bmw m88 turbo

In contrast to the M88, the M88 / 3 in the BMW M635 CSi and BMW M5 and in the BMW M745i (South Africa variant) is built in the traditional way , namely in the front - which of course is mainly because they were already in production as front-engine vehicles with rear-wheel drive . For the detection of the load condition , a damper air flow meter is used; the puffer fish injection took its information on the load condition from the throttle position, but since there was no information about the actually sucked air flow, this is in practice rather as a targetLoad state (possible deviations of the intake air mass, eg due to clogged air filter, can not be detected in this way). [10] The Kugelfischer fuel injection was replaced with Bosch Motronic producing 210 kW (286 PS; 282 hp) at 6,500 rpm and 340 N⋅m (251 lbf⋅ft) at 4,500 rpm. For Group 5 racing, the M88 engine was turbocharged and became known as the M88/2. The BMW E23 is the first generation of the BMW 7 Series luxury cars and was produced from 1977 to 1986. The M88/3 was also fitted to the South African BMW 745i, due to packaging problems with the turbocharged M102 engine which was used in other markets.[12]. In addition, shortening the camshaft opening times increased the internal exhaust gas recirculation , which reduces the raw HC emissions (emissions before catalytic converter).

The M90 sold in Europe and most other markets (except North America) used a compression ratio of 9.3:1, did not have a catalytic converter and produced 160 kW (215 hp).
The M88 was produced alongside the BMW M30 engine, as the higher performance engine.

Different years of M90 engines used both Bosch Motronic and Bosch L-Jetronic engine management systems. S38 has less common with M30B35. This means not only considerable cost savings due to the elimination of the equally expensive and highly precise precision mechanics of the blower injection, but also further possibilities for the efficient coordination of ignition timing and injection quantity to the respective operating state of the engine. m) @ 5500rpm. The M88 was the original iteration of the engine and was fitted to the BMW M1. Origines et évolution La famille de moteurs M88 Il est né dans le milieu ' soixante-dix BMW quand il a été décidé de créer une voiture de sport à utiliser en compétition et en mesure de contrer la domination Porsche dans le champ GT.

Deviations from the M88: Displacement increased to the limit of 3.5 liters, butterfly valves replaced by flat valves, valves and channel cross-sections enlarged, Performance: depending on the charge pressure of up to 625 kW (850 hp) at 9000 min, Deviations from the M88 / 1: reduced capacity, exhaust gas turbocharging, charge pressure 1.2 to 1.4 bar.

The torsional vibration damper on the front crankshaft stump, however, had to be retuned for the higher revs of the M88 / 3. It is based on the DOHC version of the BMW M49 engine, which was used in the BMW 3.0CSi racing cars. In 1986, the E23 was replaced by the E32 7 Series, however, the E23 models (called L7) remained on sale in the United … The S38B36 engine designed especially for BMW E34 M5 which released in 1988.

Thus, the crankshaft with a long stroke corresponds to the 1982 built 3.5 l- M 30 , the engine block with oil supply and water pump and the crankshaft , the flywheel and the belt drive together with the ancillaries were taken from built after 1982 3.4-liter six-cylinder engine.

The BMW M88 is a straight-6 DOHC petrol engine which was produced from 1978-1989. Terrain, Production, Distribution, Dates de sortie, Les Clayes-sous-Bois. [11] It has a compression ratio of 10.5:1. The control of injection and ignition are taken over together by a Bosch Motronic. The M88/3 was also fitted to the South African 745i, due to packaging problems with the turbocharged M102 engine which was used in other markets. In North America up until 1989, the BMW S38 engine was used instead of the M88. The fuel pressure in front of the injection valves is 3 bar; actually, the pressure difference to the intake manifold vacuum for all engine operating conditions is 3 bar, thus the injected fuel quantity is directly proportional to the driving time of the injectors. The M90 engine is a lower performance SOHC engine that was based on the M88/1. In North America up until 1989, the BMW S38 engine was used instead of the M88. It is based on the DOHC version of the BMW M49 engine, which was used in the BMW 3.0CSi racing cars.[1][2]. It utilizes the same block from the M88 and maintains the same bore and stroke, but borrows its head from the BMW M30 engine family.
The M88/1 engine was modified for use in the E24 M635CSi and E28 M5 and was known as the M88/3. riders on the storm. Typically identified by a white L painted on the block behind the oil filter housing and coolant water passages on the side of the block.

[6][7] The bore is 93.4 mm (3.68 in) and the stroke is 84.0 mm (3.31 in), resulting in a displacement of 3,453 cc (210.7 cu in). [8] A dry sump is used.[9].

The M90 sold in Europe and most other markets (except North America) used a compression ratio of 9.3:1, did not have a catalytic converter and produced 160 kilowatts (210 hp). This race engine produced up to 900 hp (670 kW).

In 1989, an updated version of the S38 became the worldwide replacement for the M88. [4] The engine and especially the supercharging largely correspond to Schnitzer developed M49 / 4 engine, which was already driven in 1976 in the 3.0 CSL race touring car of Ronnie Peterson in Group, from 4/84 in the model BMW M635 CSi (E24) , from 1985 in the BMW M5 (E28), Camshaft opening time 264 degrees crank angle (both camshafts are identical), camshafts driven by single row roller chain, Others: electronic intake manifold injection and ignition ( Bosch Motronic M1.1) with air damper, wet sump lubrication, exhaust manifold, single-disc dry clutch , engine installed inclined by 30 ° to the right. The M88/1 engine was modified for use in the M635CSi and E28 M5, this engine was known as the M88/3.
