ABSTRACT:
A combustion engine has a combustion chamber separated from the compression and expansion chamber(s). Passages are provided between the combustion chamber and the compression chamber(s) and the combustion chamber and the expansion chamber(s) with respective valves in the passages and inlet and exhaust valves provided in the combustion and expansion chamber. The combustion chamber maintains the combustion after passing fuel into the compressed air received from the compression chamber. The valves and piston heads are formed to prevent dead space in the cylinders in order to obtain a good efficiency by full discharge of the compressed air into the combustion chamber. Fuel cleaning means like, for example, a rotary separator and pure gas collector are provided in the combustion chamber to separate unclean fuel particles, as, for example, ash or sand in coal, from the burned gases and collect the unclean particles in separated collection spaces. The engine can thereby burn unclean fuels, as for example coal powder or coal sludge and the like. The valves can be timed for different styles of combustion cycles if so desired. The engine may use conventional four stroke or two stroke engine arrangements and provide them with combustion chambers, pistons and cylinder heads of the invention to modify them from gasoline combustion to coal combustion or other cheaper and more available fuels for the combustion in the compressed air.
