Internal Combustion

Internal Combustion Engines are basically any device which uses the explosive combustion of fuel to push a piston within a cylinder. Examples of internal combustion fuels include:

  1. Petrol/Gasoline
  2. Diesel
  3. Kerosene
  4. Aviation Gas (AVGAS)

In this section of Steam & Engine you will find both details on the processes and engines, but examples of the usage of those engines.

Remember to also check the Registrars page (menu item at left) and the Manual Exchange (menu item at left) for more information. If you have an engine it can be to your advantage to register it with a registrar in order to find other people who also have your engine type/style/brand. It can also help out if your engine is ever stolen.

To run on petrol

  1. Open the main needle valve 2 turns
  2. Oil the shaft where the hand crank fits on and inside of the crank handle
  3. Fit the crank handle
  4. Using the hand lever, manually pump the combined fuel/oil pump until the starting bowl in the carburettor fills with petrol
  5. Hold the crank handle with your thumb folded in (so it does not get ripped off if the engine fires backwards)
  6. Close the choke lever completely
  7. Slowly crank the engine until it fires (you have to crank slowly because it has an impulse trip on the magneto, and if you crank too fast it will not trip, but also will not be fast enough to fire the magneto normally)
  8. Immediately it fires pull off the crank (if it did not already throw it off - mine usually does)
  9. Slowly close the needle valve until the engine fires evenly and there is no more black smoke from the exhaust
  10. After the engine warms up open up the choke slightly to give it a little more air - you may need to readjust the needle valve to get clean exhaust again…

The instructions for starting an engine are in a way particular to each engine style. I'll go through some of the basic starting instructions for a few of the engines I own - you can pick the one that seems to suit your circumstances and go for it. In each of the starting instructions I'll assume that you've already make sure things such as the fuel tank tap are open :)

  1. Fill fuel tank.
  2. EVERY time remove the ignitor and clean carbon off of the floating rod!
  3. Connect battery and turn on switch.
  4. Open petcock on ignitor and confirm spark. (Don't view too close in case it fires!) Close petcock.
  5. Turn on fuel and prime the mixer by holding in button on bottom of mixer until fuel begin to dribble out around button.
  6. Turn the flywheels slowly backwards until against compression.
  7. Find a friend to turn the other flywheel.
  8. Turn the flywheels as fast as possible the correct direction, through the intake stroke (gaining momentum) and muscle it through the compression stroke.
  9. Continue to muscle it through until it fires (usually 1st or second time around)

From dead cold :
  1. Retard the spark at the magneto by flipping the lever forward.
  2. Open the fuel needle screw 5 nut facets (almost 1 turn)
  3. Open the primer cup on the cylinder just slightly to allow compression release.
  4. Pull the flywheels through compression 5 times (this gets kerosene to the mixer)
  5. At the start of the intake stroke - put a small squirt of gasoline on the primer cup.
  6. Suck in the gasoline - and - on the compression stroke, pull it through compression.  It will fire.
  7. Once it fires - Advance timing - close primer cup. Being that it's burning Kerosene - I have to keep mind and choke the mixer by covering it with my hand just enough to keep it running. I do this for a few minutes until it warms up a little.…

  1. 1. Turn all grease cups, oil lubrication points.
  2. Hold intake valve open and rotate engine just past top dead center on the compression stroke.
  3. Turn on fuel and ignition switch.
  4. Slide roller for exhaust valve to the rear for compression release mode.
  5. Place right hand on the flywheel spoke in the 3 o'clock position, palm down.
  6. Rotate flywheel two complete revolutions and engine should be running, if not pull exhaust roller back to the release position and complete the cycle again.
  7. If it is still not running ( usually only when the engine is cold), turn off the fuel and rotate a couple more times while in the compression release mode. When it fires, let it fire twice then turn on the fuel and adjust speed.
  8. Step back and smile widely, enjoy.
