Terminologie NISSAN

ONEVIA = S13 Silvia avec un devant de 180sx
SILEIGHTY = 180sx avec un devant S13 Silvia
ZENKI = Premiere génération de S13 (US 240sx 89-90)
CHUKI = Deuxième génération de S13 (US 240sx 91 @ 93)
KOUKI = Troisième génération S13 (N'a jamais vu le jour aux US, mais au Japon c'est S13 1994-1998, c'est les 180sx avec le SR20DET black top)
KOUKI tailights = Troisième génération de tailights 180sx (Celles formées de deux ronds)
180SX taillights = celles qu'on a ici

La définition que j'ai trouvé de TOUGE = "A cute, winding mountain road"

Vtc Vve Vvl Ve,k

Hitachi Unisia Automotive has a variety of variable valve systems to offer. These have been developed with priorities ranging from performance to application, so that they can also be offered as sub-systems.
The three systems introduced here all improve fuel consumption and emissions while maintaining engine torque output in any driving situation.
Such systems are indispensable not only for vehicle to be produced in the future but also for current models.

05_01-2.jpg





VTC : Valve Timing Control System

VVL : Variable Valve Lift System and Timing

VVE : Variable Valve Event and Timing System

VE‚k : Continuous Variable Valve Event and Lift Control System

EVA : Electromagnetic Valve Actuator





VTC : Valve Timing Control System
05_01-6.jpg




Features

Hitachi Unisia Automotive's unique compact design.
Low friction characteristics make use at low engine RPM possible.


Applications

Cam be installed without valve train modification.
Cam be installed both intake and exhaust camshaft.
Cam be combined with VVL or VEL.



VVL : Variable Valve Lift System and Timing

05_01-3.jpg


Features

Lightweight construction.
Compact design
Easy engine installation
Low friction
Applications

For swing-arm valve train.
Cam be installed both intake and exhaust camshaft.
Cam be combined with VTC or VEL.


VVE : Variable Valve Event and Timing System
05_01-4.jpg



Features

Cam be installed on any engine with direct acting valve train.
Cam be installed on any engine.
Applications

Cam be installed on any engine.
Cam be installed both intake and exhaust camshaft.
Cam be combined with VTC.

VE‚k : Continuous Variable Valve Event and Lift Control System

05_01-5.jpg

Features

Continuous change mechanism for both valve lift and event from lowest lift (or 0 lift) state to a long event and high lift state.
Low driving friction owing to desmodromic princple.
Quick changing response by electric powered actuator, enabling non-throttling load control.


Applications

For direct-acting and swing-arm valve train.
Cam be installed both intake and exhaust camshaft.
Can be installed in conventional cylinder-head without need of cam-shaft axis position change from conventional position.
Freely adjustable valve characteristics combined with VTC (Ultimate System).
