The glowplug of engine is a Turbo type glowplug. Turbo glowplugs have a different shape than Standard glowplugs and therefor are not interchange able with engines that are using Standard glowplugs.
The sleeve is manufactured with 5 transfer ports designed after fluid-dynamics studies, so we increased the maximum power, and taking care of the fuel consumption.
The crankshaft is manufactured with a larger bore intake to increase the mixture flow;and has a special shape to optimise gas-flows in the engine.
The R7 conrod is made from a superlight alluminium which has been checked ultrasonic. The specific form of the R7 creates little turbulence inside the engine while running.
