Witam wszystkich,

Zastanawiam się czy silnik w Sportage II 2.0 16v z 2008r o oznaczeniu G4GC ma zmienne fazy rozrządu. Szukałem w internecie i nie udało mi się znaleźć takiej informacji. Bardzo bym prosił o odpowiedź kogoś, kto lepiej zna temat :)

Nie ustałem w poszukiwaniach i znalazłem w końcu informację którą chciałem, jednak dopiero na storach angielskiej Wikipedii: https://en.wikipedia.org/wiki/Hyundai_Beta_engine

During 2001-2002, the new Beta II (G4GC) engine made its debut in models such as the XD Elantra and GK Tiburon. Output is 138 hp (102 kW) at 6000 rpm with 136 pound force-feet (184 N⋅m) of torque (184 N·m) at 4500 rpm[citation needed]. It has a cast iron engine block and aluminum DOHC cylinder heads. The latest version of the 2.0L Beta engine (G4GC) features CVVT, which exists only on the intake side, a first for Hyundai/Kia. The following changes were noted.

Redesigned block with external contouring of cylinder bores (instead of flat sides), extra ribbing and one extra transaxle fixing point (now 5)(less NVH)
Crankshaft now has 8 counterweights instead of 4.(NVH)
Cast & ribbed aluminium sump pan (instead of pressed steel sheet) with stronger joint to transaxle (NVH)
Reshaped combustion chambers, ports & pistons (performance, [fuel] economy, emissions)
20 mm (0.8 in) longer intake rams, 8% smaller surge tank, resonator added, spark timing and valve lift optimized, lighter valve springs, denser conrod bearings, returnless fuel system (instead of return type) with higher fuel pressure and smaller injectors (torque spread and economy)
Cylinder head machined to more precise tolerances
Head gasket now 2-layer (instead of 3)
Idle speed reduced to 700 rpm from 800 rpm (NVH)
Hydraulic engine mounts (4) instead of rubber (NVH)
Heat shield installed between engine and air filter, reducing heating of induction air.
New camcover with I-piece high-specific gravity polypropylene baffle (ilo 2-piece pp)
Oil flow reduced (economy)
Mechanical valve lash adjusters (solid lifters) replace hydraulic, improving valve clearance precision (durability).
Lower valve spring load reduces valve train friction (performance).
Engine cover installed (NVH and dress up engine bay)
Catalytic converter now upstream adjoining exhaust manifold (ilo under car) (emissions)
Other detail changes to: alternator, intake manifold brace, power steering & a/c pulleys, idle speed actuator, oil filler cap & drive plate between engine & torque converter [1]
In 2008 the Beta II was modified to produce 142 horsepower (106 kW) and 137 lb⋅ft (186 N⋅m) of torque.
