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.    

The combustion engine “Little Karl” is, as the name suggests, the small version of our popular combustion engine Karl. With this kit, particular emphasis was placed on the fact that it can be made in a small hobby workshop with a small lathe. Thanks to its simple construction, this model is also suitable for beginners in technical model making. In contrast to the large stationary engine Karl, this model does not have an ignition with a spark plug but rather a Glow plug. This circumstance makes both the construction of the model and its operation easier because the ignition timing does not need to be adjusted. Of course, this model also has speed control via Hit & Miss control. The combustion engine “Little Karl” with glow plug has a stable frame made of milled brass parts. The crankshaft is guided in two gunmetal plain bearings. The cylinder sleeve consists of a precision brass tube that no longer needs to be processed inside. An aluminum piston runs in the tube. The cylinder head and cooling jacket are also made of aluminum. Most other components such as the carburettor, tank, rocker arms and controls are made of brass. The entire motor is mounted on an aluminum base which in turn rests on two oak wooden runners. The two 80mm flywheels and the pulley are made of cast steel using the lost wax casting process and are of excellent quality. All materials required to build the combustion engine "Little Karl", such as screws, springs and ignition parts, are included in the kit. All milled parts are prepared so that they only need to be deburred and possibly drilled. All turned parts are included in the kit unmachined and must be manufactured according to the drawing. To build the Hit & Miss Motors requires a small lathe, a drill and a gas burner for soft soldering. The following hand tool is also required (tap M2, M3, M4, tap UNEF1/ 4 x 32, Dies M4, M6, reamer 3H7, 5H7, 6H7, 8H7) files and a drill set are necessary. All you need to wire the glow plug is a pair of side cutters, wire strippers and a soldering iron. You also need a baby battery with at least 3000 mAh. The battery is not included in the kit but can be ordered from us. If you would like to find out in advance which work steps you have to carry out when manufacturing this combustion engine, take a look at our Bengs model building magazine Construction report of the combustion engine "The Little Karl" with glow plug. On this page you can see the illustrated report on how the stationary motor material set is processed. Dimensions of the model combustion engine 'Karl': Height with wooden runners: 135mm Length overall: 200mm Width overall: 120mm Length without runners: 190mm Piston diameter: 20mm Flywheel D.: 80mm Speed: 600-1500 rpm Weight of the finished model: 1.8kg Hit & Miss Regulation With the hit & With this control you can limit the maximum speed of the engine. If the engine has reached too high a speed, a slide prevents the exhaust valve from closing. This means the engine runs freely. No compression can occur in the cylinder chamber and the engine neither sucks in fresh gasoline nor ignites the air-fuel mixture. The Hit & Miss regulation is called suspension regulation in German.

The Jonas vertical combustion engine was based on the appearance of the early diesel engines that were created at the beginning of the 20th century. A frame that has the shape of an A was typical. In addition, the early diesel engines were mostly long-stroke engines, which resulted in a slim and tall design. The overhead camshaft, which was driven by a long vertical shaft, was also typical. Back then, as now in our model, the speed was controlled via a centrifugal governor mounted on top of the vertical shaft. Our combustion engine runs on gasoline, but operation on diesel is not possible. Speed control via centrifugal governor Carburetor with adjustable throttle valve Cooling circuit with cooling water pump Fuel pump delivery rate adjustable Ignition timing adjustment Camshaft drive via screw wheel 45° With the material kit for the water-cooled 4-stroke engine "Jonas" you can build a fully functional internal combustion engine yourself.

With this set of cast parts you have the opportunity to build a prototypical model engine of the type that was used as a large engine at the beginning of the last century (e.g. to generate electricity in factories). The large piston stroke and large bore enable a speed of less than 130 rpm. The quiet and slow running of the engine arouses true enthusiasm among connoisseurs. The valves are controlled via a timing chain that drives the camshaft. The dimensions of the gas engine are already clear from the weight. It weighs around 50 kg. With this engine, a true-to-life power plant can be built to generate electricity. This set of castings was previously sold by the Ravensburger Dampfmodelle company. This casting set, drawing and spare parts are now available from us in the Bengs Modellbau online shop. We supply most of the special parts needed to build the engine. You can use the components we offer as ignition. Here you can find the parts for the ignition (Ignition coil , Interrupter, Kondensator, Spark plug).  The castings are molded and cast by hand in a small foundry in Germany. Most of the castings are made of GG25, the cylinder head is delivered in cast aluminum.

The 4-cylinder in-line engine "Marc" is based on a historical model. The model was a four-cylinder in-line engine that was manufactured by the American company Holt at the beginning of the 20th century. This engine was mainly used in bulldozers and tracked tractors. This engine was available in 2, 4 and 6 cylinder versions. In 1925, the Holt company became the Caterpillar company, which still exists today. The engine does not consist of a cast engine block, as was usual later, but still has individual cylinders. This design is visually very appealing and makes it possible to offer the engine as a material kit. Speed control via centrifugal governor Carburetor with adjustable throttle valve Cooling circuit with cooling water pump Cooler with fan With the 4-cylinder in-line engine "Marc" material kit, you can build a fully functional combustion engine yourself. The material kit contains all the necessary parts including the ignition. The engine has a functioning speed control using a centrifugal governor.

This casting set was designed on the model of a Dürkopp gas engine. The finished model has an impressive total height of 430mm and many special details. This casting set was previously marketed by Ravensburger steam models. From now on this cast kit is available from us. To build this casting set, you should already have experience in this model construction area. The flywheel with 280mm diameter requires a large and stable lathe, with a sufficiently large lining and planar disc. You also need a larger milling machine to finish the castings. This engine is a special construction, the crankshaft lies above and the piston plunges down into the cylinder. This type of motor is called the plunger motor. A cam disk is driven via two bevel gears, through which the inlet and outlet valves are actuated. The valves are not mounted in the cylinder chamber, as are customary today, but are located outside in their own valve housings. In addition, this motor is equipped with a centrifugal governor, which can be used to regulate the amount of the incoming gas. The Dürkopp immersion piston engine has been designed for operation with gas. It can be operated directly with gas from a propane bottle. Of course, this engine can also be operated with petrol. For this, however, the gas mixer must be exchanged for a carburettor. Our experience has shown that this engine runs with gas much smoother and more beautiful. We recommend operating with gas. Required tools and machinesFor the construction of the combustor, an extensive workshop, with a large lathing machine and a medium-sized stable milling machine is needed. The lathe should be able to machine a flywheel with an outer diameter of 300 mm. For machining the castings on the lathe, a planar disk should also be present. In addition, a stator drilling machine and a torch for soldering larger parts will be available. Furthermore, hand tools (taps M2, M3, M4, M6x0,75, M10x1 / cutter M2, M3, M4, M8, M6x0,75, M10x1 / reamers 3H7, 4H7, 5H7, 6H7,15H7 files, drill set) are necessary , To solder the ignition, a soldering iron is required for this model. We have prepared for you an extensive construction report of the Dürkopp gas engine. The building report is subdivided into subassemblies and is designed to assist you in the manufacture of the engine. Furthermore, you can see in the building report whether your machine park is of sufficient size.
