  2. Long-bolt engine - Wikipedia

    en.wikipedia.org/wiki/Long-bolt_engine

    A long-bolt or through-bolt engine is an internal combustion piston engine where, following usual practice, the cylinder head is held down by bolts or studs. Conventionally the cylinder head is bolted to the cylinder block and the crankshaft main bearings are in turn bolted to the crankcase by separate bolts. [notes 1] In the long-bolt engine ...

    en.wikipedia.org/wiki/Cylinder_head

    In a piston engine, the cylinder head sits above the cylinders, [1] forming the roof of the combustion chamber.In sidevalve engines the head is a simple plate of metal containing the spark plugs and possibly heat dissipation fins.

  4. Cylinder head porting - Wikipedia

    en.wikipedia.org/wiki/Cylinder_head_porting

    Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads , as manufactured, are usually suboptimal for racing applications due to being designed for maximum durability.

    "Waisted" or "undercut" studs, as engine cylinder head retainers. With respect to shape, stud bolts a.k.a. studs are categorized into three basic types: "fully threaded stud bolts", "tap-end stud bolts", and "double-end stud bolts". Each of these studs have different application.

  6. Hydrolock - Wikipedia

    en.wikipedia.org/wiki/Hydrolock

    If a cylinder fills with liquid while the engine is turned off, the engine will refuse to turn when a starting cycle is attempted. Since the starter mechanism's torque is normally much lower than the engine's operating torque, this will usually not damage the engine but may burn out the starter. The engine can be drained as above and restarted.

  7. Heron cylinder head - Wikipedia

    en.wikipedia.org/wiki/Heron_cylinder_head

    The head is machined flat, with recesses only for inlet and exhaust valves, spark plugs, injectors and so on. The combustion chamber itself is contained within a dished depression in the top of the piston. The Heron head is suitable for petrol and diesel engines, for ohv and ohc valve-gear, and for small and large engine displacement capacities.
