the shaft.
The advantages of new coal gas-based engine in contrary to steam engines were first of all possibility of its considerably easier exploitation, and coal gas engine was not so dangerous because it had no steam-boiler and fire box. Though the coal gas engine remained as heavy as steam engine. One produced power unit cost seven times more expensive then of the steam engine. And the coefficient of efficiency came up to just 0.04 – the rest energy was wasted into the exhaust. When the shaft speed reached 100 ev/min the ignition worked irregularly. More over engine cooling system demanded some 120 cubic meters of water per hour! AS the gas temperature get to 800 degrees the valve suffered overheats and held up.
Nevertheless it was the only well working coal-based engine and after it was presented in 1862 at the Paris World Exhibition its popularity grew. Only in 1964 there were made 300 Lenouar engines. Having become rich Lenouar stopped further attempts to improve the invention and it was soon inevitably replaced by more perfect coal gas engine model devised by inventor from Germany, August Otto.
