NOISE ABATEMENT ON DIESEL LOCOMOTIVES. THE DIESEL ENGINE AS A SOURCE OF NOISE
Following measurements taken on diesel engines and analysed in Report Nos. 2 and 3, an attempt has been made at reducing the noise caused by diesel engines by a treatment of the parts found to be the noisiest ones, such as injector pumps, cylinder caps, inspection covers and air intake collectors. The advantages obtained from each of the improvements effected are discussed in Part 2. The injector pumps have been dealt with separately and form the subject of Part 1. In Part 3, the noise measured at 8 points on an MGO engine is compared to that caused by a PA 4 engine. Finally, in the fourth part an attempt has been made at explaining the differences between the noise caused by the three engines and a comparison has been made between the acoustic output and efficiency and between the constructional differences.
