Big m8 was spawned by the minor contact of one of the chip ganassi ford gt racers and the 81 m8 gte seen in the lead photo. Eagle eyed fans immediately noticed how bizarrely oversized the grand tourer m8 looked next to the slim supercar bodied ford. It was developed in late 2016 and made its competitive début in imsa weathertech sportscar championship and fia wec for the 2018 season and thus marking bmw motorsport s return to 24 hours of le mans after a six year hiatus. Pin tweet shop the meme. Naturally this car raced in the same class as the ford gt despite being entirely different in every way. In january 2018 the gt sports car contested its first race at the 24 hours of daytona. The m8 gte is powered by a motorsport...
Why is vanos needed in an engine. Since 2001 vanos is often used in conjunction with the valvetronic variable valve lift system.

How bmw vanos system works. The name is an abbreviation of the german words for variable camshaft timing. This is a bit hard to explain using only text so here goes nothing. The system uses a gear on the vanos actuator and a gear on the camshaft.
The vanos system uses oil pressure to control the position of the intake and exhaust camshafts. The initial version was solely used on the intake camshaft while the later double vanos systems are used on intake and exhaust camshafts. The system variably adjusts the timing of the valves by changing the position of the camshaft relative to the drive gear.
Bmw vanos oil solenoids helical gears and german space magic. Later dual vanos systems operate at all engine speeds. The s62 vanos differs in some details from what is described in the linked text but the principle is more or less the same.
Early models only varied the intake camshaft where later models vary both the intake and exhaust cam shafts. If you ve ever wondered what vanos stands for it s variable nockenwellen steuerung which literally means variable camshaft timing. The bmw vanos system allows variable camshaft timing of the engine.
The early vanos systems are very basic and work to make more power. The intake and or exhaust cams vary in relation to the crank shaft to optimize engine performance at different engine speeds. A vanos solenoid operated by engine oil pressure and controlled by the engine control module ecm advances and retards intake valve timing by rotating the modified camshaft sprocket assembly.

A solenoid then controls the amount of oil pressure being applied which controls the movement of the cam gear outward or inward effectively controlling the timing of the valves.
The way bmw went about solving the variable valve timing puzzle is simple yet ingenious. Vanos is a variable valve timing system used by bmw on various automotive petrol engines since 1992. At low engine speeds intake valves open late ensuring smooth engine operation.
At lower engine speeds the vanos system opens the valves later during the intake stroke. The bmw vanos variable nockenwellen steuerung in german is a variable valve timing technology developed by bmw. For the s62 for each cam the chain drives the vanos gearbox the gearbox drives the splined shaft using helical gears on the inside of the gearbox outside of the splined shaft and the splined shaft drives the camshaft using straight gears on the outside of.
This increases the vacuum and scavenging effect generated by the piston traveling downward. How does the bmw vanos system work.
