The engine without the cylinders’ head


The mankind uses traditional valve internal combustion engine, whether petrol in it is applied or diesel fuel, already more than century. But, despite its popularity, for a minute doesn’t refuse idea to invent the engine more rational. The most known attempt – Wankel rotary engine known on cars “Mazda” RX 7 and RX 8. Alas, the company-manufacturer has informed recently that stops workings out because of insuperable technical difficulties with axial seal of the rotor and, as consequence, low motor potential. And can Wankel engine didn’t become popular because of the unusual design: people had time get to like crankshafts, connector rods with pistons and a four-stroke principle.

If to look at modern lines of working out of engines it is appreciable that the basic attention is given to the gas distribution mechanism: the number of valves and cam-shafts increases, change of phases depending on number of turns and loading is applied, electronic control etc. An internal combustion engine’s head all becomes more difficult and, certainly, more expensively. Its price reaches half of cost of the modern engine, and repair demands high qualification and unconsciously expensive.

So why not to refuse a cylinders’ head commonly?

We assert that the simple four-stroke engine with usual crank-and-rod mechanism, pistons and spark plugs (or atomizing nozzle for diesel fuel) can be structurally changed and work without so habitual head – without valves, pushers, gas distribution shaft, chain or belt and to that similar. There is no necessity for nothing to burn fuel for a drive of these mechanisms!
