HIGH-SPEED FOUR-STROKE GAS ENGINES
High-safety and long-living gas motors were developed in Jenbach from a construction series of fast-running diesel motors with 6, 8, 12, and 16 cylinders and a ratio bore: stroke of 135 to 145 mm, for use in water pump systems. Their most favorable operation speeds are between 750 and 1800 rev/min with a speed control region of 1:2. Average effective pressures of 7.6 bar are achieved in suction operation, when charging with air load cooling, pressure of 11.6 bar are obtained. The specific consumption numbers are lowest for natural gas operation; although they are higher for other gases used, the knock-sensitive fuels are however cheaper, so that it appears economical to make use of these. The emission of harmful substances in the exhaust gases corresponds approximately to limiting values specified in the USA for diesel vehicles which lie far below the limit values for the exhaust gases of locomotive motors specified by the International Railway Association. The slight noise produced simplifies the noise abatement within as well as outside the machine room. The temperature of the exhaust gases is within a favorable range for both full and partial load.
