The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1981. Available in a wide range of cubic capacities ranging from 1598 to 2405 cc , it simultaneously replaced the Opel CIH and Vauxhall Slant-4 engines, and was GM Europe 's core mid-sized powerplant design for much of the 1980s, and provided the basis for the later Ecotec series of engines in the 1990s.
92-462: The Family II shares its basic design and architecture with the smaller Family I engine (which covered capacities from 1.0 to 1.6 litres) - and for this reason the Family I and Family II engines are also known informally as the "small block" and "big block", respectively - although the 1.6 L capacity was available in either type depending on its fuelling system. The engine also spawned two diesel variants,
184-401: A cast iron engine block . GM do Brasil versions were also capable of running on ethanol. These engines share their basic design with the larger Family II engine – for this reason some consider the Family I and Family II to be the same series and instead use the terms 'small block' and 'large block' to distinguish between the two. Over the years there has been overlap between the two types as
276-493: A distributorless ignition system , namely Bosch Motronic 2.8. The last version was called C20LN (Low Noise) and has a stronger engine block. In 1991, the Coscast cylinder head was replaced with the GM cylinder head which was manufactured by Kolben-Schmidt. One of the most prominently recognized qualities of the Coscast head is its inherent lack of porosity; this was achieved by pumping
368-640: A square 86 mm (3.4 in) bore and stroke. They also feature fuel injection , an aluminum crossflow cylinder head with a belt-driven overhead camshaft, electronic ignition , a six-bolt flywheel , and a 6,400 rpm redline . Originally, developed by Opel , these engines have been used in Brazilian market vehicles, Korean market vehicles and North American market vehicles; with the first versions appearing in 1981, although did not start appearing in European Opel/Vauxhall models until 1986 - firstly in
460-461: A toothed belt driven valvetrain, a cast-iron engine block and an aluminum cylinder head . Most models feature Euro III -compliancy, and the 1.4 L (1399 cc) and 1.6 L (1598cc) versions employ variable intake geometry. With the release of Chevrolet Cruze , the factory has been converted to produce the Ecotec Family 1 Gen III block. Applications: The E-TEC II 16V is an updated version of

#17330861241961104-517: A catalytic converter and a lambda or oxygen sensor – this requirement permitted the fitment of the Bosch Motronic 2.5 engine management system. Engine power output dropped to 150 bhp. Vauxhall complied with the new emission controls in 1988, although the legislation wasn't law until 1991. Vehicles fitted with the C20XE engine produced before 1991 can have their catalytic converter legally removed, and
1196-463: A change to the lubrication specification eventually solved the issue. Another known issue on the Family II was for the water pump to become jammed into its mounting due to corrosion if the engine was run with no antifreeze; the pump is mounted into an eccentric shaped aperture so it can also function as the timing belt tensioner. If the pump cannot turn then the belt cannot be tensioned. Later versions of
1288-496: A longitudinal installation (for rear-wheel drive) have one major design difference from their transverse mounted counterparts - the distributor is driven by a small drivebelt from the camshaft timing sprocket rather than directly off the transmission end of the camshaft, which on the Manta B and Rekord E2 (both older vehicles that had originally been designed around the CIH engine) would have meant
1380-468: A low optimum specific fuel consumption of 232 g/kWh which is equivalent to a maximum efficiency of 37%; a better efficiency than some of the diesel engines that were available at the time of its release. The valves are set at 46° and are accompanied by pistons with shallow valve pockets – thereby eliminating the need for a shorter connecting rod hence, allowing a suitable compression ratio to be achieved. Long spark plugs are used and positioned concentric to
1472-412: A narrower bore version of the existing 1.3-litre version, displacing 1,195 cc (72.9 cu in), replaced the original design. This was also available with single-point fuel injection and with catalytic converters. The 1,297 cc (79.1 cu in) version has a 75.0 mm (2.95 in) bore and a 73.4 mm (2.89 in) stroke. The 1,389 cc (84.8 cu in) version has
1564-561: A new cylinder head design. This was the first engine in this family, featuring a Lotus -developed 16-valve cylinder head and a cast-iron cylinder block which was essentially the same as in Opel's 8-valve engines. C16XE was available only in Corsa GSi , model years 1993 and 1994. C16XE was not yet badged Ecotec, and for later model Corsas and Opel Tigras it was replaced with X16XE Ecotec engine. The main difference between C16XE and X16XE Ecotec
1656-480: A pair of Welch plugs be pressed in at either end of the head. In situations where a complete C20XE is still fitted to a vehicle, the presence of Welch plugs (or lack of) has proven to be the sole means of differentiating between GM and Coscast heads. A reinforced version of the GM head became available in the later years of the C20XE ; however, these reinforcements meant that it had smaller inlet/exhaust channels than
1748-486: A porous head have a tendency to vary. Many C20XE operators have described the symptom as a curry-like residue or in more severe cases, a thick brown sludge which may overcome the entire cooling system. In such instances, engine oil will readily react with the sulfur in rubber components, hence quickly degrading coolant pipes and hoses to the point of failure. During the porous head debacle, GM faced bankruptcy – therefore dealers failed to recall affected models. Due in part, to

Tuned by Spiess, an F3 grade C20XE is easily capable of producing 250 bhp (190 kW) in its naturally aspirated form. Many aftermarket tuners have further developed
5980-454: The engine were equipped with a separate jockey pulley to combat the issue. The 1.6-liter iteration (1,598 cc or 97.5 cu in) has an 80.0 mm (3.15 in) bore and a 79.5 mm (3.13 in) stroke. Opel began production of the 1.6-liter engine in 1980. A diesel fueled version also became available. The diesel produced 54 PS (40 kW) at 4600 rpm and 70.8 lb⋅ft (96.0 N⋅m) of torque at 2400 rpm. It also had
6072-407: The engine's immense prominence and demand, many businesses now specialize in the repair of porous GM C20XE/LET heads – by either sleeving the affected gallery or by injecting a polymer based substance into the porous region. Reportedly, a small number of total GM C20XE cylinder heads ever exhibited significant symptoms of porosity. The C20XE has seen extensive use in motorsport. Typical uses for
6164-455: The first departments moved to the new center, while the remaining departments followed in 2015. In 2006, Bosch acquired Telex Communications and Electro-Voice . In 2009, Bosch invested about 3.6 billion Euro in development and research. Approximately 3900 patents are published per year. In addition to increasing energy efficiency by employing renewable energies, the company plans to invest in new areas such as biomedical engineering . China
6256-777: The gas appliances production from Junkers & Co. in 1932, as a part of a diversification strategy. In 1932, the company developed its first electric drill and presented its first car radio. In 1933, Bosch presented its first electric refrigerator for private households. In late 1933 negotiations between Robert Bosch AG and the Nazi Party began on relocating parts of armaments production to Germany's interior. Bosch founded two such alternative plants in 1935 and 1937: Dreilinden Maschinenbau GmbH in Kleinmachnow near Berlin and Elektro- und Feinmechanische Industrie GmbH (later Trillke-Werke GmbH) in Hildesheim . Both plants were used exclusively for armament production. These "shadow factories" were built under great secrecy and in close cooperation with
6348-437: The heads from this lineup are supposed to flow appreciablу better than their Lotus successors. The 20XE came into production in 1987. The engine was designed by Cosworth, UK. The engine was originally intended for race application, hence Cosworth 's involvement. At the time of its launch, this engine was something of a milestone unit in Europe and was widely used in motorsport in many specialist race versions. The engine had
6440-502: The last years of the war, no new German tank ever drove without the starter elements from the Bosch factory in Hildesheim. Bosch also had a monopoly position in the outfitting of German Luftwaffe aircraft. During the war, production was further decentralized, Bosch produced in an ever larger number of factories, and relocated parts of its production to 213 plants in more than 100 locations. In 2001, Bosch acquired Mannesmann Rexroth AG , which they later renamed to Bosch Rexroth AG . In
6532-441: The liquid metal into the mold rather than pouring it, hence, minimizing the presence of tiny air bubbles that usually form during the standard casting process. The Coscast head can be identified by a Coscast logo which is stamped under the 3rd exhaust port and a ridge on the head under the distributor. The GM head was a poured casting, and featured a slightly different oil/water gallery design. These design changes required that
6624-554: The necessary code. Bosch was apparently concerned about the legality of the software and asked Volkswagen to assume responsibility if the fraud was discovered, but Volkswagen refused. Starting in 2008, Bosch supplied approximately 17 million motor control and mixture control devices containing illegal software to various manufacturers both domestically and globally. With such software, the automobiles fitted with Bosch's devices emitted more nitrogen oxides than allowed under regulations. On 1 February 2017, Bosch agreed to pay consumers in
6716-411: The next four years. They will be opening two new facilities for manufacturing a computer chip development in the cities of Dresden and Reutlingen. Chairman Stefan Hartung said the company is not interested in building cutting-edge semiconductor facilities but focuses on 40 and 200-nanometer chips used in the automotive industry . In September 2023, it was announced Bosch had completed the acquisition of
6808-433: The original 20XE/C20XE these were intended more for mainstream application (as opposed to racing and high-performance applications) in response to tightening emissions standards, and to reflect the overall family car market moving towards multivalve technology as was being increasingly found in competing vehicles. Again, these engines have no commonality with the later GM Ecotec engine introduced in 1999 , and first used in
6900-543: The original design include under-piston oil cooling, a revised turbocharger unit and the deletion of the contra-rotating balancer shafts in the 240 hp (179 kW) Z20LEH engine (as used in the Astra VXR), to reduce mechanical losses. The Z20LEH also features high quality Mahle forged pistons, which are much stronger than the cast pistons fitted to the Z20LET, Z20LEL and Z20LER. The 2.0-litre X20SED D-TEC 16 Valve DOHC MPFi
6992-422: The other two. Since an engine's oil circulates at much higher pressures than its coolant, oil in a porous head has a tendency to gradually seep into the coolant galleries. A typical symptom of a porous head is usually a ' mayonnaise '-like substance forming somewhere inside the cooling system (usually, this can be found residing on the coolant reservoir cap). However, depending on the degree of porosity, symptoms of
7084-408: The primary throttle body. This is closed by a motor/arm assembly when the traction control ECU senses loss of grip/spin at the wheels. The engine was also equipped with a different throttle position sensor (six pin, as opposed to three), and a different coolant temperature sensor (which was black, as opposed to the normal light blue colour). The engines that appeared in the early 1990s also swapped
7176-519: The same year, the company opened a new testing center in Vaitoudden, close to Arjeplog in north Sweden. A new developing center in Abstatt , Germany followed in 2004. In 2002, Bosch acquired Philips CSI, which at the time was manufacturing a broad range of professional communication and security products and systems including CCTV , congress, and public address systems. In the 2000s the company developed
7268-557: The servicing requirements of the older overhead valve units that the Family I/II replaced) would often exacerbate the problem by changing the oil themselves within the running in period. Opel solved the problem by improving the metallurgy of the camshaft and followers, and changing the lubrication specification. Another issue (also common to the Family II), revolved around the water pump, which sits in an eccentric shaped housing and doubles as
7360-416: The smallest capacities of the Family II have also been manufactured with larger capacity versions of the Family I block. Early build versions of the engine gained a notorious reputation for camshaft and follower failure – this was largely due to a special lubricant being used in the engine during the running in period, which would be changed for conventional oil at the first service. Many owners (familiar with
7452-466: The timing belt tensioner. If poor quality antifreeze (or if no antifreeze was used), corrosion would jam the water pump in its housing making it impossible to tension the belt. Later versions of the engine incorporate a separate tensioning/jockey pulley for tensioning the belt. GM do Brasil specializes in SOHC , petrol-powered and FlexPower (powered with ethanol and/or petrol, mixed in any percentage) engines. GM Brasil also made 16-valve versions of
7544-560: The vehicle will still comply with MOT regulations. The C20LET engine was introduced in 1992, and was fitted to the Opel / Vauxhall Vectra Turbo / Cavalier Turbo , Calibra Turbo , and the South African made Opel Astra 200t S . It is similar to the C20XE, apart from the primary addition of a KKK -16 turbocharger , forged Mahle pistons , Bosch Motronic M2.7 electronic engine control unit , and black plastic plenum/'top hat' shroud with
7636-627: Was also exported for use in the Brazilian Corsa GSi. Applications: Updated version introduced from 2000, with lighter cast-iron cylinder block and camshaft driven by toothed belt . Features EGR valve and electronic throttle for reduced emissions. Ecotec TwinPort Family 1 engine (Z16XEP) is used in: Daewoo Motors licensed and produced a variant of the Family 1 engine. These engines were built exclusively at Bupyeong engine plant and marketed as E-TEC . Like all Family 1 engines they feature
7728-565: Was available in silver only). 1994 saw the introduction of the Ecotec series - which again consisted of a DOHC 16-valve cylinder head (this time co-developed with Lotus) mounted atop a development of the Family II block. The 2-liter versions therefore became the X20XEV , now producing 136 hp (101 kW) and taking on the GM Ecotec name. In its final, 1999 iteration, it became the X20XER . unlike
7820-531: Was built by Holden and used in the Daewoo Nubira . GM Family 1 engine The GM Family I is a straight-four piston engine that was developed by Opel , a former subsidiary of General Motors and now a subsidiary of PSA Group , to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel / Vauxhall . The engine first appeared in
7912-539: Was called the 12ST (also A12ST and S12ST in versions for the Austrian, Swiss, and Swedish markets), it used a 77.8 mm (3.06 in) bore and a 62.9 mm (2.48 in) stroke to produce a displacement of 1,196 cc (73.0 cu in). This version, only carburetted, was used in the Opel Corsa . In around 1990 a new, version with 72.0 mm × 73.4 mm (2.83 in × 2.89 in) bore and stroke,
8004-480: Was equipped with exhaust gas recirculation ( EGR ) to reduce nitrogen dioxide emissions and air injection reactor (AIR) to speed up the warming up of the catalytic converter and to reduce unburnt hydrocarbons and carbon monoxide . The engine is capable of producing 100 kW (136 PS ; 134 bhp ). A higher output version called the X20XER produced 118 kW (158 hp) at 6500 rpm and 188 N⋅m (139 lb⋅ft) at 4300 rpm. The Z20LET
8096-498: Was made available for the taxi market which could use gasoline, alcohol, and natural gas . These engines formed the basis of the modern Family II lineup, starting with the 16SH (1600S) version in the Opel Kadett D/Ascona C (Vauxhall Astra Mk1/Cavalier Mk2) in 1981. Configuration was limited to a single over head cam, and two valves per cylinder in a cross flow layout (8 valves total). Superficially these engines look similar to
8188-696: Was portrayed as the world’s No. 1 company for packaging technology . In 2018, Bosch decided to look for a new owner for this business. Bosch's in-house provider of assembly systems, Robert Bosch Manufacturing Solutions GmbH, Stuttgart, remains part of the Bosch Group; up to now, it has been part of the Packaging Technology division. In addition, the Bosch Connected Industry business unit, which develops software and carries out Industry 4.0 projects for internal and external customers, has been part of
8280-555: Was replaced with a front section used also in Opel Astra, probably as a cost-saving measure. Applications: The first generation Ecotec engines are belt-driven 16-valve DOHC engines, with cast-iron cylinder blocks and aluminum cross-flow cylinder heads . They feature sodium-filled exhaust valves , a cast steel crankshaft , and a spheroidal graphite flywheel . They also feature exhaust gas recirculation (EGR), secondary air injection , and Multec M engine control with sequential multiport fuel injection . The 1.6 L version
8372-844: Was represented by trading partners on every continent: in 1906 in New York (U.S.) and Johannesburg (South Africa), in 1907 in Sydney (Australia), in 1908 in Buenos Aires (Argentina), in 1909 in Shanghai (China), in 1910 in Rio de Janeiro (Brazil), and in 1911 in Tokyo (Japan). Bosch opened the first factory outside Germany in Paris, in 1905, and the first on another continent in 1912 in Springfield, Massachusetts (USA). In 1917, Bosch
8464-561: Was transformed into a corporation and remained so until 1937, when Robert Bosch became the sole owner again after buying back his shares. In the process, the company became a limited liability company (GmbH). After the First World War, Bosch lost most of its international holdings, including its U.S. factories. The company had to largely rebuild its international activities. This included opening up further South American and Asian regions. In 1922, for example, Illies & Company established
