What does an intake valve actuator do?
The Intake Manifold Actuator is mounted on an Intake Manifold that acts as a passage of air that is sucked into the cylinder of the engine.
What does IVA pressure sensor do?
The sensor converts the rail pressure into an electrical signal. The ECM monitors the signal in order to determine the pressure of the oil in the rail.
What is an intake valve actuator c15?
The intake valve actuators are used to control the closing of the rocker arms for the intake valves. This allows the Engine Control Module (ECM) to precisely control the intake valves during closing. The intake valve actuator is a hydraulic system that uses the engine oil to operate.
How is a variable intake valve actuator actuated?
Electrohydraulic VVL systems commonly use a lost motion hydraulic linkage controlled by electrically actuated valves to vary the valve lift and/or to control secondary valve events. They have been used in both diesel and gasoline engine applications.
What does C15 Acert mean?
Advanced Combustion Emissions Reduction Technology
So how does the new C15 with ACERT (Advanced Combustion Emissions Reduction Technology) manage to be clean and powerful? The idea is to run the engine lean and mean-lots of boost, lots of compression, and precise injection events to make the C15 use fuel as efficiently as possible.
Does VVA consume more fuel?
A number of studies have demonstrated that the variable valve timing technology can potentially improve engine torque and power, reduce automotive emissions and fuel consumption [4, 5] .
Is VVA and VVT same?
Systems that provide Valve Timing Control (VTC)—also referred to as Variable Valve Timing (VVT) systems—are the most basic camshaft based VVA technology and simply change the timing of the valve events without significantly altering the lift.
What is a VVA solenoid?
The VVT solenoid is responsible for changing the position of the camshafts in the engine. It works on oil pressure, and can either advance or retard cam position to provide the right performance from the engine.
Is variable valve actuation good?
Variable Valve Actuation (VVA) makes the engine more flexible, offering better low-end grunt without compromising on top end performance. How Variable Valve Timing works: Essentially, the system works by shifting between two different intake cam lobes – one for low engine revs and the second for higher revs.
Is a 3406 Cat the same as a C15?
It’s a very popular engine for a reason, and they’re a consistent seller for us. The C15 was made to improve on the 3406E. One of the key improvements is that C15 engines see oil leakage less frequently than the 3406E.
