The VG30S is a 2,960 cc (3.0 L) SOHC twelve-valve engine with an electronic carburettor which produces 148 PS (109 kW; 146 hp) at 4,800 rpm and 234 N⋅m (173 lb⋅ft) at 3,600 rpm. This engine was mainly offered in export markets with more lenient environmental regulations, such as the Middle East and Africa.
VCT is used in Ford's Triton 5.4L 3-valve V8 engine, the Australian Barra 182 and 240 Inline-6s, and Ford's 4.6L 3-valve V8 engine used in the 2006-2010 Ford Explorer and 2005-2010 Ford Mustang GT. The 2.0L Zetec inline-4 used in the 1998–2003 Ford Escort ZX2 , Ford Contour, and 1999–2002 Mercury Cougar used VCT on the exhaust camshaft.
The US-market engine was the same 3.3-liter V6 unit as used in the Pathfinder, producing 168 hp (125 kW) at 4,800 rpm and 196 lb⋅ft (266 N⋅m) at 4,800 rpm. This was generally considered underpowered for the segment, with a 0–60 mph (97 km/h) time of 12.4 seconds in period testing. [ 6 ]
SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
The VE engine is a 3.0 L (2,960 cc) piston V6 engine from Nissan.It is based on the Nissan VG engine and was only used for the 1992, 1993, and 1994 model years. This engine has an iron block, aluminum cylinder heads with 4 valves per cylinder and dual overhead camshafts, variable valve timing on the intake camshafts, coil-on-plug ignition, and an available variable intake manifold (5-speed only).
The six-cylinder 3.0-litre VG30i (early years) or VG30E (later years) engine increased power and torque only modestly. This was the only engine option for the one-tonne longbed truck. [ 40 ] The V6 was no longer available in the US starting with the 1996 model year because Nissan was unable to meet the requirements of the new OBD-II emissions ...
The RB engine is an oversquare 2.0–3.0 L straight-6 four-stroke gasoline engine from Nissan, originally produced from 1985 to 2004.The RB followed the 1983 VG-series V6 engines to offer a full, modern range in both straight or V layouts. [3]
In four-stroke cycle engines and some two-stroke cycle engines, the valve timing is controlled by the camshaft. It can be varied by modifying the camshaft, or it can be varied during engine operation by variable valve timing. It is also affected by the adjustment of the valve mechanism, and particularly by the tappet clearance.
