In 2010, an extended rear body variant for the FB variant called the Exceed was added. In 2014, local truck body manufacturer Centro Manufacturing launched a minibus version of the L300 called the XV Mikrobus. It is built on the FB Exceed platform and is meant to be used as a public utility vehicle, a school bus, or an ambulance.
The 4N1 engine family is the world's first to feature a variable valve timing (intake side) system applied to passenger car diesel engines. [10] All engines developed within this family have aluminium cylinder block, double overhead camshaft layouts, 4 valves per cylinder, a common rail injection system with a variable-geometry turbocharger.
The SOHC eight-valve 4G54 (also known as the G54B) displaces 2.6 L (2,555 cc), with bore & stroke at 91.1 mm × 98 mm (3.59 in × 3.86 in). The G54B for the US market had a cylinder head with additional jet valves to improve emissions (MCA-Jet system).

A cylinder head of a four valve Nissan VQ engine engine. A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust).A multi-valve engine has better breathing, and with more smaller valves (having less mass in motion) may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.
The most common final control element in the process control industries is the control valve. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point. [1]
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.
