What happens when you have a variable length intake manifold?
A variable intake can create two or more pressurized “hot spots”, increasing engine output. When the intake air speed is higher, the dynamic pressure pushing the air (and/or mixture) inside the engine is increased.
What kind of intake manifold does a Volvo 850 use?
Volvo — V-VIS ( Volvo Variable Induction System) Volvo B52 engine as found on the Volvo 850. Longer inlet ducts used between 1,500 and 4,100 rpm at 80% load or higher. ^ Hirschfelder, Klaus; Völkl, Werner; Kühnel, Hans-Ulrich; Sinn, Walther; Huck, Armin (March 2002).
What are the effects of variable intake geometry?
There are two main effects of variable intake geometry: Variable geometry can create a beneficial air swirl pattern, or turbulence in the combustion chamber.
What kind of vibrations can a suction pump cause?
Improper design of the suction piping or sump, or inadequate pipe support exterior to the pump, can cause hydraulic disturbances that manifest in chronic and eventual destructive random frequency vibrations.
How big are the intake valves on a Honda H22A?
For a cold engine, intake valves clearance should be 0.15-0.19 mm, exhaust valves clearance – 0.17-0.21 mm. The size of H22A engine stock fuel injectors (until 1997) – 345 cc. Engines made after 1997 used 290 cc fuel injectors.

How tall is the cylinder block on a Honda H22A?
The H22 cylinder block height was 219.5 mm. Until 1997 all H22A used closed deck cylinder blocks, and 1997 to 2001 — open deck cylinder block. A 90.7 mm stroke crankshaft and balancer shafts were installed. H22A piston rod length was 143 mm, the bore was 87 mm, and their compression height was 31 mm. This provides the displacement of 2.2 l.
