The variable valve timing (VANOS) is a continuously variable design and is present on both the intake and exhaust camshafts. The VANOS units were designed as integral components of the chain drive, and the adjustment ranges are 63 degrees for the intake camshaft and 60 degrees for the exhaust camshaft. [4]
The only problem experienced with this M111 excellent reliability motor is the originally installed Victor Reinz headgasket, which eventually tore apart by age, and made the top lose coolant on the side. Other than that, only some year models, had bad insulation on the engine wiring, that needed all the wiring to be replaced.
VCT on the intake camshaft is used primarily for increasing engine power and torque as the PCM is able to optimize the opening of the intake valves to match the engine conditions. [ 2 ] 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 ...
The first CamPro engine used in older Gen-2 models.. The first CamPro engine made its debut in 2004 fitted to the newly released Gen•2 models. It was codenamed S4PH and was a DOHC 16-valve 1.6-litre engine that produced 110 bhp (82 kW) of power at 6,000 rpm and 148 N⋅m (109 ft⋅lbf) of torque at 4,000 rpm.
The active valve control system (AVCS) is an automobile variable valve timing technology used by Subaru. It varies the timing of the valves by using hydraulic oil pressure to rotate the camshaft, known as "phasing", [1] in order to provide optimal valve timing for engine load conditions. The system is closed loop using the camshaft sensors ...
The crankshaft has a shorter stroke, which lowers the displacement, but allows the engine to safely rev to higher RPM. Although this engine has 1.6 L of displacement, it has more aggressive camshaft specifications. It manages to make 173 hp (129 kW). The camshafts from this engine are considered to be an upgrade for SR20VE owners.
N-VTC varies valve timing by rotating the affected camshaft relative to the sprocket; valve lift and duration are not altered. This rotation is achieved when an electric solenoid, controlled by the car's ECU, allows pressurized engine oil to flow into and through the cam and into a slave mechanism, axially advancing camshaft timing relative to ...
Three-way catalytic converter, wide-band heated oxygen sensor The GM L3B engine is a turbocharged four-cylinder gasoline engine designed by General Motors. It is an undersquare aluminum DOHC inline-four displacing 2.7 liters (165 cid) and tuned for strong low-end torque.
