The Brons system

Repairs and parts.


2 spraying-cups
2 pre-chamber cups

Diesel engine from Appingedam (Holland)

After two years of truying and testing, the first Brons spraying-cup engine runs well!
And so, Mr. Jan Brons got a german patend in the year 1904 to protect his invention.
Lotīs of old engineīs all around the world are still working with this "Brons" or "Brons/Hvid" system.
Brons pre-chamber engines stood not only in ships but they were also used for pumping and factory work.
The factory in Appingedam makes no longer Brons engines but is taken over by the Waukesha Engine division.




Brons spraying-cup unit
The Brons engine details are as follows:
The Brons engine has in the sprayer one valve (C) and a needle; the latter, moved by the governor (O), controls the quantity of combustible. The lower end of the sprayer is provided with a cup with holes (B), which partly protrudes into the cylinder. During the first stroke the sprayer-valve is open and the necessary quantity of fuel flows into the cup by gravity and suction. During the second stroke the valve is closed, the compression raises the temperature of the air and causes self-ignition of the partly vaporised fuel in the cup. By the force of the explosion the main part of the remaining liquid combustible is injected and sprayed through the small holes (A) into the cylinder, where immediately the main combustion takes place. The moment of ignition is regulated at the factory and no change or derangement is possible.
