Since its launch in 1985, the LuK Dual Mass Flywheel (DMF) has been fitted as original equipment in ever-increasing numbers of vehicles. When a conventional single-mass flywheel  and conventional clutch reach their torsion angle limits at around 18°, the DMF, with its decoupled dual masses and a torsion angle of up to 100°, can absorb …

Transmission sensors record the transmission speed. This information is needed by the ECU to adjust the shifting pressure and for the decision which gear must be chosen. Function There are two different types of transmission sensors, a hall sensor and an inductive pickup. Their function is send voltage signals produced by changing magnetic fields developed …

Dual Mass Flywheels (DMFs) set a new standard for drivetrain noise insulation and vibration damping when launched by LuK in 1985. A total of 63 million DMFs have since been manufactured, and one in three cars on European roads currently use DMF technology to aid comfort and reduce fuel consumption and CO2 emissions. Now pendulum-type …

GLYCO explains the vital role of bearing clearances in modern engines. As engine builders continue to extract more power from less fuel, modern engines are subjected to greater temperatures and loads. With bearings taking the strain, bearing clearances are microscopic spaces with huge impact. BEING CLEAR ABOUT CLEARANCESA bearing clearance is the difference between the …

febi explains the importance of regularly inspecting high-pressure fuel pump cam followers to protect against consequential damage. VAG has been using fuel-stratified injection (FSi) to power their petrol engines since 2000. This system was designed with the aim to improve fuel consumption and engine efficiency. By running the engine with leaner fuel mixtures, emissions are …

TRW was recently asked if a vehicle with a leaking wheel cylinder on the offside should have the nearside cylinder replaced as well. The answer is ‘yes’ and it is recommended that parts such as wheel cylinders should always be changed in axle sets. However, the age of the vehicle should also be taken into account. …

INA, inventor of the overrunning alternator pulley (OAP) warns factors and garages to beware of cheap imports and explains why it is worth investing in OE. The power and compression strokes of the internal combustion engine involve the acceleration and deceleration of the crankshaft whose rotational irregularities are transferred to the engine accessories through the …

With Valeo, make it simple to detect wiper defects … make it easy to sell! Wiper blades are a key visibility tool for drivers. While checking a car, it’s important and compulsory to have a look at them.

BOSCH speaks about diesel pressure sensors and pressure control valves. Fitted into a diesel engine, a diesel pressure sensor functions to relay a pressure drop in the common rail system to the ECU. The ECU uses this information to restore the pressure via a high-pressure pump. When modern vehicles experience common rail system problems, faulty …
