Stationary engine Karl with Hit & Miss regulation

Product information "Stationary engine Karl with Hit & Miss regulation"

Stationary engine with hit and mismatch were used from 1890 to 1940 for a variety of tasks. The design with lying cylinder, open crankshaft and two flywheels was one of the most popular. These engines have been used in many farms to drive threshing machines, pumps, or grain grinders. But also in many craft and industrial engines, these combustion engines have been used in various sizes. Particularly in the American area, the speed control system has been widespread through a misfire control. The open crankshaft and the open rocker arms allow a very good view of the workings in an internal combustion engine.

With the material kit for the internal combustion engine "Karl" you can build a fully functional combustion engine. The material kit contains all required parts including the ignition. The engine has a functioning speed control, which is controlled by a hit and miss misfire control. The ignition is concealed in the base of the machine, as well as in the wooden box behind the machine base.

Dimensions of the model internal combustion engine 'Karl':

  • Height with wooden runners: 192mm
  • Overall length: 440mm
  • Width overall: 180mm
  • Length without skids and wooden box: 283mm
  • Dia. Piston: 25mm
  • Flywheel D .: 140mm
  • Speed: 600-1500 rpm

The machine foot of the station motor is a heavy gray cast iron base. The piston of the machine is also made of gray cast iron round material. The cylinder is made from a hydraulic cylinder tube which is already finished on the inside and has an excellent surface. The cylinder head and cooling jacket are made of aluminum to guarantee good heat dissipation. The flywheels are made of cast steel in the usual Bengs model construction quality. Most attachments and machine frames are made of brass.

All necessary materials for the construction of the internal combustion engine "Karl" Screws, springs and ignition parts are included in the kit. All milling parts are prepared so that they are only deburred and possibly drilled.

Construction of the Hit & Miss engine requires a lathe, a drilling machine and a gas burner for soldering. Furthermore, the following hand tools still needed (taps M2, M3, M4, M8x0,75, M10x1 Dies M2, M3, M4, M8x0,75, M10x1 Reamer 3H7, 4H7 6H7, 10H7) files and a set of drill bits needed. Only one side cutter requires a stripping plier and a soldering iron for wiring the ignition.

If you want to find out in advance what steps need to be performed in the production of this engine that you see in our Bengs model magazine the building report from the 4-stroke stationary engine "Karl" on. On this page you can see the illustrated report how the station motor is edited.

Included in the delivery are:

  • Finished CNC milled milling parts
  • Raw material for the turned parts
  • Raw casting for the flywheels
  • Raw casting for the belt pulley
  • Two wooden runners
  • All required screws, nuts, sprockets and ball bearings
  • Drawings Internal combustion engine "Karl" (24 sheets) and english construction manual (11 sheets)
  • Wooden box for ignition
  • Ignition coil, condenser, spark plug and breakers
  • All required cables for the ignition
  • Power supply for the ignition

Hit & Miss regulation

The Hit & Miss regulation can limit the engine's maximum speed. When the engine has reached an excessive speed, a slider prevents the exhaust valve from closing. Thus the motor runs freely. No compression in the cylinder chamber can occur and the engine does not suck up any fresh gasoline or ignite the air fuel mixture. The Hit & Miss regulationt is mentioned in the German suspension rules. The intermittent control system was used from 1890 to 1940 mainly in the USA by different companies with internal combustion engines.

Soft soldering paste
Soft soldering paste for brass, copper, steel and silver steel. The paste is applied thinly to the parts to be tinned and heated with a brazing lamp. For large-area soft soldering, it is optimal to tin- the parts beforehand. For example, we use the paste to pre-tine the cylinder and the mirror when constructing a model steam engine. The tinning paste can also be used optimally as a flux substitute. The soft soldering paste is excellently suitable as corrosion protection for steel parts. Bengs Modellbau uses the zinc paste for steel cylinders with a cooling water jacket. For example in the Flammenfresser Kurfürst. Stirring the paste before use is not necessary! The soft soldering paste may be diluted with water.

screw tap fine thread
You can choose between two different types of taps, namely hand thread drills (pre-cut and finished cutters) and machine thread drills (incision thread drills). Both the manual thread drills and the machine thread drills have a square cut. Fine threads are very suitable for the use of model making since the threads are much finer and more filigree. However, fine threads are also used in the automotive and pneumatic industries. We only supply taps of industrial quality from a German manufacturer. You can also find matching winds in our shop. With square cut industrial quality Made in Germany The following fine thread taps are always available: 2-thread hand thread drill for fine thread  M4x0,5  M5x0,5  M6x0,5  M6x0,75  M7x0,5  M8x0,75  M10x1 1-turn machine thread tap for fine threads  M4x0,5  M5x0,5  M6x0,5  M6x0,75  M8x0,75  M8x1  M10x1

Metric fine threads
These dies for metric fine threads are made from HSS steel. We only supply you with cutting dies and taps of industrial quality, so that you can enjoy your tools for a long time. Fine threads are well suited for use in model making because the threads look more delicate. Bengs Modellbau likes to use fine threads on tank caps, coolant caps, screw connections or adjustment spindles. You can of course also order matching die holder in the Bengs model shop. Please always use cutting oil when using fine thread dies. Industrial quality The following thread cutting dies are always available: Other sizes available at short notice upon request. Fine thread dies  Die cutting iron M4x0.5 / dimensions 20mm x 5mm  Die cutting iron M5x0.5 / dimensions 20mm x 5mm  Die cutting iron M6x0.5 / dimensions 20mm x 7mm  Die cutting iron M6x0.75 / dimensions 20mm x 7mm  Die cutting iron M7x0.5 / dimensions 25mm x 9mm  Die cutting iron M8x0.75 / dimensions 25mm x 9mm  Die cutting iron M8x1 / dimensions 25mm x 9mm  Die cutting iron M10x1 / dimensions 30mm x 11mm

Machine reamers
Machine reamers for the production of dimensionally accurate bores. By rubbing with a reamer, not only good shape and dimensional accuracy, but also good surface quality is achieved. This is of crucial importance when manufacturing sliding bearings in mechanical engineering and model building. The long cutting edges of the reamer have a left-hand twist, which causes the resulting chips to be discharged downwards when rubbing. Thus, a scratching of the bore surface by the resulting chips is avoided. Our machine reamers have industrial quality and can be used to grind drillings in steel, brass, copper, cast iron, aluminum and stainless steel. Please always use enough cutting oil when rubbing, which considerably increases the service life of the reamer. In model construction, these reamers are suitable for producing piston rod guides for steam engines, Stirling engines and flame eaters. The reamers are also ideal for producing bearing blocks with plain bearings or for producing cylinders with a very clean surface. If you produce the axis bore with a reamer for flywheels, the flywheel runs particularly round. Provided you have the flywheel without impact in the lathe. The machine reamers can be used both on a lathing machine and in a column drilling machine.   With long cutting edges and link spiral Maximum roundness accuracy industrial quality   These reamers are available: Reamer 1H7 / Shaft 1mm / cutting length 16mm  Reamer 1,5H7 / Shaft 2mm / cutting length 21mm  Reamer 2H7 / Shaft 2mm / cutting length 26mm  Reamer 3H7 / Shaft 3mm / cutting length 29mm  Reamer 4H7 / Shaft 4mm / cutting length 46mm  Reamer 5H7 / Shaft 5mm / cutting length 57mm  Reamer 6H7 / Shaft 6mm / cutting length 56mm  Reamer 7H7 / Shaft 8mm / cutting length 71mm  Reamer 8H7 / Shaft 8mm / cutting length 80mm  Reamer 10H7 / Shaft 10mm / cutting length 91mm  Reamer 12H7 / Shaft 10mm / cutting length 110mm  Reamer 14H7 / Shaft 14mm / cutting length 112mm  Reamer 15H7 / Shaft 14mm / cutting length 114mm  Reamer 16H7 / Shaft 14mm / cutting length 123mm  Reamer 18H7 / Shaft 14mm / cutting length 135mm Reamer 20H7 / Shaft 16mm / cutting length 145mm  Reamer 25H7 / Shaft MK3 / cutting length 174mm  Reamer 26H7 / Shaft MK3 / cutting length 178mm
