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 the sprocket. Valve to crank angle timing varies depending on whether engine speed is high or low and changes at fixed intervals.
The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
Continuous Variable Valve Timing Control System (CVVTCS) is an automobile variable valve timing technology developed by Nissan. It is also used in a twin CVTC configuration on engines like the Nissan Juke's MR16DDT engine. CVVTCS is the successor to Nissan's earlier valve timing implementation NVCS. [1] [2]
The twin-turbo VQ30DETT is an engine used only in Nissan's race cars, primarily in the Super GT (formerly the JGTC). First used on the Skyline GT-R race cars during the 2002 season, this engine subsequently powered the Fairlady Z race cars. Homologation rules allow them to use the VQ30DETT in lieu of the stock VQ35DE. Race output of this engine ...
Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
Like with the outgoing CA18DET, the SR20DET was a turbocharged intercooled engine in top form. It was Nissan's popular four-cylinder turbocharged engine fitted into a wide variety of cars, most notably the S13-chassis Nissan Silvia and 180SX. It also came in the Pulsar GTI-R and the Nissan Bluebird.

The MR20DD is a 2.0 L (1997 cc) engine developed by Nissan with direct injection and twin variable valve timing control. The MR20DD engine is "SU-LEV" certified in Japan, and produces 108 kW (145 hp; 147 PS) at 5600 rpm and 155 lb⋅ft (210 N⋅m) of torque at 4400 rpm in its first permutation, with a 11.2:1 compression ratio.
