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. A cooling water pump pumps water through a radiator, where the cooling water is cooled down by the fan and then flows back into the cylinder jacket. The engine is equipped with glow plugs. The glow plugs come with four Batteries operated. All components for producing the ignition are included (batteries are not included).Dimensions of the model combustion engine 'Marc': Height with wooden base: 310mm Length: 450mm Width: 180mm Piston diameter: 23mm Flywheel D.: 1x140mm 1x80mm Speed speed: 200-1000 rpm Weight: 9.1kg The engine stands on two oak runners. The engine block is screwed together from milled parts. The base plate for the cylinders is made of steel, the bearing blocks that hold the crankshaft are made of aluminum. This unit is then provided with finished lasered and folded sheets. The cylinder sleeves are made of brass, the inside diameter no longer needs to be machined. The cylinder head and cylinder are included as material sections and must be machined on the lathe. The remaining components are mainly made of brass. The crankshaft is made from individual segments. No milling machine is required to produce the crankshaft either. It can be built entirely on the lathe. Further information can be found in our build report for the four-cylinder engine. The two flywheels are available in the quality we know. Both flywheels are made of cast steel. The speed of this model is controlled via the carburettor. You can regulate the amount of air supplied. The carburettor is connected to a centrifugal governor via a linkage. This means you can set the engine to a desired speed, which is then maintained under load using the centrifugal governor.

With this material kit you can make a blowtorch yourself. The blowtorch is model size and has a total height of 125 mm. The blowtorch is mostly made of brass. The handle and the handwheel for adjusting the flame size are made from the included oak wood. The finished blowtorch also works in the model just like an original blowtorch. You can use the torch for brazing, soft soldering, paint stripping and for operating glow tube igniter engines. Of course, this beautiful blowtorch is also suitable for the model making display case just to look at. A blowtorch is a gas burner that was originally powered by gasoline or spirit. The blowtorch is not only used for soldering but also as a heating lamp for preheating glow-head engines. An alcohol-powered blowtorch does not start by itself but must be preheated. Due to the complicated handling, spirit and gasoline-powered blowtorches were replaced in the 1970s by blowtorches with butane as a fuel. The alcohol-powered blowtorch remains a fascinating tool to this day.  All milled parts and all stamped parts (tank base and tank cap) are included in the kit ready-made. All turned parts are included in the delivery as raw material. Of course, as with all other Bengs model building material kits, you will also receive all the necessary sealing elements, screws and fiberglass wicks. A 0.38 mm drill is required to build this kit.

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.

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 misfire control was mainly used in the USA by various companies for internal combustion engines from 1890 to 1940.

With this kit you can build a rotary lever press on a model scale. The special thing about this kit is that all parts are finished and the parts only need to be deburred, soldered and assembled. This means that for the first time you can make a Bengs model building kit without a lathe or drill. The rotary lever press is a smaller model version of the rotary lever presses. These presses were used in blacksmiths and craft businesses for a long time. The small model is suitable for workshop dioramas or similar applications. In terms of scale, it fits well with our Nils eccentric press or our Leni steam engine. The model is made exclusively of brass. To build the kit, all you need is a file for deburring and a soldering torch for soldering the frame.

The original Britain, America and France had introduced several notable hot air engines by 1850. Surprisingly, Germany had not produced any significant innovations in this area up to this point, it was not until 1867 that the German Wilhelm Lehmann produced a significant innovation in the field of hot air machines. A late innovation, but an impressive one: the Lehmann air expansion engine!The model Stirling engine Rainer The model of the Lehmann Stirling engine has a total length of 285 millimeters. When designing our Stirling engine, we tried to keep it as close to the original as possible. However, it is not a 100% copy of the original. Our model is operated with an alcohol burner. The burner is firmly screwed to the oak base plate. The cooling jacket, which was a solid casting in the original, is assembled from several milled brass parts and soft-soldered. Just like the original Lehmann Stirling engine, the model has a functional centrifugal governor that can regulate the speed of the hot air machine. As with the original, the centrifugal governor opens a valve that allows the air in the Stirling's working chamber to escape. The 140 mm diameter flywheel is made from a very clean cast steel. In addition, the Stirling engine has a 48mm pulley that could be used to drive small drive models, for example.Speed control via centrifugal governor This Stirling engine has a working centrifugal governor. When the speed is sufficient, the balls of the regulator rise. This moves a lever that operates a valve. If the valve is opened, the working air can escape from the displacement cylinder. Due to the reduced pressure, the Stirling process no longer works optimally and the engine reduces its speed. To set the desired speed, you can adjust the spring tension of the valve using a handwheel during operation.Dimensions of the model Stirling engine Base plate: 255mm x 120mm Flywheel: 140mm Pulley: 48mm Total height: 210mm Working piston: 28mm Displacer piston: 25mm Length overall: 285mmThe “Rainer” Stirling engine material kit is included in delivery Wooden base plate Finished milled parts Brass, steel, stainless steel and silver steel Raw material for the turned parts Cylinder sleeve made of precision tube flywheel All required screws, nuts, gaskets, grub screws and wick Construction plan model Stirling "Rainer" drawings (14 sheets) and construction instructions (9 sheets)

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. The material kit contains all the necessary parts including the ignition. The engine has functioning speed control using a centrifugal governor. A cooling water pump pumps water through a radiator into the cylinder jacket and back again. The engine also has a fuel pump that pumps the fuel towards the carburettor into an intermediate tank. The pumping volume of the fuel pump can be adjusted as required. The breaker ignition is located in the cast base. The ignition is supplied with voltage via a 12 V 2 A power supply. The power supply is also included.Dimensions of the model combustion engine 'Jonas': Height with wooden base: 500mm Dimensions of the base plate: 350mm x 210mm Piston diameter: 25mm Flywheel D.: 200mm Speed speed: 200-600 rpm Weight: 11.8kg The machine base of the vertical stationary motor is a heavy gray cast iron base. This heavy base gives the model sufficient stability. The piston of the combustion engine is also made from gray cast iron round material. In this engine the piston also has a piston ring. The piston ring is already included in the kit. A hydraulic cylinder tube is used as a cylinder, which is already finished on the inside and has an excellent surface. The cylinder head is made of aluminum, the cooling jacket is hollow and is flushed with cooling water via a cooling water pump. The 200mm flywheel is made of gray cast iron and can be ordered pre-machined upon request. Most of the attachments and the machine frame are made of brass.Speed control The speed of this model is controlled via the carburettor. By being able to regulate the amount of air supplied. The carburettor is connected to a centrifugal governor via a linkage. This means you can set the engine to a desired speed and this is maintained even under load using the centrifugal governor.
