The Hyundai Accent ( ko, 현대 엑센트), or Hyundai Verna (현대 베르나) is a subcompact car produced by Hyundai. In Australia, the first generation models carried over the Hyundai Excel name used by the Accent's predecessor. The Accent was replaced in 2000 by the Hyundai Verna in South Korea, although most international markets, including the US, retained the "Accent" name. The "Accent" name is an abbreviation of ''Advanced Compact Car of Epoch-making New Technology''. The Accent is produced for the Chinese market by Beijing Hyundai Co., a joint venture with Beijing Automotive Industry Corp. For the Russian market it was assembled by the TagAZ plant in Taganrog until 2011, and since 2011 it is assembled by the HMMR plant in Saint Petersburg and sold under the new name Hyundai Solaris. In Mexico, the Accent was marketed until 2014 by Chrysler as the Dodge Attitude, previously known as the Verna by Dodge. In Venezuela, Chrysler marketed these models as the Dodge Brisa ...
