TVR RG 121
Crankshaft scraper plate
Crankshaft scraper plate for billet crankshaft. As part of the continued development of the TVR Speed 6 engine we have complemented the billet crankshaft with a dedicated scraper plate. Some of the internal losses of the internal combustion engine are related to oil control issues arrising when the crankshaft is revolving at high speed and sweeping around with it a "cloud" of oil mist. This creates a noticeable parasitic drag on the crankshaft. To combat this situation scraper plates are very accurately designed to "cut" this oil mist away from the rotating cranshaft and allow it to be removed from the engine by the scavenge pumps. Because of the clearances required to make this work this scraper plate can only work with our fully machined billet crankshaft with 92mm stroke and our forged connecting rods.
