Fuel Evaporation Control System

Fuel Line Vent Valve

The control valve is closed when the engine is stopped, idling, or at full throttle. Fumes containing evaporated fuel from the tank flow to the charcoal filter where the vaporated fuel is trapped by the activated charcoal. With the engine running at part throttle, the control valve is open. Fresh air is drawn from the air cleaner through the charcoal filter and into the intake duct at the air-sensor housing. The evaporated fuel is drawn out of the activated charcoal and burnt up in the engine...

Drive Train

The front-mounted engine and rear-mounted transmission are bolted on a connecting tube to become one solid drive unit. Power flows from the engine's crankshaft 1 via the flywheel 2 to the single dry plate, clutch 3 . A connecting sleeve 14 joins the drive shaft 13 with the input shaft of transmission 15 . The single-piece drive shaft 13 runs on four guide bearings 11 in central tube 12 . Between the 2nd and 3rd guide bearing there is a vibration damper 9 , which is mounted with soft rubber...

Adjusting Ignition Timing For 1980 Models Note

Gozanti Cruiser

The 924 is equipped with a breakerless transistor ignition system. The ignition must be turned off when connecting a tester to the ignition coil. Measurement of the dwell angle is not required 1. Run engine to operating temperature oil temperature about 80 to 90 C . 0 TDC at 950 50 rpm with vacuum hoses connected 3. Vacuum hoses of USA version remain connected. At idle speed the pertinent mark on flywheel must align with reference edge.

Transmission Shift Pattern

The shift pattern of the 924 Turbo differs from that of the 924. The 924 Turbo has the first gear and reverse gear on one shift gate so that the shift pattern is the same as the 928. TRANSMISSION - Arrangement of Gears, Power Flow Spring 9 continuously holds the selector shaft 13 in the center shift gate 3rd and 4th gear . For example, to engage 1st gear, spring 9 will have to be compressed in order to get into 1st 2nd gear gate. This spring force is also important when shifting from 1st to 2nd...

Reverse Gear Lock Out

Since 5th gear and reverse gear are in the same shift gate, there must be a lock-out to prevent unintentional engagement of reverse gear when downshifting from 5th gear to 4th gear while moving forward. Washer 3 performs this function. The torque is transmitted from the drive pinion to the ring gear 2 . Since the ring gear is bolted to the differential carrier 4 , the differential will turn at ring gear speed. Two different size taper roller bearings are used for the differential. The large...
