2.0 TFSI EA113 HPFP-rollerkit zonder nokkenasnok

Deze kit bevat alle onderdelen die nodig zijn om de nokvolger-type hogedrukbrandstofpomp om te bouwen naar een rolvolger-kit, net als bij de nieuwere EA888 TSI-motoren. Bij de 2.0 TFSI EA113-motor komt overmatige slijtage van de nokvolger die de nokkenaslob raakt vaak voor. 

If the cam follower wears all the way through, excessive damage can be caused to the engine and intake camshaft. This conversion protects against this problem, and ensures the reliability and smooth operation of your high-pressure fuel pump, without the need of replacing the cam follower again.

• Dit product is uitsluitend ontworpen voor standaard nokkenassen en standaard nokprofiel. 

TECHNICAL INFORMATION
The first VW engine with direct injection was designed for low power usage; however, its development was not improved. At higher power levels, increasing fuel pressure is necessary to overcome the pressure inside the combustion chamber for a homogeneous fuel dispersion.

A major drawback of the EA113 2.0L TFSI engine's fuel system is that as fuel pressure increases through ECU tuning (remapping), the high-pressure mechanical pump, which operates with the camshaft, relies on sliding friction. This means the tappet rubs against the cam lobe, and with the increase in fuel pressure, this surface endures additional load. Consequently, the oil film breaks down, causing direct contact between the factory tappet and the cam lobe, which leads to excessive wear due to increased friction and heat. This results in metal debris filling the engine, often damaging the oil pump and causing complete engine failure.

The key to our improved kit lies in rolling friction. The piston that reciprocates on the cam lobe, with the installation of a cylindrical bearing, rolls smoothly, significantly reducing friction and heat. This also provides a slight increase in power due to reduced friction, but more importantly, it ensures long-term durability of the assembly.

TECHNICAL SPECIFICATIONS
The body is made from forged aluminum 6026 T-6 EUROPAL in a single machining phase on our 5-axis CNC lathe, ensuring perpendicularity and optimal fit between the cylinder and piston, while also reducing surface roughness.

Een belangrijk voordeel van ons product is de geanodiseerde coating, die het aluminium oppervlak verhardt en tegelijkertijd de wrijvingscoëfficiënt tussen de zuiger en het huis bij hoge motortoerentallen aanzienlijk verlaagt, waardoor zuigerstuiteren tot een minimum wordt beperkt. Daarnaast beschermt de geanodiseerde coating het huis op lange termijn tegen oxidatie en zorgt deze voor glans, esthetiek en kleur in het motorruim.
