Blue Whale Blue Whale 250 Blue Whale Blue Whale 250 250 250 Technical Tips Layout Sensor number= 7 pcs SW number= 2 pcs @ EX cam position sensor use to check the piston position of TDC (compression or exhaust) because the injection control is sequential. On starting group injection is used for quick starting. If you don’t use group injection you have to crank 3 rotations (only one EX cam position sensor) in order to determine which cylinder to inject have to crank 3 rotations (only one EX cam position sensor) in order to determine which cylinder to inject. @ IN cam position sensor is used to check and feed back the V .C.T. action to the ECU. 16

Blue Whale Blue Whale 250 Blue Whale Blue Whale 250 250 250 Technical Tips Oil Control Valve Movement by solenoid OCV is constantly regulating y g g the oil pressure in the actuator so that it retards or advances until required camshaft angle is met. 0.2mm mesh Movement by spring T t d f Tested for 400h without 400h ith t changing oil > no problems. Oil change > every 100h Over 2000 RPM every 0,2s a measurement takes place, recalculating the timing 26

( The throttle valve will move to a closing position.) @During operation:The E.T.V . receives an order from the A.P .S., then the throttle valve moves to open/close. @Key SW OFF:The throttle valve will move to a fully open position first and then fully closed. By doing this the engine learns the fully open and closed positions. If during this SW OFF procedure the engine is SW ON again, this learning action is stopped stopped. 28

Blue Whale Blue Whale 250 Blue Whale Blue Whale 250 250 250 Technical Tips Throttle cable Installation Fully closed position Fully open position Pull the throttle cable towards the engine to remove any free play in the cable before adjusting the position of the throttle cable joint. Check the mark “b” on the lever “4” has passed the mark “c” on the stopper “5” when the remote control lever is in the fully open position. If the pp y p p adjustment procedure is out of specification the throttle valve may not fully close when throttle lever is fully reduced. 31
