from the crankcase

  • These early engines used long studs from the crankcase to the cylinder heads.
  • Fuel was introduced into each cylinder direct from the crankcase meaning that only an exhaust valve was required.
  • In its next race, one of the Fiat's engine blocks detached from the crankcase.
  • The transfer ports act as a passage through which the air-fuel mixture moves from the crankcase into the cylinder above the piston.
  • After much testing, the solution was to seal the cam case from the crankcase and use a dual scavenge system.
  • As the piston travels downward, the fuel/air charge is pushed from the crankcase and into the cylinder.
  • The oil carried from the crankcase to the cylinder is used to lubricate the piston.
  • A crankcase ventilation system is a one way passage for gases to escape in a controlled manner from the crankcase of an internal combustion engine.
  • Without any springs or pushrods, the valve would pop open on the downstroke, allowing fuel to be drawn into the cylinder from the crankcase area.
  • The issue is that the air vented from the crankcase contains too much oil to easily pass through the swirl motor valves downstream of the turbo.
  • There were also designs that employed a scavenge pump or similar to remove oil from the crankcase and return it to the lubricating oil reservoir.
  • It usually breaks on the shaft protruding from the crankcase on the spline (it is still possible to clutch start them though).
  • With direct injection, only air (and usually some oil) comes from the crankcase, and fuel is not injected until the piston rises and all ports are closed.
  • It is an "open system" in that fresh exterior air is continuously used to flush contaminants from the crankcase and into the combustion chamber.
  • The large amount of material removed from the crankcase to provide the tunnel does not allow as much space for stiffening webs across the crankcase, so the overall rigidity of the crankcase may be less.
  • In conventional two-strokes, a portion of the fuel/air mixture entering the cylinder from the crankcase through the intake ports goes directly out, unburned, through the exhaust port.
  • Noted for their supercharged engines, this was their own patented design, in which the supercharging is achieved by transfer of gases from the crankcase to the cylinder.
  • Previous years of the ZX-6R's engines were all built from the same basic design, but the all-new engine for 2007 was redesigned from the crankcase up.
  • Like the Austro-Daimler, it was built up from the crankcase, which was milled from two pieces of cast aluminum bolted together at their midline.
  • However, oil was still not scavenging properly from the crankcase, and this was traced to an acoustic phenomenon due to the caliber of the scavenge inlet.
