A mechanics course in a box. A very instructive gift! After patiently assembling the elements of this 4-stroke Engine, budding mechanics can see pistons, track rods, valves and cylinders working, adjust the starter, synchronise the spark plugs and see it start like a real motor. This toy works on the principle invented by Alphonse Beau de Rochas in 1862: induction is followed by compression then the combustion produced by the spark plug ignites the mixture and is finally expelled via the exhaust. This cycle, reproduced several thousand times per minute, is what makes a car move. This amusing and instructive set contains all the material necessary to become an expert mechanic and know all about the internal combustion engine: more than 100 parts to assemble, and the essential tools and a detailed manual with assembly instruction and technical explanations are all included.
